Parsons selected to deliver $16 million Cemetery Brook Drain Tunnel in New Hampshire
The City of Manchester, NH has selected Parsons Corp. to deliver the new Cemetery Brook Drain Tunnel Project, the city’s largest public works project to date. The three-year, $16 million contract includes program and construction management (PM/CM) services for the project, designed to mitigate the risk of flooding in the city, eradicate combined sewer overflow (CSO) discharges into the Merrimack River, and secure the river as a source of clean drinking water.
“We are proud to leverage our engineering, water and tunnel expertise to help the City of Manchester improve water quality and community health,” said Mark Fialkowski, president, North America Infrastructure, at Parsons. “Our cutting-edge tunneling knowledge, and program and construction management capabilities have delivered underground structures including storm and wastewater tunnels that keep water moving and help deliver clean drinking water where it is needed all around the world.”
The Cemetery Brook Drain Tunnel is the centerpiece of phase two of Manchester’s more than $338 million investment to address CSOs and improve Merrimack River water quality. The new drainage system will include a tunnel, 3.2 km (2 miles) long with inside diameter of 3.6 m (12 ft), constructed 9 to 24 m (30 to 80 ft) below ground with seven drop shafts along its length to receive flows. The city will also leverage the project to upgrade utilities, rebuild roads and add curbing, sidewalks, crosswalks, bike lanes and other amenities.
Parsons is a global leader in critical infrastructure excellence, with 80 years of experience planning, designing and engineering complex tunnel projects. With more than 250 tunnels and ocean outfalls around the world, Parsons’ projects have involved challenging geologic environments, from seismically active southern California to the Chesapeake Bay’s alluvial coastal plain.
