City of Derby

Wastewater Treatment Plant

Wastewater is responsible for maintaining and servicing 588,000 feet of sewer pipe and maintaining over 2,000 manholes. Aggressive maintenance by Wastewater staff has resulted 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.

Wastewater is also responsible for the operation and maintenance of the City's Wastewater treatment facility. This facility is designed for 2.5 millions gallons of flow per day, with expansion capabilities. This modern and efficient facility historically meets or exceeds all KDHE and EPA requirements.

Two projects in the 2008 Capital Improvement Plan (CIP) for Wastewater include Phase 3 S.E. Interceptor ($5.5 million) and Bio-Solids Improvements ($3,193,000).
