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?
