CuSD covers approximately 15 square miles, serving a population of over 50,000 people with more than 23,000 residential and business units. the District owns and manages over 1 million lineal feet of sewer mains, 0.5 million lineal feet of sewer laterals, 17 pump stations, 4000 manholes and flushing inlets, and one equipment storage facility. CuSD conveys nearly 5 million gallons of waste-water daily from its customers for treatment at the San Jose/Santa Clara Water Pollution Control Plant.
CuSD's collection system, much of which is more than 40 years old, has been maintained proactively with regular cleaning and development of a Capital Improvement Program (CIP) aimed at improving efficiency as well as extending its useful service life.
