When water is scarce and every drop of water is precious, the only practical option for fighting a fire is CAFS. According to the U.S. Fire Administration, it can take 15 gallons of water to match the effectiveness of a single gallon of ONE STEP CAFSystem foam from Waterous. This saves water without sacrificing results. When fighting a fire, everything counts – even water consumption – and only ONE STEP CAFSystem accounts for it all.
