Canaan Valley PSD Timberline WWTP - Advanced Treatment in Davis, West Virginia

Canaan Valley PSD Timberline WWTP is a municipal wastewater treatment facility located near Davis in Tucker County, West Virginia. The plant serves a small population of approximately 895 residents, operating as part of the Canaan Valley Public Service District's infrastructure. Its location in the Appalachian region places it within a rural, mountainous setting. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the US Clean Water Act. With a designed capacity of 454.25 thousand gallons per day and an actual discharge volume of 22.71 thousand gallons per day, the facility operates well below its capacity, indicating room for future growth or seasonal demand. As a US facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the West Virginia Department of Environmental Protection. The treated effluent from the plant ultimately drains into the Potomac River basin, which flows into the Chesapeake Bay. This makes the plant's advanced treatment important for protecting downstream water quality in the Chesapeake Bay watershed, a large and ecologically significant estuary. The plant's location in a high-elevation area also contributes to the protection of local streams that support diverse aquatic life.

The plant discharges into the Potomac River basin, which flows into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed supports a rich ecosystem including blue crabs, oysters, and migratory fish. Advanced treatment at this plant helps reduce nutrient loading, which is critical for preventing algal blooms and hypoxia in the bay.
