I had trouble finding 8" or larger pvc pipe quickly. So we went with 6" Sewer pipe(cheap thin wall)
we hooked it all up, and started it up, part of the pipe collapsed ( sucked together)
It was still siphoning, but maybe around 60% the flow.
Next day i orderd SDR-35 heavy pipe 6" and set it all up.
it worked great. both siphons were working.
I couldnt believe how much water those 2 6" siphons were taking out.
Lake is about 5ft down, and still going. we had a excavator guy come in that has experiance repairing dams and building them. we are going to plug the pipe with concrete, then compact clay with a mini excavator ( compactor attachment)
Next is the spillway design and estimates. I cant go back to these ,in the dam drain pipes.
between beavers,heavy rains and misc debris floating into it , its to risky...
i Will have pics up of my siphon system and how bad of shape the culvert pipe was it. It was a dissaster just waiting to happen.
