Driveway access
 
The contractor has notified residents and businesses in advance when driveway access may be temporarily blocked to complete work. However, the contractor stresses that access can quickly be established when requested.

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 the City of Dover’s water system infrastructure. The other is an undersized six-inch water main from Glenwood Avenue to Lowell Avenue installed in 1927. Both mains will be replaced with 16-inch ductile iron pipes that are expected to last the next 100-150 years. The project will significantly improve reliability and fire flow capacity. The improvements will also provide better interconnection between the City’s two pressure zones, increasing the water system’s reliability throughout the City.

The project is anticipated to be substantially complete by mid to late December, weather permitting. A complete street paving overlay will occur next 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.

The project is expected to create traffic backups in and near the project area. 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.
