Abstract: A molded, polyethylene wastewater chamber assemblage to be assembled and placed below ground level to receive, collect, and transfer wastewater to a treatment plant. The chamber has pipe spigots extending horizontally from its opposing bottom ends that receive input or output pipes of commercially available pipe design, and a riser base on top of the chamber with riser spigot attached thereto that receives a riser of conventional design, and a molded polyethylene lid to seal the riser to be watertight. Two chamber spigot extensions for attachment to the chamber extend the capability of the chamber to accept input and output pipes of various outside diameter.

Abstract: An Aqua-Blok that fits into a frame or cone of a manhole directly beneath the cover, in the frame below the cover or within the cone to catch water that seeps into the manhole. Aqua-Blok is a polyurea, flexible bowl that rests on the frame directly under the cover or is mounted in frame or the cone. When used in the lower frame, it has a closed cell gasket on its outer top side, and an adjustable stainless steel ring on its inner circumference to press it against the frame. When Aqua-Blok is placed in the cone, it uses a rubber mount placed within the cone to mount Aqua-Blok. The rubber mount has a core with concentric rubber rings on its outer periphery that match the sloped sides of the cone. It has a circular cavity in its inner circumference to receive the pressure ring. The pressure ring forces the core and the concentric rings against the wall of the cone in a watertight fit. The bowl is seated on the mount where it catches any water that flows into the manhole from above it.

Abstract: A watertight waste water access fitting that is placed below ground level to mate with a pipe from a waste water source and a pipe from a sewer system and with access to its inside from ground level. The fitting is a preformed, polyethylene, one piece hollow body with three formed extensions from the body. Two of the extensions are formed at the bottom sides of the fitting, and one is formed at the top. The bottom side extensions mate with water pipes, and the top extension can be opened to expose the inside of the fitting for maintenance. The bottom extensions are formed of connected segments of decreasing outer diameter with a cutting guide on each segment. The segments can be cut to mate with various diameters of pipe. The top segment has a cap and cutting guide where the cap can be removed by cutting the segment at the cutting guide.
