Project overview
The Central Avenue North Water Improvements Project replaces two sections of water mains. One is a 133-year-old, 14-inch water main from Lowell Avenue to Abbey Sawyer Memorial Drive, a critical piece of Dover's water system infrastructure. The other is an undersized six-inch water main from Glenwood Avenue to Lowell Avenue installed in 1927. The contractor has replaced both mains with 16-inch ductile iron pipes expected to last the next 100-150 years. The project will significantly improve reliability and fire flow capacity in the area as well as create a better interconnection between the City of Dover's two water pressure zones.

The project is anticipated to be substantially complete this month, weather permitting. Some sewer repair work identified during the project will take place through early January. A complete street paving overlay is planned for the spring.

After a competitive bid process, the City Council awarded the construction contract to N. Granese & Sons, Inc. of Salem, Massachusetts, the same contractor as the Washington and Main Water Improvements Project.

Residents and businesses in the construction area with questions or concerns should contact Deputy Community Services Director Bill Boulanger at b.boulanger@dover.nh.gov or 516-6450. Boulanger is the project manager.
