California Water Service has begun two major infrastructure projects in Sunnyvale and Los Altos aimed at improving water reliability and fire protection, Cal Water officials said.
Crews are installing about 8,590 feet — roughly 1.6 miles — of new water main across both projects, along with dozens of new service connections and fire hydrants, Cal Water noted.
In Sunnyvale, work includes 3,390 feet of new main along Carlisle Way and nearby streets, replacing older 4-inch pipes with larger 8-inch and 12-inch mains.
Meanwhile, in Los Altos, crews are installing 5,200 feet of upgraded main along Grant Road, replacing 10-inch pipes with 12-inch lines to increase water flow.
The projects, located near Panama Park in Sunnyvale and near Oak Avenue Elementary and Mountain View High School in Los Altos, are expected to be completed by the end of July, according to a news release.
Construction is scheduled on weekdays, with traffic controls in place to minimize disruptions. Temporary paving will be installed until permanent road repairs are completed following construction.
