ABSTRACT:
The containment system provides a simple but automatic closure device that requires minimum and low cost maintenance. Storm water can pass through the drains and does not require manual pumping like the prior art systems. Small mounts of contaminants will be absorbed as the water passes through the drain ensuring the storm water leaving the containment area is free of contaminants. Hydrophobic swellable polymer particles are located in the drain to seal the drain in the event that organic liquids such as oil, gasoline, etc. flow into the drain.
