Lancaster Grange WWTF - Secondary Wastewater Treatment in Lancaster, New Hampshire

Lancaster Grange WWTF is a municipal wastewater treatment facility located at 46 Grange Road in Lancaster, New Hampshire, within Coos County. The plant serves a small population of 34 residents, reflecting its role in a rural community in the northern part of the state. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 15.14 units and a discharge volume matching that figure, the plant operates at full capacity. As a small facility, it is subject to state-level NPDES permitting under the authority of the New Hampshire Department of Environmental Services. The treated effluent is discharged into a local water body, likely a tributary of the Connecticut River, which flows southward through New England and eventually into Long Island Sound. The plant's operations help protect the water quality of the surrounding watershed, supporting aquatic life and downstream ecosystems.

The plant discharges into a local stream that drains into the Connecticut River basin, a major waterway in northern New England. The Connecticut River flows through New Hampshire and Vermont before reaching Long Island Sound, an estuary that supports diverse marine life and migratory fish. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting the river's ecological health and recreational uses.
