Smoke Testing & Sewer Survey
Bethlehem Village District Sewer System
Bethlehem Village District Sewer Department with the assistance of a Granite State Rural Water Association collection inspection crew will be conducting a survey of the Bethlehem sanitary sewer system. The survey will involve opening manholes in the streets and easements. A non-toxic smoke will be blown into the sewer mains to locate breaks and defects in the sewer system. The smoke that may be seen coming from vent stacks on buildings or holes in the ground is non-toxic, harmless, and creates no fire hazard. The smoke should NOT enter your home, unless the plumbing is defective or drain traps have dried up. If you have any seldom used drains, pour water into the drain to fill the trap.
If smoke should enter your home or building correction of defects on private property are the responsibility of the owner. A licensed plumber should be consulted to ensure the corrections are properly made. If smoke is observed you may contact a member of the survey crew working in your area. They will be pleased to assist you in identifying the source of the smoke.
Some sewer mains and manholes may cross property line easements or other rights of way. Whenever these lines require investigation, the crew will need access to the sewer mains and manholes. Clearing of some easements to facilitate access may be performed prior to the survey.
Video records or photographs are to be made of leaks that are found. The survey should begin on May 15, 2017 and require six-days for fieldwork (May 15-18, 24-25, 2017. If you have questions or observe smoke in your home, please call (603) 869-3440.
