La Sierra Pipeline To Bring More Local Water On-Tap

Public asked to plan for traffic delays during project construction

Western Municipal Water District (WMWD) will begin construction on the La Sierra Pipeline in January, a nearly $36M project to increase local water supply. Construction is estimated to take just over 18 months to complete, and will require lane closures and some traffic disruption along La Sierra Avenue.

The pipeline project will connect the Arlington Desalter and Chino Desalter to Western's Riverside Retail Service Area at the La Sierra Tank, providing a highly reliable, local water supply for the region.

“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.”

The regional reliability project will reduce Western’s dependence on costly imported water and is part of Western’s long-term reliability planning

Travel lanes may be reduced to allow for construction starting in January 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. A public workshop will be held in November, to provide more information to those affected by the construction.

“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.”
