Another important function of the inlet is the conveyance, and storage of rainwater. Systems can be asintroduction of oxygen into the lower layers of the tank simple as a rain barrel for garden irrigation at the end of awhich maintains a fresh supply of water while preventing downspout, or as complex as a domestic potable system anaerobic conditions from forming.or a multiple end-use system at a large corporate campus.SYSTEM COMPONENTSOnce a maximum level is reached in the tank, theRegardless of the complexity of the system, the rainwater innovative overflow siphon (RTX-OVRFLW), with its skimmerharvesting system comprises the following basic effect, removes particles lighter than water (e.g. flowercomponents:pollen, oils, etc.) that float slowly to the water surface.
