Claim:
A method of removing hydrocarbons from water entering a drain comprising the steps of: providing a filtration device comprising; a housing containing a filtration compartment and a treatment compartment, said filtration compartment containing at least one porous pipe having an upper closed end and a lower open end, and a filter floss around said at least one porous pipe, said treatment compartment is located below the filtration compartment and contains a hydrocarbon absorption media capable of absorbing hydrocarbons such that hydrocarbon contaminated water flowing from the filtration compartment into the treatment compartment is rendered substantially hydrocarbon-free; inserting a filtration device into a drain opening; securing said filtration device within said drain opening such that substantially all water entering said drain opening passes through said filtration device; placing a cover grate over said filtration device to prevent debris from entering said drain opening; and permitting water to flow into said drain opening, through said filtration device, and exit said filtration device substantially hydrocarbon-free.
