backyard well, good investment?

my question is, Will a well for my half arce will be a good investment?

I will most likely have brakish water, high enough % to get a filtering system.

I did some research, i can just buy the housing unit and filters for it (using the well pump presure system) and buy a 50 dollar salt monitor so i can replace the RO filter.... or buy a system for about 1600 dollars (300 gallons a day)

you think my plants (30 tropical trees) will benifit from it, and save me money (vs city water)?

I am kind of worried about the city water chemicals they use to purify the water .

Plus, I think it will save my money, watering my front and back yard since I live in south texas, zone 9 (almost 10) hehehehe

Cant help re the well being an investment, but if you have done your research and feel it will repay the cost of city water within say ten years, then I would go for it, anytime after that, then a) you might have moved home and b) we should all think about trying to save water, over here in UK there are a lot of folks setting up water butt's where the rain water from the gutters is run into the butt's to preserve water, I also know some folks who reuse the bath water on their gardens for the same reason, so good luck, hope all works out good for you, but do as much research as possible in-case it turns into an expesive toy, we all have these in our garden sheds eh. best wishes.

i would think it could be very expensive. dig the well yourself or hiring someone to drill.
if you have an electric pump that will cost, or you could buy a windmill, they're expensive also. you may not be able to pump it fast enough and have to have a tank to hold the water. don't forget electricity cost.
this house i moved into a couple of years ago has a well house, and a pumphouse from the pond that they had the outside faucetts connected to. of course both pumps were broke. but since the outside faucetts were connected to pond, i figure it must be a shallow well and doesn't have much for recovery time. i had the outside faucetts connected to the city water. as dry as it was a couple of years ago and the pond being down i seriously considered hooking up the well house to fill the pond!

I think this is a very interesting & pertinent question! Would how deep your water table is make much of a diff? Would it be possible to use a solar powered pump to bring it up to a holding tank?

yes how deep does make a difference. as far as the solar panels for the pump, i don't know, but it might take the whole half acre for the solar panels to generate enough electricity to power the pump. If we could eliminate taxes and regulations on our resources, we could afford them and not have to resort to measures to try and stay ahead of the t&r eight ball.

You need to get a professional into find your water table and how deep it is from your surface area, then you need to drill down to get to the water to find how much water there is as too little, you wont get it at all, you then need plumbing work before you even need a pump, you need to test for pressure and then build the well so this ain't for the faint hearted,
you need the overall cost first to make sure you will really save money in the long term, also, you will have maintenance costs to add to that as the well needs serviced each year to make sure it is working properly, so I would get the costings done first before I bought anything, once the driller finds the water table, he then has to drill way below that to allow for the well to fill up enough for the pumping system to work, that is layman terms, but it is a bit more work than I have said. good luck.
