Rainwater collecting barrel without connection to a gutter.

Watch the 1-minute pitch video

Long description

Add a mechanism with a retractable or tightened collar to the water barrels. This will increase the rainfall surface and the barrel will fill itself without the need to attach it to the gutter.

Increasing the radius of the barrel to 100 cm (flange/collar approx. 75-80 cm) increases the received water more than 11 times.
