On February 19, 2014 the Cupertino Sanitary District Board approved Resolution No. 1249 - A resolution approving guidelines for operation of the District's Sewer Lateral Program. The purpose of this program is to aid home and business owners in upgrading privately-owned sewer laterals and cleanouts within the Cupertino Sanitary District, thereby contributing to the physical, environmental and economic revitalization of the District. Please see the links below for more information.

What to Know...

Cupertino Sanitary District has been serving our community since 1956 and continues to strive toward excellent customer service while providing wastewater collection and conveyance to the City of Cupertino and areas of Saratoga.

The following links provide general information every resident should know.

Sewer Maintenance/Backup Prevention Program

In an effort to help minimize and prevent SSO's and Backups, CuSD has implemented a routine maintenance program. Routine maintenance is performed by our contractor on an annual basis by sections. This maintenance program has been effective in reducing the amount of sewer stoppages and overflows throughout the District and allows us to target problem areas.

If you repeatedly experience sewer related issues please contact our office at (408) 253-7071 and inquire about our annual maintenance program.
