HADAR WWTP - Secondary Treatment Plant in Hadar, Nebraska

HADAR WWTP is a municipal wastewater treatment facility located at 101 Pine Street in Hadar, Nebraska, a small community in Pierce County. The plant serves a population of 220 and operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 113.56 megaliters per year and a discharge volume matching that figure, the facility operates at full capacity. As a small-scale plant, it is subject to state-level National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body that drains into the Missouri River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting the region's surface water quality, particularly for downstream aquatic habitats and agricultural water uses common in northeastern Nebraska.

HADAR WWTP discharges into a local stream that flows into the Elkhorn River, a tributary of the Platte River, which joins the Missouri River and eventually the Mississippi River and Gulf of Mexico. The watershed supports diverse aquatic life and is an important corridor for migratory birds. The plant's secondary treatment helps reduce nutrient loading, which is critical for preventing eutrophication in downstream water bodies.
