Vermillion WWTP - Secondary Wastewater Treatment in Vermillion, Kansas

Vermillion WWTP is a municipal wastewater treatment facility located on Stone Road in Vermillion, Marshall County, Kansas. The plant serves a small population of 97 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater. With a designed capacity of 79.49 million gallons per year and an actual discharge volume of 37.85 million gallons per year, the plant operates well below its capacity. This suggests adequate headroom for current and future demand. The treated effluent is discharged into a local waterway that ultimately drains into the Big Blue River basin, part of the Kansas River watershed. This region supports agricultural activities and provides habitat for aquatic species. Proper treatment helps protect downstream water quality and ecosystem health.

The plant discharges into a tributary of the Big Blue River, which flows into the Kansas River and eventually the Missouri River. This watershed supports diverse aquatic life and is important for regional agriculture. The secondary treatment process reduces nutrient and organic loads, helping to maintain water quality in downstream ecosystems.
