Water Well Drilling is safer than other types of wells because the wells can be drilled several thousands of feet deep, which protects them from surface contamination. The water is then pumped from underground for use by water pumps. Drilling can increase the lifespan of a water well for 10 years and up to fifteen years, depending on the pumps used to pump the water. Well drilling usually comes with a maintenance plan to help maintain the wells. You would check with your drilling company for the types of services they offer. There are several different drilling methods such as auger, rotary, down-hole hammer, reverse circulation, and rotary mud drilling. Drilling can be done in the most remote and most difficult areas. The method used will depend on what is best for your location, and will depend on several factors. The objective is to use the lowest cost method, and one that will work best for your project.
