The City of Warrenton owns and operates a Multiple Loop Reactor (MLR) oxidation ditch type activated sludge plant. The plant is rated for 3.2 MGD (million gallons per day) and went online in the fall of 2004. It is currently operating at approximately 1.4 MGD.   Biosolids from the plant are treated in aerobic digesters and then land applied to surrounding agricultural ground.

A parallel sewer main installation on the east side of town ensures residents’ sewer service is adequate to meet current needs as  well as accommodate future city growth.

In 2018 the treatment plant operated at an average of 44% of the total capacity. By utilizing the sewer main flushing truck and camera system, City crews inspected and flushed approximately 93,453 feet or 28% of the system. This ongoing preventive maintenance ensures that the sewer system continues to work effectively and significantly reduces sewer back up occurrences.

Additional major infrastructure improvements including the incorporation of a parallel sewer main serving the west side of the City are planned for continued system improvement and in preparation of future City growth.
