McCracken WWTP is a municipal wastewater treatment facility located on Ash Avenue in McCracken, Kansas, a small community in Rush County. The plant serves a population of 197, reflecting its role in a rural setting. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids, meeting typical standards for small communities in the United States. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. Facilities of this scale are typically permitted by the Kansas Department of Health and Environment. The plant's designed capacity is 132.49 thousand cubic meters per year, with an actual discharge volume of 75.71 thousand cubic meters per year, indicating it operates below capacity. The treated effluent is discharged to a local water body, likely a stream or river within the Smoky Hill River basin, which flows into the Kansas River and ultimately the Missouri River and Mississippi River. This watershed supports agricultural land use and provides habitat for aquatic species. The plant's performance is important for maintaining water quality in this semi-arid region of the Great Plains.

The plant discharges into a local watercourse that drains into the Smoky Hill River, part of the Kansas River basin. This river system supports diverse aquatic life and is used for irrigation and recreation. Downstream, the waters flow into the Missouri River and then the Mississippi River, eventually reaching the Gulf of Mexico. The region's semi-arid climate means that maintaining water quality is critical for ecosystem health and human use.
