MCLEAN WWTP - Secondary Treatment Plant in Pierce County, Nebraska

MCLEAN WWTP is a municipal wastewater treatment facility located in Pierce County, Nebraska, United States. The plant serves a small population of 38 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all wastewater discharges. For small facilities like this, permits typically specify effluent limits based on secondary treatment standards. The plant's designed capacity is 18.93 units, and it discharges a similar volume daily, indicating full utilization. The treated effluent is discharged into a local water body, likely a stream or river in the Elkhorn River basin, which flows into the Platte River and eventually the Missouri River. This watershed supports agricultural activities and provides habitat for aquatic species. Proper treatment helps protect downstream water quality in this region of the Great Plains.

The plant discharges into a local water body within the Elkhorn River basin, which drains into the Platte River and then the Missouri River. This watershed is part of the Mississippi River system, ultimately reaching the Gulf of Mexico. The area is primarily agricultural, and the plant's secondary treatment helps reduce nutrient loading that could contribute to downstream eutrophication. The receiving waters support diverse aquatic life and are used for irrigation and recreation.
