Help Center
The Wastewater Division is responsible for maintaining and servicing 127 miles of sanitary sewer pipe and 2,839 manholes. Aggressive maintenance by wastewater staff results in several benefits to Derby residents.
  • Citizens experience very few blockages and flooding, and Derby's insurer considers Derby a low risk, which keeps premiums lower.
  • The entire sewer main collection system has been mapped by GIS, which allows staff to identify the history of all pieces of the sewer collection system.

Treatment Facility
Wastewater is also responsible for the operation and maintenance of the city's treatment facility. This facility is designed for 2.5 millions gallons of flow per day, with expansion capabilities to handle flows well into the future. The facility is authorized to discharge under the National Pollutant Discharge Elimination System and meets or exceeds all Kansas Department of Health and Environment and/or Environmental Protection Agency requirements.
