Designed as part of the water system to provide water to the San Francisco peninsula in the early 1900's. The system was owned by the Spring Valley Water Company until control was purchased by the San Francisco Water Department. Construction of the Hetch Hetchy Aqueduct made this system obsolete and led to its eventual abandonment. The site is currently closed to the public.
