    I do some work for a property manager. One of her properties is wanting a sprinkler well. They currently use metered water for irrigation and the water bills are becoming too much for them. The property manager said that she asked some other company about a well and they told her that the water table was in excess of 100 feet and that it was too deep to drill a well. Is this true? I know nothing about well drilling, so I need some help on this one.
    Also, if a well is not possible, are there any other options to keep water costs down yet have an adequate irrigation system? Thanks!

    A lot of wells are washed down in Florida to a shallow water table.

    At 100 feet, you would actually need a real drilling rig, and cast iron well piping etc. In other words, a real well like the rest of the country uses.

    100' is common out here for a well. We are solid rock after about 10'. I believe its around $15 foot.

    It's common here also to hit 100', round here they will charge a base price for the first 100' then a per ft. price from there, you or her need to contact a well company and get an idea of what kind of depth they need to go in that area, any good well driller that's in the area can give you a real good guestimate at the water depth.

    Sure glad nobody in SW Kansas or down in Western OK never told them you couldn't get water from +100'. Our wells here in NE KS run as shallow as 75' to 200'. Avg around here for "sweet" water is about 160. Down in SW Kansas, 200' is a shallow well.

    You would have to go pretty damn deep to get water that would cost you more to pump than to buy from your local water company.

    I live in the land of no wells. BUT since the water table everybody is drilling into extends way beyond your property line and is a limited resource I think you should pay some fee for it.

    100ft is not to deep for a well here in Florida.

    Is this property close to the beach or the water? The freshwater gets deeper as you near the coast, most wells about 2 miles inland or so can be 10 - 30 feet and have plenty of water for a shallow well. A deep well around here is going to be 100 - 300 feet and you will need a company with a real drilling rig to come out and shoot it down. We have limestone for quite a ways so it takes time. A church I cut at had a deep well installed a few years back went down about 300 feet IIRC and 200 of that was through limestone. Cost 3k I believe.

    bah, 100-200 feet are for kids. Some of the aquifers we tap into around here run at 1700 ft.

    How deep is too deep for a sprinkler well?

    When the depth of the required well exceeds the size of you pocketbook... the well is too deep.
