It serves a population of approximately 12,939 residents in the City of Saint John and surrounding areas. The plant is classified as a medium agglomeration under Canadian wastewater management frameworks. The plant operates as a lagoon-based treatment system, which is a common approach in Atlantic Canada for communities of this scale. Lagoon systems typically provide secondary treatment through natural biological processes. The plant has a designed capacity of 1.00 million liters per day, reflecting its role in managing local wastewater flows. The treated effluent from Lancaster Lagoon WWTP ultimately discharges into the Saint John River system, which flows into the Bay of Fundy. The Bay of Fundy is known for its extreme tidal ranges and supports diverse marine ecosystems, including critical fish habitats and migratory bird populations. The plant's operation is subject to provincial and federal environmental regulations to protect these sensitive downstream waters.

The plant discharges into the Saint John River watershed, which flows into the Bay of Fundy, a globally significant marine environment known for its high tidal range and productive ecosystems. The Bay of Fundy supports diverse aquatic life, including fish, crustaceans, and seabirds, and serves as an important migratory corridor. Protecting water quality in this watershed is critical for maintaining the ecological health of the downstream estuary and coastal habitats.
