The Northside Wastewater Treatment Plant is located on the northwest side of the City of Hopkinsville, directly off of US Hwy 68/80, on Disposal Plant Road. This treatment plant serves the Northwest side of the City by processing pre-treated industrial and residential sewage. The plant was originally constructed in 1937 but has undergone several renovations and upgrades, some as recent as 1997. Currently the plant has a design capacity of 2.88 million gallons per day. In general terms the plant accepts this wastewater, removes 97% of all impurities, and then releases the treated water into the North Fork of the Little River which is located directly behind the plant. The plant treats or processes the wastewater in several different stages that include screening, settlement, biological digestion, filtration, chlorination, and oxidation. The solids that are present in the raw sewage are first settled out in basins called primary and secondary clarifiers. After the solids are settled out in the clarifiers, nutrients that are still present in the water are biologically digested in the trickling filters and the primary and secondary digesters. After the water has been properly filtered it is then chlorinated in order to kill bacteria that may be present. The water then travels down a series of oxidation steps that increase the oxygen content in the water to ensure that the water is habitable for aquatic life. In discussing performance of the plant, the Kentucky Division of Water requires that certain testing be completed on a daily and monthly basis in order to determine the quality of the water that is released into the North Fork. The plant does not exceed the effluent parameters and has as recent as 1995 received the Operational Excellence Award for outstanding operation from the Kentucky-Tennessee Water Environment Authority.

The Northside WWTP is a regionally approved site for septic tank disposal.
