Rain barrel setup
At the bare minimum, one barrel under one downspout. Add more if you find you use it.

A rain barrel under a downspout collects a surprising amount of water. A 1 cm rain on a small roof can fill it.
Use it for flushing toilets and washing straight away. Filter and treat it before drinking.
Drain it before the first hard freeze so it doesn't crack.
Steps
- Put a food-grade barrel on blocks under a downspout.
- Add a screen on top to keep out leaves and bugs.
- Fit a spigot and an overflow hose.
- Run it through a gravity filter and treat it before drinking.
