LYTTON WWTP - Lytton, Iowa Wastewater Treatment Plant

LYTTON WWTP is a municipal wastewater treatment facility located in Lytton, Iowa, United States. The plant serves a small population of approximately 320 residents in the rural community of Garfield Township, Calhoun County. As a secondary treatment plant, it provides biological treatment to remove organic matter and suspended solids from domestic wastewater. The plant has a designed capacity of 643.52 m³/day and currently discharges an average of 227.13 m³/day of treated effluent. Under the U.S. Clean Water Act, facilities of this scale are typically regulated through the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. Secondary treatment is the minimum standard required for municipal wastewater plants in the United States. The treated wastewater from LYTTON WWTP is discharged into local surface waters that eventually drain into the Mississippi River basin. The plant plays a key role in protecting downstream water quality by reducing pollutant loads before discharge. Its operation supports the ecological health of regional streams and the larger river system.

The plant discharges into local streams that are part of the Mississippi River watershed, which ultimately flows into the Gulf of Mexico. The receiving waters support diverse aquatic life and are important for regional biodiversity. Proper treatment helps prevent nutrient enrichment and maintains water quality in downstream ecosystems.
