A plastic article useful as a riser for a septic tank or as a water tank article is comprised of a multiplicity of plastic rings which are attached vertically to each other at joints. Ring pairs which alternately have inward and outward sloping conical walls nest within each other for shipment or storage. A lid is shaped for use with the topmost ring to cover the opening irrespective of which conical shape the ring has.
