Document Description
The proposed project would construct the Baker Water Treatment Plant (WTP) onsite at the existing Baker Filtration Plant in the City of Lake Forest. The proposed proect also would include a new offsite pump station near Peters Canyon Reservoir; a new non-reclaimable waste (NRW) pipeline to convey NRW from Baker WTP to IRWD's sanitary sewer; and may include new pipelines to convey treated water from the Baker WTP to the South County Pump Station and Pipeline. The proposed project would provide increased water supply reliability in southern Orange County by creating redundancy of treatment system capacity, redundancy of distribution infrastructure for potable water, and local treatment capability for variable raw water supply sources.
