Smoke Testing of Sanitary Sewer

The City of Sanford Engineering Division has contracted with W.K. Dickson and Compliance EnviroSystems, LLC to conduct a physical survey of a portion of the sanitary sewer system. Over the next few days field crews, will be out conducting this work. View a map of affected areas.

The survey will involve opening and entering manholes in the streets and easements. An important task of the survey will be SMOKE TESTING of the sewer lines to locate breaks and defects in the sewer system. 

What to expect: Residents may see smoke coming from the vent stacks on houses or holes in the ground, This smoke is NON-TOXIC, HARMLESS, HAS NO ODOR, AND CREATES NO FIRE HAZARD.

How to prepare: If you have any seldom used drains, please pour water in the drain to fill the trap, which will prevent smoke from entering. Drain traps should always be filled with water to prevent sewer gases or odors from entering the building. The smoke should not enter your home unless you have defective plumbing or dried up drain traps. If this occurs, please call the City of Sanford at the numbers posted below.

Some sewer lines and manholes may be located on the backyard easement property line. Whenever these lines require investigation, members of the inspection crews will need access to the easements for the sewer lines and manholes. 

Important: Compliance EnviroSystems, LLC personnel are uniformed and carry identification. Homeowners do not need to be home and AT NO TIME WILL FIELD CREWS HAVE TO ENTER YOUR BUSINESS OR RESIDENCE. A City of Sanford construction inspector will accompany Compliance EnviroSystems, LLC should you have any questions or concerns.

We anticipate the smoke testing will require a few hours in the affected areas (see map). The information gained from this study will help the City identify areas of improvement in our sewer collection system.
