The Trans Tool SS-EVAP 50 Gallon Waste Water Evaporation System eliminates the need for a bulk wastewater hauler. The SS-EVAP can evaporate 50 gallons of wastewater in 12 hours, according to the company. The system leaves behind only contaminated sludge, which can be disposed of under local environmental laws. There is no hazardous waste leaving the shop, and no potential liability if there were a spill.
