RAINFALL COLLECTION SYSTEM

摘要

A rainfall collection system extending over a wide area funnels collected rainwater into a central storage tube. A platform consisting of a plurality of water-impermeable membrane panels laid over a graded bed overlays a flexible watertight collection tube disposed within a swale running along the apex of the bed beneath the membrane panels. Rainwater is automatically pumped into the collection tube as it accumulates on the membrane panels, preventing losses due to evaporation and percolation into the ground. The collected rainwater is stored in the storage tube and transported by an aqueduct system or tank trucks. The membrane panels may be transparent or translucent, allowing maintenance personnel to detect leaks in the panels by darkened areas of the ground visible via aerial inspection, and may be marked with coordinate identifiers allowing maintenance personnel to readily locate damaged areas from the ground. A grid of maintenance corridors interspersed throughout the collection platform allows access to the membrane panels for maintenance and repair. Sediment catchment pits may be located near each end of the tube to collect sediment.
