My river is powered by 4 HP of two electric pumps feeding a three inch PVC for about a hundred feet and fifteen feet uphill. Lots of water, great flow, but: I now see the potential to feed the current pumps' output into two large Honda powered three inch water pumps, like 10 HP each, each pumping out to its own 3 inch pipe. I hope that would provide sufficient flow that the waterfalls would act as rapids for when someone wants to kayak. Do you think that could work? Or should I plan on renting a forty horse diesel pump for those special occasions?
