7 Different Types Of Rainwater Harvesting Systems
- Water Butt. One of the most basic types of rainwater harvesting systems; water Butt collects rainwater in a container from natural rainfall and/or drain pipes.
- Direct-Pumped.
- Indirect Pumped.
- Indirect Gravity.
- Gravity Only.
- Retention Ponds.
- In-Ground Storage.
How does water harvesting work?
Rainwater harvesting systems capture rainwater by directing it from large surfaces (e.g. roofs) to an underground or over-ground holding tank. The harvested rainwater is filtered and then pumped directly to the appliances or to a header tank. Domestic or commercial applications include: Flushing toilets.
