Berkeley History
Site of pump House 
Peet Brothers / Colgate Palmolive 
In the early 20th century, a thriving manufacturing district grew up in 
southwest Berkeley. This is the site of a former salt water pump house, 
located on what was once the east shoreline of San Francisco Bay. The 
pumps supplied water used in the production of soap at the Peet Brothers 
Soap Company plant located a quarter of a mile from here. Remnants of 
the salt water pipelines are visible in the west embankment of the Southern 
Pacific Railway track.  The Peet Company, which began in 1916, later 
merged with Colgate and Palmolive. The plant continued to manufacture 
soap, glycerin, detergents, cosmetics, and related products until it closed 
in 1982. In 2000, Bayer corporation purchased the plants property and 
constructed this platform and walkway. They have donated it to the city 
of Berkeley for public enjoyment.
