Rainwater Collection Systems include any vessel, tank or other basin that is designed to collect and store excess rainwater. Examples of these are barrels, concrete storage tanks, arched chambers, detention basins and plastic modular systems – such as Rainstore3. Reasons to collect excess stormwater vary from flood prevention to harvesting for the purpose of reuse. The efficacy of these systems differ based on size and design.
Rain barrels and concrete storage tanks are limited in their capacity because of their impervious walls, whereas arched chambers, detention basins, and plastic modular systems have unlimited capacity. Arched chambers and plastic modular systems have the advantage of storing water underground, allowing for usable space such as parking lots or green spaces on top.
Only Rainstore3 is strong enough to support the weight of structures such as a parking garage or small building.
