Winnipesaukee River Basin Program (WRBP)

State-owned sewer system serving portions of the New Hampshire Lakes Region.

The Winnipesaukee River Basin Program (WRBP) is the state-owned sewer system serving portions of the New Hampshire Lakes Region communities of Center Harbor, Moultonborough, Gilford, Meredith, Laconia, Belmont, Sanbornton, Northfield, Tilton and Franklin.

The WRBP's highly-regarded wastewater collection and treatment facilities, which include a treatment plant in Franklin and a maintenance facility in Laconia, are operated by NHDES employees on behalf of the communities benefiting from the facilities’ services. A total of nearly $70 million has been spent to construct these facilities and about $4.7 million is spent each year to operate and maintain them. Much has been accomplished by the WRBP over its years of operation.
