Smoke Testing of the Sewer Lines

For our Marco Shores customers only, the City of Marco Island will be testing the integrity of the sewer collection system, utilizing smoke to find and repair leaks. This  test, which involves forcing smoke into the sanitary sewer lines, will check for leaks, breaks and defects in the system. The smoke is odorless, creates no fire hazard, and  should not enter homes or businesses unless you have defective plumbing in need of repair

Smoke testing will take approximately one day to complete and will take place on Friday, 12/4/20 between 8:30 a.m. and 4:00 p.m. This test is part of our continuing effort to provide a safe, economical, efficient and environmentally sound  wastewater system throughout Marco Shores/Hammock Bay area. The smoke testing  

procedure has been recommended by the United States Environmental Protection  Agency as an effective means of identifying problem areas in the sewer system.  Eliminating system defects and illegal connections will help the City remain in  compliance with federal legislation regarding sewer systems maintenance and sanitary sewer overflows. 

A map of the area that will be tested is on the City website and is attached. 

How the Test Works 

The test consists of forcing safe, vegetable-oil-derived smoke into the sewer lines and observing where it escapes in order to determine the location of leaks and defects. Odorless and safe, the smoke leaves no residuals or stains and has no adverse effect on people, plants, oranimals. 

What to Expect 

While smoke can be expected to billow from manhole covers and vent stacks in roofs, it should not enter homes. To reduce the likelihood of smoke entering a building, the City recommends that you pour at least 2 gallons of water into seldom-used sinks and floor drains, where the smoke could arise due to lack of water pressure. This may be done at any time prior to the test. If smoke does enter the

home during testing, immediately leave the building, notify the crews that are  conducting the test or call the City at 239-825-9001. It is the homeowner’s responsibility to notify a plumber and to remedy the plumbing defect. 

If Problems areFound 

Smoke coming from the vent stacks on houses is normal. However, smoke coming from holes in the ground is not normal and is considered a defect. All such defects will be photographed and logged. The City will contact property owners if a defect is located on private property. Property owners do not have to be home during the smoke testing. 

Special Requests 

While smoke testing is safe, residents who have special needs or previously received medical treatment for a heart, lung, or respiratory issues may contact the City of Marco Island at 239-825-9001 to coordinate testing times and devise  alternative testing procedures if necessary
