The Cemetery Brook Drain Tunnel Project in Manchester, New Hampshire, is a cornerstone of the city’s efforts to enhance stormwater management and protect the Merrimack River. Part of the Phase II Combined Sewer Overflow (CSO) Program, this 11,700-foot tunnel, built 30 to 80 feet below the surface, is designed to reduce 75% of combined sewer overflows into the Merrimack River. This ambitious project not only improves water quality for the over 600,000 residents who rely on the river for drinking water but also plays a key role in revitalizing downtown Manchester.
Once completed, the Cemetery Brook Drain Tunnel will significantly mitigate street flooding, reduce pollution, and integrate green infrastructure into the city’s stormwater management system, underscoring the vital role of modern engineering in urban renewal and environmental protection.
