Beaver Street Interceptor
Continuing on Monday, April 15th, the dead end section of Old West Central serving Ledgewood Condominiums and Franklin Crossing will continue to be closed at Tri-County Drive. Those residents will continue to use the right-hand turn only detour onto Rt 140 by the Dunkin Donuts.
This detour will be in place Monday-Friday 7AM thru 4PM.
We appreciate the public’s continued support and understanding and will
continue to communicate regularly via social media, our dedicated email list, and the construction map below as work progresses.

History
The Beaver Street Interceptor (BSI) was originally constructed in 1914 and discharged to the former Franklin Wastewater Treatment Plant on Pond Street (aka, the sewer beds). Currently, the BSI conveys over 70% of the Town’s sewage with an average daily flow (ADF) of approximately 1.5 million gallons per day (MGD) of sewage flow through the pipeline. The interceptor includes 59 manholes and approximately 2.3 miles (11,932 LF) of 16-inch to 24-inch cast iron (CI) pipe, reinforced concrete (RC) pipe, and vitrified clay (VC) pipe. The BSI extends from the intersection of Cottage Street and Union Street to the easement behind Pond Street, near the Interstate 495/Route 140 interchange, where it discharges to the Mine Brook Interceptor. Due to its age, the risk and consequence of failure, and the percentage of the Town’s sewer flows conveyed by the interceptor, the BSI is considered Franklin’s most critical sewer asset.
The BSI, constructed in 1914, has been in continuous service for 108 years. Other than routine maintenance, no improvements to the interceptor have been made since its construction. Since 2003, the Town has contracted for cleaning, internal investigation, and condition assessment of the BSI on a recurring 5-year basis. Extensive manhole inspections and cleaning and closed-circuit television (CCTV) inspection of the pipes were last completed in 2013 and 2014, respectively. Results of these investigations have shown signs of increasing deterioration and worsening conditions of the pipes and manholes, most notably increased tuberculation, cracks, manhole and pipeline infiltration, and root intrusion.
Rehabilitation/Repair Project Description
The Project is located in the Town of Franklin, MA in Norfolk County. The current interceptor is in need of replacement. Therefore, the Town proposes rehabilitation, replacement, and general improvements to the interceptor as well as a new pump station on the property at 275 Beaver Street, Franklin, MA. The proposed project provides the most cost-effective, long-term solution to the BSI’s capacity and structural deficiencies, human health and environmental risks, accessibility and operation and maintenance challenges, by abandoning and rerouting sewers in the most risk-prone and problematic, inaccessible areas. The work of the Project to reroute sewers is being undertaken, in part, to move sewers out of wetland resource areas at the same time as making other improvements.
The Project includes the following key components:
- New 6 MGD Beaver Street Pump Station and 4,000 LF of 18-inch Force Main from the pump station to discharge at Pond Street.
- Rehabilitation of 6,100 LF of BSI using Cured in Place Pipe Lining (CIPPL)
- Installation of 6,000 LF of new gravity sewers
- The work will take place at 5 MBTA/Keolis Railroad Crossings including 3 pipe replacements using jack and bore technique and 2 pipe rehabilitation locations using CIPPL.
- Abandonment of BSI from Panther Way to Franklin Village Plaza and Route 495 crossing
