Document Description
The City proposes to approve the Sunnyvale Water Pollution Control Plan Master Plan for the Donald M. somers Water Pollution Control Plant. The proposed Master Plan will serve as a long-term guide for upgrading and replacing the WPCP's facilities and operations. The purpose of the Master Plan is to ensure that the WPCP can meet changing regulations, treat existing and projected wastewater flows reliably and cost-effectively, and increase recycled water production. The Master Plan yielded a preferred site plan and a series of capital improvement projects, including replacement of existing and construction of new facilities, to be phased in over the next 20 or more years at and near the WPCP. Many of the existing buildings and processes at the WPCP site would be decommissioned and replaced with new buildings and processes. Improvements planned outside of the main plant area include construction of basins and tanks for emergency water storage and relocation of Bay Trail access to Caribbean Drive. The City is also contemplating implementation of a variation of the Master Plan in partnership with the Santa Clara Valley Water District (District) to produce purified water at the WPCP. Implementation of the "Water Purification Facilities" (WPF) would alter the WPCP site layout and some of the treatment processes in order to produce purified water for groundwater recharge at locations south of the WPCP.
