About the Project
The existing cast iron water main was constructed over 100 years ago. The serviceable life of the pipe has come to an end. A new 12-inch ductile iron water main will be installed along Littleworth Road (NH Route 9) between Columbus Ave and the bridge over the railroad tracks, as well as along Old Littleworth Road. This will replace the existing 8” cast iron water main. New water services will be installed at each property, to the edge of the right of way. Fire hydrants will be replaced in several locations. Water service through the existing main pipe will be maintained during construction, switching to the new main pipe after connection and testing.
Paving work on Littleworth Road will include trench patches where driveways will be crossed, and larger mill & overlay sections around the intersections of Columbus Ave and Industrial Park Road across from 29 Littleworth Road. Paving work on Old Littleworth Road will be full-width repaving following subsurface utility installation.
Additionally on Old Littleworth Road, new sewer main and services will be installed where none existed prior. Services will be capped at the edge of the right of way. In accordance with RSA 147:8 all property owners with buildings within one hundred feet of the municipal sewer system shall connect to the municipal sewer system. Property owners may apply for a waiver of the mandatory connection from the Dover Utilities Commission (DUC). Additional information may be obtained by calling 603-516-6450 or emailing the project manager (contact info at the bottom of the page).
Traffic and parking restrictions
Along Littleworth Road, traffic will be reduced to one lane alternating directions, controlled by flaggers. The primary location of the new water main will be along the shoulder of the South/West sides of Littleworth Road, and driveways on this side of the highway will experience blockage for a short time as the construction crew proceeds. Ample notice will be given to residents when driveway access will be blocked.
Along Old Littleworth Road, traffic will be restricted to local residents only. Driveway access will be maintained as best as possible, and ample notice will be given to residents when driveway access will be blocked.
Notify city of bulky item trash to ensure pick up
City staff encourages residents in the construction zone who have bulky item waste (and have purchased bulky item tags) to call Community Services at 603-516-6450 before regular trash pickup. This helps the city coordinate with Waste Management and ongoing construction activities and ensure the items are picked up.
