Document Description
The project will install a seismically-resilient water pipeline that begins in the City of Millbrae at the existing San Francisco Public Utilities Commission (SFPUC) Helen Turnout on Helen Drive and ends at the Town of Hillsborough's Darrell Tanks located slightly southwest of Darrell Road. The purpose of the project is to provide an additional connection to the Town's water supply from SFPUC's system in the higher-pressure zones in the event water cannot be delivered from SFPUC to the Town's lower pressure zones. The proposed pipeline will provide a reliable water source within and adjacent to the Wildland Urban Interface to increase fire suppression resources and protect critical water storage and distribution infrastructure, as well as the residents of all three municipalities. The new pipeline will provide an approximate flow target of 6 million gallons per day.
