Water Quality Change Effective Tuesday, Sept. 21 at 8 a.m. until Friday, Sept. 24.
Due to an emergency water leak on the water delivery system to the Rinconada Water Treatment Plant, Valley Water will shut water supply to Sunnyvale.
Sunnyvale will increase supply from San Francisco’s Hetch Hetchy Water System. And will start operating the wells to meet water demand during this week’s hot weather.
Customers along El Camino Real to the southern border of the City might experience cloudy water due to dissolved entrapped air. This is normal and expected from well operations. Once a glass is filled, the cloudiness should dissipate, and water should be clear.
Note that the water is tested and meets all federal and state requirements for safe drinking water.
