b'How it WorksThe RainBasin system consists of a series of interconnected vaults. Stormwater runoff can enter the system through multiple options such as inlets, outlet openings, curbs, grates and downspouts. The accumulated stormwater will be stored within the system with a residence time varying with application and volume.System Benets Onsite stormwater management Stormwater runoff emulates natural conditions Mitigation of downstream ooding Modular structure for designconsiderations Rainwater harvesting optionMaintenanceThe RainBasin system is designed Sizing and Design Considerations for easy maintenance and longevity.
