Executive Summary The purpose of this report is to provide information to several stakeholders and to satisfy the regulatory requirements of the Safe Drinking Water Act (SDWA) including the Drinking Water Quality Management Standard (DWQMS), and regulatory reporting required under O.Reg. 170/03 (Section 11 and Schedule 22). The report is a compilation of information that helps to demonstrate the ongoing provision of a safe, consistent supply of high quality drinking water to customers located within the City of Guelph and the Gazer Mooney Subdivision (located in the Township of Guelph/Eramosa). Water Services is a municipally-owned and -operated water utility established in 1879. The Guelph Drinking Water System is a Class IV Water Distribution and Supply Subsystem and is composed of water supply and treatment facilities and a water distribution system. The Gazer Mooney Subdivision Distribution System is a Class I distribution system. Both the Guelph Drinking Water System and the Gazer Mooney Subdivision Distribution System are required to comply with the Safe Drinking Water Act (SDWA) and Regulations as well as requirements contained in Permits to Take Water (PTTW), Municipal Dinking Water Licences (MDWL), and Drinking Water Works Permits (DWWP). Having met the quality management system requirements of the SDWA, Guelph Water Services is an accredited Operating Authority with an up-to-date Operational Plan (OP). The OP is available upon request from Guelph Water Services. The source of Guelph’s drinking water is a series of 21 operational groundwater wells and a shallow groundwater collector system consisting primarily of true groundwater sources, with some “groundwater under the direct influence of surface water with effective filtration” (GUDI-WEF) sources (i.e. Carter Well field, Arkell 1 and the Glen Collectors). The City has approximately 40,583 fully metered water service connections, 545 kilometres of underground watermains, and an approximate population of 124,000 within the City of Guelph. The Gazer Mooney Subdivision has approximately 70 fully metered water service connections, 2 kilometres of underground watermains, and an approximate population of 200. As the Operating Authority for both systems, Guelph Water Services is annually inspected by the Ontario Ministry of the Environment (MOE) for compliance with regulatory requirements. In Jun. 2012, both the Guelph Drinking Water System and the Gazer Mooney Subdivision Distribution System were inspected (for the period of Jun. 2011 to Jul. 2012) and received compliance scores of 96.4% and 100% respectively. There was one incident of non-compliance that occurred on June 11, 2012 when a UV treatment failure occurred and was off-line for 6 minutes. Back-up systems functioned normally and chlorine disinfection was not affected. From Jan. 1 to Dec. 31, 2012, Guelph Water Services reported four (4) Adverse Water Quality Incidents (AWQI) in the Guelph Drinking Water System. Three of the four incidents involved the detection of Total Coliform in the distribution system above the regulatory limits. In all these cases, re-sampling did not confirm the presence of Total Coliform. One of the four AWQI’s was a precautionary report resulting from significant repair activities.

In conjunction with Wellington-Dufferin-Guelph Public Health and the MOE, all appropriate corrective action and reporting were completed. There were no AWQIs in the Gazer Mooney Subdivision Distribution System in 2012. Water Services’ risk assessment updates, emergency response testing and audits help facilitate continual improvement of processes and systems through the implementation of corrective actions. The system is operated to meet daily, seasonal, and other operational demands (fire demands) with various combinations of supplies in operation at any given time. From Jan. 01 to Dec. 31 of 2012, a total of 16,560,328 cubic metres (16.6 billion litres) of water was treated and pumped to the system. The average daily water demand was 45,247 cubic metres (45.2 million litres). The highest daily use of water occurred on July 12, when 58,764 cubic metres (58.8 million litres) of water was pumped. The minimum day production of water was 31,536 cubic metres (31.5 million litres) and occurred on Dec. 25, 2012. All water provided to the Guelph Drinking Water System and the Gazer Mooney Subdivision Distribution System was treated with sodium hypochlorite (for chlorine disinfection) with some sources also using ultraviolet disinfection (UV). All supplied water was tested and met all regulatory standards. The City Guelph Water Services maintained the drinking water system in a fit state of repair and followed best industry practices during the repair and maintenance of the system. Details of ongoing and emerging water quality and supply initiatives are outlined in section j) of this report and include successful programs related to: water conservation, source water protection, and lead reduction. Water Services continues to implement recommendations of the Water Conservation and Efficiency Strategy, is finalizing the Source Protection Plan with the Lake Erie Source Protection Committee, continues to invest in the Arkell Afforestation Project (to protect the Arkell Wellfield’s source water quality), and is successfully implementing its extensive Lead Reduction Plan in accordance with the regulatory relief provisions of the SDWA. The Lead Reduction Plan is partially grant-funded, and from Jan. 1, 2012 to Dec. 31, 2012, there were 68 full or partial replacements of lead service water lines. Water Services’ Operational Testing and Adaptive Management Plan continues to assess the aquifer and pumping conditions to determine a sustainable capacity with respect to environmental conditions in the area. Infrastructure review occurs regularly between Engineering and Water Services to optimize priority projects and minimize common costs. The Water Supply Master Plan is due to be updated in 2013. The City maintained a robust backflow prevention program in 2012 overseeing 2,535 facilities with 5,771 backflow prevention devices installed. There were no reported backflow incidents. The City has completed this Annual & Summary Report to satisfy the regulatory requirements of the Safe Drinking Water Act, O.Reg 170/03 (Section 11 and Schedule 22).

Systems Overview Guelph Drinking Water System The mission of the City of Guelph Water Services (“Water Services”) is to provide customers and the community with a safe, consistent supply of high quality drinking water while meeting, exceeding, and continually improving on legal, operational, and quality management system requirements. Water Services provides and promotes reliable, cost-effective systems for the safe production and delivery of consistently high quality water. Water Services is a municipally-owned and -operated water utility established in 1879. The Guelph Drinking Water System is a Class IV Water Distribution and Supply Subsystem and is composed of water supply and treatment facilities and a water distribution system. From Jan. 1, 2012 to Dec. 31, 2012, forty water operators and staff were certified to operate and maintain the water systems. In Apr. 2009, Water Services received third-party accreditation that satisfied part of the requirements under the Municipal Drinking Water Licensing Program. Third-party system document audits of Water Services’ Quality Management System were undertaken in 2010. On-site audits by the accreditation body are still pending. The distribution infrastructure (including watermains, valves, fire hydrants, services, and meters) serves approximately 124,000 people within the City of Guelph. All new components meet NSF 61 requirements or approved equivalents and are installed and maintained in accordance with approved industry standards. The system is fully metered. The Guelph Drinking Water System distribution system is comprised of the following infrastructure:

o 6.38 kilometres of 900-1,050 mm diameter water supply aqueduct; o 5 underground storage reservoirs with a combined approximate capacity of 48,000 cubic metres (48

million litres); o 3 water towers with a combined approximate capacity of 11,200 cubic metres (11.2 million litres); o approximately 545 kilometres of buried watermain with a diameter < 900 mm; o approximately 4,015 watermain valves; o approximately 2,660 fire hydrants; and o approximately 40,583 water services and water meters.

The source of Guelph’s drinking water is a series of 21 operational groundwater wells and a shallow groundwater collector system consisting primarily of true groundwater sources, with some “groundwater under the direct influence of surface water with effective filtration” (GUDI-WEF) sources (i.e. Carter Well field, Arkell 1 and the Glen Collectors). The Guelph Drinking Water System uses 12 per cent Sodium Hypochlorite (that is NSF 60 certified) for primary disinfection at 10 locations and for multi-barrier primary disinfection at three locations. At three locations, ultraviolet light is also applied as part of multi-barrier primary disinfection. At two locations, NSF 60-certified sodium silicate is used for aesthetic purposes to sequester dissolved iron and manganese. In total, Water Services operates and maintains 31 facilities for water: sources, supply, treatment, storage or transfer.

The replacement cost of the entire system (excluding Gazer Mooney Subdivision Distribution System) is estimated to be $541.5 million or approximately $4,400 per capita. The majority of Guelph Drinking Water System operations are funded directly from the sale of water, with some additional funding through government grant programs. From Jan. 01 to Dec. 31 of 2012, a total of 16,560,328 cubic metres (16.6 billion litres) of water was treated and pumped to the system. The average daily water demand was 45,247 cubic metres (45.2 million litres). The highest daily use of water occurred on July 12, when 58,764 cubic metres (58.8 million litres) of water was pumped. The minimum day production of water was 31,536 cubic metres (31.5 million litres) and occurred on Dec. 25, 2012. From Jan. 1, 2012 to Dec. 31, 2012, all regulatory microbiological and chemical quality samples were taken by certified operators and tests performed by accredited, licensed laboratories on water samples collected throughout the drinking water system. These tests include both regulatory and operational testing – in most cases only regulatory reporting is included in this report. In all cases, the drinking water supplied to all customers was confirmed safe and the water was of higher quality than all Ontario and Canadian health-related guidelines. The Guelph Drinking Water System is defined as a large residential system operated under the regulatory requirements of the Safe Drinking Water Act and the Ontario Water Resources Act (accessed at http://www.e-laws.gov.on.ca). The Guelph Drinking Water System operated under Municipal Drinking Water Licence (MDWL) 017-101 (issue numbers 3 and 5) and the Drinking Water Works Permit (DWWP) 017-201 (issue number 3). The MDWL and the DWWP describe system-specific requirements that are supplementary to provincial regulations and act as licenses for water supply and distribution operations. These documents outline specific conditions and requirements regarding operation, maintenance and upgrades that are required by the system and are considered regulatory in nature. These documents are available by request for viewing at 29 Waterworks Place, Guelph.

Gazer Mooney Subdivision Distribution System The Gazer Mooney Subdivision Distribution System is a Class 1 Distribution Subsystem that serves approximately 200 people, and is owned by the Township of Guelph/Eramosa. The system is operated by Water Services by a legal agreement that was last signed by representatives of the City of Guelph and the Township of Guelph/Eramosa on July 30, 2009. All of the water for the Gazer Mooney Subdivision Distribution System is supplied from the Guelph Drinking Water System. All water is treated to provincial standards in the Guelph Drinking Water System and no further treatment chemicals are added to the Gazer Mooney Subdivision Distribution System. All new distribution infrastructure components meet NSF 61 requirements or approved equivalents and are installed and maintained in accordance with approved industry standards. The system is fully metered. The Gazer Mooney Subdivision Distribution System is comprised of the following infrastructure:

o approximately two kilometres of buried watermain with a diameter < 900 mm; o approximately 6 watermain valves; o approximately 6 fire hydrants; and o approximately 72 water services and water meters.

The cost of construction of the Gazer Mooney Subdivision Distribution System was listed as $197,933 in 1980. The Gazer Mooney Subdivision Distribution System is considered a small residential system and is operated under the regulatory requirements of the Safe Drinking Water Act and the Ontario Water Resources Act which may be found at http://www.e-laws.gov.on.ca. The Gazer Mooney Subdivision Distribution System operated under Municipal Drinking Water Licence No. 104-103 (issue number 1), and Drinking Water Works Permit No. 104-203 (issue number 1). These documents are available by request for viewing at 29 Waterworks Place, Guelph and at Township of Guelph/Eramosa, 8348 Wellington Rd. 124, Rockwood.

Summary Water Services Report

a) Incidents of Regulatory Non-Compliance This section describes all incidents of non-compliance (excluding those defined as “Adverse Water Quality Incidents” (AWQI) defined and reported in section b) of this report). AWQI’s are required to be reported to the Ministry of the Environment (MOE) with respect to the following Acts and related regulations: Ontario Water Resources Act (OWRA), Safe Drinking Water Act (SDWA), and the Environmental Protection Act (EPA), and Water Services’ Municipal Drinking Water Licences (MDWL) and Drinking Water Works Permits (DWWP). Guelph Drinking Water System There was one incident of non-compliance associated with the Guelph Drinking Water System in 2012 (Jan. 01 to Dec. 31). − On June 11, 2012, a UV treatment failure related to maintenance occurred and was off-line for 6 minutes.

Back-up systems functioned normally and chlorine disinfection was not affected. Assessment of Compliance The most recent assessment of compliance for the Guelph Drinking Water system as determined by the MOE during the 2012 Annual Inspection (for the period of Jun. 2011 to July 2012) resulted in an assessment score of 96.4 per cent (compliance), which included minor administrative non-compliance.

Gazer Mooney Subdivision Distribution System There were no incidents of non-compliance associated with the Gazer Mooney Subdivision Distribution System in 2012 (Jan. 01 to Dec. 31). Assessment of Compliance The most recent assessment of compliance for the Gazer Mooney Subdivision Distribution System as determined by the MOE during the 2012 Annual Inspection (for the period of Jun. 2011 to July 2012) resulted in an assessment score of 100 per cent (compliance). b) Incidents of Adverse Drinking-Water Tests This section describes all “Adverse Water Quality Incidents” (AWQI). This term refers to any unusual test result from treated water that does not meet a provincial water quality standard or situation where disinfection of the water may be compromised. An adverse water quality incident indicates that on at least one occasion, a water quality standard was not met. The process of water quality sampling and testing can result in false positive results for contaminants; these results can be caused by contaminated sampling containers and equipment, sampling technique, sample handling and transportation, and sample analysis. In almost all cases, mandatory follow-up sampling and analysis confirms that contaminants are not present in the water provided to customers.

c) Deviations from Critical Control Point (CCP) Limits and Response Actions This section describes any deviation from essential steps or points in the drinking water system at which control can be applied to prevent or eliminate a drinking water hazard or to reduce it to an acceptable level. These essential steps or points in the system are known as critical control points (CCP). The CCPs are used to identify control measures that are in place to address hazards and hazardous events. These CCPs are in part stipulated by regulation and in part derived through risk assessment of the Drinking Water System. Water Services’ Critical Control Points include:

- primary disinfection, - secondary disinfection, and - backflow prevention.

Additional information (e.g. critical control limits and response actions) is included in Appendix “A” in the “Summary of Critical Control Points and Critical Control Limits”. Deviations from the CCPs are reported to both the Owners and Top Management, and are summarized in the tables included in section b) of this report. There were no confirmed deviations from CCP Limits in 2012.

d) The Efficacy of the Risk Assessment Process This section confirms the occurrence of reviews of the risk assessment process to determine the effectiveness of the process in identifying and appropriately assessing the risk of hazardous events and hazards, and in identifying the appropriate control measures, critical control points (CCPs) and related critical control limits (CCLs). The thirty-six month risk assessment described in “QMS 08 Risk Assessment Outcomes” was conducted by Water Services’ Continuous Improvement Team Members on Feb. 15, 2012, subsequently approved at a Management Review Meeting on Feb. 22, 2012 and presented in Table 3 (in summary format) within this report.

Items in the "Effective Risk Management" section of the table with GREEN highlights indicate that Water Services has determined there are sufficient control measures to adequately control the risks. Items highlighted in YELLOW and RED indicate risk areas that are not sufficiently addressed through existing control measures, and require additional work.

+ - Improvement being made e) Internal and Third-Party Audit Results This section describes any of the audit outcomes identified to date that require follow-up actions. Internal auditing and third-party auditing is performed to fulfill the mandatory requirements of the Drinking Water Quality Management Standard (DWQMS). The internal audit is completed using internal staff. The

purpose of audits is to evaluate the level of conformance of Water Services to the DWQMS. Audits identify both conformance and non-conformance with the Standard as well as opportunities for improvement. The 2012 internal process audits were completed on Jun. 18 – 29 and Sep. 5 – 11, 2012. Internal audit findings identified are related to improving the control of documents and records (QMS 05) and ensuring the regular review of procedures by staff (QMS 10 and QMS 12). Third-party external on-site audits have not yet been completed, but are anticipated in 2013. f) Results of Emergency Response Testing Emergency response testing is regularly completed as a component covered by the Water Services’ Quality Management System (QMS) to ensure that Water Services maintains a reasonable readiness to deal with emergencies. The ability to deal with emergencies is critical in demonstrating that Water Services has taken a diligent approach to operating the Guelph Drinking Water System. Feedback from this testing is incorporated into the Water Services Emergency Plan and /or daily operations. Due to a decrease in staff in summer 2012, the fall emergency response tests have been deferred to 2013. Table 4 includes the Emergency Response Testing Schedule.

− 2012 Totalized Pumpages (Jan. 01 to Dec. 31) as per the Municipal Drinking Water Licence and Permits to Take Water;

− 2012 Instantaneous Flows (Jan. 01 to Dec. 31) as per Permit to Take Water requirements; − Water Production and Population; − 2012 (Jan. 01 to Dec. 31) Collector Flows; and − Other Operational Performance Data.

2012 Totalized Pumpages and Instantaneous Flows (Jan. 01 to Dec. 31). The Safe Drinking Water Act and the Ontario Water Resources Act each require that operating authorities record and report both water takings as governed by Permits to Take Water, and water being supplied by the City of Guelph. Summaries of total water pumped, instantaneous flows and capacity (flows and volumes compared to rated capacities) by the City of Guelph from Jan. 01 to Dec. 31 can be found in Appendix “C” – Total Water Pumped and Instantaneous Flows. 2012 Totalized Pumpages (Jan. 01 to Dec. 31). Figure 3 below depicts the water pumpage rate in cubic metres per day (m3/day) that is averaged each week.

Figure 3: 2012 Totalized Pumpages (Jan. 01 to Dec. 31)

Water Services processed 16,560,328 cubic metres (16.6 billion litres) of water to the distribution system in 2012 (Jan. 01 to Dec. 31). This represents 0.73 per cent less water being supplied to the distribution system in 2012 as

compared to the same time period in 2011 and 1.81 per cent more water than in 2010. The average daily water demand was 45,247 cubic metres (45.2 million litres). The maximum day production of water in 2012 was 58,764 cubic metres (58.8 million litres) and occurred on July 12, 2012. The minimum day production of water in the same time period was 31,536 cubic metres (31.5 million litres) and occurred on Dec. 25, 2012. Possible explanations for water use changes include: economic conditions (“an economic downturn”), seasonal variations (sufficient precipitation that is conducive to lower outside water use), and conservation programs outreach and education. Water Production vs. Water Consumption Figure 4: Guelph Water Production vs. Water Consumption vs. Population that follows depicts the maximum pumpages (peak water days), average daily water production, and average daily water consumption rates in cubic metres per day (m3/day) as compared against Guelph’s population.

Collector Flows The Arkell Spring Grounds Collectors (“Collectors”), one Guelph’s many water sources, consist of a gravity-fed under-drain system that collects shallow overburden groundwater. This system has been in use since the early 1900’s and can represent as much as 40 per cent of the total city-wide daily water production. When the output of this source is reduced, Water Services is required to make up the difference from other water supplies. Throughout the year, the production from this water supply varies from an approximate low of 4,000 cubic metres (4 million litres) up to an approximate high of 20,000 cubic metres (20 million litres) per day. The Collectors can also be used as a measurable index of the state of the environment (i.e. very dry to very wet as they respond to rainfall and other environmental conditions). The volume of water that the Collectors produce is one of the benchmarks used in the decision-making process to determine the appropriate level of outside water use for the City. Seasonally, between April 15th and November 15th, the City has a PTTW (permit to take water) that allows water to be pumped from the Eramosa River to a pond and trench-based “Recharge System”. In the Recharge System, the river water is filtered in-situ through the ground and approximately 50% of the flow is captured in the Glen Collector System. The productivity of the Collectors can also be used as a predictive tool. If the production volume from the Collectors is low, then it can be assumed that other water supplies would be needed to make up the difference. This may alter how regular maintenance is performed as well as the urgency with which repairs are made to supplies that unexpectedly go offline as they may be needed to supplement overall production for the City when the collector system is unable to produce a sufficient supply. The Collectors have produced 2,161,664 cubic metres (2.2 billion litres) of water in 2012 (Jan. 01 to Dec. 31). This represents 22.84 per cent less water as compared to the same time period in 2011 and 32.68 per cent less water than in 2010. Part of the discrepancy in the totalized volume comparison between 2012 and the two previous years can be attributed to the fact that the Recharge System is not being utilized in order to accommodate the Arkell OTP/AMP (Operational Testing Plan / Adaptive Management Plan) which is a condition of the Arkell Well Field PTTW (Permit to Take Water). Note: This information should not be used in isolation as a predictive tool. For a visual representation, please refer to Figure 5: 2012 Glen Collector Volumes (Jan. 01 to Dec. 31):

h) Raw and Treated Water Quality – Guelph Drinking Water System This section describes the water quality monitoring, both regulatory and operational, that has been collected in 2012 (Jan. 01 to Dec. 31). Water Quality Review – Guelph Drinking Water System Under the Safe Drinking Water Act (SDWA), municipalities are required to monitor both the raw and treated quality of the source water supplied. This monitoring is performed for both regulatory compliance and due diligence and is expected to identify any changes within the treated water as well as in the raw source waters.

Please note: All regulated chemical parameters where values above the lab’s MDL (minimum detection limit) have been detected in the City of Guelph’s treated water sources are underlined indicating a hyperlink to an Excel Workbook in Guelph’s EDMS (electronic document management system). Note: EDMS is available for internal use only. The workbook contains a definition of the parameter, an Excel worksheet for each treated source where the parameter has been detected with values for all sample results from Jan. 01, 2007 to Dec. 31, 2012. This database is used to closely track the instances of the identified chemical parameters and therefore provide time for planning / budgeting if treatment or an alternative supply is eventually required due to the presence of a given parameter. The database is updated quarterly. The following section summarizes daily Distribution free chlorine residual test results required by O. Reg. 170/03 Schedule 7-3 where “secondary disinfection” is provided for the period of Jan. 01 to Dec. 31, 2012. The Verney Tower sample point is used to represent the water quality provided by the Zone One distribution system pressure zone and the Speedvale Tower sample point represents the water quality provided by Zone Two for the purposes of the regulation. Please note that the City of Guelph takes additional “operational” daily Distribution samples and tests for free chlorine residual in order to better monitor the free residual in the Distribution System and respond accordingly. There was no instance of an adverse result in 2012 (Jan. 01 to Dec. 31): Table 7: O. Reg. 170/03 Schedule 7-3, City of Guelph - Distribution Manual Free Chlorine Residual Summary

While the values above satisfy the regulatory minimum regulatory requirements, Water Services performs many additional operational tests not listed in this report. Microparticulate and Laser Particle Counting Sampling As a part of the Guelph Drinking Water System’s Municipal Drinking Water Licence (MDWL), Guelph Water services is required to assess twice annually Arkell Well #1 and The Arkell Collector Systems which are both groundwater under the influence of surface water with effective in situ filtration (GUDI-WEF). The purpose of the assessment is to ensure that the sources continue to meet the GUDI-WEF source water characteristics as outlined by the MOE. Sampling was performed on these two water sources in the spring and fall of 2012. The sources continue to meet the GUDI-WEF source water characteristics. Treated Water Quality Statistics – O. Reg. 170/03 Schedule 6 - “Continuous Monitoring” Results Summary Water Services utilises over twenty regulatory and operational continuous monitoring devices to measure water quality. Each regulatory device has controls associated with it such that in the event that the device detects that a measured value is outside the acceptable parameters for that location, the device causes an alarm to be sent to an operator for immediate response (24 hours per day seven days per week) and either automatically shuts down the station or activates a second alarm for immediate operator response. Both the minimum allowable levels (if applicable) and the target values for Water Services regulatory continuous monitoring devices are listed below. The target values represent a safety margin to help ensure that regulatory requirements are satisfied at all times. Please note that with the exception of the values reported in the AWQI section of this report (Section B), if applicable, continuous monitoring values all fell within acceptable regulatory standards in 2012 (Jan.01 to Dec. 31).

Treated Water Quality Statistics – O. Reg. 170/03 Schedule 13-6 and 13-7, “Three Month” Sampling Results Summary In 2012, all operational Treated Sources were sampled and analyzed for Schedule 13-6 and 13-7 parameters as per O. Reg. 170/03. Regulation 170/03, Schedule 13-6 requires a minimum of one distribution sample taken from the Distribution System where THM’s (trihalomethanes) are most likely to develop (points with high retention times). Water Services uses Speedvale Tower and Clair Tower for this purpose in the Guelph Drinking Water System. The Maximum Allowable Concentration (MAC) for THM’s is 0.1 mg/L. However, for this parameter the MAC uses a running annual average of quarterly samples. The results of the running average value for THM’s for all related Distribution System samples in 2012 are below the ½ MAC (half of the maximum allowable concentration). All operational Treated Sources were sampled and analyzed for Nitrates and Nitrites as per Regulation 170/03, Schedule 13-7. The results for 2012 were under the ½ MAC. Raw sampling results are also shown in Table 12 (ODWQS do not apply to these values).

Treated Water Quality Statistics – O. Reg. 170/03 Schedule 23 Results Summary If sampling for a particular schedule’s parameters (e.g. Schedule 23 and 24) did not occur within the calendar year of the report, then the most recent values are required to be included in the report for reference. In 2010, all “Treated Sources” were sampled and analyzed for Schedule 23 parameters as per O. Reg. 170/03. All of the City of Guelph’s treated ground water sources are on a three year sampling schedule. F.M. Woods’ Station is the exception and is sampled on the annual surface water schedule due to the fact that three of the eight sources that supply F.M. Woods’ are GUDI-WEF sources (the Carter Well field, Arkell 1 and the Arkell Glen Collectors). The results of the Schedule 23 inorganic parameter analysis in 2010 were all under the ½ MAC (half of the maximum allowable concentration) and the majority were under the laboratory’s MDL (minimum detection level). Please refer to the section entitled “O. Reg. 170/03 Schedule 23 Results Summary” included in Appendix “B” for more information. The next scheduled “Three Year” Schedule 23 sampling event takes place in the third quarter of 2013. The results of the Annual Schedule 23 inorganic parameter analysis in 2012 for F.M. Woods’ Station were all under the ½ MAC (half of the maximum allowable concentration) and the majority were under the laboratory’s MDL (minimum detection level).

Treated Water Quality Statistics – O. Reg. 170/03 Schedule 24 Results Summary If sampling for a particular schedule’s parameters (e.g. Schedule 23 and 24) did not occur within the calendar year of the report, then the most recent values are required to be included in the report for reference. In 2010, all “Treated Sources” were sampled and analyzed for Schedule 24 parameters as per O. Reg. 170/03. All of the City of Guelph’s treated ground water sources are on a three year sampling schedule. F.M. Woods’ Station is the exception and is sampled on the annual surface water schedule due to the fact that three of the eight sources that supply F.M. Woods’ are GUDI-WEF sources (the Carter Well field, Arkell 1 and the Glen Collectors). The results of the Schedule 24 organic parameter analysis in 2010 were all under the ½ MAC (half of the maximum allowable concentration) and the majority were under the laboratory’s MDL (minimum detection level). Please refer to the section entitled “O. Reg. 170/03 Schedule 24 Results Summary” included in Appendix “B” for more information. It should be noted that values for TCE (trichloroethylene) at Membro and Emma have on occasion, crested the ½ MAC value of 0.0025 mg/L and as a result Water Services has moved to an “Increased Frequency Sampling Plan” as required by Regulation 170/03 - 13-5 which requires that sampling for this parameter be sampled every “three months” until two consecutive samples receive results below the ½ MAC value. As a precautionary measure, Water Services samples both raw and treated on a monthly schedule at Membro and Water. All other sources (raw and treated are sampled annually (minimally) for VOC’s (Volatile Organic Carbon) through a “Guelph VOC Scan” in

order to better track parameters such as TCE via more data. Currently, TCE is above the MDL but below the ½ MAC at Membro, Water Street, Park and Paisley* POE. *The TCE at Paisley POE can be attributed to Emma, Membro, Water Street and Park via the Paisley Reservoir low zone fill line as VOC analysis from 2007 to the present on Paisley raw water show values below the lab’s MDL (minimum detection level) for all parameters. The next scheduled “Three Year” Schedule 24 sampling event takes place in the third quarter of 2013. The results of the Annual Schedule 24 organic parameter analysis in 2012 for F.M. Woods’ Station were all under the ½ MAC (half of the maximum allowable concentration) and the laboratory’s MDL (minimum detection level).

Treated Water Quality Statistics – O. Reg. 170/03 Schedule 13-8 and 13-9, “Five Year” Sampling Results Summary If sampling for a particular schedule’s parameters (e.g. Schedule 23 and 24) did not occur within the calendar year of the report, then the most recent values are required to be included in the report for reference. The last occurrence of the scheduled “Five Year” sampling event was in 2009. Fluoride is sampled on this schedule. In 2009, Fluoride (naturally present) was detected at all treated sources; the analytical results were all under the ½ MAC (half of the maximum allowable concentration). The values in Table 16 reflect the 2009, Schedule 13-9 sampling regime. Sodium, however, is sampled on a more frequent basis (annually) due to the fact that at every treated source with the exception of F.M. Woods (currently), sodium levels are above the lower reportable limit of 20 mg/L. The increased frequency of sampling provides more data in order to better establish sodium value trends. Sodium results for 2012 can be referenced in “Table 17: City of Guelph General Chemistry Selected Results Summary”. This data is provided to the Wellington-Dufferin-Guelph Public Health Unit. The next scheduled “Five Year” Schedule 13-8 and 13-9 sampling event takes place in the second quarter of 2014. Table 16: O.

Water Quality Review - Gazer Mooney Subdivision Distribution System Under the Safe Drinking Water Act (SDWA), municipalities are required to monitor both the raw and treated quality of the source water supplied. This monitoring is performed for both regulatory compliance and due diligence and is expected to identify any changes within the treated water as well as in the raw source waters. Please note: All regulated chemical parameters where values above the lab’s MDL (minimum detection limit) have been detected in the City of Guelph’s treated water sources are underlined indicating a hyperlink to an Excel Workbook in EDMS (electronic data management system). The workbook contains a definition of the parameter, a worksheet for each treated source where the parameter has been detected with values and a bar graph that contain all sample results from Jan. 01, 2007 to Dec. 31, 2012. This database is used to closely track the instances of the identified chemical parameters and therefore provide time for planning /budgeting if treatment or an alternative supply is eventually required due to a given parameter. The database is updated quarterly. The following section summarizes daily Distribution free chlorine residual test results required by O. Reg. 170/03 Schedule 7-2 for the period of Jan. 01 to Dec. 31, 2012. There was no instance of an adverse result in 2012 between Jan. 01 and Dec. 31:

− Water Conservation: o Efficient Home Visit (EHV) Pilot Program completed on Mar. 31, 2012. Throughout the pilot phase

of the program 177 households received a customized home water and energy audit, and select water and energy retrofits, from a trained audit advisor. Collectively, these visits resulted in water savings of 2,900 m3/year (2.9 million litres/year), electricity savings of 35,507 kWh/year and natural gas savings of 9,657 m3/year. These savings translate into an average savings of $77/year in utility savings per participant household.

o City of Guelph Water Services received the first ever Canada Water Week Award of Recognition for outstanding efforts in support of Canada Water Week on Mar. 27, 2012. The award recognizes communities that excel at building local energy, support and awareness on water issues during the week. In total, over 10 local water-based events offered in Guelph during Canada Water Week (Mar. 19 -25, 2012) through collaboration with local school boards, industry associations and environmental interest groups.

o City of Guelph Residential Greywater Field Test completed in Apr. 2012. Through field test 25 greywater reuse systems were installed in new and existing local homes with detailed performance monitoring and social feedback completed by City staff and project partners to assess the feasibility of technologies tested. Field Test final report available for reference at www.guelph.ca/greywater.

o The City Outside Water Use Program (OWUP) implemented “Level 1 Yellow” on April 25, 2012 in alignment with local watershed conditions via the Ontario Low Water Response Plan. OWUP level increased to “Level 2 Red” on July 18, 2012 due to continued drought conditions, which implemented ban on outdoor lawn watering and further restrictions on other outside water use activities. Program level was later reduced back to “Level O Blue” on November 1, 2012 due to recovery of watershed surface water conditions, in accordance with level 0 low water declaration of Grand River Low Water Response Committee.

o Detailed engineering design was ongoing throughout 2012 for integration of water reuse and rainwater harvesting within Guelph Transit’s bus wash process. These demand substitution processes is anticipated to reduce water and wash chemical needs per bus washed by 40% with system installation planned for early 2013. Project made possible through grant received from Province of Ontario’s Showcasing Water Innovation Program.

o 2012 Leak Detection Program initiated on October 4, 2012. The program included establishment of City’s first District Metered Area (DMA) located within the University Village Neighbourhood on Stone Rd W as well as the sonic evaluation of 100 km of metallic watermain within “the Ward” neighbourhood as well as all residential and industrial areas north of Speedvale Avenue. In total, 3 watermain breaks and 4 hydrant leaks were identified as a result of the program, possessing a total daily volume 470 m3/day (470,000 litres/day).

o Continued operation and optimization of existing Conservation programs (e.g. Residential Rebate Programs, Blue Built Home, ICI Capacity Buyback Program, etc.)

Source Water Protection Plan This section includes summaries on Guelph’s Source Protection Projects, the Development of Source Protection Policy Choices, and Ontario Drinking Water Stewardship Program Grant. Guelph’s Source Protection Projects On Jun. 18, 2012, staff submitted a report on Source Water Protection Policies for consideration by the LESP Committee. The scope of the protection policies includes conditions identified as significant threats, spill prevention, contingency or emergency response plans, transport pathways, and transition policies. Additionally, there is a proposed draft policy for fuel storage and handling as well as the assignment of Risk Management Official/Inspector roles for implementation of the source protection process. The LESP Committee has completed consultation to allow for opportunities to provide input and comments on the Draft Grand River Source Protection Plan, and this Draft Plan includes policies for the City of Guelph. The Draft Protection Plan was released by the Source Protection Committee for public review and comment on Aug 20, 2012 through Oct 3, 2012. In response to the comments received on the Draft Source Water Protection Plan the Source Protection Committee has made revisions and updates to the Plan and released the “Proposed Source Protection Plan” for the Grand River watershed for public comment until Wednesday, Jan. 16, 2013. Up-to-date information on the City’s Source Protection Program has been available to the public on the City’s website at: http://www.guelph.ca/living.cfm?subCatID=2234&smocid=2807. Ontario Drinking Water Stewardship Program Grant The provincial government created the Ontario Drinking Water Stewardship Program (ODWSP). It provided grants to help pay for a variety of projects that protect municipal water supplies from contamination. Water Services received ODWSP grant funding for its Fuel Station Upgrade project. Water Services hired the consulting services of Gamsby & Mannerow (under contract #11-077) and the contractor services of Drexler Construction Ltd. (under contract #11-144) to assist in the achievement of the Fuel Station Upgrade project objectives. The fuel station upgrade was completed Jan. 2012 and the final report as required by the “Grant Funding Agreement under the 2010-2011 Ontario Drinking Water Stewardship Program – Special Projects Early Response (SPER1011-07)” was submitted to the Ontario Ministry of the Environment Source Protection Programs Branch on Mar. 22, 2012. Arkell Afforestation Project The Arkell Spring Grounds cover an area of 804 acres. The area is comprised of old and new forested areas, which makes is necessary for monitoring, maintenance and new planting plans. This objective of the Arkell Afforestation Project is to manage past plantings and prevent losses while monitoring general forest health. Delicate forest stands require continued maintenance and observation to ensure the prevention of any unnecessary and undesired losses. Since 2007, the Community Environmental Leadership Program (CELP, on volunteer basis) has planted 11,500 trees on 15 acres and Bartram Woodlands (on-site contractor) has planted 13,300 trees on another 15 acres.

The many benefits of the Arkell Afforestation Project include the creation of a diverse and functioning forest cover, maintenance and re-generation of older forested areas on the property, protection and recharge of underground aquifers, prevention of undesirable surface water runoff and flooding into local waterways, and regulation of the flow of water. The characteristically strong organic matter component of soils within a forest allows for added infiltration and precipitation to recharge the underlying aquifer. The filtration ability of a forest system results in an additional obstacle to filter water. This multiple barrier approach results in the highest possible quality of water to supply Guelph’s drinking water system. Forest systems also extend the longevity of the existing snow pack by stabilizing the temperature of the ground and limiting the impact of the sun. This ensures water resources are re-absorbed into the underlying aquifer where they are needed rather than contributing to damaging runoff and flooding. Lead Reduction Plan This section provides a summary of the following two aspects of the Lead Reduction Plan (LRP)

− Regulatory Lead Sampling − Regulatory Lead Reduction Plan

More information on the “Lead Reduction Plan – Update Report” is included in Appendix “E”. Regulatory Lead Sampling Summary For the period of Jan. 1 to Mar. 20, 2012, sampling was conducted in compliance with reduced sampling requirements as per Schedule D of Guelph’s Municipal Drinking Water Licence. The application for full regulatory relief from the sampling requirements of Schedule 15.1, and a post-implementation monitoring program as part of the City of Guelph’s Lead Reduction Plan (LRP) (in lieu of a Corrosion Control Plan) were submitted in Apr. 2011 and were subsequently fully approved on Mar. 21, 2012. All sampling conducted from Mar. 21 to Dec. 31, 2012 was conducted in compliance with the LRP and will continue to be, in accordance with the approved regulatory relief. The next table presents summary results for regulatory lead sampling in the Guelph Drinking Water System:

Regulatory Lead Reduction Plan For the period of Jan. 1 to Dec. 31, 2012, sampling and lead reduction programs were conducted in compliance with the City of Guelph’s Lead Reduction Plan while application for relief was under review. The application for relief was fully approved on Mar. 21, 2012. The City of Guelph Lead Reduction Update Report for the Period of Jan. 1, 2011 to Dec. 31, 2012 is available online at guelph.ca/water under Publications. The Update Report provides a detailed summary of progress made to date as per the Lead Reduction Plan and post-implementation monitoring. Lead Sampling Lead sampling is conducted to identify the presence of lead service lines (LSL) and to monitor lead levels following a LSL replacement. For the period of Jan. 1 to Dec. 31, 2012, 426 Lead Verification samples were taken. Of these sample results, 7.3% were above 5 µg/L indicating presence of a lead service line. Of all verification samples, 5.4% also exceeded the ODWQS of 10 µg/L. Lead samples are collected before and after a LSL replacement has been undertaken. There were 136 resamples collected in order to monitor lead levels post-replacement. Based on sample results to date, regulatory compliance is expected at individual sites that have undergone a full LSL replacement or where there is no lead remaining in the service line.

Lead Service Line Replacements There were 68 Lead Service Line (LSL) replacements undertaken in the City between Jan. 1 to Dec. 31, 2012. These replacements include the following situations: i) Full LSL Replacement where both the City- and private-side of the LSL is replaced, ii) Partial LSL Replacement where only the City-side of the service is replaced and connected back to lead or a non-lead material on the private-side, and iii) Private LSL Replacement where the private-side of the service is replaced and the City-side is known to be copper. The next table presents a summary of all LSL replacements in the Guelph Drinking Water system for 2012.

Changes Affecting the Quality Management System (QMS) QMS 05 – The City’s Information Services is implementing The Ontario Municipal Records Management System (TOMRMS) to support its Records Retention and Destruction By-law. Under TOMRMS and the Records Retention and Destruction By-law, Water Services is required to ensure that its documents and records are properly retained for the appropriate times. QMS 07/08 – Following the review of QMS 08 Risk Assessment Outcome, Building Services staff responsible for the Backflow Prevention Program have suggested that the risk rating related to cross-connection contamination from inappropriately set-up temporary connections should be higher with a likelihood rating of 4 or 5, increasing the risk rating from 2 to 8 or 10. There is more to be done to control the risk, and as new control measures are implemented, the likelihood rating can be reduced. QMS 09 – Water Services is currently working through an organizational review. Acting Supervisor positions have been appointed temporarily, as required. l) Consumer Feedback The table below represents all customer calls received during office hours and after hours:

n) The Results of Infrastructure Review The review of infrastructure requirements is achieved by reviewing the needs of existing infrastructure and of new infrastructure requirements. This review is carried out for infrastructure needs of distribution and supply & facilities. Distribution Infrastructure Needs On a regular basis (at monthly meetings), Guelph’s Engineering and Water Services review the condition of supply and distribution infrastructure and review: inventory, age, CAPS (capital asset prioritization system), criticality, soil type and diameter. From this evaluation, Engineering and Water Services develop a list of priority projects that also considers the priorities of wastewater and road reconstruction projects so that these projects can share the costs of excavation and rehabilitation. The priority list is updated (with considerations included) and presented in Annual Operating Budget and the Tri-Annual Capital Budget processes. New linear infrastructure reviews are primarily driven by Engineering Services. Annual summaries of road reconstruction, sewer and watermain projects are identified annually on an infrastructure map that is released early spring each year. An Asset Update Report was prepared to develop a funding strategy and to rate sustainability for various infrastructure programs across the City. Water Services’ sustainability rating is A-. Supply & Facilities Infrastructure Needs In Nov. 2012, Water Services received consultant proposals for the update of the Water Supply Master Plan. It is anticipated that the Water Supply Master Plan will be updated in 2013. The Master Servicing Study is another infrastructure plan that is updated every five years and is used to identify new and replacement infrastructure priorities to include in the budgeting process. The development of a Facility Master Plan is also in progress, along with new initiatives related to property planning for expansions of facilities or to implement new facilities, as required. The Owner (Council & CAO) is updated regarding any deficiencies or gaps. Backflow Prevention Program Preservation of drinking water quality within Guelph’s infrastructure is supported by the City of Guelph’s Building Services and Guelph’s Backflow Prevention Regulations (“By-law”, Number (2008) – 18660). As per the By-law, “Backflow” means the flowing back of or reversal of the normal direction of flow of water. The By-law requires that no connections are made to the City’s water supply without the installation of a backflow prevention device to isolate premises, sources, and zones to prevent cross-connections in every building or structure where a City water supply or other potable water supply exists. On a regular basis, Building Services provides the following “Backflow Report” included in the table below that tracks the number of letters sent out regarding annual testing and re-surveying requirements of the By-law.

The City of Guelph has a total of 2,535 facilities (2,516 active and 19 inactive facilities) that have a total of 5,771 backflow prevention devices installed. Of the total facilities, 1,719 are facilities with premise isolation and 797 are facilities without premise isolation (e.g. residential irrigation systems, plaza facility – plaza owner has premise isolation). New buildings from Jan. 01 to Dec. 31: 22 with premise and 41 without premise isolation.

Hyperlinks to the e-mail messages summarizing improvement actions are included below.

Table 30: Improvement Actions Summary OFI # Suggestion Title Improvement Action Description

12-01 Monthly Nitrate Sampling @ Carter’s

Increased frequency from 1:3mos to monthly to better determine any seasonal variations in nitrate levels in the source water at Carter’s.

12-02 Changes to Monthly VOC Sampling @ Emma and Membro

Changing monthly VOC sampling from monthly to 1:4 weeks at Emma and Membro and taking into account consistency in well operations between samples in order to better compare.

12-03 Scheduling Calibrations / Verifications

Annual verification / calibration of instrumentation at various sites will be scheduled by site and not by equipment type, saving considerable travel time.

12-04 Paisley and Water Screen Improvements

Updates to Paisley and Water Street Screens were made to better access pump controls and alarm setpoints.

12-05 Changes to Regulatory and Operational Sampling Programs

As previously communicated re: Emma and Membro (1:4weeks). Operational / Regulatory raw and treated sampling at all other sites are changing from 3- to 9-month schedules. Removed VOC sampling at sites that never had TCE issues, and added distribution locations to better study TCE. Added QAQC Sampling. All forms and schedules updated.

12-06 Clarification re: Water Quality Monitoring

Clarified that VOC Sampling changes from 3- to 9-month schedules (as described above) does not include F.M. Woods since it is a GUDI-WEF source and requires annual sampling.

12-07 Documentation & Compliance Improvement items on documentation requirements for improved compliance were summarized and include: documenting presence, who is Lead Hand, and proper completion of chains of custody for drinking water samples.

12-08 Water Conservation Program Online Progress Reporting Tool

A new web interface for the City’s Water Conservation Program including a new online public progress report for the program and interactive home-based water efficiency tour.

12-09 Improvements to Well soft start parameters

Well soft start parameters were changed to allow for automatic resets of faults (such as when the power goes out).

12-10 Workflow Software re: SOPs to SCADA in Step-by-Step

Bring SOP’s and other rarely used procedures to SCADA computer screens in a step by step guide format.

12-11 Operational Adjustments with Deterioration of Sodium Hypochlorite

Deteriorating strength of the existing stock of sodium hypochlorite at sites taking longer than normal to use the supply has required operational adjustments to ensure that the dosing for primary disinfection is correct.

12-12 Response to Intrusion Alarms Instructions for responding to after-hours intrusion alarms at critical sites, at less critical sites and remote sites.

12-13 Park Elevated Chlorine Residual Incident

The chlorine residual in Park’s contact chamber was elevated at 7.46 mg/L. Sodium hypochlorite siphoning appeared to occur through the peristaltic pump. In response, the tube was replaced, discharge line was recharged and the siphon eliminated. The injector check valve on the discharge line was cleaned and replaced. The pressure sustaining valve was cleaned and a pressure gauge added so that back pressure can be monitored on the discharge line.

OFI # Suggestion Title Improvement Action Description

12-14 Security at F.M. Woods Key pads for arming or disarming areas of Water Services are grouped to minimize nuisance intrusion alarms. This makes it easier on operators to investigate any alarms.

12-15 Updates to Chlorine & Turbidity Setpoints screen in the Teledac Menu

Chlorine & Turbidity Setpoints screen under the Teledac Menu were updated to make it more clear for setpoint values which now have pop-up windows on their respective station screens. Woods reservoir level graphics are also now animated on the Woods Reservoir screen.

12-16 Arkell Glen Collector Improvement

Uncharacteristic microbiological counts in the Glen Collector source water indicated an infiltration source within the Collector System. In response, the sampling program was increased to daily, and as a precaution the collectors were diverted until Manhole 37x has been repaired. Once repaired, the samples that followed confirmed that the source of the microbiological count was mitigated.

12-17 Leak Detection Program – District Metered Area Implementation at Stone Road W.

The Leak Detection Program – District Metered Area was implemented in the area located between Stone Road West and College Road West to monitor water demand and potential recoverable water leakage in the area. More information to follow.

Appendix “C” – Total Water Pumped and Instantaneous Flows Note on Capacity: Capacity is calculated by comparing the average pumped or flow value against the MDWL allowable volume or PTTW flow. Capacity is representative of the conditions of pumping for that year which may be influenced by other testing programs, maintenance or special operational conditions. Additionally, the actual capacity of the source may not be achievable with current infrastructure. Optimization efforts are included as a component of the Water Supply Master Plan with the intent to match the actual capacity of the water source with the appropriate infrastructure.

Appendix “D” – Water Conservation & Efficiency Program – 2012 Annual Progress Report Background: The City of Guelph strives to be a leader in water conservation and efficiency. As one of Canada’s largest communities reliant solely on a finite groundwater source, our ability to reclaim precious water capacity through conservation initiatives offers numerous benefits. Furthermore, as the assimilative capacity of the Speed River to accept increasing amounts of treated wastewater effluent is limited, the ability to reduce the volume of wastewater requiring treatment offers ecological benefits to the Grand River Watershed as well as financial benefits to Guelph. Water and wastewater servicing capacity reclaimed through water conservation is the most cost-effective and immediately available source of new water supply and wastewater treatment capacity. Since 1999, when Council approved the first Water Conservation and Efficiency Strategy, 4,820 m3/day of average day water/wastewater capacity has been saved, allowing the City to delay the need for approximately $24 million in additional water and wastewater infrastructure. In addition, since 2001 when the City’s Outside Water Use Program was first implemented, the community has reduced our annual peak day water use (i.e. the highest daily demand for water each year), by over 11,800 m3/day, thus reducing infrastructure required to meet peak demand which is experienced on only a few days each year. Furthermore, water conservation has led to a reduction in the amount of electricity and water treatment chemicals used to treat and convey water and wastewater. This results in an annual operational savings of approximately $315,000 per year, creating a significant financial benefit to our rate payers. As a result of such efforts, the City’s water and wastewater rates remain much lower (within the 50% percentile) than that of many comparable Ontario and local municipalities. In 2006 City Council endorsed the Water Supply Master Plan (WSMP). This detailed Master Plan evaluated the water demand associated with projected growth over a 50 year planning horizon, as well as alternative sources of new water supply. Water conservation was identified as the most cost-effective and immediately available source of new water supply and was ranked as the #1 priority. The WSMP included three reduction targets based on 2006 daily water production volumes:

• Reduction of 10% (5,300 m3/day) in average day water use by 2010; • Reduction of 15% (7,950 m3/day) in average day water use by 2017; and • Reduction of 20% (10,600 m3/day) in average day water use by 2025

Both the 2007 Community Energy Initiative and the 2007 Council Strategic Plan set sustainability performance goals of using “less water and energy per capita than any comparable Canadian city.” These goals continue to guide our current water conservation activities and bring greater emphasis to the relationship between water supply and energy demand. To achieve these targets staff initiated the Water Conservation and Efficiency Strategy (WCES) Update in February of 2008. This award winning 10-year strategy was endorsed by Council in May 2009 and identifies the preferred program, policy and resource recommendations to achieve a further reduction of 8,773 m3/day by 2019, as well as

to achieve the aggressive reduction targets of the Water Supply Master Plan, Water and Wastewater Master Servicing Study, Wastewater Treatment Master Plan, Community Energy Initiative and Council's Strategic Plan. 2012 Progress Overview The following sections provide an overview of Water Conservation and Efficiency Program activities undertaken in 2012. For more information on individual programs or initiatives please visit: www.guelph.ca/ourstoconserve.

1. Leak Detection Program The City’s leak detection program aims to reduce the amount of water lost between the time of production

and end delivery to customers. In 2012 the program included the evaluation of 100 km of the City’s linear water main infrastructure through use of sounding and correlation technologies. In total 3 watermain breaks and 4 hydrant based leaks were identified through the study with approximately 470 m3/day in water production capacity anticipated to be reclaimed as a result of remediation of the leakage located.

The 2012 Leak Detection Program also saw the introduction of City’s first district metered area (DMA)

within the Woodland Glen neighbourhood located on Stone Rd West. Through this endeavour a permanent underground flow meter and chamber were installed as well as isolation of this area of water distribution system undertaken, so to allow water use in this area to be monitored through a single metered watermain. This approach to leak detection will allow staff to define the normal profile of efficient water delivery for the area as well as provide a baseline to evaluate future demands against so to assess the occurrence of potential leakage within the area. Through resources graciously provided via the Province of Ontario’s Showcasing Water Innovation Program, Guelph Water Services is currently working to design and implement a number of additional DMAs within 2013, with all field flow information to be transmitted back to the City’s SCADA operational system. Through this initiative operational control limits will be set for flow information being captured by SCADA for each area and Water Services staff will be alerted to potential leakage within monitored DMAs based on changes in flow profiles. This approach to water loss management is anticipated to allow for the proactive response to distribution system leaks and retention of water savings already reclaimed from prior leakage restoration.

2. Residential Water Conservation Rebate Programs

Within 2012 a total number of 3126 rebate applications were processed via the City’s residential rebate programs. The majority of rebates offered continue to be based in the City’s Royal Flush Toilet Rebate and Smart Wash Clothes Washer Rebate Programs with a moderate amount through the Home Humidifier Rebate Program and Greywater Reuse Rebate Program. In total, approximately 354.6 m3/day of reclaimed water savings is anticipated as a result of residential rebate program participation in 2012. For more information on the City’s Water Conservation Rebate Programs please visit www.guelph.ca/rebates.

3. ICI Water Capacity Buyback Program Since introduction of the ICI Water Capacity Buyback Program in 2007 the City has reclaimed over 1,100 m3 per day in water/wastewater servicing capacity while assisting local business to reduce their environmental footprint and ongoing operational costs. This program offers financial assistance to local business for the completion of detailed water efficiency process audits and incentives towards capital

Page 60 of 69

retrofits which reduce water demand. To date many of the City’s top water users have participated in this program, but participation amongst business possessing a smaller water use footprint has been limited due to investment required to undertake process audits and uncertainties of financial efficiencies to be realized as result of participation. In recognition of these challenges, Water Services’ ICI Water Efficiency Specialist continued work in 2012 to engage and support members of the Guelph business community. This resource offered engineering services to the local business community in conducting detailed preliminary water use audits with the intent of realizing potential efficiencies and limiting financial risk to business in participating in the program.

Through use of this resource a total of 9 detailed facility audits were completed in 2012. In addition, water efficiency capital retrofits were also implemented by Guelph General Hospital, Blount Canada and Polycon Industries stemming from previous audit recommendations, accounting for 248 m3/day in observed water use reduction.

4. Civic Facility Water Efficiency Upgrades

With the objective of leading by example through the City’s own operations, water efficiency retrofits of City owned facilities continued throughout 2012. These retrofits included domestic retrofits at the Main Branch Library as well as the second phase of water efficiency improvements to City owned sports field irrigation systems, focused on the introduction of enhanced field monitoring, automation and control technologies. These technologies will help qualify water needs based site specific conditions (such as soil moisture and evapotranspiration) as well as provide the ability to proactively identify system issues through automated prompts and alarms to system operators. Upon full implementation of these upgrades, it is anticipated that water demand associated with sports field irrigation will be reduced by 30% while maintaining the desired turf standards of sports field users. Beyond Civic facility retrofits completed, detailed engineering design for the integration of water reuse and rainwater harvesting processes at the Guelph Transit Bus Wash facility continued throughout 2012. This initiative anticipates water and wash chemical savings of $6,700 per year based on 2013 water and wastewater user rates. Construction of this project is anticipated for completion within the fall of 2013 with approximately $89,000 in funding provided through the Ministry of the Environment’s Showcasing Water Innovation Funding Program for detailed design and implementation of the project.

5. Efficient Home Visit and Retrofit Pilot Program On October 1, 2011 the Efficient Home Visit and Retrofit Pilot Program was introduced by the City of Guelph in partnership with Guelph Hydro, Union Gas and Guelph Environmental Leadership. Through this pilot program, all homeowners in the Hanlon Creek Neighbourhood (HCN) were eligible to receive a complementary 45-minute in-home water and energy audit conducted by a trained home advisor. The aim of the program was to identify potential water and energy efficiencies in each home, carry out a number of retrofits, and provide personalized information to homeowners regarding local resources and rebates/incentives that are available to assist in achieving conservation savings and reducing utility bills.

In total, 177 Efficient Home Visits were conducted over a 6-month period between October 1, 2011 to March 31, 2012. . Of the 177 audit visits actual savings ranged from $0/year to $499 per household across all participants, with $373/year per household being the highest savings in the targeted neighbourhood (HCN). This pilot program represents the implementation of the final programming recommendation of the Council-approved 2009 Water Conservation and Efficiency Strategy Update. Staff reported to the Planning & Building, Engineering and Environment Committee in the October 26, 2012 report following completion of the pilot program, and formed recommendations regarding the future of the program for Council’s consideration. For more information on the Efficient Home Visit and Retrofit Pilot Program please visit: www.guelphgig.ca.

6. Blue Built Home Water Efficiency Standards and Rebate Program

Endorsed by City Council in November 2010, the Blue Built Home Water Efficiency Standards and Rebate Program is a voluntary construction standard designed to outperform the plumbing and water-using fixture requirements of the Ontario Building Code. This certification program for new homes uses an approved set of high-quality home fixtures and appliances designed and third-party tested to save water and reduce water and wastewater utility bills by 24 to 54 per cent. Blue Built Homes are certified according to three water efficiency standards - Bronze, Silver or Gold – and provides the home buyer with a one-time rebate on their investment. Since launch of the program, a total of 25 new homes have been Blue Built Home certified (23 Bronze, 2 Silver). Of these, 12 Blue Built Bronze homes were certified in 2012. The Blue Built Home standard has been featured as part of 3 local demonstration homes in partnership with local home builders including Reid’s Heritage Homes, Sloot Construction, and TerraView Homes. To evaluate the impact of this building standard water use datalogging is currently ongoing at each Blue Built Home through the use of radio read flexible axis water meters. To date, the evaluation of water use amongst Blue Built Home Bronze in the field have demonstrated an additional savings of 32.9 m3/year compared to that initially anticipated through design of the standard for a family of 3 persons (144 m3/year). Beyond initial success of the program, staff began review of the Blue Built Home Program in late 2012 with the objectives of improving the level of builder participation in the program as well as increasing the affordability and awareness of the program amongst those purchasing new homes. Feedback has been gathered from BBH homeowners and the BBH building partners through an internet survey and discussions. To gain feedback from the local home building community, a Notice of Intent to revise the standard was introduced in December 2012. In alignment with this notice, a summary report on the Program and online questionnaire were made available via the Blue Built Home webpage to seek feedback on proposed amendments to the standard and associated program resources. Further consultant on

revisions to the standard is anticipated for early 2013 with final notice of amendments of the standard anticipated for summer/fall of 2013. For more information on the Blue Built Home program please visit bluebuilthome.ca.

7. Residential Greywater Field Test The City’s Residential Greywater Field Test concluded in July 2012. This project aimed to evaluate the appropriateness of home based water reuse systems as a water conservation programming alternative through detailed field monitoring and research of social acceptance amongst homeowner participants. Since launch of the program in 2009 a total of 25 greywater systems have been installed. These systems collect water from showers and baths in home, treat the water collected and store the treated greywater water for later use in satisfying toilet flushing needs in the home. To date new and existing homes possessing a greywater reuse system have seen an 10.2% and 26.8% reduction in total household water demand, respectively. However, ongoing water quality results from homes possessing greywater systems did not demonstrated overall compliance with treated greywater guidelines, with overall system performance dependent on the homeowner’s diligence in completing necessary system maintenance requirements. In alignment with the City’s Federation of Canadian Municipalities Green Municipal Fund agreement for this project, staff and project partners published the final Guelph Residential Greywater Reuse Field Test report on June 29, 2012. This report is now available for public reference at www.guelph.ca/greywater.

8. Youth Education The City’s curriculum based, Grade 2 and Grade 8 in-class water conservation programming continues to be a popular resource for local educators in both the Upper Grand District School Board (UGDSB) and the Wellington Catholic District School Board (WCDSB), encompassing 43 interactive school presentations to 1173 students conducted in 2012. Overall since the inception of the program three years ago, the City has provided a total of 123 school presentations to over 3600 students through this water conservation educational initiative. Furthermore, in partnership with the Grand River Conservation Authority Guelph Lake Nature Centre, a total of 700 local grade 7, 8 and high school students participated in guided educational tours of the City’s Water Services facility in 2012. These interactive tours lead students through the processes involved in supplying, treating, and distributing the City’s drinking water, as well as educate participants about the importance of water conservation and source water protection as essential parts of ensuring the sustainability of our City’s water resources. Beyond City lead programming, Water Services is proud to be an ongoing partner and sponsor of the Waterloo Wellington Children’s Groundwater Festival. This long standing festival in its 17th year and annually educates more than 4000 students in grades two through five in Guelph, Wellington County and the Region of Waterloo about the importance of water in their daily lives. Since 1996, over 70,000 students have been participated within the festival, which features fun and interactive activities designed to inform students of the importance of water protection and conservation. In partnership with the Upper Grand

District and Wellington Catholic School Boards staff have worked to increase local awareness and participation in this resource with upwards of 700 Guelph based students now participating in the event on an annual basis.

9. Canada Water Week

Canada Water Week, a national, week-long celebration of water, is held annually during the third week of March to coincide with World Water Day on March 22. In 2012, Canada Water Week was held March 19 to 25 and had a theme of “Discover your Water Footprint.” The theme was chosen to bring awareness to the water used daily in our homes and the water embedded in common products and services Canadian’s rely upon. In response, Guelph Water Services launched an accessible, engaging and interactive webpage, which included a video progress report to highlight community water conservation successes and future strategies in meeting the long-term water sustainability targets of the Water Conservation and Efficiency Strategy Update. Combined with a social media campaign, the progress report also reminded Guelph residents and businesses how they can use less water to reduce their water footprint. The City’s 2012 Water Conservation Progress Report can be viewed at guelph.ca/ourstoconserve.

In addition to the progress report, a number of City-partnered and independent community events took place during Canada Water Week. Events included a movie screening, the showcasing of efficiency projects and technology by some of Guelph’s water sector industry leaders, and social educational meetings organized by Innovation Guelph, Engineers Without Borders, and Guelph Green Drinks. These events brought local attention to our “water footprint” including water challenges and innovative solutions. More than 60 Grade 2 students at Sir Isaac Brock Public School spent nearly 80 hours painting a water-themed banner and taking the Blue Thumb pledge, in celebration of Canada Water Week, before it was put on public display at Guelph’s City Hall.

The week ended with an open house at Guelph Water Services, which included facility tours, information on wastewater treatment, source protection and water conservation programs. The result of the week’s events: a community-wide discussion around water and the awarding of the first-ever Canada Water Week Certificate of Recognition. The City of Guelph received this prestigious award for its outstanding efforts in building energy, support and awareness on water issues during the Canada Water Week celebration.

10. Peak Season Water Demand Management Reduction of peak season water demands continues to be a primary objective of the City’s Water Conservation programming. The ability to reduce seasonal water use limits impacts on our finite groundwater supply and creates operational efficiencies by reducing energy and chemical needs for treating and pumping additional volumes of water. Since 2001 the City’s Outside Water Use Program has helped to

Page 69: Summary Water Services Report - Guelphguelph.ca/wp-content/uploads/AnnualyWaterServicesReport_Jan-Dec... · Annual & Summary Water Services Report Page i of ii Executive Summary The

Annual & Summary Water Services Report

Page 64 of 69

manage peak season water use via regulatory controls with complementary programs, such as Healthy Landscapes, working to proactively manage potential peak demands by assisting residents and local business in establishing low outdoor water use environments. In 2012 the City’s Outside Water Program started the season in Level 1 – yellow on April 25, and later was elevated to Level 2 – Red on July 18, 2012 in alignment with declarations of the Level 2 conditions within the Eramosa River Sub-watershed by the Grand River Conservation Authority’s Low Water Response Team. This is largely attributed to lack of precipitation, high temperatures and low surface water flows throughout the entire watershed. . Precipitation in the winter of 2012 was 50 % of normal with frequent thaws throughout the winter resulting in limited spring flooding and a very small spring freshet. Like within much of Ontario, the preceding spring/summer months were very dry with precipitation levels for July and August being less than half of local 30 year averages for those months. As a result, stream flows consistently dropped throughout the summer months to trigger level 2 – Red conditions in July, and did not return to normal flow condition until November 2012.

With the need to enact watering restrictions early within the 2012 outside water use season, Water Services received numerous concerns from local stakeholders regarding the current by-law requirements as well as the relevance of some permitted activities in reference to current social norms and practices. In response to local concerns and changing weather patterns, the City’s Outside Water Use by-law will be going through a review process in 2013, with proposed revisions to the by-law stemming from this process to be provided to Guelph City Council for consideration in spring/summer 2013. In working to proactively manage peak season demand, the Healthy Landscapes Program offered various public resources throughout 2012. The annual Healthy Landscapes Workshop/Seminar Series featured numerous complementary talks on time of year appropriate outdoor water conservation topics including water efficient landscape design, plant selection and proactive maintenance best practices to manage the impact of drought and common turf pests.

In addition, a rain barrel truckload sale was organized in April of 2012 with over 600 rain barrels sold as part of the one day event. A native plant sale event was also held with the Wellington Wildflower Society in May 2012 through which residents could also purchase rain barrels. Rain barrels offer homeowners the benefit of capturing free volumes of water for outside use but also assist in managing stormwater impacts on private property. In total, over 700 rain barrels were sold during the 2012 season. The sale of rain barrels are a net zero service to the City as the barrels are sold at the bulk rate attained through an annual rain barrel tender process. Further to the above, the Healthy Landscapes assessment program continues to be a popular resource with 410 visits completed in 2012. This service offers a complementary site based consultation aiming to educate residents on garden design and maintenance practices to significantly curve outdoor demand at their home. Water efficiency studies completed in other Ontario communities have shown a net result of 74 litres per

Page 70: Summary Water Services Report - Guelphguelph.ca/wp-content/uploads/AnnualyWaterServicesReport_Jan-Dec... · Annual & Summary Water Services Report Page i of ii Executive Summary The

day per household during peak season as a result of similar water efficiency based landscape consultant services. For more information on the Healthy Landscapes Program please visit www.guelph.ca/healthylandscapes.

Water Reduction Target Progress In 2006 City Council endorsed the Water Supply Master Plan (WSMP). This detailed Master Plan evaluated the water demand associated with projected growth over a 50 year planning horizon, as well as alternative sources of new water supply. Water conservation was identified as the most cost-effective and immediately available source of new water supply and was ranked as the number one priority. The WSMP included three reduction targets based on 2006 daily water production volumes:

• Reduction of 10% (5,300 m3/day) in average day water use by 2010; • Reduction of 15% (7,950 m3/day) in average day water use by 2017; and • Reduction of 20% (10,600 m3/day) in average day water use by 2025

As of December 31, 2012, total annual average day water production has decreased by 6140 m3/day (12 per cent) since 2006, with an estimated direct savings of 4787 m3/day attributed to community participation in the City’s Water Conservation Program. This observed reduction to date places the City in a competitive position to reach its 2017 water reduction target. Further to the information above, the Figure 1 below shares water savings to date versus the annual conservation program reduction targets of the City’s 2009 Water Conservation Strategy:

Appendix “E” – Lead Reduction Plan – Update Report The City of Guelph’s (the City’s) Lead Reduction Plan (LRP) was developed in lieu of a Corrosion Control Plan (as outlined in Ontario Regulation 170/03 Schedule 15) and was submitted to the Ministry of the Environment (MOE) in April, 2011. The application for full regulatory relief from the lead sampling requirements of Schedule 15.1 and post-implementation monitoring program as part of the City’s LRP was subsequently fully approved on March 21, 2012. The purpose of this report is to provide an updated summary on continuing LRP initiatives and new LRP initiatives since January 2011. Please refer to the Lead Reduction Plan for detailed information on various programs and efforts prior to January 2011. The City has been working proactively to address the presence of lead service lines (LSL) in Guelph since 2007 through the identification and replacement of both the public and private portions of LSLs. Full LSL replacement has demonstrated to be affective in achieving regulatory compliance as well as significantly reduced lead concentrations as measured at the point of the water’s consumption. Partial LSL replacement has demonstrated to be less effective at reducing lead levels for regulatory compliance and reduce lead concentrations at the point of consumption. Since 2007 there have been 583 lead service lines replaced in the City. As a result, 86 percent of these homes are now considered to be ‘lead-free’ service lines (i.e., either a full replacement, a partial replacement connecting back to a non-lead material or a subsequent replacement of a privately-owned LSL by the homeowner). At the beginning of the program, the City conducted an extensive records review identifying approximately 3,750 known or suspected lead services. Through the Verification Sampling Program the number has been reduced to 520 suspected LSLs (as of December 31, 2012). This update report summarizes lead reduction through the identification and replacement of LSLs and subsequent post replacement monitoring. This report includes updated information on the following programs that support the overall Lead Reduction Plan:

− Legislated Lead Sampling under Schedule 15.1 (2011) − Water Service Verification Program results − Lead Service Line Replacement Program results and activities − Lead Water Service Replacement Grant Programs summary − Post-Replacement Sampling Program results − Post-Implementation Monitoring Program results − Water Filter Rebate Program activities − Description of outreach efforts
