Abstract

An underdrain apparatus includes one or more underdrain blocks and an anchor assembly that includes one or more support members. Each of the underdrain blocks includes a top wall, a bottom wall, a pair of opposing side walls, a pair of opposing end walls, and a center separation wall that extends between the pair of opposing end walls. The center separation wall of at least one of the underdrain blocks may have one or more apertures formed therein, the apertures configured to receive at least one of the support members. One or more of the side walls of the pair of opposing side walls of the underdrain blocks may have one or more side clips. At least one of the side clips defines an aperture for receiving a support member.
