Smoke testing of Trenton's sanitary sewer system resumes today. It's an effort to determine storm water inflow and infiltration into the system.
Trenton Municipal says smoke that may be seen coming from vent stacks on houses, or holes in the ground, is non-toxic, harmless, has no odor, and creates no fire hazard.
TMU says smoke will not enter homes if the plumbing is installed properly and drain pipes are not dry. If smoke enters a residence or business, it's recommended a plumber be consulted. A member of the smoke testing crew working in the neighborhood also can be consulted. TMU notes, if smoke can enter through the plumbing, there's also a potential for dangerous sewer gases to enter the structure more frequently.
Persons with seldom used drains, such as floor drains in basements, are encouraged to pour water in the trap, to prevent smoke from entering there.
TMU says drain traps always should be filled with water to prevent sewer gases, or odors, from entering the building. To help prevent smoke from entering around the
washing machine drain pipe, tie a damp rag around the opening.
About 48 hours before smoke testing, printed door notifications are to be distributed to each residence in the area being tested. The door hangers will provide information regarding the procedure, plus contacts for more information.
The Trenton Board of Public Works last year approved Trekk Design Group to assist in the analysis of Trenton's sanitary sewer system.
