Overview
Greenwood WWTF is a secondary treatment plant serving 100 people in Saint John, New Brunswick, Canada. It discharges treated wastewater near the Bay of Fundy coast.
Greenwood WWTF is a municipal wastewater treatment facility located in the Greenwood area of Saint John, New Brunswick, Canada. The plant serves a small population of 100 residents and operates under secondary treatment standards, which is typical for small communities in the region. As a secondary treatment plant, Greenwood WWTF uses biological processes to reduce organic matter and suspended solids before discharge. The plant's operational status is active, and it handles a daily discharge volume of 45 cubic meters. Secondary treatment aligns with Canadian federal guidelines for wastewater systems serving small populations. The plant's proximity to the coast (within 10 km) means its effluent enters a watershed that drains into the Bay of Fundy, a globally significant marine ecosystem known for its high tides and rich biodiversity. The receiving water body supports fisheries and migratory bird habitats, making effective treatment important for environmental protection.
Environmental context
Greenwood WWTF discharges into a local watercourse that flows toward the Bay of Fundy, a major Atlantic inlet between New Brunswick and Nova Scotia. The Bay of Fundy is ecologically sensitive due to its extreme tidal ranges, which support unique intertidal habitats and important fisheries, including Atlantic salmon and herring. The plant's secondary treatment helps reduce nutrient and pollutant loads entering this dynamic coastal environment.
