Once the well is dug and water is located it must be cased to prevent the hole from caving in. Casing can be steel or PVC depending on if you are drilling through rock or clay. The maintenance then depends on the system. Electric pumps and seals on windmill pumps can fail after a few years and must be replaced. There is usually a minimal amount of actual well hole maintenance unless it plugs up due to sand or other debris.
It is wise for you to maintain your major parts regularly for long life of the rig.for more knowledge, please keep looking our website:www.rejeedrilling.com
