I have a question that I have been unable to find the answer after a substantial time. Here goes. I have 140’ of 10” construction drain through the bottom of my dam. The 10” pipe has been reduced to an 8” UD slide gate valve. The problem I’m trying to solve is the size of the cage/guard that will go at the bottom of the pond around the UD slide gate valve that is constructed of cutting board like material and stainless steel springs. I understand when RAH stated that surface is your friend. Does anyone have suggestions on what size of cage and shape the openings should be to allow the passage of leaves and sediment to pass through the grate openings in order for the construction drain at the bottom of the pond to not clog with leafy debris? Any help is greatly appreciated. Thanks, Heppy
