The Water & Wastewater Board began construction of the first wastewater treatment plant for the City of Madison in August 2001. This facility was placed into service in February 2003; marking the first time in the history of Madison that the city provided Board controlled sewage treatment for its citizens.
Our wastewater system consists of the Madison Wastewater Treatment Plant, 20 pump stations, and 250 miles of mains serving 10,200 customers. The pump stations range in size from 100 gallons per minute to 18,000 gallons per minute. The wastewater treatment plant utilizes an activated sludge process and the treatment process consists of screening, grit removal, aeration, clarification, aerobic digestion and disinfection with the treated effluent diffused into the Tennessee River.
All biosolids generated by the treatment process are submitted to an aerobic digestion process reducing pathogens and vector attraction properties within EPA approved levels. After meeting strict requirements, these treated biosolids are then applied to pasture and cropland as fertilizer at no cost to the landowner.
The wastewater treatment plant is staffed by personnel certified by the Alabama Department of Environmental Management as Wastewater Treatment Plant operators having passed service, educational and testing requirements to meet ADEM standards.
The wastewater discharged from the treatment plant is tested according to ADEM standards and must meet treatment limits for total suspended solids, carbonaceous biochemical oxygen demand, pH, fecal coliform, ammonia and toxicity. This testing is performed by plant operators on site and by a private laboratory.
