Water Well Drilling is a specialized trade that is becoming more needed as new building construction keeps rising. The main use for this type of drilling is for people building new homes in the country who will not have access to water from the nearest town.
The people who are able to buy vacant land and have a company build a home for them can afford to have a well drilling company come out and get them situated with a water source. This is a need where money should not be an issue.
There are not many of these businesses around, so the ones that are established can stay very busy in the warm months when the ground is good to drill. Permits are probably going to be needed for this, so you, or the company you hire, would want to check with your appropriate county agency.
