Abstract: A filter for a storm water inlet having a surface opening for receiving storm water runoff comprising liquids and solids and discharging said runoff into an interior compartment below having a substantially vertical interior wall or walls defining a cross-sectional area. The filter comprises one or more precast pervious concrete filter elements, the element or elements being formed such that the filter substantially fills the entire cross-sectional area of the interior compartment. Also, a storm water inlet including such a filter, and a method of adding such a filter to a storm water inlet.

Abstract: Fiber-reinforced compositions for forming concrete are disclosed. A fiber-reinforced dry-cast cementitious composition includes a cementitious component, aggregate, and at least one reinforcing component selected from the group consisting of metal fibers, synthetic fibers, and rubber pieces. A fiber-reinforced non-cementitious composition includes a pozzolanic component, aggregate, and at least one reinforcing component selected from the group consisting of metal fibers, synthetic fibers, and rubber pieces. The composition excludes any cementitious component. Fiber-reinforced concrete structures obtained by hardening the above-described compositions are also disclosed.
