Next week, the contractor will be working to tie water users into the new water main.
Monday and Tuesday, Nov. 29 and 30, work will be focused on Central Avenue between Abbey Saywer Memorial Drive and Lowell Avenue. Southbound traffic will be detoured around the project via Lowell Avenue, Mount Vernon Street and Ash Street. Northbound traffic will proceed through the work area.
Wednesday and Thursday, Dec. 1 and 2, the contractor will work between Lowell Avenue and Glenwood Avenue. Traffic will be restricted to one lane through the project area, alternated by flaggers.
On Friday, Dec. 3, the contractor will pave the week's work areas. At times, traffic will be restricted to one lane alternated by flaggers. At other times, southbound traffic will be detoured around the project area via Lowell Avenue, Mount Vernon Street and Ash Street, while northbound traffic will proceed through the work area.
Community Services Director Bill Boulanger is reaching out to residents and businesses to schedule water connections. The connections will require the water to be shut off for brief periods to individual water users when the service is connected. Contact Boulanger at 603-516-6450 or b.boulanger@dover.nh.gov.
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 in December or January, weather permitting. A complete street paving overlay is planned for 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.
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.
