Londonderry public works director outlines NH‑DES funded water‑main extension to bring clean drinking water to neighborhood
Summary
Dave Wallally, Londonderry director of public works, described a New Hampshire Department of Environmental Services–funded project to extend a 12‑inch ductile‑iron water main along South Road toward Chase Road to serve a neighborhood with a history of contamination; final paving is expected in fall 2027.
Dave Wallally, director of public works for the Town of Londonderry, described on‑site work to extend a 12‑inch ductile‑iron water main along South Road near Pleasant Drive toward Chase Road, saying the project will bring safe drinking water to an area that has experienced contamination for many years.
"This is an exciting project to finally get some safe clean drinking water into the area where residents have been earning for it for quite some time," Wallally said, describing excavation, backfilling and temporary trench patching currently visible at the site.
Wallally said crews are installing the pipe inside a trench box, backfilling and compacting in stages. He explained that the current trench patch extends to about the center of the lane and that crews will return with a milling machine to widen and smooth the patched area, place a leveling course and then apply a full overlay to both sides of the road when construction is complete.
The director gave the project's estimated completion as "fall of 2027," saying that final work will include paving, shoulder repairs, vegetation restoration and other punch‑list items. Wallally also noted the contract is funded through the New Hampshire Department of Environmental Services.
On logistics, Wallally pointed to a laydown area across the street used to store materials, construction trailers and pipe. He said the contractor reached an agreement with the Ponderosa mobile home trailer park for that staging area, which is often hard to find in dense residential neighborhoods.
"We're right in the thick of it here so hard hats on for safety and everybody's doing a good job at controlling the traffic," Wallally said, thanking residents for their cooperation and reiterating the project's aim to deliver safe, clean drinking water to the town.
Crews will continue trenching, compaction and trench patching in the short term and are scheduled to return with milling and final paving as the project progresses toward the stated fall 2027 completion date.
