McGrew WWTP is a municipal wastewater treatment facility located in McGrew, Nebraska, a small community in Scotts Bluff County. The plant serves a population of 103, reflecting its role as a small-scale treatment system for a rural area. The plant provides secondary treatment, which is the minimum standard required under the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 56.78 units, the plant operates within its capacity to manage local wastewater flows. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Nebraska Department of Environment and Energy, ensuring compliance with effluent limits.

This river system eventually drains into the Platte River and then the Missouri River, supporting aquatic habitats and downstream water quality. The plant's operation helps protect local streams and groundwater from untreated sewage.

The treated effluent from McGrew WWTP enters a local watercourse that flows into the North Platte River, part of the Platte River basin. This watershed supports diverse aquatic life and provides critical habitat for migratory birds along the Central Flyway. The plant's secondary treatment reduces organic pollutants and suspended solids, helping maintain water quality in downstream rivers and reservoirs.
