New Reservoir to Increase Supply in Bayshore District

Cal Water will soon begin a water infrastructure improvement project in its Bayshore District that will dramatically increase the amount of water storage available for residents in San Mateo.

Cal Water will construct a new reservoir that can hold 3 million gallons of water, an important step in providing downtown San Mateo with much-needed domestic supply, fire suppression, and emergency resources. The project will begin in the third quarter of 2017 and will be completed by the end of 2018.

“This reservoir will allow Cal Water to prepare for and meet the water needs of all of our customers for generations to come,” said District Manager Ross Moilan. “By replacing the aging reservoir with a new one, we will be able to provide much-needed water supplies for the growing community.”

The existing reservoir, which is no longer in service, will be demolished to make way for the new one. The new reservoir, made from reinforced concrete, will be connected to the existing distribution network through a new ductile iron pipeline. The existing pump station at the site will continue to be used for the system’s operations.
