La Sierra Pipeline to Bring More Local Tap Water

March 30, 2017
Project to reduce region’s dependency on imported water

Western Municipal Water District will begin construction this spring on the La Sierra Pipeline, a $36 million project to increase local water supply. Construction is estimated to take approximately 18 months to complete and will require lane closures and some traffic disruption along La Sierra Avenue.

The pipeline project will connect two local water supply sources—the Arlington Desalter and Chino Desalter—to Western’s Riverside Retail Service Area at the La Sierra Tank. This regional reliability project will reduce Western’s dependence on costly imported water and is part of Western’s long-term reliability planning.

“The La Sierra Pipeline will help us become more self-sufficient,” said Western Municipal Water District General Manager John Rossi. “Simply put, this project is a critical step toward helping our region meet current and future water needs and further protect us from future drought impacts.”

Travel lanes may be reduced to allow for construction starting in about a month on La Sierra Avenue from El Sobrante Road to just north of Arizona Avenue. Motorists are asked to follow traffic control devices during this time.

“We understand this project will have a big impact on commuters and those who live nearby,” said Rossi. “We will do everything possible to make sure construction goes smoothly. And we hope everyone will understand the long-term benefits this project will have on our local water supply.”
