Custom Washout tank

[BP]

So I live in amish country and I am working with a amish company to build a custom all aluminum washout booth. It will be a dual tank for a clean side and a dirty side.
But still looking for any good ideas.

So please post pic of your big washout booth!

Thanks.

Someone on the forum wondered why the drains are at the back, and not the front of the washout booth.  I had a chance to switch my drain to the front and now I don't get nearly as much back spray from the accumulated water at the back.  My booth is small.  On one that large it might not be as helpful.
