Our experience in managing challenging subsurface conditions, such as mixed-face transitions and soft ground below the water table, ensures that tunnels are constructed with safety and efficiency in mind. Utilizing advanced techniques like pressurized-face tunneling, we are equipped to address the difficult ground conditions often encountered in large-scale stormwater management projects.

Our team of design engineers are available to tackle diverse projects. The Cemetery Brook Drain Tunnel will not only improve water quality in the Merrimack River but also support urban revitalization by upgrading subsurface infrastructure, improving streets, and incorporating green designs for stormwater management.

Stiver Engineering delivers tailored solutions for infrastructure development, structural design, and more. From concept to completion, we bring our expertise to civil and structural engineering projects of all sizes. With a strong commitment to quality, safety, and innovation, Stiver Engineering ensures that each project is designed and executed to meet the highest standards in the industry.

Infrastructure: The City of Manchester, NH

Enhancing Water Quality in Manchester, NH with the Cemetery Brook Drain Tunnel Project

The Cemetery Brook Drain Tunnel Project, an ambitious public works initiative dedicated to improving water quality in the Merrimack River. As part of the Phase II Combined Sewer Overflow (CSO) Program, this project is crucial for mitigating stormwater overflows, reducing street flooding, and protecting both the environment and the community.

The Cemetery Brook Drain Tunnel will be an 11,700-ft long, large-diameter stormwater conveyance tunnel, constructed between 30 to 80 feet beneath downtown Manchester. The tunnel will reduce 75% of CSO discharges into the Merrimack River, ensuring cleaner water for over 600,000 residents who depend on the river for their drinking water.

By preventing combined sewer overflows, this project will play a key role in protecting the environment and ensuring clean water for Manchester’s residents. In addition to improving the city’s stormwater infrastructure, it will also contribute to the revitalization of downtown Manchester, incorporating sustainable designs and improving public spaces for future generations.
