    Finding out Water Table for Dallas Texas

    Hi

    I am planning to acid wash my pool this month (so drain and refill). I live in the Dallas Fort Worth area. Does anyone know how I can determine the water table in my area to see whether this is an ok time for it? I'm planning on it being a 3-4 day process with a chlorine wash and gunite repairs. Thanks for the help!

    Safest method would be to dig a hole near the pool to the depth of the pool and see if there is water in it ... although that is a lot of work.

    Look at the topography around your area...flat? Hills, ditches, ravines? That can give you a reasonable guess sometimes. But, like jbliz said, safest way is to dig a hole...

    Thanks for the help guy! Unfortunately digging a hole is not an option - there are lines and wires everywhere. Can't even plant a tree! The area is pretty flat. Would that mean the table is higher? Is time of the year a factor?
    Thanks again

    Time of year is certainly a factor as it fluctuates with the amount of rain you get. You may be able to contact someone at the county office that may have a better idea.

    Are there any bodies of water or depressions near you (deep drainage ditches, etc.)?

    Contacted the county offices but all they could give me were the water rates. Not much knowledge there. It has been very dry for a couple of years here (water rationing is in effect). Does that make a difference? The closest non-man-made body of water is a lake about 10 miles away. Thanks again for the help!

    Call the local pool builders and refinishers. They will know because when they refinish a pool, they drill holes in the bottom to keep the pool from floating if the water table is up. They will have a feel for what the draining might be in your area at this time of year.

    They drilled rather a lot of holes in my pool when replastering. All of them drained for awhile, then most stopped, then there was a later rush of water that left a few inches in the deep end. Never a lot of water, but usually some. I think the later inflow was from a rain that we had had before the process started, just flowing from wherever the surface exposure was for that layer of dirt.

    Many localities have free utility marking services for homeowners who need to dig in their yard.

    If you cannot, or don't want to, drill your own test hole, then there are likely monitoring wells nearby that could give you a good idea.

    Most local governments have some sort of Department of Groundwater Resources or Well water services etc. that maintain information such as ground water level.

    With a little research, I think that you should be able to find someone who could help. When you contact someone, if they say that they don't know, ask them if they know who would know. There is almost definitely someone who has this information.

    The Department of Public Works or the Health department might be able to help or direct you to someone who can.

    The USGS maintains information that might be helpful. If they don't have the information, they could probably advise you on where to get the information, or who to contact.

    Pool builders, or other builders who dig, might have the information you need. The builder who built your pool should know if they hit water. They might have put in a well point under ground for water control.

    A local residential well driller might be able to help. They could even drill the test hole for you. Companies that do foundation repair could probably help. A professional geotechnical engineering services company could advise you.

    There is usually a stream, pond etc. close enough to help give you an idea. It can be man-made, or natural.
