Water butts work by collecting rainwater from your roof and storing it for later use. Here's a breakdown:
- Rainwater Collection: Rainwater falls on your roof and flows into the gutters.
- Diversion: Instead of going down the drainpipe, a diverter is installed. This diverter redirects the rainwater into the water butt. According to our reference, "with a water butt, the rainwater falls from the roof into the guttering in the same way, but rather than flowing through the downpipes and down the drain, a diverter is inserted to collect it all in the butt."
- Storage: The water butt holds the collected rainwater.
- Overflow: When the butt is full, excess water is diverted back to the drain. The reference notes, "Once it has reached maximum capacity, the rest of the water will simply divert to the drain."
