The Littleton Water Department is working with the Town of Boxborough on a project to provide safe, reliable drinking water.
Construction Update
Updated May 1st, 2025
Good Progress on Water Main Installation
Crews are simultaneously working on two water main projects:
- To carry raw water from the new Trumbull Well on Taylor Street to the Whitcomb Avenue Water Treatment Plant. Work on Whitcomb Avenue is substantially completed and the crew is now focused on installing the water main on the land parallel to Route 2.
- To carry drinking water from the Whitcomb Avenue Water Treatment Plant to an area of Boxborough where the groundwater is contaminated. This new main is completed, almost to Beaver Brook Road, off Littleton County Road in Harvard. It will then continue onto Swanson Road and end on Codman Hill Road, Boxborough.
Traffic Management
The detour around Whitcomb Avenue and Littleton County Road has been removed as the water main project has progressed onto Beaver Brook Road in Boxborough, on its way to the final destination, Codman Hill Road. We must wait at least three months to allow for settling before the final milling and curb-to-curb paving and the repairs to front lawns.Â
Crews will remain in the area completing work to prepare the water mains for service. Please use caution when driving in the area and follow the instructions of police officers.
Paving Whitcomb Avenue
Paving on Whitcomb Avenue, from Taylor Street to the town line, is scheduled to start August 11. It will be a permanent mill and overlay. Please note, we are required to wait at least three months, and sometimes longer, before applying the final layer of pavement over a trench patch to allow for settling. This reduces the potential for voids forming under the pavement which can result in potholes. We also make sure the new sewer and water mains are sealed tight and working properly so we don’t have to dig up new pavement to fix a problem.
Connection to Boxborough
Work has proceeded onto Beaver Brook Road in Boxborough and will continue onto Swanson Road and end on Codman Hill Road. This project is set to be completed by Fall 2026.
Expect roadwork Monday-Friday, 7 a.m. to 4 p.m., weather permitting. Expect rough road surfaces with metal plates or exposed gravel surfaces. Trenches are scheduled to be paved weekly or sooner in the event of inclement weather in the forecast.
Detours
LELWD has worked closely with the Police Departments from Littleton and Harvard to implement a traffic plan that minimizes the inconvenience to residents and commuters in this area, while maximizing the efficiency of work on the project. Follow the direction of the police officers on site.
