Table Rock WWTP - Secondary Wastewater Treatment in Table Rock, Nebraska

Table Rock WWTP is a municipal wastewater treatment facility located on Houston Street in Table Rock, Pawnee County, Nebraska. Serving a small population of 397, the plant is part of the rural wastewater infrastructure in the Great Plains region of the United States. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater. With a designed capacity of 155.20 megaliters per year and an actual discharge volume of 113.56 megaliters per year, the facility operates below its capacity. The plant is regulated 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 water body, likely a tributary of the Big Nemaha River or the Missouri River basin. The plant's inland location and small service area mean its environmental impact is localized, supporting water quality in the surrounding watershed.

The plant discharges into a local stream that flows into the Big Nemaha River, which eventually drains into the Missouri River and then the Mississippi River. This watershed supports agricultural land use and provides habitat for aquatic species such as catfish and bass. The plant's secondary treatment helps protect downstream water quality in this rural, agriculturally dominated region.
