Smoke testing is a technique used to identify illegal connections to sewer systems that worsen pollution and sewage overflows. The Water Pollution Control Unit has developed this innovative approach to tackle urban water pollution, especially during the winter season. By pumping smoke into sewer pipes, the surveillance team can locate improper connections or weaknesses in the infrastructure and notify owners for required repairs. This initiative has produced promising results, and the City plans to continue its efforts to protect the environment and water resources.
