The invention relates to an integrated belowground vault with filter catch
basin, that allows the runoff water to enter into a belowground two-part
vault passing through a commercially available replaceable filter before
being transferred out to the sewer, flood control system or out through a
French drain consisting of a cavity below the device that is filled with
drain gravel. A layer of filter cloth can optionally be placed over the
drain gravel. This device will be manufactured in variety of sizes and
shapes and made from several different materials. The device has the
unique ability of being capable of filtering low flow water runoff while
allowing high volume to pass through with the added benefit of not
retaining water that can become a mosquito breeding ground.
