Basin E Wastewater Treatment Plant, Corner Brook, Newfoundland and Labrador

Basin E is a municipal wastewater treatment facility located on Griffin Drive in Corner Brook, Newfoundland and Labrador, Canada. The plant serves a small population of 267 residents and operates under secondary treatment, which is the standard for communities of this size in Canada. The plant's treatment process provides secondary treatment, which typically involves biological treatment to remove organic matter and suspended solids. As a small-scale facility, it operates under provincial regulations that align with the Canadian Council of Ministers of the Environment (CCME) guidelines for wastewater systems. The treated effluent from Basin E is discharged into the local watershed, which ultimately drains into the Gulf of St. Lawrence. This coastal discharge point is within 10 km of the Atlantic Ocean, making the plant's operations significant for protecting the marine environment. The receiving waters support diverse aquatic life and are important for local fisheries and tourism.

Basin E discharges treated wastewater into the Corner Brook area, which drains into the Humber River estuary and then into the Bay of Islands, a deep fjord-like inlet on the west coast of Newfoundland. The Bay of Islands opens into the Gulf of St. Lawrence, a critical marine ecosystem supporting fish stocks, seabirds, and marine mammals. The plant's coastal proximity means its secondary treatment helps reduce nutrient and pathogen loads to protect this sensitive marine environment.
