+Drill larger holes (about 1/4") on the bottom of 2 tubs. Space about 5cm apart. These 2 tubs are the interchangeable top layers of the worm farm. Both will drain liquid down to the 3rd level (and also letting the worms move up and down).

+**Step 3**
+Create your drainage system on the 3rd level. You could just drill a hole and let the liquid drain into a bucket. However, worms can be prone to escaping, so you're better off creating some kind of small drainage system which would make it harder for them to crawl through. Either way, you need to check the 3rd level occasionally - to remove anything clogging the drain and maybe helping a few stray worms back to the top 2 levels.
+So back to the design. I drilled a small hole in the side of the tub, and inserted a small tap with a threaded end which I closed off with washers and bolts to make it water tight. The tap can be closed off however it's best to leave it on, letting worm tea drain into a bucket below. It's good to use the tea when it's fresh, so seeing it in the bucket reminds you to put it on the plants. Just a useful tool for not forgetting!
