Smoke testing of sewer to begin in Lockridge

Oct 11, 2016

LOCKRIDGE – Sanitary sewer investigations are being conducted today in Lockridge.

The investigations are a joint venture between the city, French-Reneker-Associates Inc., and Engineers & Surveyors. The investigations will involve blowing a nontoxic white smoke into the sanitary sewers and recording where it leaks out.

The purpose of the work is to locate areas where surface and ground water can enter the sanitary sewer system and contribute to its periodic overloading. These areas typically consist of leaks in the sanitary sewer system, area drains and cleanouts and downspouts connected to the sanitary sewer system.

All of the sanitary sewers in Lockridge will be tested. During the investigations, residents may notice some of the following:

• Smoke emitting from the sewer vent pipe on the roof. This indicates that the vent pipe is functioning normally. One of its functions is to provide an outlet for gases of any kind that might build up in the sewer.

• Smoke in the basement. If this occurs, residents may have a faulty trap in their plumbing. Sewer gas could also enter the house through this faulty trap. Some sewer gases are poisonous and explosive.  Residents should notify their plumber and have him carefully inspect the installation and correct the potential problem. These traps must be full of water at all times to keep gases out of the house. In many cases, the addition of water is all that is necessary to correct the situation.

• Smoke emitting from the eaves.  If this occurs, the downspouts are connected directly to the sanitary sewer. The hookup should be disconnected as it contributes to overloading of the sanitary sewer system.

• Smoke rising from the ground. This indicates faulty pipe joints or broken sewer pipes and the smoke is escaping from the sewer through cracks in the ground.

• Smoke emitting from storm water drains. This indicates that the storm water drain is connected in some fashion to the sanitary sewer system.

If smoke is noticed in these or other locations, residents are asked to notify the testing crew.
