ABSTRACT:
In order to prevent hazardous substances--oils, fuels, deicing liquids--spilled onto the ground or pavement, e.g. at an airport, to enter storm sewer system with subsequent contamination of the environment, a catchbasin structure is provided comprising a receptacle with an opening closable with a valve in a manner to seal off the entry of the liquid into the storm sewer system. Instead, the liquid can be kept in the receptacle and on the ground in the area adjacent to the catchbasin, or selectively directed to a storage tank system for treatment or recovery.
