Find out what the local regulations are and obtain a permit for your prospective well. The local division of water resources is in charge of permits, and in most cases you will be able to access the forms online on the division's official website.
Locate a water source. Contact your local authorities to obtain access to water depth charts.
Choose a suitable drilling site. You may want to consult drilling companies, your local division of water resources, hydro-geologists or other experts.
Drill the borehole for the well. Use an industrial drill, preferably with a diamond bit. Drill until you reach the water level, which is usually at 300 feet but sometimes may be deeper.
Install a casing to protect the borehole. Depending on the terrain type, you may need to install a gravel filter pack before the casing.
Attach a polyvinyl chloride (PVC) pipe to the drill and drive it deep into the ground.
Install a pump within the pipe (follow the manufacturer's direction). The pipe's upper end should be 3 feet above the ground.
Fill the pit with soil to prevent contamination. The pipe should be in the middle.
