Abstract: In certain embodiments, a system filter has a hollow, perforated, inner structure inside a hollow, perforated, outer structure that define an annular gap that receives granular filtering media retained by an (optional) media liner. An outer filter surrounds the outer structure. An (electric) pump may be located within the inner cavity of the inner structure or external to the system filter. When deployed in an underground vault, vault water flows through the outer filter, the outer structure, the outer portion of the media liner (if present), the filtering media, the inner portion of the media liner (if present), and the inner structure into the inner cavity from where the pump moves the filtered water out of the vault. The outer filter and/or the media liner may have a lipophobic, hydrophilic material that allows water to pass while blocking lipids without having the lipids adhere to the material.
