Currently, all Redwood City’s drinking water is supplied by the Hetch Hetchy regional water system, operated by the San Francisco Public Utilities Commission (SFPUC). The Hetch Hetchy system provides high quality drinking water to over 2 million people in the Bay Area. The SFPUC maintains a watershed control program that effectively limits or eliminates potential contamination to the water supply. The Hetch Hetchy water supply meets all federal and State criteria for watershed protection, disinfection treatment, bacteriological quality and operational standards, allowing the SFPUC and Redwood City to provide its customers exceptionally high quality drinking water.
Redwood City routinely monitors the distribution system for bacteriological quality, chlorine residual, general physical parameters and disinfection by-products. The City conducts tri-annual monitoring as required for Lead & Copper, and routinely collects 23 samples per week for bacteriological analysis from 51 dedicated sampling stations throughout the water distribution system.
