Abstract
A catch basin cover and lid takes the form of a reinforced concrete slab-like body of a desirable shape and provided with a central opening and a lid and replaces the cast iron catch basin covers heretofore generally employed. The reinforcing members are shaped to support the peripheral edges of the concrete slab and are positioned transversely therein so as to engage and support a reinforcing ring defining the access opening in the cover, the reinforced concrete catch basin cover and lid are uniformally sized by formation of the same in an appropriately shaped outline mold uniformly spaced with respect to the reinforcing members of the catch basin cover.
