WASTEWATER OPERATIONS
DESCRIPTION / MISSION
Public Works Wastewater Operations Division is responsible for providing the city’s 18.2 square mile service area with a safe,
reliable system for the collection and disposal of wastewater. The wastewater collection system is comprised of approximately 292
miles of various size lines. The collection system also has approximately 5,188 manholes and 2 mechanical lift stations. Our
mission involves a commitment to maintaining a superior wastewater service that focuses on the interest of the city, the citizens it
serves, and the protection of the environment. Comprehensive training, constant monitoring and assessment of the collection
system provide for an efficient and accountable operation. In addition, newly developed standards and technologies are routinely
explored for cost effectiveness and improved service.
