About Us

Since 1950, the District has provided collection and conveyance of sewage waste to the San Jose/Santa Clara Water Pollution Control Plant for treatment. As a stakeholder in the watershed areas tributary to Coyote and Penitencia Creeks, our mission is to maintain the collection and conveyance infrastructure and to protect public health and the environment in an economic and efficient manner.


CSD2-3 covers approximately 15 square miles, serving a population of over 18,000 people with more than 4,500 residential and business units. The District serves nearly 4,500 users, including single family and multi-family residences, commercial businesses and industrial sites.   


The District is proactively engaged in several preventive maintenance programs aimed at reducing sewage overflows or spills.  Main sewer lines are inspected using specially designed video cameras.  Damaged or deteriorated pipes, as well as tree root intrusions, are identified for repair or replacement.  Using this video inspection method to identify necessary repairs or maintenance, the chances of stoppages in the main sewer are reduced significantly.  Additionally, the maintenance data of known trouble spots within the sewer system has been tracked in the District’s maintenance program.  Using this data, complete maintenance service can be effectively scheduled and performed throughout the sewer system at regular intervals.
