It has a designed capacity of 151.42 cubic meters per day and discharges a similar volume, indicating full utilization. As a small plant, it operates under state-level NPDES permits administered by the New Hampshire Department of Environmental Services. The treated effluent enters the local watershed, which drains into the Connecticut River and eventually Long Island Sound. The plant helps protect the pristine headwaters region, which supports cold-water fisheries and recreational uses. Its location near Murphy Dam on the Connecticut River underscores the importance of maintaining water quality in this ecologically sensitive area.

The plant discharges into the Connecticut River headwaters, a cold-water ecosystem that supports native brook trout and other sensitive aquatic species. The river flows south through New Hampshire, Vermont, Massachusetts, and Connecticut before emptying into Long Island Sound. This watershed is a critical migratory corridor for fish and provides drinking water for downstream communities. Protecting water quality here is essential for maintaining the ecological health of the entire Connecticut River basin.
