City of Derby

Wastewater Treatment Plant

Wastewater is responsible for maintaining and servicing 118 miles of sanitary sewer pipe and maintaining nearly 2,800 manholes and 636,000 of sewer pipe.

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.

Projects included in the Capital Improvement Plan (CIP) for Wastewater include Phase 3 of the Southeast Interceptor ($4.5 million), Bio-Solids Improvements ($3.2 million), and Nutrient Removal Requirements ($4 million).
