I had a 100 ft of water in my well and drew mud last year after the 3rd year of severe drought. Yes I'm thinking about rain water catchment. Water table is back to normal this year with an abundance of rain. Had the strangest dry September I can remember this year though.We are over an aquafir. Our well will never run dry.
What kind did you get?East TN has been in a mild drought this year, no problems.
We live around so much water I don't think we will ever have a problem.
We just installed a deep well hand pump so we will still have water if electricity goes out. Only cost a $250.00 ish.
