Londonderry public works director outlines water‑line progress and delays final paving

At a site briefing near Parental Road and Rebecca Drive, Dave Wallally, Londonderry’s director of public works, said crews have installed a major water main and will delay the road’s final top coat to avoid damage from expected construction traffic associated with the next construction phase.

Wallally said the water-line extension—installed by American Excavation Company (AEC)—begins at Paralter/Parental Road and runs north along High Range Road. He said phase one ended at Royal Circle and that phase two is planned from Royal Drive to Alexander Road. “Extension of clean drinking uh portable water that's been installed by American Excavation Company AEC,” Wallally said, naming the contractor and describing the recent work.

The project was funded in part through routing from the New Hampshire Department of Environmental Services, Wallally said. He emphasized that engineers must plan for different pressure zones and choose main sizes that will be adequate for future neighborhood connections.

Wallally described the pavement sequence the town has followed: temporary trench patches, a more permanent patch, milling to the center line, reinstalling the berm and shoulder work, then hydroseeding. He said the surface is prepared for a final top layer but the town will postpone that step. “We’re going to delay that a little bit,” Wallally said, explaining that trucks hauling materials and equipment for the next phase would otherwise “hammer and pound” a finished surface.

He framed the delay as a practical choice to protect the pavement and keep the project on schedule overall. Wallally also said the work improves public health and the environment by preventing groundwater pollution and ensuring sewer flows to a proper treatment facility. “...you'll be able to have clean drinking water in your homes,” he said.

Wallally thanked residents for their patience and cooperation and said the town expects to continue the next construction phase northward; he did not provide a firm completion date for the final pavement.

Next steps: phase two line installation is set to proceed north from Royal Drive toward Alexander Road; the town will schedule the final top coat after the heavy construction traffic for that extension has passed.
