Public Works smoke testing begins in some neighborhoods

Post Date:04/21/2017 7:57 a.m.

In the following weeks the City of Pearland Public Works Department will be smoke testing sanitary sewer lines in some neighborhoods in the City of Pearland.  This type of testing is done to evaluate the performance of the sanitary sewer collection system and to identify areas in need of improvement.     

In the affected neighborhoods, residents may notice smoke coming from sewer vents, gutters, downspouts or from the ground along sewer lines.  The purpose of smoke testing is to identify Inflow and Infiltration (I&I) of rain water or groundwater into the sanitary sewer system.  I&I causes the sanitary sewer collection system to carry storm water to the sanitary sewer treatment facility.  The sanitary sewer collection system is designed as a sealed system and does not perform optimally when storm water enters the system.

City employees will be evaluating the collection system as the test is performed. If there is an area of concern requiring repair, you may receive a Notice of Noncompliance. City staff will identify the issue and ask you to remedy the situation.  The City will follow up with you soon thereafter. Failure to address the issue is a violation of City code which could be result in a fine, so compliance is important.       

Smoke testing occurs between the hours of 8 a.m. and 5 p.m. If you have smoke or odor inside your house, this may come from plumbing or fixtures connected to the sanitary sewer system. This type of testing smoke is harmless to plants and animals, white to yellowish-white in color, and may have a slight odor.  If the smoke enters your residence please ventilate your home.
