I have a 2" drain in the bottom of mine. In the center i dug down 1' deeper than the rest of it. Its a simple shower type drain with a 90°elbow. It angles up to ground level 9' away with a ball valve at the end. After taking all the big debris out by hand i open it up and it washes all the sediment out. It takes about 40-50gal of water out. Then I'm half way to doing a pwc.
