Patent number: 11585079Abstract: A method to enhance the ability of a stormwater containment volume to flow and flush solids and liquids. Implemented by depositing rock into shaped piles formed at the rock's angle of repose, the resultant inclined surfaces are covered with suitable waterproof material and covered with more rock up to the top surface. Stormwater flushes solids deposited on the surface downward into the volume where they contact the inclined surfaces. Water and solids flow down the inclined surfaces at increased velocity toward collection drainpipes at their base. Because sediment flows into drainpipes, it does not flow to the bottom of the volume or become stagnant or reduce the volume's capacity. This creates a low-cost stormwater containment system that can support vehicle travel on its surface, requires no concrete or sewers, is self-cleaning, accessible for cleaning, or both, and does not require human access to the bottom surface for maintenance.Type: GrantFiled: June 9, 2021Date of Patent: February 21, 2023Inventor: Daniel George Cencer
