After overnight work, Thursday, Dec. 2, the new water main on Central Avenue between Glenwood Avenue and Abbey Sawyer Memorial Drive is now operational.
Week of Dec. 6
The contractor will focus efforts on connecting water users to the new water main between Lowell Avenue and Glenwood Avenue.
Traffic will be a single lane through the project area, alternated by flaggers. The work area will change daily, or even multiple times a day. Motorists should anticipate lane shifts.
The week's work areas will be paved on Friday.
At the end of next week, or the beginning of the following week, work will occur on Lowell Avenue to complete the last major water main tie-in. This work is likely to disrupt traffic on Lowell Avenue but not affect Central Avenue traffic. More details will be available next week.
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.
