If desired, the Pump-Thru-Barrier™ could be trailer mounted to allow companies to pump out rainwater in more than one location. During normal rainstorms, the sump pump is activated and the rainwater is pumped into a series of dirt and oil sheen filters which prevent the Pump-ThruBarrier™ from clogging. These filters are easily removed and replaced in minutes. For colder climates, the Pump-Thru-Barriers™ can be outfitted with Customized Heating Blankets for the unit housing and the external water filter which cleans the water before it ever hits the unit itself. This unit is built in the US; it professional grade and one of the best Oil Water Seperators on the market today!
