Olathe Lakestone Estates WWTP - Secondary Treatment in Olathe, Kansas

Olathe Lakestone Estates WWTP is a municipal wastewater treatment facility located in Olathe, Kansas, within Johnson County. The plant serves a small population of around 100 residents, reflecting its role in a localized residential area. As a secondary treatment plant, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant has a designed capacity of 45.42 cubic meters per day and currently discharges an average of 37.85 cubic meters per day. 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. The plant's secondary treatment level meets the minimum federal requirement for municipal wastewater treatment. The treated effluent from the plant ultimately drains into the Kansas River basin, which flows into the Missouri River and then the Mississippi River. This watershed supports diverse aquatic life and provides water for downstream communities. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall nutrient and pollutant load in the regional river system.

The plant discharges into the Kansas River watershed, which flows into the Missouri River and eventually the Mississippi River. This river system supports a variety of fish and wildlife, including migratory birds and freshwater mussels. The plant's secondary treatment helps reduce organic pollution, but nutrient removal may be limited, potentially contributing to downstream eutrophication in sensitive areas like the Gulf of Mexico hypoxic zone.
