Rain barrels function by collecting rainwater, thereby reducing stormwater runoff. They achieve this by being placed directly underneath a shortened downspout. This configuration allows the downspout to divert roof runoff directly into the rain barrel.
Here's a breakdown of how this process works:
- Rain Collection: When it rains, water flows off the roof and into the gutters.
- Downspout Diversion: Instead of flowing directly into the ground or storm drain, the downspout is shortened, and a rain barrel is placed underneath.
- Water Storage: The rainwater is then channeled from the downspout into the rain barrel where it is stored for later use.
This process allows homeowners to collect and reuse rainwater for purposes like watering gardens or lawns, and thus reducing the overall stormwater runoff and its environmental impact. The use of rain barrels is an easy and effective method of rainwater harvesting.
