    Default water lawn from lake

    Do you guys think it is cheaper to pay for water to water your lawn, or cheaper to pay the electicity to run an electric pump to siphon water from a nearby lake to water the lawn? I'm not asking for any negative comments here, just the facts.
    I suppose I could do the math to figure it out, based on the power used by the pump for x amount of time, versus how much I would pay for x gallons of water, but wondered if anyone knew offhand?

    Figure ten to one, or even more, for comparing city water cost versus pumped lake water.

    After you decide how much water you will be using, you might run your system by here for suggestions before you buy the hardware. It is easier to get the right stuff to start with than to try to make a mismatched system work.

    I was thinking I could plug the pump into one of those electronic timers that you can set (i already have an outdoor one). So basically, the timer would turn the electricity on to the pump, which would then start pumping water to I'd say about 3 sprinklers. I'd probably run them around 2-3 times a day for 20 minutes.
    The only thing I am uncertain of is whether or not the pump would need primed every time it starts up? If that's the case then this is useless to pursue.

    So far as I know, there are no irrigation controllers you can plug a pump into. Your location figures into these answers, so please tell us what state you live in.

    Live Virginia. I was going to hook up the pump directly to lawn sprinklers. I'd probably run a 1" line in the lake, and then have it tee off into maybe three sprinklers.
