The division ensures smooth and safe day to day operations of the Wastewater Treatment Plant and associated 69 pump and lift stations, and nearly 40 miles of various diameter sewer pipes. The Division projects future requirements and plans for their implementations. Future system plans can be viewed by reviewing the Long Range Wastewater Master Plan (LRWMP) that can be accessed by clicking the link below:
The Wastewater Division is also responsible for control over the budget for the Kent County Wastewater Facilities.

Description of Kent County Wastewater Treatment Facility
The Kent County Regional Wastewater Treatment Plant is a secondary waste treatment facility that receives wastewater from Kent County, southern portions of New Castle County and northern portions of Sussex County. The treated wastewater is then discharged to a tributary to the Murderkill River referred to as "The Gut."
The treatment system is represented by the diagram below. In the process, wastewater enters the plant and is screened for large objects. Next grit, such as sand and gravel, is removed in a grit removal system. Biological treatment occurs in two parallel aeration basins that can provide nutrient removal, using a patented process developed by Parkson Corp. and referred to as the Bio-Lac process. The wastewater is then chlorinated in a chlorine contact chamber, and then residual chlorine is removed by the addition of sulfur dioxide. A schematic diagram of the wastewater system can be seen by clicking on the link below:
Biosolids are removed and recirculated through four secondary clarifiers. The biosolids that are wasted are thickened in four aerobic sludge digesters, and then treated in a process operated by K-F Technologies which includes lime stabilization after being dewatered on two belt filter presses. Biosolids are then heat treated to remove additional moisture, and then the resulting material identified as Kentorganite is land applied to County-owned and other local farms in the area.
