Before a water well is drilled, the most appropriate location for it must be determined. Property owners planning to drill a water well can evaluate the layout of their land with the intention to maximize well productivity and minimize the possibility of future problems.
The width of a drilled water well is usually only several inches. The submersible pump is located near the bottom of the well. The pump is capable of delivering all the water stored above it, but a steady incoming flow is needed to refill the well. The rate at which a well is refilled is affected by the physical characteristics of your property.
Contour of the land
Rainfall and melting snow add moisture to the soil as part of a continuous water cycle. At some depth beneath the surface, the soil is completely saturated. The point of saturation is referred to as the water table. The water beneath the water table becomes apparent at lower elevations as it eventually emerges from the ground through natural springs.
Rock types in the area
Experienced well drilling personnel are able to analyze the geological characteristics of the area in which you plan to drill. The various types of rocks in the vicinity provide clues about the orientation of the underground water table. In addition to evaluating water sources underneath the ground, you must also consider practical factors above the ground.
Protection from pollutants
The well should be drilled at a spot where rainwater will not accumulate. Running water from heavy rains can carry harmful bacteria. Even though a well casing is surrounded by grout to keep out flowing water, the well is best located so that rain is immediately diverted away.
According to the Centers for Disease Control, a water well should be at least 50 feet from a septic tank. A greater distance would provide an added degree of protection in the event of a septic system failure.
Access for service
Your best location must be accessible by a truck containing a drilling rig. Obstructing trees may need to be cut and removed to allow access. The ideal location for the well is mostly dependent on water quality and productivity and less dependent on the distance from your house or business.
The cost of drilling a well in a productive location is usually less than drilling deeper at a spot with a lower water table. Contact a well drilling company like Schneider Water Services for more information on selecting the optimal location for your upcoming water well project.
