With a population served of 165, this facility is part of the rural wastewater infrastructure in York County. The plant is situated inland, away from coastal areas, and operates under Canadian provincial regulations. The plant provides secondary treatment, which is a standard biological treatment process that removes organic matter and suspended solids. For a small agglomeration of this size, secondary treatment meets the typical requirements under Canadian wastewater regulations. The treated effluent from this plant is discharged into local water bodies within the Nashwaak River watershed, which flows into the Saint John River and eventually into the Bay of Fundy. The Bay of Fundy is known for its high tidal range and supports diverse marine life, including migratory fish species. The plant's operation helps protect downstream water quality in this ecologically significant region.

The Lagoon plant discharges into the Nashwaak River watershed, a tributary of the Saint John River. The Saint John River flows into the Bay of Fundy, a globally significant estuary known for its extreme tides and rich biodiversity. The receiving waters support Atlantic salmon, brook trout, and other aquatic species. The plant's secondary treatment helps reduce nutrient and organic loading, protecting downstream habitats from eutrophication and maintaining water quality for recreational and ecological uses.
