WasteWater Treatment


The first 2,000 gallons (our minimum rate*) is $15.50. Every additional 1,000 gallons used is $7.75. 


*If billing is for a partial month and consumption is minimum the bill will be prorated. This would be for the first and final bill for customers.


Built in the years of 1995-96, the wastewater treatment plant was designed to treat biological wastes using an oxidation ditch process. Other equipment includes two fine screens, two 110’ diameter clarifiers, two gravity thickeners for sludge holding, and an ultra-violet disinfection system. The plant is designed to treat an average daily flow of 6.0 million gallons per day and currently averages 4.8 million gallons a day treated flow. Wastewater is generated from the City of Madisonville and the cities of Hanson and Earlington.


Eight employees operate the treatment plant and its pretreatment program. All operators are certified by the Kentucky Division of Water. The treatment plant has received numerous operations awards including the “EPA Region IV Operations and Maintenance Excellence Award”.


The wastewater plant offers a fully approved Industrial Pretreatment program. Through the program, coordinators work with local industry to assure their effluent waste complies with EPA standards and regulations.
