i am kinda starting the process to install a pump for my pond. i have been using a gas pump on and off, but that is too much trouble. i hope to be able to make a ford across my larger stream soon, and incorporate some type of catch basin for the pump pickup. i need about 15 gallons a minute for the pond to hold its own, but i would like closer to 30 to 40 gallons a minute. the pump will have to lift about 8ft and push water uphill about 35ft. a well drilling friend of mine said the grit it will pickup in the stream could cause a problem for the pump. anyone have any experience with project like this?
