Wisner WWTP - Secondary Wastewater Treatment in Wisner, Nebraska

Wisner WWTP is a municipal wastewater treatment facility located in Wisner, Cuming County, Nebraska. The plant serves a population of about 1,527, reflecting its role in managing domestic wastewater for this small community in the Great Plains region. The plant provides secondary treatment, which is the standard biological treatment process required under the U.S. Clean Water Act for municipal facilities. With a designed capacity of 605.66 thousand gallons per day and an average discharge volume of 529.96 thousand gallons per day, the plant operates below its capacity, indicating adequate headroom for current demand. The treated effluent is discharged into local water bodies that ultimately drain into the Missouri River basin. This contributes to the protection of downstream aquatic ecosystems and supports the overall health of the Mississippi River watershed, which is vital for biodiversity and water supply in the central United States.

The plant discharges into tributaries of the Elkhorn River, which flows into the Platte River and then the Missouri River. This watershed supports diverse aquatic life, including fish species such as channel catfish and walleye, and provides critical habitat for migratory birds along the Central Flyway. The plant's secondary treatment helps reduce nutrient loads and protect downstream water quality.
