WACO WWTP - Waco, Nebraska Wastewater Treatment Plant

WACO WWTP is a municipal wastewater treatment facility located in Waco, Nebraska, United States. The plant serves a small population of 221 residents and operates under secondary treatment standards, which is the minimum required by the US Clean Water Act for municipal wastewater. The facility is situated inland, far from coastal waters, and its treated effluent is discharged into local waterways. As a secondary treatment plant, WACO WWTP utilizes biological processes to remove organic matter and suspended solids. The plant's designed capacity is 189.27 thousand cubic meters per year, with an actual discharge volume of 75.71 thousand cubic meters per year, indicating it operates below capacity. The facility is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The plant's discharge contributes to the local watershed, which is part of the Platte River basin. The Platte River flows eastward through Nebraska and eventually joins the Missouri River, a major tributary of the Mississippi River. This river system supports diverse aquatic life and provides water for irrigation and recreation. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream ecosystems.

WACO WWTP discharges into the local watershed within the Platte River basin. The Platte River flows into the Missouri River, which then joins the Mississippi River, ultimately reaching the Gulf of Mexico. This river system supports diverse aquatic species and is an important migratory corridor for birds. The plant's secondary treatment helps mitigate nutrient pollution, which is a concern in the Mississippi River basin due to its contribution to the Gulf of Mexico hypoxic zone.
