Woodland WWTF - Secondary Wastewater Treatment Plant in Baileyville, Maine

Woodland WWTF is a municipal wastewater treatment facility located in Baileyville, Washington County, Maine, United States. The plant serves a population of approximately 2,041 residents, providing essential sanitation services to this small community in the northeastern part of the country. The facility employs secondary treatment processes, which involve biological treatment to remove organic matter and suspended solids. With a designed capacity of 2,271.24 cubic meters per day and an average daily discharge of 946.35 cubic meters, the plant operates well within its capacity. As a US facility, it operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent from Woodland WWTF is discharged into local receiving waters that ultimately drain into the Atlantic Ocean via the St. Croix River watershed. The plant plays a crucial role in protecting downstream aquatic ecosystems, including the St. Croix River and its estuary, which support diverse fish populations and migratory birds.

The plant discharges into the St. Croix River watershed, which flows into Passamaquoddy Bay and the Bay of Fundy, a globally significant marine ecosystem known for its high tidal range and rich biodiversity. The downstream environment supports critical habitats for Atlantic salmon, alewife, and other diadromous fish species, as well as seabird colonies. The plant's secondary treatment helps reduce nutrient and pollutant loads that could otherwise impact these sensitive coastal waters.
