In order to helping delivery of the new Cemetery Brook Drain Tunnel Project, which is the city’s largest public works project to date, Parsons Corporation has been selected by the City of Manchester, New Hampshire.
The three-year contract that includes program and construction management services for the project, values US$16m and is designed to help 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.
As the centrepiece of Phase II in Manchester’s more than US$338m investment, the Cemetery Brook Drain Tunnel aims to address CSOs and improve Merrimack River water quality, whereas the new drainage system will include a 3.2km-long, 3.6m internal diameter tunnel, constructed 9-24m beneath ground and is due to involve seven drop shafts along its length to receive flows.
“We are proud to leverage our engineering, water, and tunnel expertise to help the City of Manchester improve water quality and community health.Our cutting-edge tunnelling knowledge and programme 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,” said Mark Fialkowski, president, North America Infrastructure for Parsons.
Starting in central New Hampshire, the Merrimack River is the second largest river in New England and winds 188km south to the Atlantic Ocean in Newburyport, Massachusetts.
