Dugger WWTP - Cass, Indiana Advanced Wastewater Treatment Plant

Dugger WWTP is a municipal wastewater treatment facility located in Cass, Sullivan County, Indiana. Serving a population of 955, the plant is part of the region's infrastructure for managing domestic wastewater in a rural setting. The plant employs advanced treatment processes, exceeding the secondary treatment standard required by the US Clean Water Act. With a designed capacity of 1135.62 thousand cubic meters and an annual discharge volume of 567.81 thousand cubic meters, it operates at about 50% capacity. Such advanced treatment ensures high-quality effluent, reducing nutrient and pollutant loads. The treated effluent is discharged into local streams that drain into the Wabash River basin, ultimately reaching the Ohio River and Mississippi River. This contributes to the ecological health of downstream waters, supporting aquatic life and recreational uses in the region.

The plant's discharge enters small tributaries of the Wabash River, which flows into the Ohio River and then the Mississippi River. The Wabash River basin supports diverse aquatic ecosystems, including fish and mussel species. Advanced treatment helps protect these habitats from nutrient enrichment and contamination.
