Well Issue - Low GPM Production
I recently had a well drilled solely to irrigate my lawn. Unfortunately, after drilling 418 feet, the well only produces 2 - 3 GPM. The static level of the water is at 116 feet, so I have approximately 300 feet of water in a 5 inch casing. (To make math easy, I'm estimating this is roughly 200 gallons). I've placed the pump 10 feet from the bottom, so I have the 200 gallons in surplus to use. Probably the best solution would be to bury a large tank to hold a supply of water, but prior to going to that effort, I'm thinking of trying the following. Let me know your thoughts:
Design my zones so that each zone uses approximately 5 GPM (not sure how realistic this is with a 3/4 acre lot - haven't quite looked at it on paper yet). This would only cause a 2-3 GPM draw-down on the well. Therefore, I could water 6 zones at approximately 15 minutes each... Then, wait for 100 minutes for the well to replenish... water 6 more zones, etc.
Later, if I decide to bury a tank, I could combine a few of the zones at the valves and it would speed up the watering process.
Any thoughts? Has anyone encountered a similar situation?
