Water collection options

[Lightspeed]

Suggestion: Mount 2 IBCs one on top of the other. The base one on SOLID engineering block foundation say 1ft above ground level.

If these were built against the house next to the main gutter down pipe they could be filled automatically with a simple water butt rainwater harvesting kit. Overflow water would be directed back to original drainage.

Building against the house allows for the IBCs to be braced to the wall to make them more stable.

Keeping everything above ground level will let you gravity feed your watering system, without the need for pumps.

This is not a pretty installation, so needs disguising. maybe building a wooden structure with a roof above them to look like a lean-to garden shed? This would also provide shade for the stored water, which is better storage condition.
