摘要： 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.

摘要： The invention relates to a method for determining a Pump Station Capacity Measure (PSCM) in relation to a theoretical or actual Precipitation Event in the area of the pump station (1), wherein the pump station (1) comprises a tank (6) for temporary storage of a liquid, an inlet (7) for influent liquid, an outlet (8), and at least one pump (2) configured for transporting the liquid away from the tank (6) via said outlet (8). The method is characterized by the steps of: determining a Precipitation Inflow character (IN-RAIN) of the pump station (1) that is representative for the inflow of liquid to the pump station (1) originating from theoretical or actual Precipitation Events in the area of the pump station (1), determining a Dry Inflow character (IN-DRY) of the pump station (1) that is representative for the inflow of liquid to the pump station (1) not originating from Precipitation Events, determining a Pump Station Max Capacity (PSMC) that is representative for the maximum output capacity of the pump station (1), and determining the Pump Station Capacity Measure (PSCM) based on: a maximum value of said Precipitation Inflow character MAX(IN-RAIN), a maximum value of the Dry Inflow character MAX(IN-DRY), and said Pump Station Max Capacity (PSMC).
