Concord, NH – The New Hampshire Department of Environmental Services announced today that emergency repairs to the main sewer interceptor line along Route 11B in Gilford are ongoing and are expected to continue until September 1 or about two weeks later than initially planned. The interceptor is part of the Winnipesaukee River Basin Program’s (WRBP) sewage collection system and serves the town of Gilford. The overall collection system was constructed in 1979 and includes 12 major pump stations and 60 miles of interceptor sewers and provides treatment for over 36,500 users at its wastewater treatment facility in Franklin.
The current project involves the installation of about 960 feet of PVC pipe from Misty Harbor Resort Condominiums to Dockham Shore Road under the northerly lane of Route 11B. Approximately 85 percent of the pipe replacement work has been completed to date, with minor delays due to unforeseen service line conflicts. Barring further complications, DES anticipates that pipe replacement, clean-up and temporary paving should be completed by the end of the day on Friday, September 1 with landscape/restoration work and final paving scheduled after Labor Day.
Repairs to the line have caused minor disruption to traffic flow on Route 11B, with traffic limited to a single lane of alternating traffic during working hours (6:30 a.m. to 5 p.m.). The public is encouraged to use alternate routes to travel between the Weirs and Route 11 in Gilford, specifically via the Route 11C by-pass by the Laconia Airport.
