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.

 

If the over-burden is unstable, we secure the borehole and “mud drill” by combining water with bentonite (a natural clay native to Wyoming) and circulating the mixture through the borehole. 

​

Setting Well Casing

T he second step in drilling your water well is “setting casing”. We do this by withdrawing the drill from the borehole described above and lowering six-inch diameter, 1/4 inch thick steel pipe (casing) down into the hole.

​

The most important part of setting casing in your drilled water well is making a perfect seal with bedrock to guard the well from surface contaminants. We pride ourselves on making a perfect well casing seal by setting it at a safe depth such 20 feet beyond the start of solid bedrock. Inadequate or improperly installed casing can expose your well to potentially-harmful surface water.  

​

Tapping Underground Aquifers

After we set well casing, we drill into bedrock (a.k.a. ledge) seeking underground aquifers full of pure and wholesome drinking water. We’re sure to drill beyond veins to protect against sediment entering your well or rock falling into your well and plugging off your water source.

Well Water Flow Testing

Before we leave your property, we conduct simple but accurate water yield tests. Once we confirm well flow and depth, we chlorinate your well per state law. For new construction, we protect your drilled well with a temporary cap until the property is ready for us to install your well pump system. For an existing  structure, we often immediately begin well pump system install and, in some cases, drill a bedrock well and install the pump system in a single day.
