Holdrege WWTP - Phelps County, Nebraska Wastewater Treatment Plant

Holdrege WWTP is a municipal wastewater treatment facility located on South Brewster Road in Phelps County, Nebraska, serving a population of about 5,636. The plant is situated in the central United States, within the Platte River basin, and operates as part of the region's water infrastructure. As a small-to-medium agglomeration, the facility is subject to US EPA National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits based on the receiving water body's designated uses. Under the Clean Water Act, plants of this scale are typically required to provide secondary treatment as a minimum standard. The treatment process at Holdrege WWTP is designed to meet these federal and state requirements, ensuring that discharged water does not impair the quality of local streams or rivers. The facility's operational capacity and treatment details are managed by the local municipality to comply with Nebraska Department of Environment and Energy regulations. The treated effluent from Holdrege WWTP ultimately flows into the Platte River system, which drains eastward into the Missouri River and then the Mississippi River. This watershed supports diverse aquatic life and provides water for agricultural and municipal uses downstream. The plant's discharge is regulated to protect these ecological and human uses, maintaining water quality standards in the region.

Holdrege WWTP discharges into the Platte River basin, a major tributary of the Missouri River. The Platte River is a critical habitat for migratory birds, including the endangered whooping crane, and supports diverse fish species. The treated effluent contributes to the river's flow, especially during dry periods, and must meet nutrient and pathogen limits to prevent algal blooms and protect downstream ecosystems. The watershed ultimately drains to the Gulf of Mexico via the Mississippi River, linking local water quality to broader regional concerns.
