As Trecan is a supplier of both portable and stationary types of snowmelters, we are not usually involved in acquiring any type of operating permits for the customers. A snowmelter basically speeds up the natural process of melting snow. If, for example, a shopping mall parking lot contains contaminated snow, which is left to melt naturally, the melt water will most likely run into a storm water catch basin. The liquid type contaminants will enter the catch basin while the solid debris will lie all over the ground – or blow all over the place, as plastic bags seem to do.
