Abstract: An immproved lid assembly for roll-off sludge containers is provided wher the lid assembly is supported by oppositely disposed lip portions which extend longitudinally along each side of an opening formed in an upper side of the sludge container. The lid assembly comprises a plurality of lid members and a roller assembly connected to each of the lid members so that the lid members can be selectively moved between a first position and a second position relative to the opening of the sludge container. In the first position the lid members are telescopically disposed in adjacent lid members, thus providing access to selected portions of the opening in the sludge container. In the second position, the lid members are extended and close off the opening in the sludge container.
