Humphrey WWTP is a municipal wastewater treatment facility located on State Highway 91 in Platte County, Nebraska. The plant serves a small community of approximately 816 residents, reflecting its role in rural wastewater management in the central United States. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal facilities. With a designed capacity of 529.96 volume units and a current discharge volume of 454.25, the plant operates within its capacity. As a US facility, it operates under an EPA National Pollutant Discharge Elimination System (NPDES) permit, which sets effluent limits to protect water quality. The treated effluent is discharged into a local receiving water body, which ultimately drains into the Platte River basin. The Platte River is a major tributary of the Missouri River, supporting diverse aquatic life and providing water for irrigation and recreation in the region. The plant's operations help maintain the ecological health of this important watershed.

The plant discharges into a local waterway that flows into the Platte River, a key river in Nebraska that drains into the Missouri River and eventually the Mississippi River. The Platte River basin supports a variety of wildlife, including migratory birds along the Central Flyway, and its water quality is critical for downstream ecosystems and human uses.
