Linwood Septic Tanks Wastewater Treatment Plant, Linwood, Nebraska

Linwood Septic Tanks is a municipal wastewater treatment facility located in Linwood, Nebraska, a small community in Butler County. The plant serves a population of 118 residents, reflecting its role as a small-scale treatment system for the local area. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. With a designed capacity of 37.85 cubic meters per day and a discharge volume matching that figure, the facility operates at full capacity. As a US plant, it falls under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permitting program, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body 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 small scale and inland location reduce its environmental footprint compared to larger coastal facilities.

The plant discharges into a local waterway that flows into the Platte River basin, which drains into the Missouri River and eventually the Mississippi River. The Platte River is a vital ecosystem supporting fish species like channel catfish and pallid sturgeon, and it serves as a key stopover for sandhill cranes during migration. The plant's secondary treatment helps protect these downstream habitats from nutrient and pathogen pollution.
