Harder water in store for Cal Water users

California Water Service Company (Cal Water) customers in Los Altos, Mountain View, Los Altos Hills and Sunnyvale may experience harder water than usual from Jan. 27 through Feb. 6, due to a Santa Clara Valley Water District (SCVWD) repair project.

Water hardness is not a health issue, Cal Water officials said, and the water will continue to meet all water quality standards during this period.

While repairs are underway, Cal Water will supplement reduced imported water supplies from SCVWD with local groundwater, which is typically harder because it contains more naturally occurring minerals such as calcium and magnesium.  Although the water hardness poses no health concern, it can affect the taste, odor, and color of the water; inhibit the water’s ability to create soap lather; and cause a white build-up on glassware, dishes and plumbing fixtures.  

Customers can prevent spotting on dishes and silverware by washing and drying them by hand or drying them immediately after they are washed in the dishwasher.  Spots can be removed with white vinegar.


Cal Water serves about 67,500 people through 18,400 service connections in Los Altos and parts of Cupertino, Los Altos Hills, Mountain View, and Sunnyvale. The company has provided water service in the area since 1931.  For more information, visit calwater.com.
