The actual drilling procedure can be broken down into five steps:

1. An 8 1/2" diameter hole is first drilled into the soil down into bedrock.

2. A 6" diameter steel pipe ‘casing’ is then placed into this hole (see diagram). This casing is fitted with a ‘drive shoe’ which, when driven into the bedrock, forms an effective seal, keeping out dirt, stone and surface water which could carry contaminates.

3. Drilling continues into bedrock until a sufficient water supply is reached. The drilling may vary from 30 ft. to several hundred feet, depending on geological formations.

4. At this point, the constant rate of flow is determined — represented by gallons per minute. Together, the G.P.M. and depth of the well (which acts as a reservoir) along with the known demand or usage, yields the formula for a successful well.

5. With the drilling completed and yield determined, the last step is to select and install the proper pump, tank and controls. The pump size (a submersible type, located in the well shaft) is determined by the depth of the well, the G.P.M. and the static water level. The water tank is the only piece of equipment besides a control box that is actually installed in the residence insuring quiet operation. With this final step all is ready for the plumbing to be connected to the water tank.
