Post Information Posted At: Thu, Sep 28, 2023 10:00 AM Sealed Bid Process: Yes (Bids Sealed / Pricing Sealed) Private Bid: No 1. Introduction 1.1. Summary The City of Santa Monica (referred to hereafter as “the City”) is seeking proposals from qualified firms to provide an analysis and update the City’s current water and wastewater facilities’ security systems. 1.2. Background The City is an urban coastal community, bordered to the west by the Pacific Ocean and to the north, east, and south by the City of Los Angeles. The City’s Department of Public Works – Water Resources Division provides water, wastewater, and recycled water services to over 90,000 residents and over 2,700 commercial customers. To provide these services, the City owns and operates several assets. As-Builts for major treatment facilities and reservoirs can be found in attachments uploaded in the RFP posting. Facilities include: Groundwater Production and Injection Wells Charnock Well Field (5 production wells) Olympic Well Field (3 production wells and 1 injection well) Arcadia Well Field (2 production wells) San Vicente Well (Santa Monica Well 1) Drinking Water Treatment Plants Charnock Water Treatment Plant (Charnock WTP) - Attachment A Arcadia Water Treatment Plant (Arcadia WTP) - Attachment B City Hall East (CHE) Water Treatment System Drinking Water Reservoirs Arcadia Reservoir - Attachment C Mt. Olivette Reservoir - Attachment D San Vicente Reservoir and Booster Pump Station - Attachment E Riviera Reservoir - Attachment F Wastewater Lift Stations Moss Avenue Pump Station (MAPS) - Attachment G Wilshire Pump Station and Diversion Structure Montana Wastewater Pump Station and Diversion Structure Recycled Water Treatment Plants, Pump Stations, and Storage Tanks Santa Monica Urban Runoff Recycling Facility (SMURRF) Clean Beaches Initiative Tank Pico-Kenter Storm Drain Lift Station Sustainable Water Infrastructure Project Advanced Water Treatment Facility (SWIP AWTF) Civic Center Stormwater Harvesting Tank Ocean Avenue Wastewater Lift Station Pico Boulevard Stormwater Lift Station and Civic Center Drain Lift Station Drinking Water and Recycled Water Distribution Systems Over 200 miles of drinking water distribution mains Three drinking water pressure relief stations Over 10 miles of recycled water distribution mains Wastewater and Storm Drain Collection Systems Over 150 miles of wastewater collection pipes and two flow monitoring stations Over 60 miles of storm drains and five outfall locations City of Santa Monica Water Yards The City obtains its local groundwater from the Charnock, Olympic, and Arcadia subbasins, with limited supply also from Santa Monica Well 1. The Charnock Well Field, located in the Charnock subbasin, has five groundwater wells. Under normal operating conditions, groundwater production from the Charnock Well Field averages approximately 8,000 AFY. In the mid-1990s, Methyl Tertiary Butyl Ether (MTBE) contamination was discovered in the groundwater and Charnock Well Field was shut down. In 2006, the City reached an agreement with the responsible parties for the contamination to restore the Charnock Well Field. This agreement resulted in the construction of the Charnock Water Treatment Plant, which uses greensand filtration and granular activated carbon (GAC) for well head treatment to remove MTBE. The treated water from Charnock WTP is then sent to Arcadia WTP for additional treatment before it is distributed for potable uses. The Charnock Well Field and Charnock Treatment Plant are located on the same property, owned by the City, which is at a private school and is surrounded by a residential neighborhood. Each Charnock well is beyond the primary fence line of the water treatment facility. The Olympic Well Field is located in the Olympic subbasin, along the median on Olympic Boulevard at the eastern end of the City and has three groundwater wells. Under normal operating conditions, groundwater production from the Olympic Well Field is approximately 2,500 AFY. Like Charnock, the Olympic Well Field has also experienced contamination from industrial sources. Volatile organic compounds (VOCs), trichloroethylene (TCE), tetrachloroethylene (PCE), carbon tetrachloride (CTC), and 1,4-Dioxane have limited groundwater production in the well field. To restore the Olympic Well Field, the City embarked on the Olympic Well Field Restoration Project in 2020 to treat the groundwater from Olympic and restore its production capacity. The project will add ultraviolet light advanced oxidation (UV AOP) and GAC to treat water at the wellhead, remove contamination, and increase the production capacity to 3,200 AFY. The new wellhead treatment facility is co-located at Arcadia WTP, and completion is anticipated in Spring 2024. Each Olympic well, plus Santa Monica Well 1, is an independently-enclosed, standalone well site. The City also owns and operates the Arcadia Water Treatment Plant. The Arcadia WTP has a raw water treatment capacity of 10 million gallons per day (MGD), however, it is currently under construction to expand the treatment capacity to 13 MGD. The Arcadia WTP expansion is expected to be completed in Spring 2024. The updated facility will include new pipelines, flow-reversal reverse osmosis to enhance production efficiency, and a new booster pump station. After treatment at Arcadia WTP, water is sent to the 5 million-gallon (MG) Arcadia Reservoir on-site and distributed to the City’s other three water storage reservoirs before it is sent to the City’s customers for potable water use. The City owns and operates three additional domestic water storage reservoirs: Riviera Reservoir (25 million gallons), Mt. Olivette Reservoir (5 million gallons), San Vicente Reservoir (5 million gallons). All four reservoirs are capable of receiving a blend of purchased treated imported water from the Metropolitan Water District of Southern California (MWD) and treated local groundwater with a total storage capacity of approximately 40 MG. The City’s water distribution system is divided into three pressure zones to regulate pressures in the water system: 500’, 350’, and 250’ zones. The existing domestic water system and the various zones are shown in Figure 1. The City owns and operates its water recycling and stormwater and urban runoff treatment systems: the SWIP AWTF and SMURRF. The SWIP AWTF treats a blend of stormwater and wastewater and can produce 1 MGD of advanced treated recycled water. The AWTF will be operational towards the end of 2023 to provide advanced treated recycled water for non-potable and potable reuse. SMURRF was originally constructed in 2000 as a stormwater best management practice facility and treats a blend of urban runoff and brackish groundwater. The SMURRF was recently upgraded with the installation of a reserve osmosis system to enhance treated water quality and will now produce Title 22 diluent water that is suitable for groundwater recharge. Treated water from both the SWIP AWTF and SMURRF will be used for non-potable and potable reuse. Additionally, the City owns and operates MAPS, which pumps wastewater along the coast from northern Los Angeles, through Santa Monica, and eventually to Los Angeles’s Hyperion Water Reclamation Plant. MAPS was constructed in 2000 and has a design capacity of 26 MGD. The existing sanitary sewer system is shown in Figure 2. The City’s storm drain system diverts water away from the streets and into the Santa Monica Bay. There are five storm drain outfalls that discharge into ocean: Pico-Kenter storm drain, Pier storm drain, Wilshire storm drain, Montana storm drain, and Ashland storm drain. All five storm drains have above ground electrical cabinets. The City’s Water Resources Division’s water distribution and wastewater collection operations are located at the City Water Yards, which includes offices and locker rooms for staff, equipment storage, and construction vehicles. The Water Resources Division is also responsible for an on-site water treatment system located in the basement of the CHE to serve the building’s potable water supply. A comprehensive site security risk assessment has not been previously completed for the City’s water, wastewater, and recycled water facilities. Security measures at these assets must be reviewed and updated to align with current industry guidelines and standards.
