The original Clinton wastewater Treatment Plant was constructed in the 1940's. The plant provided primary treatment consisting of grit removal, primary settling tanks, chlorination, sludge digestion and dewatering of sludge. In the original plant sand and other heavy inorganic solids were removed from the wastewater in the grit chamber. The effluent from the grit chamber entered the primary clarifier where suspended solids settled. The settled water was then chlorinated and discharged to the Raisin River. Settled solids from the clarifiers were digested, then dewatered on sludge drying beds prior to disposal.A new Wastewater Treatment Plant was reconstructed in 1978-80 to increase capacity and improve performance. The new wastewater treatment facility helped improve the water quality of the Raisin River. The plant’s primary treatment included an aerated grit chamber, macerator, and two primary clarifiers. The secondary phase of treatment consisted of rotating biological discs and secondary clarifiers. The wastewater was chlorinated and processed through a sand filter before being discharged. The sludge was treated with a digester before being used by local farmers as a soil conditioner.
In 2006 a new wastewater treatment plant was constructed to replace the aging 1980 plant. The current facility is an activated sludge plant with grit removal, oxidation ditches, clarifiers, cloth filters, and ultra violet disinfection. A micro strainer removed larger items from the waste stream. A grit removal system reduces the amount of sand and grit. The waste water is processed in the oxidation ditch which utilizes a biologic process to remove waste. The clarifiers help to settle out solids. The water is treated with cloth filters and disinfected with ultra violet light before being discharged to the river.Sewer Connection Fees
Residential connection fees will be charged based on the meter size required by each individual unit multiplied by the number of units. All connection fees for commercial and industrial type uses will be based on the meter size. Connection fees for water meters larger than 4 inch will be determined on a case-by case basis. All increases in meter size will be billed the difference in cost from the current size to the new size.
