Rainwater harvesting provides an economical and simple solution to rainwater reuse for non-drinking water applications. Underground tanks provide simple water storage for rainwater after mechanical pre-tank filtration. Factory built management appliances are the heart of the rainwater harvesting architecture enabling simple installation and end user maintenance. The rainwater storage tanks have water drawn down via centrifugal pumps and pressurized water is distributed to the applications via the management appliance. Switch over to mains water backup is automatic when the rainwater tanks are empty until the next rainfall. Commercial users of rainwater harvesting can expect fast return on investment depending on roof area and water consumption. Residential rainwater harvesting systems can provide a source of water in the event of water usage restrictions. Ecozi provide German built technology from the largest rainwater harvesting market in Europe, benefiting from 18 years experience and best practice.
