How Rainwater Harvesting is done
Rainwater is channelled into roof drainage points where it is collected in a rainwater harvesting storage tank. Prior to entering the storage tank, reclaimed rainwater is processed through a mesh filter which removes larger debris like leaves and avion-related items.
Rainwater enters the main storage tank via an inlet calmer preventing find sediment on the base of the storage tank from being disturbed. In the event of the storage tank becoming full, an automatic overflow ensures excess rainwater is channelled into the drainage system. The overflow is complete with a none-return valve arrangement to ensure no objects can enter the rainwater harvesting storage tank.
The rainwater harvesting storage tank contains level sensors and submersible pumps which, when a demand for water is detected by the control panel, will take water from the cleanest part of the tank via a floating suction filter.
Rainwater Harvesting storage tanks are sized based on local weather data, occupancy, and roof space. Tanks can be located underground or below ground.
