How to plan to drill a well?

A well is a man-made hole dug into the ground to get to a liquid. The most commonly sought liquid is water: About 97 percent of the worlds fresh water is found in underground aquifers, and some 15 million American homes have water wells. Water wells may be dug simply to monitor water quality or to heat or cool, as well as to provide drinking water when treated. Drilling a well may be done in one of several ways, as described below, and there are things to consider before drilling a well.



Consider the costs and benefits of drilling a well against piping or shipping water in. Drilling a well involves a higher initial cost than connecting to a public water supply, as well as risks of not finding enough water or water of sufficient quality and ongoing costs to pump the water and maintain the well. However, some water districts may make residents wait years before they can be connected to a public supply, thus making well drilling a viable option where there is enough groundwater at a reasonable depth.



Know the specific location of the property where the well is to be drilled. You will need to know the section, township, range and quarters to access land and well records through your states geological survey or from your State Water master.



Find out what previous wells have been drilled on the property. Geological survey records or state well drilling reports will record the depths of previous wells in the area and whether or not they found water. You can access these records in person, by telephone or online. These records can help you determine the depth of the water table, as well as the location of any confined aquifers.

Most aquifers are at the depth of the water table, these are called unconfined aquifers, as all the material above them is porous. Confined aquifers are covered by nonporous layers, which, although they push the static water level above the top of the aquifer, are more difficult to drill into.



Consult geologic and topographic maps. Although less useful than well-drilling records, geologic maps can show the general location of aquifers, as well as the rock formations in an area. Topographic maps show the surface features and their elevations and can be used to plot well locations. Together, they can determine whether an area has sufficient groundwater to make drilling a well viable.

Water tables are not uniformly level, but follow ground contours to some extent. The water table is nearer the surface in valleys, particularly those formed by rivers or creeks, and is harder to access at higher elevations.



Ask people who live near the property. Many older wells have no documentation, and even if records exist, someone who lived nearby may remember how much water those wells produced.



Get assistance from a consultant. Your states geological survey personnel may be able to answer general questions and direct you to resources beyond those mentioned here. If you need more detailed information than what they can provide, you may need the services of a professional hydrologist.

Contact local well drilling companies, especially ones that have been established for a long time.

A Dowser or Water Witcher is a person who uses willow branches, brass rods or similar items to search for water. If you want, you might employ one to help you find a good site.


PQWT water detector device can automatically form the profile map and curve graph in the instrument, that means you can get the drill position as soon as finished measurement.

It can save your lots of cost and time.
