Montana Wildlife Gardener: Repurposed kitchen sink! I love this idea. Even better if there was an actual water supply. I would omit the bucket and run a drain pipe straight down or towards the back. Dig a shallow hole directly under the pipe and filled with pebbles, rocks or even pieces of broken terracotta pots. To take the water away dig a shallow trench which would branch out into the garden areas. No lugging buckets of water away and the garden is watered without any extra effort.
