    Hey guys, I need some advice. I would like to pump water out of a 15 acre lake that is behind my house for my irrigation system. I'll need to run 750 ft of pipe from the lake to where my current county water ties in. Plus this will be all up hill. I have 6 zones with 4 to 6 K2 large sprinkler heads. I would like to get 40 psi to the heads. Not sure if this can be done with out breaking the bank?

    Thanks,

    It can be done. The real question is should it be done. Where are you locted, how expensive is city water there, are there water bans that are making it tough to keep your lawn green.
    So lets first discuss if it should be done.

    How far uphill? What is the flow into the current system?

    Hey guys, I spent $500 on water last month and watered 4 times for a 1/2 hour per 6 zones.

    How do I determine the flow to the current system?

    Thanks,
    Tony

    If you are buying water, do you have a water meter?

    If you are in Cumming, Ga send me a PM. We put pumps on Lanier all the time. It will depend on your elevation change as to how much water and pressure you can get. Expect to spend around $2-$3K

    If you have a wristwatch to go along with the meter, you can calculate the flow in your sprinkler zones.

    Thanks Wet Boots. So is there a calculation that is used to determine the water flow? Or do I just note how many gallons per minute for each zone? When I find out the water flow for each zone, how do I use that number to see if pumping from the lake will work?

    Eartmgtsolutions, I have between 4 to 6 K2 sprinkler heads with 2.5 GPM nozzles over 6 zones.


    Thanks Again,
    Tony
