ALDA WWTP - Secondary Treatment Plant in Alda, Nebraska

ALDA WWTP is a municipal wastewater treatment facility located in Alda, Nebraska, a small community in Hall County. The plant serves a population of approximately 540 residents, reflecting its role as a small-scale treatment facility in the rural Great Plains region. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 302.83 megaliters and an annual discharge volume of 227.13 megaliters, the facility operates below its capacity, indicating room for future growth. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Nebraska Department of Environment and Energy, ensuring compliance with federal water quality standards. The treated effluent from ALDA WWTP is discharged into a local waterway that ultimately drains 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 operations help protect downstream water quality in this ecologically significant river corridor.

ALDA WWTP discharges into a receiving water body within the Platte River basin, which flows eastward to join the Missouri River near Omaha. The Platte River is a shallow, braided river that supports a unique ecosystem, including sandhill crane staging areas and endangered species like the interior least tern. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream water quality in this agriculturally influenced watershed.
