Sewer services


The City’s Public Works Agency is responsible for maintaining the citywide water and sewer system. The agency serves a population of 330,920 people and is responsible for maintaining 390 miles of sewer main, 7,000 sewer manholes, two sewage lift stations, and two force mains.

The majority of the City’s sewer mains range from 6” - 12” in diameter, with several as large as 21” in diameter, the majority of which is proactively cleaned on an annual basis. Additionally, the City provides customer service, identifies illegal connections to the sewer system, and addresses sewer blockages. The City is not responsible for maintaining the 46,000 private sewer laterals. However, the City does offer complimentary repairs for sewer laterals.
