Systems and methods for managing waste (including liquid, solid, and mixed waste) without using a sink, worktop, or countertop disposal feature. Specific examples provide particular use in connection with an aircraft or other vehicle galley, lavatory, or any other location in which waste that requires disposal is generated. The disclosed embodiments may be installed in an initial galley or lavatory, or they may be used to retrofit an existing environment, such that an entire new disposal system or new sink footprint is not required.

A overflow chamber that can discharge rainwater and soil according to the present disclosure includes: a receiving unit having a receiving space; an interceptor port formed at a side of the receiving unit and selectively opening/closing in accordance with the amount of received object received in the receiving unit; a discharge port formed at another side of the receiving unit; and a first discharge pipe communicating with the discharge port and convexly bending upward at least one time.

A stormwater collection, treatment, and aquifer replenishment installation includes a stormwater drain for receiving surface stormwater, a dry well downwardly extending underground to an outlet proximate to a water table over an aquifer, a tank structure at least partially disposed underground and coupled with the stormwater drain and the dry well in stormwater communication, a stormwater treatment system enclosed within the tank structure between the stormwater drain and the dry well for converting surface stormwater into treated stormwater, the tank structure for conducting surface stormwater to the stormwater treatment system between the stormwater drain and the dry well, and the dry well for receiving and gravity feeding treated stormwater from stormwater treatment system to the outlet.

An automatic sewage regulation system and a regulating method are provided. The automatic sewage regulation system includes buffer tanks, an equalization tank, a sewage treatment apparatus and an automatic sewage regulating device. The automatic sewage regulating device includes sensing modules for sensing and transmitting water quality sensing values of sewage in the buffer tanks to a control module which outputs regulating signals to water flow regulators, so that the water flow regulators can regulate flowing volumes of the sewage of the buffer tanks according to the regulating signal, to keep a water quality sensing value of the sewage in the equalization tank within a preset range, thereby preventing the equalization tank from converging sewage having excessively-high or excessively-low water quality sensing value. As a result, burden of the sewage treatment apparatus can be reduced, and the lifetime of the sewage treatment apparatus can be extended.
