Main Sewer Line Repairs Scheduled In Gilford
Traffic Delays Expected on Route 11B from July 17 to August 18
DATE: July 10, 2006

Concord, NH – The New Hampshire Department of Environmental Services announced today that emergency repairs to a problematic main sewer interceptor in Gilford have been scheduled to begin on July 17 and are expected to continue until August 18. This interceptor is part of the Winnipesaukee River Basin Program’s (WRBP) sewage collection system, which serves ten communities in the Lakes Region. The 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 most recent sewer leak occurred on May 28 and 29, and involved the repair of a three-inch hole in the 24-inch ductile iron line. A 2,000-foot length of force main lying west of the Gilford pump station has been the subject of a number of repairs since 1992 due to external corrosion from aggressive soils. The current project will involve the installation of 960 feet of PVC pipe from Misty Harbor Resort Condominiums to Dockham Shore Road under the northerly lane of Route 11B.

Project notification has been provided to the abutters, NHDOT, and Gilford officials. Barring unforeseen complications, DES anticipates that pipe replacement and clean-up should be completed by the end of the day on Friday, August 18, except for final paving, which is expected to occur sometime after Labor Day.

Repairs to the line are likely to cause disruption to traffic flow on Route 11B. During the course of the project, Route 11B will be limited to a single lane of alternating traffic during working hours (6:30 a.m. to 5 p.m.). The road will be reopened to two-way traffic during non-working hours (evenings and weekends). The public is asked 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. Signs will be posted to encourage this alternate route.

WRBP staff and its engineer, SEA Consultants, will work very closely with James S. Piscopo General Contractor to ensure that vehicular and pedestrian access to Lake Winnipesaukee and area businesses is maintained and to minimize the level of inconvenience to people from this activity.
