About this project

The City of Dover is committed to proactively maintaining the municipal water system to ensure consistent high-quality water is available to those who live in, work in and visit the City. As part of the ongoing effort to replace the oldest and most at risk of failure water infrastructure, the Washington Street and Main Street Water Improvements project will target replacement of some of the oldest water distribution pipes in the Downtown area.

The project area includes all of Main Street, Washington Street from Central Avenue to Main Street and a portion of Henry Law Avenue closest to Washington Street. Replacement infrastructure includes approximately 3,000 feet of new ductile iron water main that meets the needs to today’s water systems and will provide reliable water service for the next 100+ years.

After a competitive process, the City Council at its Oct. 14, 2020 meeting, authorized the City of Dover to contract with N. Granese & Sons, Inc. of Salem, Massachusetts to complete the work. Underwood Engineers is the City’s engineering consultant who completed the design and will oversee the construction. Construction is anticipated to begin in March of 2021 and be completed in October 2021.

Due to the high vehicular and pedestrian traffic within the project area, many construction measures have been included in the design and construction contract to limit project disturbance. These measures include, temporary water services, night work, and limited construction hours. Although, these construction measures are designed to help, the area will undoubtedly experience temporary traffic congestion and service disruptions, the City asks the public for patience and understanding as we work through this critical infrastructure project.

An information meeting was held Monday Feb. 8, 2021 at 6:00 p.m. Due to the ongoing COVID-19 coronavirus pandemic, the meeting was held virtually. 

For more information or questions about the project, contact Assistant City Engineer Max Kenney, PE at m.kenney@dover.nh.com or (603) 516-1915.
