ABSTRACT:
A water filtration system is disclosed for removing solid particulates from water, and in particular from storm water collection basins prior to passage into a storm water sewer system, comprising an ingress conduit to bring water into the system, a primary filter, a secondary filter of granular material, a primary filter carrier receptacle containing the primary filter which allows water to pass through but not the granules of the secondary filter, a collection conduit to remove the filtered water, and an access port connecting to the carrier receptacle which allows the primary filter to be removed from and returned to the carrier receptacle without disturbing the secondary filter. Preferably the system also comprises a rigid, water impermeable, closed housing. Alternatively, the housing may be constructed of a number of modular units joined together.
