California Water Service Infrastructure Upgrade Underway to Improve Water Supply Reliability and Fire Protection in Visalia

VISALIA, Calif.—Construction is underway on a California Water Service (Cal Water) water infrastructure project underway that will upgrade and improve water supply reliability and fire protection in Visalia.

Cal Water is adding a third water storage tank and booster station to its system, which will help augment water supply during the peak demands of summer. Construction on the 975,000-gallon tank and booster station began in November 2023 east of downtown Visalia, and is expected to be fully operational by September. So that Visalia customers experience the benefits of the new water storage tank as early as possible in summer, Cal Water will use a portable booster pump prior to completion of the booster station.

“Infrastructure improvements like this ensure that Cal Water maintains a reliable water supply for both everyday and emergency needs,” said Stephen Johnson, Cal Water’s Visalia District Manager. “It’s part of our commitment to delivering quality, service, and value to Visalia residents and businesses.”

The facility itself is located in a mostly commercial area, and the majority of the work is being performed between 7:30 a.m. and 4 p.m., Monday through Friday, with no traffic issues anticipated as a result of this project.
