A complete storm water management system and process which performs both drainage and treatment tasks and incorporates a wetlands water treatment system. This system creates an infrastructure, flow control which is multi-level and multi-stage. This system incorporates a self-contained wetlands treatment system. This is a modular system which includes three or more linear chambers through which the storm water or other influent passes and is cleaned. The influent which flows into a storm drain, curb inlet, or inflow pipe into the system is directed first into a screening type catch basin inset filter within the first chamber of the system. The wetlands chamber is composed of one or more modular segments which may be made in various depths, lengths and widths. The influent is treated within the first chamber before it passes out of this chamber into the incorporated wetlands system. The water flows through the wetlands chamber where it is further filtered and decontaminated through both an aerobic and anaerobic process. In situations of high runoff there is a bypass component which runs directly from the first chamber and bypasses the wetlands chamber dumping the pretreated water into the discharge final chamber. This system is fitted with a variable level treatment component designed in such a way to offer variable discharge rates and thus vary the level of treatments over a wide range of flow rates. The system can be placed underground, and below concrete, such as in parking lots or park areas.

Along with sewage collection in the well, the sump well drains automatically and intermittently to the vacuum drainage system, has a simple structure, and does not require a lift pump, so that the problems of being low in safety, easy in blockage, difficult in cleaning, high in power consumption and the like caused by assembling the lift pumps on multiple points can be avoided, and sewage collected by gravity flow can be lifted to the vacuum drainage system without extra additional power,and the sump well is convenient to check and maintain.

A riser system for use at the access opening of a wastewater treatment tank includes an adaptor ring affixed to the top of the tank, and a mating riser. The adaptor ring and riser have ends with mating circumferential L-shape sections. There are horizontally projecting tabs spaced apart around the upper end of the adaptor. The tabs engage a corresponding number of L-shape slots which are spaced apart around the circumference of the bottom end of the riser. When ring and riser are mated, rotation of the riser relative to the adaptor causes each tab to move circumferentially to a recess in the slot, which locks the tab in position. Micro-ridges on horizontal mating surfaces of the L-shape sections help form a seal between the two parts.
