CITY OF TONKAWA – PUBLIC NOTICE SEWER SYSTEM SMOKE TESTING – NOVEMBER 13, 2026 The City of Tonkawa would like to inform residents that contractors working with the City’s Public Works Department will be conducting smoke testing of the City’s sanitary sewer system today. What is Smoke Testing? Smoke testing is a common procedure used to identify potential problems within underground sewer lines. During this process, contractors introduce a non-toxic, artificial smoke into the sewer mains to help locate leaks, cracks, improper connections, and areas where groundwater or stormwater may be entering the sanitary sewer system. Residents may notice smoke coming from sewer vents, manholes, or the ground in areas where testing is underway. This is an expected part of the testing process and generally does not indicate a fire or emergency. Could Smoke Enter My Home? According to the contractor conducting the testing, smoke should not normally enter homes or businesses with properly functioning plumbing systems. However, smoke may enter a building if there are existing plumbing deficiencies, such as: * Dry or improperly functioning plumbing traps (P-traps or S-traps). * Deteriorated or improperly sealed wax rings beneath toilets. * Cracked, disconnected, or improperly installed plumbing pipes. * Other plumbing defects that allow sewer gases or smoke to enter the building. If smoke enters your home, it may indicate an existing plumbing issue that should be evaluated and corrected. Residents should avoid breathing concentrated smoke, ventilate the affected area, and notify the City’s Public Works Department. Why Is the City Conducting This Testing? This testing is part of the City of Tonkawa’s ongoing efforts to evaluate and improve our wastewater collection system. Identifying and repairing leaks and areas of unwanted water infiltration helps reduce unnecessary strain on our sewer infrastructure, improve system efficiency, and minimize the potential for future sewer-related problems. Important: If you observe smoke coming from a building and are unsure whether it is related to sewer testing or an actual fire, please contact 911. The City of Tonkawa appreciates the community’s patience and cooperation as we continue working to maintain and improve our public infrastructure. City of Tonkawa Public Works Department
