Sewer Maintenance

Sewer System repairs and upgrades are necessary to address public health and safety needs. Norwalk's sewer system is old, deteriorating and reaching the end of its anticipated lifespan. Most of Norwalk's sewer lines were constructed in the 1950's - some were constructed as early as 1935. Norwalk's sewer system includes aging clay pipes, undersized sewer mains, and other outdated infrastructure.

To ensure the health and safety of the community, the City of Norwalk established a sewer service charge in June 2013. To view the current sewer rate click here. For questions about water meter size or sewer service charge, please contact the City of Norwalk Public Services Department at (562) 929-5511.

The Sewer Maintenance section maintains over 160 miles of sewer lines, more than 2,400 manholes, and three sewer lift stations. Also provided by contract is the periodic maintenance of 91 surface drains and three wash rack sump clarifiers located at the Transportation/Public Services facility. The Section also provides 24 hour emergency response to sewer issues. The City of Norwalk Public Services Department utilizes a private contractor to clean the sewer system. Sewer lines are cleaned throughout the City on a biannual basis.

To report a sewer concern, such as a manhole overflow, spill, or odor, please contact the Public Services Department at (562) 929-5511 during regular business hours or contact the Norwalk Sheriff's Department to report after-hour emergencies at (562) 863-8711
