Watershed Sanitary Survey for the Alameda and Peninsula Watersheds and the Sunol Filter Galleries

SFPUC owns approximately 33 percent of the land in the Alameda and Santa Clara county watersheds and 99 percent of Peninsula San Mateo County watersheds. Non- SFPUC lands include the East Bay Regional Park District’s (EBRPD) Sunol and Ohlone Regional Wildernesses. Thus, a large degree of protection is afforded these watersheds, helping to assure maintenance of a high quality drinking water supply.

The California Surface Water Treatment Regulations requires that all surface water purveyors of drinking water conduct a watershed sanitary survey of their systems by January 1, 1996 and update it every five years thereafter. This watershed sanitary survey update was conducted to fulfill these State requirements for the SFPUC’s local watersheds.

The primary objectives of this survey are to:

• Fulfill the requirements of Title 22 of the California Code of Regulations. This report is an update to the 2000 Sanitary Survey.
  
• Present a description of watershed activities, summarize observations in the Alameda and Peninsula Filter Galleries for the period of 2001 through 2005.  The next update of this report is scheduled for 2010.

Attached below is the report.
