Abstract: A sealing cover assembly that provides a liquid-tight seal around the upper perimeter of an underground utility box includes an upper lid element, a lower lid element, and a resilient, elastomeric sealing element sandwiched in between. The sealing element includes a peripheral sealing lip that mates with a peripheral surface of the upper lid element, and a sealing flange that seats in a peripheral groove or slot in the lower lid element. The peripheral lip bears against an interior surface of the underground box to form a seal The underside of the lower lid element includes fastening elements for securing an accessory holder to the underside of the cover assembly. A central fastening assembly secures the upper and lower lid elements together with the sealing element captured therebetween.

Abstract: A catch basin assembly for draining water into an underground drainage conduit through a riser includes a housing having an open top and a bottom including an outlet section configured for connection to the riser. A debris trap is removably installed in the housing so as to capture and retain particulate debris from water flowing into the housing through the top thereof, the debris trap having an apertured portion that allows water to flow from the debris trap to the outlet section. The housing has a tapered configuration, whereby two or more housings, with the debris traps removed therefrom, can be stacked in a nesting relationship.

Abstract: A catch basin for draining water into an underground drainage conduit through a riser includes a receptacle having an open top and a base portion; an integral outflow conduit extending upwardly from an outlet opening in the base portion and having an inlet opening within the receptacle; and a trough in the receptacle that extends along a side of the base and below the level of the inlet opening to provide a trap for debris contained in water flowing into the receptacle. The receptacle tapers inwardly from top to bottom, so that a first receptacle can be nestably stacked in a second receptacle.
