Gosper Co Johnson Lake Wastewater Treatment Plant, Nebraska

Gosper Co Johnson Lake is a wastewater treatment plant located on Road 748 in Gosper County, Nebraska, United States. The facility serves a population of approximately 2,100 residents in the rural area. It operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides advanced treatment, which goes beyond secondary treatment to remove additional nutrients and contaminants. It has a designed capacity of 832.79 m³/day and currently discharges 378.54 m³/day of treated effluent. The plant's treatment process is designed to meet stringent water quality standards typical for facilities in sensitive watersheds. The treated effluent is discharged into local water bodies that drain into the Platte River basin, a major tributary of the Missouri River system. The downstream environment supports diverse aquatic life and provides habitat for migratory birds. The plant's advanced treatment helps protect water quality in this agriculturally important region.

The plant discharges into local streams that flow into the Platte River, a key tributary of the Missouri River. The Platte River basin is an ecologically significant corridor for migratory birds, including sandhill cranes, and supports diverse fish populations. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality in the Missouri River and ultimately the Gulf of Mexico.
