I. SUMMARY

Provide professional design engineering services for the project described herein including engineering studies, preliminary design report, permitting assistance, permitting assistance, preparation of bid documents, and construction phase assistance.

II. BACKGROUND AND PROJECT INFORMATION

The Orange County Water District (OCWD) manages the groundwater basin in northern and central Orange County, California by protecting, monitoring, and recharging the groundwater basin. Northern and central Orange County cities and water agencies (Producers) pump approximately 75% of their water demand from the groundwater basin to supply potable water to homes and businesses. The source water for OCWD’s groundwater recharge activities currently comes from Santa Ana River base flows and storm flows, purified recycled water from Groundwater Replenishment System (GWRS), incidental recharge, and imported water from Metropolitan Water District (MWD).

OCWD owns and operates the 100 MGD treatment capacity Advanced Water Treatment Facility (AWTF) as part of the GWRS that treats Orange County Sanitation District (OCSD) secondary effluent to drinking water standards and uses the purified water for both injection and percolation, through injection wells and recharge basins, as source water to replenish the groundwater basin’s drinking water supplies. Figure 1 shows the GWRS existing facilities.

GENERAL PROJECT DESCRIPTION

The GWR System AWTF has been operating successfully since January 2008. The original design of GWRS, included facility sizing and spacing for two phases of 30 MGD treatment capacity expansions to the AWTF. The first 30 MGD expansion of the AWTF was completed in June 2015. This GWRS Initial Expansion Project increased the AWTF treatment capacity from 70 MGD to 100 MGD. The second phase expansion of 30 MGD is the GWRS Final Expansion Project and will increase the AWTF treatment capacity from 100 MGD to 130 MGD. The GWRS Final Expansion Project will incorporate all improvements required to complete the 130 MGD build-out treatment capacity. In order to increase the capacity of GWRS for the Final Expansion Project, the AWTF will require additional microfiltration cells, reverse osmosis units, ultraviolet vessels, and associated equipment in order to produce an additional 30 MGD of purified water. These improvements are referred to as the AWTF improvements. In addition to the AWTF improvements, for the GWRS Final Expansion Project, additional source water from OCSD’s wastewater treatment plants is required. With AWTF treatment process efficiencies, approximately 40 MGD of secondary effluent is required from OCSD to produce the additional 30 MGD of purified water through AWTF. This additional 40 MGD of secondary effluent will be pumped to the AWTF from OCSD’s Treatment Plant No. 2 located in Huntington Beach. Facilities to convey this secondary effluent to GWRS include an effluent pump station, a flow equalization tank and pipeline which are referred to as the Secondary Effluent Conveyance Facilities.

The combined Secondary Effluent Conveyance Facilities and AWTF Expansion will allow the GWRS facility to produce the total 130 MGD GWRS Final Expansion production capacity. These projects will be referred to as the GWRS Final Expansion (GWRSFE) Project within this


document. The additional 30 MGD of purified water will be used as a new source of replenishment water for the Orange County groundwater basin.

DESCRIPTION OF GWRSFE PROJECT ELEMENTS

PROJECT ELEMENT 1 – ADVANCED WATER TREATMENT FACILITY EXPANSION

This is the Advanced Water Treatment Facility Expansion to increase treatment capacity by 30 MGD for the GWRSFE Project . The following components apply to this project:

Screenings Facility

The current screenings facility is comprised of an underground concrete box with an overflow weir. The overflow weir conveys the secondary effluent to OCSD’s ocean outfall discharge. The secondary effluent entering into this box and is conveyed to the microfiltration facility for treatment through the AWTF, if it does not pass the overflow weir. The Consultant shall evaluate the impact of an additional ~40 MGD of secondary effluent entering into the screenings facilty. This evaluation shall include any OCSD treatment facilities surges or outages that may cause secondary effluent to overflow the screenings facility.

Microfiltration Treatment Expansion

The current microfiltration (MF) system for the AWTF is a Evoqua CS submersible system with polypropelene hollow fiber membranes. The current system is comprised of 36 MF cells that have the capacity to treat up to 4 MGD each. The Consultant will be asked to evaluate the number of additional cells required to increase the AWTF treatment capacity by 30 MGD based on the evaluation of two different types of MF membranes. The Consultant will be given information from the two membrane suppliers to complete the evaluation.

OCWD will enter into a pre-selection procurement contract with the recommended MF membrane supplier. The Consultant will perform the final design based on the chosen membrane supplier. The membrane supplier will provide shop drawings and other pertinent design information required to complete the final design. In general, the following facilities will be the Consultant’s responsibility to design to accommodate the number of additional cells required for the expansion: the process piping, hydraulic structures, building/basement expansion, blower system, electrical components, process control system components, clean-in-place system, and piping design.

The Consultant shall also evaluate the MF system redundancy and allow for at least two cells to be out of service but still maintain 130 MGD water production.

The Consultant shall also evaluate the hydraulic capacities of using MF cells to meet the treatment requirements of OCWD’s Green Acres Project (GAP) Title 22 Treatment Facility. The Consultant shall present the number of additional MF cells required to treat secondary effluent to produce 6 MGD GAP Effluent.

The Consultant shall also evaluate the demolition and relocation of the AWTF west entrance gate due to potential blocking of this existing gate due to the microfiltration basement and electrical building expansion.

Transfer Pump Station Expansion


The RO Transfer Pump Station transfers MF Effluent/Filtrate from the MF break tank to the RO treatment system. Ensure the capacity of this system is adequate for 30 MGD increase in treatment capacity.

Cartridge Filter Expansion

The cartridge filters upstream of the RO system will need to be expanded. Four new cartridge filter vessels will have to be installed to filter the MF Effluent prior to the RO. The Consultant shall evaluate the hydraulic loading of each unit to ensure adequate design velocities through the piping/filters are being met. The Consultant shall design piping and modifications necessary to enable the cartridge filters to be flushed and dosed with chlorine during plant shutdowns.

Chemical Feed System Expansion

The chemical feed system for the AWTF will need to be evaluated for the additional 30 MGD of capacity added. The Consultant shall evaluate/predict secondary effluent water quality in the predesign evaluation discussed in more detail in Section IV. Based on this predicted secondary effluent water quality to the AWTF, the Consultant shall evaluate which improvements are required to any of the chemical feed systems to provide the predicted chemical dosage required with the expansion. The chemical feed systems for the AWTF include: sodium hypochlorite, citric acid, MF membrane cleaning chemical, sodium hydroxide, sulfuric acid, threshold inhibitor, and hydrogen peroxide.

At a minimum one new sulfuric acid tank and pump dosing system will need to be designed for the increased 30 MGD capacity.

The Consultant shall also evaluate the chemical injection ports and determine if the existing in-line static mixer is providing adequate mixing. The Consultant shall also propose an alternative in-line mixing system.

Reverse Osmosis Treatment Expansion

The Reverse Osmosis (RO) Treatment System will require, at a minimum, two new RO trains with three units in each train to expand the treatment capacity by 30 MGD. With the results of the Evaluation Memos – the Consultant shall evaluate the need for Energy Recovery Devices, interstage boosters, and/or RO Feed pump changes on both existing and new RO units to produce 130 MGD with the predicted AWTF Final Expansion influent from OCSD. This includes evaluation of existing RO high pressure feed pump capacity to maintain current unit flow and recovery based on the predicted AWTF Final Expansion influent from OCSD.

The Consultant shall evaluate the existing Energy Recovery Devices (ERD) on Trains F & G to determine if their existing configuration will boost the existing RO Feed Pumps based on the predicted influent water quality (Evaluation Memo 1) for GWRSFE.

The Consultant shall evaluate the site configuration of these new trains to allow for an future addition of a (5 – 23 MGD treatment capacity) RO Concentrate Recovery Unit.

Ultra Violet Light Treatment Expansion

The existing UV system for the AWTF is a Trojan UVPhox low pressure system. It is anticipated that the same supplier will provide the three new UV trains to expand the treatment


capacity by 30 MGD. OCWD will enter into a pre-selection agreement with the UV supplier and the Consultant will be required to incorporate the supplier information into the final design. The Consultant shall anticipate having the UV supplier submittal information on or before the Preliminary Design Report due date.

The equipment contract for the UV supplier will be assigned to the GWRSFE contractor . The preselected UV manufacturer will provide shop drawings and other design information required to build-out the UV trains. The Consultant shall be primarily responsible for the design of the process inlet/outlet piping, the electrical system, the hydraulic structures, and the process control system components and configuration.

Post Treatment System Expansion

The post treatment consists of decarbonation and a lime stabilization process. The Consultant shall determine how many decarbonators are needed as well as what changes are required to the lime system and decarbonation bypass piping to accommodate the increase treatment capacity. The Consultant shall consider hydraulics of existing decarbonators and bypass for flexibility in process control. The Consultant shall also evaluate the existing bypass flow capacity and determine if more bypass capacity is needed and develop solutions to achieving more bypass.

At a minimum the Consultant shall design for one additional decarbonator tank, media and blower.

The Consultant shall review maintenance issues with the current proprietary polymer feed system for the lime saturators and recommend a alternate non-proprietary polymer feed system, an alternative polymer, or revisions to the existing system for to correct maintenance issues and increase operational ease.

Product Water Pump Station Expansion

The existing Product Water Pump Station pumps AWTF product water to the recharge basins in Anaheim via the 13-mile GWRS pipeline. The Consultant shall determine how many pumps and what changes will need to be implemented to the existing pump station and associated surge tank system to accommodate the increased production and variable flowrate of the expanded AWTF. The operation of the Product Water Pump Station will be modified with the incorporation of the Burris Booster Pump Station Project, which is expected to be completed in 2022, along the GWRS Pipeline. The Consultant shall plan for at least one coordination meeting with the Burris Booster Pump Station Project design consultant to ensure the Burris Booster Pump Station Project can still be accommodated if revisions to the Product Water Pump Station are recommended.

In addition, the Consultant shall include details for modifications to the existing surge tanks in the final design submittal for work to be completed by the contractor. These modifications include the addition of an access manhole and recoating of the interior of the surge tanks.

For the GWRSFE Project, secondary effluent from the Trickling Filter/Solids Contact (TF/SC) facility at OCSD Plant No. 2 will be conveyed to the AWTF to provide the additional flows required to expand the AWTF to produce an additional 30 MGD of purified water. Due to the proximity of OCSD Plant No. 2 to the coast and TF/SC treatment facility – OCWD predicts the influent water quality may be substantially different for the GWRSFE project as to the current AWTF influent water from OCSD Plant No. 1. The Santa Ana Regional Interceptor (SARI) raw wastewater sewer currently is conveyed to OCSD Plant No. 2. These


SARI flows will be segregated and treated separately at OCSD Plant No. 2 such that these SARI flows will not be conveyed to the AWTF for recycling. This removal of the SARI flows from the predicted influent water quality for GWRSFE should also be reflected in the evaluation.

Therefore, this Evaluation Memo 1 shall serve to establish a predicted influent water quality for the GWRSFE Project that changes depending on the predicted flow ratios from each OCSD Plant No. 1 and Plant No. 2 facilites to feed the AWTF. OCSD and OCWD will meet to establish a minimum and maxiumum flow ratio from each facility to convey to the Consultant.

OCWD will provide water quality data from the following facilities to assist the Consultant in this evaluation: OCSD Plant No. 1 Effluent, SARI Influent, and OCSD Plant No. 2 TF/SC Effluent.

In particular, OCWD will provide water quality data from OCSD Plant No. 1 Advanced Secondary and Trickling Filter Effluents, OCSD Santa Ana Regional Interceptor (SARI) raw wastewater influent, OCSD Plant No. 2 raw wastewater headworks influent, OCSD Plant No. 2 Trickling Filter/Solids Contact primary influent, OCSD Plant No. 2 Trickling Filter/Solids Contact effluent for the consultant to complete this task. Consultant shall plan to meet for at least three 2-hour meetings with OCWD and OCSD, as needed, to determine the average flow ratios from OCSD Plant No. 1 and OCSD Plant No. 2 for GWRSFE predicted influent and to discuss/review water quality data. The predicted GWRSFE Final Expansion influent water quality shall be used to determine necessary treatment process upgrades, if needed, for the Advanced Water Treatment Facility.


Water Quality data provided by OCWD will be for the following constituents:

General WQ/Minerals Metals Nutrients Organics

Total Alkalinity Aluminum Ammonia Nitrogen Total Suspended Solids

TASK 2.2 EVALUATION MEMO 2 – TREATMENT PROCESS EVALUATION

The Consultant shall prepare Evaluation Memo 2 based on the findings from Evaluation Memo 1, in which the predicted GWRSFE influent water quality is established, and evaluate the predicted influent water quality for treatment effectiveness through the following existing AWTF treatment processes: MF, RO, UV, and post treatment. The Consultant shall evaluate the existing treatment processes and determine if the existing treatment process can remain unchanged with the predicted influent water quality or if changes will be required to meet current AWTF effluent water quality.

If the current AWTF treatment processes are unable to treat the predicted influent water quality for GWRSFE, the Consultant shall recommend at least two alternative process upgrades that will provide the level of treatment of the existing AWTF.


OCWD will provide the GWRS annual report data which details current AWTF water quality before and after each treatment process. Based on the findings within this Evaluation Memo 2, OCWD will decide if any treatment process upgrades will be required to be incorporated into the design documents for the GWRSFE Project.

TASK 2.3 EVALUATION MEMO 3 – MICROFILTRATION MEMBRANES

The Consultant shall prepare an Evaluation Memo which evaluates the number of MF cells required to treat the additional ~40 MGD of secondary effluent required to meet the production goal of 130 MGD total as part of the GWRSFE Project. The evaluation shall consider the GWRSFE influent predicted water quality while continuing to use the existing CS submersible polypropylene microfiltration memebranes. The Consultant shall design the MF treatment capacity to accommodate two redundant MF cells which can be placed out of service while the AWTF will continue to meet the 130 MGD production goal. In addition to the redundancy the Consultant shall factor in addional MF cells required to produce tertiary treated effluent for OCWD’s Green Acres Project (GAP). The Consultant shall assume the GAP costumers to have a maximum night time demand of 6 MGD and therefore 6 MGD of MF treatment capacity shall be added into the analysis.

OCWD is concerned that the predicted influent GWRSFE Project water quality may reduce the treatment capacity of the existing MF process resulting in the need to construct more than the 12 new MF cells referenced in the project elements to meet the 130 MGD production goal.

OCWD has been pilot testing various alternative MF and Ultrafiltration (UF) membranes. The Consultant shall evaluate flux, chemical cleaning frequency, cleaning chemical dosages for two additional MF/UF membranes for use to treat the additional ~40 MGD of secondary effluent (with two redundant MF cells and GAP demands). The flux, cleaning frequency, and cleaning chemical dosage data will be provided to the Consultant through pilot study data from OCWD. Based on the data given, the Consultant shall evaluate the number of MF cells required to treat the additional ~40 MGD for each of the alternative membranes. In addition, the Consultant shall evaluate the necessity for additional chemical storage and dosing system based on the cleaning dosage and frequency for the alternative membrane.

This evaluation shall be completed to a ~30% design level to compare the number of additional MF cells required, the extent of the MF cell structures, the new chemical storage facilities needed, and the new chemical dosing system needed. The Consultant shall also verify that the existing influent and effluent piping can accommodate the alternative membrane predicted production flows. The Consultant shall also evaluate if any changes to the MF suction pumps and aeration blowers will be required with the use of the alternative membranes. A construction cost estimate shall also be included as part of this evaluation for the existing polypropylene membranes and the two alternative MF/UF membranes analyses. The estimates shall compare the cost of all three MF systems (existing polypropylene and two alternative membranes) based on the number of membranes needed, number of cells needed, and frequency and type of chemical cleaning required.

OCWD will review this evaluation memo to make a decision on the type of MF membrane to implement for the additional MF treatment required as part of the GWRSFE Project. The MF membrane system recommended for the GWRSFE Project shall be incorporated into the Preliminary Design Report. OCWD will enter into a pre-selection agreement with the recommended MF system supplier after this Evaluation Memo is finalized. The system supplier


will provide piping, header, and membrane design criteria required to complete the final design submittal.

TASK 2.4 EVALUATION MEMO 4 – EXISTING PIPELINE EVALUATION
