You may recall that I bought a wedge wire filter from you some years ago. I'm still working on that hydro project. The pond dredging is for my original hydro setup which is still limping along. I tried using a siphon for draining the pond some years ago but had a very hard time getting it started, only succeeded once out of about 50 tries. I was using 4" corrugated plastic drain hose. Kind of left me discouraged about using a siphon. --Douglas Rupp ----- Original Message ----- From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, August 19, 2004 8:51 AM Subject: Re: [microhydro] Hydro intake pond dredging Douglas, Rather than trying to educt and use a pump, let nature do the work for you. Get some spiriflex pump suction hose and get a siphon running over the top of the dam. Then rig up a line of floats to carry the hose or pipe. Put a stinger down and suck up the mud to be put over the top of the dam. You can use el-cheapo plastic pipe to move the material from the far side of the pond. It takes a bit of practice but can learn to use the stinger without plugging it up. The spirraflex hose will allow you to easily start the siphon, this cannot be done with rigid pipe. To make it very simple put a valve on the end of the siphon pipe so you can easily fill the pipe to get things running. I have seen big siphons suck rocks the size of bowling balls up and over the top of the dam. In the beginning of the operation it is sort of like being a kid again, moving water is fun. Drop me a line if you need more insight. Bob Robert K. Weir P.E.
