Abstract (en)
[origin: WO2017142878A1] A plastic article useful as a riser assembly (18) for a septic tank or as part of another structure is comprised of a multiplicity of identical shape conical wall plastic risers (20). The risers are attached to each other at joints (42, 142) by respective tabs (26, 36) which engage respective rim segments (22, 38). Each end of the riser has alternating tabs and rim segments. A riser assembly wall 30 undulates in the lengthwise direction. The risers nest within each other for shipment or storage. A safety grating (60) having hinged arms (62) sets within the interior of a riser (20). An adapter (70) enables attachment of a riser (20) to a tank (75).
