The Rinconada Water Treatment Plant is the second-largest of the Santa Clara Valley Water District's plants. Completed in 1967 by the Santa Clara County Flood Control and Water Conservation District - the precursor to today's water district - the plant can treat and deliver up to 80 million gallons of water each day for retailers who supply residential and commercial users in the West Valley, including the cities of Santa Clara, Campbell, Sunnyvale, Cupertino, Mountain View, Monte Sereno, Saratoga and Los Altos and the towns of Los Gatos and Los Altos Hills.
Rinconada draws water from the South Bay Aqueduct (SBA) and the San Luis Reservoir. The San Luis Reservoir is a key component of the federal Central Valley Project while the SBA is a key component of the State Water Project system. Water from the Sacramento-San Joaquin Delta pumps into the Delta-Mendota Canal and then into the San Luis Reservoir. The water district is one of many users that draw water from this reservoir. The water district's local Anderson and Calero reservoirs can also supply the plant.
The Reliability Improvement Project
Making the plant

In 2015, the water district began a large scale modernization of the facility, work that is overhauling the water treatment process in order to secure the plant's reliability as a drinking water provider.
This endeavor is replacing or upgrading all major plant components and will increase Rinconada's treatment capacity to 100 million gallons of water a day. The work will also help the water district meet increasingly stringent standards for water quality, seismic stability and safety. The work is scheduled for completion in 2019.
The water district has imposed traffic restriction on the project's contractors. The project has different types of trucks on the project, with different hours depending on their function. Hauling trucks, for example, which concentrate on soil and off dirt hauling, are restricted to operating from 9 a.m. to 4 p.m. All other trucks, including concrete ready mix trucks, can operate from 8 a.m. to 5 p.m. All truck traffic must use the truck route approved by the town of Los Gatos, which runs from Winchester Boulevard to Knowles Drive to Pollard Drive to More Avenue to Granada Way.
It's important to remember that the water treatment plant also has other projects taking place, with trucks associated with that work that are not bound by the restrictions for the Reliability Improvement Project. Other projects at the plant include work to improve the way the facility handles sludge produced during the treatment process. Known as the Treated Water Valves Upgrade/Residuals Management Project, the district expects construction to continue through 2015.
