MARSHALL CO SD SENTIMENTAL WWTP - Zitko Terrace, West Virginia Wastewater Treatment

MARSHALL CO SD SENTIMENTAL WWTP is a municipal wastewater treatment facility located in Zitko Terrace, Marshall County, West Virginia. The plant serves a small population of 120 residents and operates under secondary treatment standards, which involve biological processes to remove organic matter and suspended solids. With a designed capacity of 60.57 megaliters per year and an annual discharge volume of 45.43 megaliters, the facility operates at a utilization rate of approximately 75 percent. The plant's secondary treatment level meets the requirements of the U.S. Clean Water Act, which mandates secondary treatment for municipal wastewater plants. As a small facility serving fewer than 10,000 people, it is subject to EPA NPDES permitting through the state of West Virginia, ensuring compliance with effluent limits for biochemical oxygen demand and total suspended solids. The treated effluent is discharged into local waterways that drain into the Ohio River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a role in protecting water quality in the Ohio River watershed, which supports diverse aquatic life and provides drinking water for downstream communities.

The plant discharges into tributaries of the Ohio River, which flows into the Mississippi River and then the Gulf of Mexico. The Ohio River watershed supports a variety of fish species and is an important migratory corridor for birds. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream aquatic ecosystems and recreational uses.
