Waterloo WWTP - Secondary Treatment Plant in Waterloo, Nebraska

Waterloo WWTP is a municipal wastewater treatment plant located in Waterloo, Nebraska, serving a small population of 459 residents. The facility is situated in Douglas County and plays a key role in managing local wastewater for this community. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal facilities of this scale. With a designed capacity of 189.27 thousand cubic meters per year, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Nebraska Department of Environment and Energy. The treated effluent is discharged into a local waterway that ultimately drains into the Platte River basin. This watershed supports diverse aquatic life and agricultural activities downstream. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall water quality of the regional river system.

Waterloo WWTP discharges into a tributary of the Platte River, which flows eastward into the Missouri River and eventually the Mississippi River. The Platte River basin is an ecologically significant corridor for migratory birds and supports diverse aquatic species. The plant's secondary treatment helps protect downstream water quality in this agriculturally important watershed.
