I developed the Aquatrap disc in 1997 -A sidewall from a motor car tyres and the centre filled with rubber from a tube-or any rubber pieces patched together to fill the centre hole. Rubber is a great insulator and I discovered I n food gardens in Cape Town that the soil was kept warm apart from the Aquatrap saving water-this massively improves growth rates in veggies.

Bergvliet High School did research and entered the Youth Water Competetion and won.

Numerous other products have evolved- Planters, Worm Bins and Collars

School /Community food gardens

How will you scale your idea? Please describe in detail your plan to scale your concept.

How is your idea innovative?

What inspired this idea?

In Cape Town at the time there was a water issue(1997) similar today- so any idea to save water was good.
