Be sure to screen the input(s) somehow.

What kind of flow will it handle?

From the looks of it though maybe cheaper to buy one pre-made than all those 1-1/2" PVC fittings.

the whole thing cost maybe $20 to build, excluding the ball valve. the ball valve would make it like $30 or something.

for the input screens i put gutter guard on it. the intake pipes on the pic are actually too short. im not sure what kind of flow it will handle. anyone know?

I'm not sure how this will act due to the siphon. But a simple standpipe overflow won't handle much because of the lack of pressure driving the water. Same holds true with tanks drilled towards the top and using a bulkhead fitting for the overflow. Move that hole towards the bottom and add an "L" & riser and it really does'nt help increase the flow since there's still no water pressure driving it into the standpipe.
