Hey guys. Haven't done much in the way of irrigation before but I just bought this house with a 2 acre lawn. I was thinking of irrigating it and using the cistern to supply the water (ithe water is caught from the gutters on the house). I am guessing the cistern is approximately 5000 gallons. Would this work? And what should I be looking at spending for parts / supplies (ballpark)? I am sure there is lots of info I didn't provide. Let me know. Thanks.
