Jarvis Sewage Lagoons discharges into the Lake Erie watershed, which drains into the Great Lakes system and eventually the Atlantic Ocean via the St. Lawrence River. Lake Erie is ecologically sensitive, supporting fish spawning grounds and migratory birds. The plant's proximity to the coast means its effluent can affect nearshore habitats, including wetlands and beaches, which are important for biodiversity and recreation.
