Washington Co Stacy Meadowcrest Subdivision WWTP and Sewers - Marietta, Ohio Advanced Treatment Facility

Washington Co Stacy Meadowcrest Subdivision WWTP and Sewers is a municipal wastewater treatment facility located in Marietta, Ohio, within Washington County. The plant serves a small population of 255 residents, reflecting its role in a suburban subdivision setting. As part of the United States' wastewater infrastructure, it operates under the Clean Water Act, which governs discharge standards through the National Pollutant Discharge Elimination System (NPDES) permitting program. The facility employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 124.92 units and a current discharge volume of 102.21 units, the plant operates below its maximum capacity, indicating room for future growth. The advanced treatment level aligns with EPA expectations for protecting sensitive water bodies, even for small communities. The treated effluent is discharged into a local waterway that ultimately drains into the Ohio River, a major tributary of the Mississippi River. This downstream connection underscores the plant's role in maintaining water quality in the Ohio River basin, which supports diverse aquatic life and provides drinking water for millions. The plant's advanced treatment helps minimize nutrient and pollutant loads to this critical watershed.

The plant discharges into a local stream that flows into the Ohio River, a major tributary of the Mississippi River. The Ohio River basin supports diverse aquatic ecosystems, including fish species such as bass and catfish, and provides habitat for migratory birds. The advanced treatment level helps protect downstream water quality, reducing the risk of eutrophication and maintaining ecological balance in the river system.
