Need to see if any of you have any good ideas. We live on the side of a mountain, and we catch our water from a spring about 900' above the house on the side of the mountain. The water comes down a small waterfall and we catch it in a wooden box about 3' square. There is a 2" pipe coming out of the box runing toward the house. We need a good, foolproof way to keep the debris from clogging up the catch. Right now we cover the wooden box with 1/2" wire, then screen, and roofing tin on top of that. Water can still run under the roofing tin, so some of the debris washes across, but some goes in and clogs the end of the pipe. (The pipe has a shower drain over it also.) We have heard there is a way to let the water in that will make it a self-cleaning system. Don't know how this is supposed to work. DO any of you have any ideas? We would appreciate any help. We have been fighting this battle for 4 years. BTW - We also have a commercial water filter system at the house to clean out anything that might be in the water, and we have the water tested regularly for safety. THANKS!
