Title

Cater Water Treatment Plant's Finished Water Reservoir Resiliency Project

Description

The Project consists of the replacement of the existing sludge drying bed with a more efficient 2.5-million-gallon (MG) chlorine contact basin at the Cater Water Treatment Plant, along with upgrades to the plant’s existing finished water reservoir and sludge drying bed. The replaced equipment is located within the existing developed area, therefore, there is no change to the footprint. The Project is expected to affect Cater’s parcel Assessor’s Parcel Number (APN) 055-171-007, along with two additional parcels south of the Cater Water Treatment Plant and San Roque Road as a proposed staging area APNs 055-172-028 and 055-172-030. The existing finished water reservoir will be modified to connect the proposed contact basin to the plant hydraulically and to strengthen the existing reservoir’s structure. The upgrades to the finished water reservoir will bring this component to meet modern standards, there is no change in facility capacity. The existing Solids Recovery Basin (SRB) # 3 and retaining wall adjacent to the reservoir will be demolished to make space for a chlorine contact basin. The existing gravel road along the west edge of the water treatment plant will be extended to connect the road to the south portion of the plant. The existing roadway will be improved to allow for internal site access with heavier vehicles while still maintaining the permeability characteristics of the roadway. The new portion of the roadway will have the same characteristics. The minor roadway improvements are ancillary to the primary use, and do not expand or increase capacity of the primary use. Additionally, electrical conduits and two pipes located under the existing paved accessway will be rerouted to avoid interference with the proposed contact basin and placed under the improved road. The existing sludge drying bed will be modified to improve access for solids storage and removal. A new biofiltration basin and associated stormwater piping will be installed to manage stormwater in the project area. The Project also includes the installation of ground mounted solar panels with approximately 600 kilowatts (kW) production area to offset roughly half of the power demand of the Plant and improve energy efficiency. The solar panels will be installed in a ballasted racking system where concrete blocks are placed in the system to weigh down the solar array.
