Rain catchers, also known as rainwater harvesting systems, work by collecting and storing rainwater for later use. The process is simple and involves a few key components to efficiently gather and preserve this valuable resource.
The Basic Process
The system relies on gravity and a collection surface (typically a roof) to gather rainwater. Here's a step-by-step breakdown of how it works:
-
Rainwater Collection: When it rains, water falls onto your roof.
-
Gutter System:
- Water flows down your roof and into a gutter system. This gutter system is strategically placed to capture as much runoff as possible.
- Gutters channel the water towards a downspout.
-
Downspout and Diversion:
- The downspout directs the water downwards, towards a storage container.
- A rain diverter, manually installed on the downspout gutter, can be used to connect a hose directly to the barrel.
-
Storage: The water is then channeled into a storage container, such as a rain barrel or a larger tank, and stored until needed.
Components of a Rainwater Harvesting System
Component | Function |
---|---|
Roof | Serves as the primary collection surface. |
Gutters | Channels water from the roof to the downspout. |
Downspout | Directs water from the gutters to the storage container. |
Rain Diverter | Optional device to connect a hose directly to the barrel. |
Storage Tank | Holds the collected rainwater. |
Filter | Removes debris and contaminants from the water (optional but recommended). |
