City of Laconia Public Works Department

Sanitary Sewer

The City of Laconia is a member of the Winnipesaukee River Basin Program (WRBP) - a state owned and operated regional wastewater system serving 10 communities in the Lakes Region. The treatment facility is located in Franklin, NH. Funding for the WRBP is provided through the sewer rates assessed by the member communities. For more information on the Winnipesaukee River Basin Program please see the WRBP Website.

Feeding into the WRBP infrastructure, Laconia manages 18 sewer pump stations and approximately 91 miles of gravity main and 13 miles of force main. Connection to the sanitary sewer system is required when an improved property is within 250' to the public sewer system. The point of measurement is from the closest part of any structure which contains plumbing to the sewer system. If easements are necessary, the distance would be measured along or across the shortest available easement.

  • For residential facilities, apartments and other similar use, each single family living area is one unit (a duplex would be two units, etc.).
  • For hotels, motels, convalescent homes, hospitals, jails and other similar uses, each room is considered one-half unit.
