Construction Notification - Third Street Water & Drainage Improvements

May 22, 2023
The Ayer Department of Public Works (DPW) and its Contractor, CHB Excavating, will be replacing underground water and drainage infrastructure on Third Street. Work is planned to start as soon as Tuesday, May 30th and is anticipated to be complete by the end of this summer.
The project includes replacement of water mains, hydrants, valves, drainage pipe, and catch basins. Water services for homes on Third Street will be replaced from the new water main to the home’s property line.
Homes on Third Street will be connected to a temporary above-ground water main during the duration of water main replacement. The temporary water main will be installed just off the edge of the road. The temporary water main will be buried in shallow trenches or installed at grade and covered for a proper ramp across driveways.

Temporary interruptions of water service may be required. DPW will deliver notices to any effected residence at least 48 hours prior to any planned interruption of water service.

Third Street will remain open to local traffic and to public safety vehicles.

Trenches will be temporarily covered with steel plates and repaved at minimum once per week.

Ayer DPW plans to resurface Third Street (full width and length) in 2024.

Work hours are limited to 7AM – 4PM, Monday through Friday. Ayer DPW will be on site inspecting the work. If you have questions, please call DPW at 978-772-8240 (7:30 to 3:30) or email
