Well Drilling & Pump System: How we do it.
After setting up the drilling machine, we first have to drill with an over-sized bit, through overburden (unconsolidated earth) until we reach solid rock, which usually averages 40-60 feet in depth.
Once we're through the unconsolidated overburden and into the solid rock, we install well casing to provide support to the overburden so that it does not cave into your well. The annular space left around the casing is pressure pumped with sodium bentonite clay, to seal off any surface water from entering your well, eliminating the chances of surface water contamination in your water supply.
We then switch to a smaller bit, which fits inside the casing and we run down through to continue drilling into solid formation, to eventually encounter water bearing fractures, which will supply your well with water. So basically, we drill until we hit water, and continue just until we can ensure you will have an adequate water supply for your usage needs.
The pump system (the system put in place to get water to your home or dwelling) comes after the well is completed. Once the well is in place, the depth is known and so the pump system (pump, pipe, wire, fittings, etc.) can all be sized to bring water from your well at a certain depth setting. For example: If a well is 200 FT deep, we would know which size pump (horsepower and pumping rate) would be efficient enough to supply water from about 180 feet to the point at which it enters the dwelling.
In case you were wondering about the 180 feet, we set our well pumps 20 feet off the bottom so that sediment, which builds up in the well over time, will not enter your pump. If you were to set the pump on the bottom it would essentially become "choked off" over time and would cause total failure of your water system. Along with the pump size selection, comes wire size selection and pressure tank selection.
All is based on footage.
In most cases, our driller can tell you a rough depth in a specific area (subdivision, road, general location) before we do any work, and provide you free estimates so that you have an idea of the costs involved. In most cases, he will also know, specific to the area you are looking to drill, whether there is any difficulty in the process of drilling in the area, and whether there is usually plenty of water in the area or not. A quick phone call or an email will leave you less "in the dark" on these matters.
Worthy of Mention:
Here at Miller Enterprises, we have always been the type of company who ensures that our entire staff has a common value shared: We strive to do things right, in hopes that you will not have to call us back for years to come. Your expenses matter to you, and we are conscious of that...and besides...it costs a company to have to come back to a job as well. That is counter-productive and that is a word that nobody likes!
