DRILLED WATER WELLS
Solid bedrock commonly known as "ledge" lies underneath nearly all of the beautiful New Hampshire and Maine landscape. This layer of rock contains cracks and veins filled with water. We tap these openings to create bedrock water wells.
Initial Well Drilling
The first step in creating your bedrock well is drilling an eight-inch diameter hole down through the over-burden (all the material that lies above bedrock including topsoil, sand, gravel, clay, etc.). We then drill ten to twenty feet into that solid ledge.
Setting the Well Casing
The second step in drilling your well is “setting the casing”. This is done by withdrawing the drill from the hole described above and lowering six-inch diameter metal pipe known as casing down into the hole. If the over-burden is unstable, we secure the borehole by “mud drilling”. This process entails combining water with bentonite (a natural clay native to Wyoming) and circulating the mixture through the borehole.
The most important part of setting the casing in your drilled water well is making a perfect seal with the bedrock to guard the well from surface contaminants. We pride ourselves on making a perfect well casing seal by setting casing at a safe depth—typically 40 feet—for a total depth of 50-60 feet into ledge. Understand that without adequate casing, broken bedrock can expose your well to harmful surface water.
Tapping Underground Aquifers
After we set the casing, we drill into the bedrock (a.k.a. ledge) until we tap into an underground aquifers full of pure and wholesome drinking water. We’re sure to drill beyond veins to ensure that if over time any sediment enters the well, it won’t plug off your water source.
Well Water Flow Testing
Before we leave your property, we’ll conduct simple but accurate water yield tests. Once we confirm well flow and depth, we will chlorinate your well per state law. For new construction, we will protect your well with a temporary cap until the property is ready for the the pump system install and then replace it with a permanent water well cap. For an existing structure, we typically finish all well pump work, including installing a permanent well cap, once drilling is complete.
