Multiple US Cities Conduct Smoke Testing on Sewer Systems

Several U.S. cities are conducting smoke testing of their sanitary sewer systems to detect cracks, leaks, and improper connections using a harmless, odorless, and non-toxic smoke. In Joplin, Missouri, testing will occur in the College Skyline area starting August 4 for about four days, with smoke expected to be seen from roof vents, utility holes, or ground cracks; residents are advised to keep water in their drain traps and to consult a plumber if smoke enters their homes. Similarly, Shallotte, North Carolina, plans smoke testing in the Owendon and Village Point Estates areas on August 5 and 6, assuring that the smoke is safe for people, pets, and property. Stratford, Connecticut, will perform smoke testing on August 1 on Devon Street, alerting local fire services to prevent confusion during the process. Residents in all locations are informed via door hangers or social media and are reassured about the safety of the smoke, which poses no health risks. Local authorities encourage residents to prepare by running water in drains and to report any plumbing issues indicated by smoke intrusion indoors.
