Water Wells 101 ~ how a well and pumping system work
Water from artesian rock wells comes from surface water that has percolated deep down into fissures in the bedrock, purifying itself as it travels through the topsoil, boulders, sand, silt and glacial material. A Cushing & Sons drilled well is sealed to protect your well from surficial contaminants that could otherwise enter your water system. These contaminants include such things as waste from farm and domestic animals, leach fields, fuel oil, surface water, chemicals and road salt.
Because this seal is so critical to protecting your artesian well from these and other pollutants, Cushing & Sons guarantees the seal in writing.
We also provide a 5-year warranty on pumps and pressure tanks as well as a 1-year “turn-key” warranty on all parts and workmanship.
Location of the well
Numerous factors affect location and the cost of a water well. These factors include geological conditions, topography, location of driveways and other structures, plus local, state and federal regulations. Cushing & Sons is a third-generation company. Because we have drilled so many wells in NH, VT and MA, we have an enormous amount of data plus the intuitive experience to help locate your well on your property to maximize its delivery of water to your home or business.
Basically there are four important considerations for siting a water well:
1. Where there is ground water
2. Away from sources of contamination
3. Convenient to power and the building being supplied water
4. Accessible for drilling and pump installation
Correct water well design and casing installation is important to protect against contamination risks. Old and abandoned wells can pose particular risks and such wells must always be decommissioned and sealed by a professional.
Fast, efficient drilling
Cushing & Sons uses modern, powerful pneumatic hammer drilling equipment. Usually we are able to complete the drilling in one day. As a result there’s no waiting nor tying up your yard or work site.
Getting water from bedrock is accomplished by creating fractures in the bedrock. Our standard equipment delivers up to 350 lbs/in fracturing power. This will normally yield sufficient water yields. However, when it’s necessary to increase water yields, a technique called “hydrofracking” is employed which delivers up to 5,000 lbs/in pressure. This opens and cleans sediments from existing fissures and creates larger fractures in the bedrock to increase water flow into the well. Hydrofracking can also be completed in one day.
