What is a well?

A well is more than a 6" hole in the ground. The top part of the hole is drilled through dirt, sand, and/or gravel. It requires a heavy steal casing. The casing reaches from above the ground into the ledge, where it is sealed in the bedrock to keep out ground water. The casing may 40' or 200' depending on how far down the ledge begins.
The bottom part of the well is simply a hole drilled in the rock until a water-bearing layer is intersected. The hydraulic pressure pushes this water up, filling most of the hole and casing. If water overflows the well casing, the well is called a “true artesian” well.

What if there is no water?

Almost all wells produce some water. If the flow is not enough for a household, we can hydrofracture the well below the casing. To hydrofrack, the well is pressurized with water until additional water-bearing fissures open up, allowing more to flow into the well. In all our years of experience, we have only seen the process fail one time.                                                                

How clean is my well water?

A drilled well taps the water that flows through cracks and strata in the bedrock. Wetlands are primary “recharge” zones for drilled wells. By the time the water reaches you, it has been flowing through rock for many years where it is not exposed to, nor conducive to, the growth of harmful bacteria.

How much water is enough?

The average household uses about 300 gallons of water per day. A well that produces 1 gpm yields about 1400 gallons per day. Most wells in central Vermont produce more than 5000 gallons per day. Almost all wells produce more than 1 gpm.
