Currently, all Redwood City’s drinking water is supplied by the regional Hetch Hetchy 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. This program includes identification, monitoring, and control of watershed characteristics and activities in the watershed that may have an adverse effect on the source water quality. The SFPUC also submits an annual watershed report to the California Department of Health Services (DHS) - Division of Drinking Water (see the link above). The Hetch Hetchy water supply meets all federal and State criteria for watershed protection, disinfection treatment, bacteriological quality and operational standards, allowing the SFPUC 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 trihalomethanes. The City is conducting on-going monitoring as required under the Lead & Copper Regulation. City personnel routinely collected 23 samples per week for bacteriological analysis. There are dedicated sampling stations throughout the distribution system.
