ORCHARD WWTP - Antelope County, Nebraska Wastewater Treatment Plant

ORCHARD WWTP is a municipal wastewater treatment facility located in Antelope County, Nebraska, serving a small population of 429 residents. The plant provides secondary treatment, a standard level for communities of this size in the United States. The plant's designed capacity is 227.12 megaliters, with an annual discharge volume of 151.42 megaliters, indicating operational headroom. As a US facility, it operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES), which sets effluent limits to protect water quality. The treated effluent likely discharges to a local waterway within the Elkhorn River basin, which flows into the Platte River and ultimately the Missouri River. This watershed supports agricultural and ecological resources, making proper treatment essential for downstream water quality.

The plant's discharge enters a tributary of the Elkhorn River, part of the Platte River basin that drains into the Missouri River. This region is predominantly agricultural, and the receiving waters support aquatic life and irrigation. The secondary treatment process helps reduce organic pollutants and suspended solids, protecting the local watershed from nutrient enrichment and maintaining habitat quality for fish and invertebrates.
