In an effort to improve the quality of our wastewater collection system, the city has contracted with Burgess & Niple to perform smoke testing in various locations to detect breaks and defects in the sanitary sewer system. Over the next few days, you may see smoke coming from vent stacks on houses or holes in the ground. The smoke is harmless, has little odor, and creates no fire hazard. Crews may need to access sewer manholes in utility easements. Burgess & Niple personnel are uniformed and carry identification badges. You do not need to be home and at no time will field crews have to enter your home or business. Please see the map and flyers below for additional information on the smoke testing. Should you have any questions regarding this testing, please contact the City Service Center at (972) 780-4900 or Gerald Boman of Burgess & Niple at (512) 626-9485.
