Blue Hill WWTP - Secondary Treatment Plant in Webster County, Nebraska

Blue Hill WWTP is a municipal wastewater treatment facility located in Webster County, Nebraska, serving a small population of 918 residents. The plant operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal wastewater discharges. As a small-scale facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Nebraska Department of Environment and Energy, ensuring compliance with water quality standards. The plant employs secondary treatment, a biological process that removes organic matter and suspended solids from wastewater. With a designed capacity of 378.54 units and an average daily discharge of 340.69 units, the facility operates at approximately 90% capacity, indicating efficient utilization. The treatment process meets the standard requirements for secondary treatment under US EPA regulations, which mandate at least 85% removal of biochemical oxygen demand and total suspended solids. The treated effluent is discharged into local waterways that ultimately drain into the Platte River basin, a major tributary of the Missouri River. The Platte River system supports diverse aquatic life and provides critical habitat for migratory birds along the Central Flyway. The plant's discharge contributes to the overall water quality management in the region, helping to protect downstream ecosystems and recreational uses.

The treated effluent from Blue Hill WWTP enters local streams that flow into the Platte River, a key tributary of the Missouri River. The Platte River basin supports a variety of fish species and provides essential stopover habitat for migratory waterfowl and shorebirds. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, mitigating potential impacts on downstream water quality and aquatic ecosystems in this agriculturally dominated region.
