SECTION 2 OVERVIEW 2.1 INTRODUCTION

.1 Problem identification: high levels of Inflow and Infiltration (I/I) flow in the sanitary sewers were observed through the City's 2008 and 2013 flow monitoring programs. The high I/I flow reduced the capacity of the sanitary sewer system and Wirral Court Sanitary Pumping Station, which contributed to basement flooding in the drainage area during heavy rainfalls.

.2 The City's work plan: the City of Toronto (City) plans to undertake an Inflow and Infiltration (I/I) reduction pilot project for Wirral Court drainage area using a holistic approach. The objective of the project is to reduce peak I/I under Wet Weather Flow (WWF) conditions to a level close to 0.26 L/s/ha, which is the I/I allowance used in the sanitary sewer system design. The pilot project will be carried out in three phases:

Phase 1: Development of an Inflow and Infiltration Reduction Strategy for the

Wirral Court Sanitary Pumping Station drainage area (2016) Phase 2: Implementation of the I/I Reduction Strategic Action Plan developed

through Phase 1 (2017-2018) Phase 3: Assessment of effectiveness after implementing the I/I reduction

measures in Phase 2 (project evaluation post-construction) and developing

recommendations for City-wide I/I Investigation and Reduction Program. (2019-

2020)

.3 Purpose of this RFP: the City of Toronto (City) is seeking for a qualified team to provide engineering and field investigation services for Phase 1.

.4 The project area is the entire drainage area serviced by the Wirral Court Sanitary Pumping Station. This area lies over approximately 100ha excluding the cemetery area, and is bounded by Midland Avenue to the west, Anson Avenue to the north, and Kingston Road to the south and east. (See Figure 2-1). The project area includes approximately 1,000 address points with single residential home being the dominated land use (approximately 80%). According to 2011 census, a total of 5,300 population resided in the drainage area. VIEW

2.2 BACKGROUND INFORMATION

.1 The project area is drained by separated sanitary and storm sewers which were majorly (70%) built in 1950s. While the storm sewer flows being conveyed to the storm sewers outside of the project area, the sanitary flows in the project area are all drained to the Wirral Court Sanitary Pumping Station. The pump discharge is connected to the combined sewer system along Midland Avenue via a 250 mm forcemain.

.2 The Wirral Court Sanitary Pumping Station built in 1956 is equipped with two (2) pumps with each rated at 65.5 L/s, which is the firm capacity of the PS.

.3 The total length of the sanitary sewers, excluding the laterals, is about 11 km in the City's Right-of-Way with about 150 maintenance holes. The sizes of the sanitary sewers are mostly (80%) 200mm - 250 mm diameter with 300mm - 375mm diameter for the remaining.

.4 The total length of the storm sewers, excluding the laterals, is 11 km in the City's Right-of-Way with 161 maintenance holes. The sizes of the storm sewers range from 300mm to 1350mm.

RFP No. 9117-15-7263

.5 A specialized contractor, hired by the City is currently undertaking a closed-circuit television (CCTV) inspection of the sanitary and storm mainline sewers including associated maintenance holes in the project area. The inspection is anticipated to be completed by September 2015. Note that laterals are not currently included in the inspection. As shown in Figure 2-2, approximately 30% of each of the sanitary pipes and storm pipes, in terms of length, have been inspected from 2007 to 2013 year. The previous CCTV inspection indicates that the prevalent issues are encrustation in the storm pipes and grease in the sanitary pipes. Less recurrent defects (common to both sewers) are debris, cracks, and joint displacement.

.6 The Vendor is expected to review the CCTV and recommend rehabilitation of the main line sanitary sewers. The City plans to complete rehabilitation of the local collection system within in the study area through an ongoing sewer rehabilitation program which will reduce some of the I/I on the public side. The primary focus of this project is to identify the I/I sources generated from private and public local sewage system components including downspouts, basement drains, lateral connections, cross connections etc. Downspout disconnection is mandatory as per City of Toronto Downspout Disconnection Bylaw.

.7 Sanitary sewer flow monitoring had been conducted in 2008 and 2013. The monitored locations are shown in Figure 2-3. Plots of the 2008 and 2013 flow data are attached in Appendix E and the digital data will be provided to the Vendor. After observing high I/I from the 2008 flow monitoring data, dye testing and smoke testing in some of the project area were conducted, some of the roof drain connections to the sanitary sewers were identified. It is not clear to the City whether and/or how many of the identified illegal connections have been removed as this is a homeowner’s responsibility to make the correction.

.8 Therefore, the City conducted a flow monitoring program in 2013 to monitor the WWF in the sanitary sewers. In addition, the 2013 flow monitoring program was also to monitor the changes in the sanitary flows under Dry Weather Flow (DWF) and WWF conditions as new developments in the north-east corner of Midland Ave. and St. Clair Ave. have been added into the drainage area since 2009. Sewer plans and profiles for the new development area will be provided to the Vendor at a later date during the project.

2.3 CURRENT STUDIES AND POLICIES

.1 The following section describes some of the related projects and activities currently underway within Toronto. Some may only have a minor impact on the proposed project. The information has been made available to provide perspective on the current situation.

The project area in this RFP was Cluster 5 in the completed Basement Flooding Class Environmental Assessment (EA) Study Area 33. The EA recommendation for Cluster 5 was to confirm the extent of private property interconnections, disconnect the downspouts and undertake further monitoring to determine if this reduces the inflow and infiltration. Information on the EA study is available in the City’s website at: http://www.toronto.ca/involved/projects/basement_flooding/completed.htm

The Inflow and Infiltration Reduction Study for Basement Flooding Study Area 9 was initiated in June 2015. One of the conclusions of the completed Basement Flooding Class Environmental Assessment (EA) Study for Area 9 was that the majority of the basement flooding in the area is caused by excessive I/I into the sanitary sewer system. The purpose of this study is to locate and quantify sources of I/I, determine the remedial works necessary to significantly reduce I/I, and to provide a framework for quantifying the success of the recommended remedial works after the remedial works are completed in the area.

These documents include but not limited to: pilot project description/flyer, notices of inspection, public information presentations, permit to enter agreement, door hangers, frequent questions and answers. The following clauses provide additional and project specific requirements and are to be read in conjunction with the Appendices. Where there is a conflict, the provisions in this section shall take precedence.

.1 The Vendor will work in conjunction with the City of Toronto Public Consultation Unit (PCU). A staff person will be assigned to the project and will be part of the project team. This staff person, through the City’s Project Manager, will provide input on all draft public notification materials prepared by the Proponent (e.g. field investigation notices, etc.). Public consultation staff will be involved in the planning for the project with the Proponent as early in the project as possible, and the Proponent is to include sufficient time for interactions with the PCU. In addition to the monthly progress meetings, allow two (2) additional meetings with PCU on an as needed basis. The Proponent will be responsible for the preparation of all draft public notification materials.

.2 A public information event may be necessary to inform the property owners that will be affected by the inspection of connected downspouts, foundation drains, etc., of the field testing procedures and impacts (e.g. smoke and dye testing), and address any questions or concerns. One public consultation session is planned for the project study area. The Proponent shall include the cost to prepare materials and attend one public information event for this purpose.

.3 A similar public information event may be necessary to inform the property owners the inspection results, the required remedial works in their properties, and address any questions or concerns. The Proponent shall include a unit cost to prepare materials and attend one public information event for this purpose. This is kept as a provisional item in Part B of Table 7-1 for all costs related to this public information event.

.4 The public consultation services to be provided by the Proponent for this project include the following: draft and final field investigation notices, regular update notices for all field investigations and remedial works (including clean-out installation if required), review and input on legal agreements required to access private properties (including both indoor and outdoor) to conduct inspections, and a point of contact to manage and answer questions or concerns from the public (contact information for this person will appear on the notices). The Proponent's qualifications, approach, and resources with regards to Public Consultation should be identified in the relevant sections of its proposal (refer to Section 6 of this RFP) and priced (in accordance with Section 7 of this RFP) accordingly.

.5 It is anticipated that the extent of public consultation for this project will include notifying residents of all field investigations, including lateral CCTV inspections, micro-monitoring, smoke and dye testing, connected downspouts, area drains, lot grading, and foundation drains, and installation of clean-out if required.

.6 All materials prepared by the Proponent will be reviewed by the City Project Team prior to being finalized for publication. To allow for sufficient review time and revision completion, all public information materials must be drafted at least three weeks prior to publication.
