VALDOSTA, Ga. (WTXL)--City workers in Valdosta are looking for any defects in underground pipes. They'll spend the next 18-20 weeks smoke testing 120 miles of underground sewer lines. This will help them find areas in need of repair. 

The sewer system is made up of more than 300 miles of sewer lines. One hundred eighty have been inspected since January 2014. 

Here's more information from the City of Valdosta: 

As part of the Smoke Testing Program, the city sewer system was divided into five zones. As of July 2016, zones 1, 4 and 5 have been smoke tested. Smoke testing in zones 2 and 3 will be completed during Phase Four.

 Informational door hangers will be distributed before the work begins in each Phase Four area to notify residents and businesses in the area about what to expect (view the door hanger, smoke testing photos and Frequently Asked Questions fliers). The white or gray-colored smoke used during this test is non-toxic, non-staining, odorless, and creates no fire hazard or any harm to the environment.

During the testing, it is normal to see smoke exiting sewer manholes, as well as plumbing vents on the top of buildings. While it is very unlikely for smoke to enter a building, it is recommended that residents and businesses in the test area pour at least 16 ounces of water down all drains to ensure that plumbing drain traps are holding water. The water in drain traps will prevent the smoke from entering the inside of homes and businesses.

 Smoke that does enter a home or business during the test indicates that there may be faulty or defective internal plumbing, which should be repaired as soon as possible. It is very important for property owners to make these repairs, since smoke entering any structure during the smoke test is also an indication that sewer gases are likely entering as well from that same location. If smoke does enter any building during the test, citizens are advised to open windows and doors to allow the smoke to clear for approximately 15 minutes.

The city's contractor is communicating specific testing locations with the Valdosta Fire Department, in the event that calls are received on account of the smoke. Also, special arrangements will be made for persons with respiratory or other serious medical conditions.

The contractors performing this work will be wearing identification tags that will be clearly visible to others. Inclement weather could postpone the testing, as smoke testing cannot be accomplished during or immediately after heavy rain. In that case, businesses and residents should expect the process to take a few days longer.
