Why does the City perform wastewater collection system smoke testing?

The wastewater collection system smoke testing process is used as a way to locate defective openings and inappropriate connections in the sewer system that allow rainwater runoff to enter, which decreases the system's capacity and ability to handle normal flows. By finding and repairing these defects, the city is able to defer expensive infrastructure needs and reduce the burden on utility customers.
