Franklin WWTF WRBP - Wastewater Treatment Plant in Franklin, New Hampshire

Franklin WWTF WRBP is a municipal wastewater treatment facility located on River Street in Franklin, New Hampshire, serving a population of about 102,784. Situated in Merrimack County, the plant is part of the state's wastewater infrastructure managed under federal and state regulations. As a large agglomeration serving over 100,000 people, the plant is subject to the US Clean Water Act and EPA NPDES permitting requirements. These regulations mandate secondary treatment as a baseline, with potential additional nutrient removal standards depending on the receiving water body's sensitivity. The plant's treatment processes and capacity are designed to meet these regulatory standards. The plant discharges treated effluent into the local watershed, which ultimately drains into the Merrimack River and then to the Atlantic Ocean. The Merrimack River supports diverse aquatic life and provides drinking water for downstream communities. The plant's operations are critical for protecting water quality in this ecologically and economically important river system.

The plant discharges into the Merrimack River watershed, which flows through New Hampshire and Massachusetts before reaching the Atlantic Ocean. The Merrimack River supports a variety of fish species, including migratory fish like Atlantic salmon and river herring, and provides habitat for freshwater mussels. Downstream, the river passes through urban and industrial areas, making nutrient and pollutant control essential for maintaining ecological health and recreational uses.
