Smoke generators from Superior Signal can help find the sources of surface inflow that are causing wet-weather sanitary sewer overflows. They provide a fast, easy, and inexpensive way to find leaks and faults in collections systems and laterals, as well as building plumbing, drains, and vents. Classic Smoke Candles provide visible smoke to detect more faults at a longer distance. Smoke generators are available in sizes to meet any need, from 30 to 500,000 cubic feet. Smoke Fluid Systems use an insulated heating chamber with a stainless steel injector to maximize dry smoke output and produce quality liquid-based smoke. They meet NASSCO, Water Environment Federation, and Environmental Protection Agency standards. 800-945-8378; www.superiorsignal.com.
