Title

Harry Tracy Water Treatment Plant Long-Term Improvements Project

Description

The Project as approved by the SFPUC seeks to meet WSIP levels of service for water quality and delivery reliability, seismic reliability, and other improvements necessary to the enhance the operation of the HTWTP. The facility improvements include a new treated water reservoir, treatment process and chemical storage facility upgrades, and site improvements (pipelines, roads, slope stability, and erosion control). The project also includes decommissioning two existing treated water reservoirs, demolition of some facilities, and removal of equestrian facilities. The treatment process would generally be the same even with the proposed improvements. The primary differences would be to solids handling, whereby solids from the sludge holding tank would be transferred to a solids dewatering facility before being trucked off site, and to the treated water storage, which would occur in a single new tank north of the main plan site instead of two tanks southeast of the main plant. The HTWTP is located on 52.3 acres in an unincorporated area of San Mateo County just east of Interstate 280 (I-280) near the City of San Bruno and the City of Millbrae. A small portion of the site is within the City of Millbrae. Construction is anticipated to start early 2011 and last approximately 4 years.
