Abstract: A drain cover assembly that retains mesh on its upper surface via a channel-fastening system that is integrated into the drain cover's perimeter zone. The mesh is retained on the upper surface of the drain cover in a robust and permanent fashion. The drain cover can be configured to provide structural rigidity for supporting a load applied to its upper surface. The drain cover can be adapted to allow for its use in existing or newly constructed drainage system installations. The meshed upper surface of the drain cover can be configured to be flat or raised in profile. The meshed upper surface of the drain cover prevents mosquito habitation and breeding within the associated drainage system and prevents fine debris particles from clogging the drainage system's flow conduit.
