For over 60 years, Superior Signal’s Superior Smoke testing technique has been used by municipalities in the U.S. and around the world. Hundreds of millions of feet of sanitary sewer mains have been effectively tested using Superior Smoke products, eliminating countless faults and the costly sanitary sewer overflows that would result. Smoke testing is the fastest and most cost-effective method to find all sources of surface inflow to sanitary sewers: anywhere that surface water can flow in, the smoke will come out. Finding problems quickly and cost-effectively is the key to reducing peak flows, stopping SSOs and saving money. Superior Classic Smoke Candles provide a highly visible smoke to find more faults at a longer distance. Superior Smoke Fluid Systems feature a stainless steel injector to maximize dry-smoke output, producing a higher-quality, liquid-based smoke. 800-945-8378; www.superiorsignal.com/II.
