Thread: Looking for Some Input

I got a hold of this double washboard sink and I'm wanting to use it for a fish cleaning table I live in the country and can run the run off water under ground to the woods so should i USE 3 inch or 4 inch pipe also should i use the preferred pipe once its under ground that way some of the water will seep out on its way to the woods

also any input on the base for the sink would be great im thinking about using a old 4 x 6 i have for the legs and making it only as big as the sink because the wash boards on each side are big enough to use for cleaning fish
