Rain barrel - $60 (San Luis Obispo)

Collect rainwater to use for watering the garden.
We also pour in water that we collect in the shower while waiting for it to heat up.
Helps with the water bill, but we are moving and don’t need it anymore.
Only issue is the spigot is clogged so to get water, we just open the lid and draw directly from inside the barrel.
Also do not know where the hose for runoff is but we never had to use it.
