Water Well Drillers – How Do They Do It?

Water well drillers perform a valuable service. They bring water, life’s necessity, to the surface where we can drink it and bathe in it. Water well is more than just a hole in the ground. Looking for water has a great cost; sometimes that cost is financial, but it has also had its costs in damage to the environment, loss of life or simply in time and labor. Knowing where the water is before you begin will help you save many of these costs.

Up until 200 years or so ago, water wells were dug by hand. This type of well needed to be large enough to accommodate the one or more men with shovels who broke their backs digging down to the water table. The dirt, clay and rocks all had to be removed from the area by hand as well. Once the well was dug, it had to be lined with stones that extended above the surface to create a wall that reduced contamination to the water and injuries to the users. Once the wall was in place, the water excavation can continue to beneath the water table.

Today, the more modern method is to use a pre-cut well ring to line the walls as the well is dug. A hand-dug well is a cheap, low-tech solution to accessing the groundwater. However, there are numerous drawbacks to hand-dug wells. They can only be dug in areas where the ground is suitable, such as sand, clay, gravel or mixed soils. They cannot be dug into hard rock areas and they are usually shallow, most commonly between five and thirty meters. This shallowness means that they can be more easily contaminated or may dry up or become flooded. They are dangerous for a variety of reasons and they require time and physical labor to complete. If these men do not find water where they dig, their efforts are wasted.

Water well drillers have made the job easier and faster but it is still expensive and damaging to your property. Water well drillers most commonly use one of two methods to drill the well—rotary style, or the older cable tool drilling method.

Rotary drillers use a tungsten drill bit attached to a drill pipe. Drilling fluid (mud) is used to flush the broken pieces back out of the hole, and to cool and lubricate the drill bit. Also, the fluid helps to stabilize the wall of the hole and prevent cave-ins that occur before the casing is installed. As the drill intersects the aquifer, the water flows into the hole. If necessary, air hammers are used to help the drill break through the hard rocks.

Cable tool drilling is an older but still common method used by water well drillers. In this method, a heavy bit is attached to the end of a cable that is raised and dropped so that the hole is dug by pounding pressure. This method can bore through any kind of surface and does not need mud lubricants or pumps. It is, surprisingly, less invasive than rotary drilling.

Regardless of the method, once dug, the well is lined with a casing that is usually smaller than the diameter of the drilled hole. This space is filled with cement or a volcanic clay called bentonite to prevent contaminations from surface water. The well is capped with a seal that allows air to travel into the vent, but prevents everything else. Water flows into the well from a screened hole left in the bottom.

As you can see, water well is a very significant thing and before you bring in the water well drillers it is important to know that there will be water where you want it to be. The only sure way of knowing that the water is there is to open up the ground and look for it, but there are some strategies that will give you a good idea.

Do a low-tech property survey. Broad-leafed trees, willows and other water-loving plants will grow where the water is closes to the surface. Look for valleys, gaps, and lower areas, and for any springs on the property. These are all indications of an accessible water table. However, be sure that the area is not prone to flooding.

However, that is not enough. Before having a costly experimental drilling done on your land you will want to know more than that the water is there. You need to know how much and how deep it is. Have a groundwater survey completed. American Water Surveyors has the scientific technology to give you some assurance of water before calling the water well drillers. Those well costs are wasted if the water will not flow to the surface in useable amounts. American Water Surveyors is located in Fort Worth, Texas.

Take the Magic and Mystery out of Drilling Water Wells

Drilling water wells without knowing where the water is can cost thousands of dollars. The typical approach to drilling water wells has been to get out the drills and backhoes, and hope for the best. Sometimes groundwater is found where you hope it will be, but too often for the pocketbook, a second or third attempt must be made; and it is costly. You pay for the drilling services by the foot and sometimes no water is found even after drilling down 2000 feet. The drilling company still bills you for those hundreds or thousands of feet of dry holes in your landscape. American Water Surveyors saves the financial headaches of futile drilling attempts by locating the most likely sources of water from the surface. We can even tell the yield down to gallons per minute.

How does it work? In the past, people had to rely on the ‘magic’ of water-witching or hazel stick divining to tell whether or not there was water in the area they were drilling water wells but now, this effective new method relies on physics and geologically scientific principles for the information. This state of the art technology uses portable discovery and drilling equipment. In simplified terms, the seismic exploration equipment sees the fluid in the rocks and soil. The GF3500 computer-receiver equipment combined with a seismic generator detects electrical signals that are caused by seismic vibration impulses passing through the layers of rock, sediment and soil. A sharp sound pulse is created which moves down through the porous aquifer and causes the water ions to move away from the rock. This causes an electrical impulse which sends a signal to the surface. Each signal transmits information about the depth, thickness and quality of the aquifer to make it clear how much water the area is likely to yield. The depth that the signals are originating from is estimated by using the travel time of the downgoing seismic impulse. Pretty cool, yes? And certainly more reliable than walking along the field carrying a forked stick! Since signals are only produced by moveable water in saturated rocks, this equipment also shows where there is no water, and therefore no need for drilling water wells. Result? No more investing in a dry well. This technology is invaluable for anyone who wants to know how much water and how deep it is before drilling water wells or beginning any other kind of landscape planning.

However, in order to collect the best quality of data possible for drilling water wells the site you choose must be in an area where the soil is good. That is, the first three feet cannot be too rocky. The soil needs to have less than 30% rock in the first three feet. The area also cannot be too close to overhead or underground electrical sources. Electricity that is within 50-100 feet of the site can interfere with the sensitive equipment. Also, the area needs to be accessible to the pickup truck carrying the equipment. With only those limitations, why not hire a groundwater surveyor before you hire the water well drillers?

This technology will help you find the best water available. American Water Surveyors services have been revolutionizing drilling water wells in the United States and other areas as well. All our equipment is in the back of our pickup truck so is easily accessible to all areas. Costs are reduced, time is saved and environmental damage is lessened. Seismoelectrics takes the magic and mystery out of drilling water wells. American Water Surveyors is located at PO Box 164163 Fort Worth Texas 76161-4163. Phone at 877-734-7661.

Water Well Drillers and You

Water well drillers are essential to a desert community or any locale that requires a source of safe drinking water. For ranchers, farmers, homes and acreages or municipalities, there is a great need for a nearby source of water that is not contaminated and produces enough gallons per minute. Of course, well drillers are paid by the foot, no matter if they hit water or not. So unless you want to start an underground silo, the best option before hiring water well drillers is finding groundwater surveyors to take a look at the site with their equipment. They will be able to determine whether a well will produce water or not and how much water that well will produce.

Water well drillers may refer you to an outfit that will survey your site, or they may just start drilling! Be sure to make sure that where you are drilling will produce enough water to justify the cost of water well drillers. Having a well drilled is expensive enough, but if it turns out dry or low-flow, then the well has just become more expensive.

American Water Surveyors is an accredited business with the Better Business Bureau and has achieved an A+ rating in the BBB’s Rating System. They have received no complaints for their work in the four plus years they have been operating.

They work with water well drillers that want to give their clients correct information and excellent service. Using groundwater surveyors prior to drilling will set water well drillers apart from the crowd: it shows that the drillers want customer satisfaction before a big paycheck. Not only that, but the rig employed to make the well will not suffer more wear-and-tear than is necessary.

Golf course developers will find groundwater surveyors to be incredibly useful before hiring water well drillers. The surveyors will be able to find if the site has an adequate water supply for the desired development plan and will determine the volume available and if it is enough to maintain excellent condition after completion.

Groundwater surveyors can save an acreage owner a lot of time and money: they can save the cost of long water supply lines by finding the best place for water well drillers to start, find the best location to start building your home, and find where a well will give the most volume. They can save a homeowner time and money through finding the best place to build a home and a well.

American Water Surveyors are incredibly mobile: all the necessary equipment is stored on their trucks. The technology they use is state-of-the-art and precise to gallons per minute that a potential well could produce. They can be at your site within a reasonable amount of time (distance and schedule permitting) and the savings from finding the proper well site will likely equal or exceed the cost of drilling a well before having the area surveyed. So before hiring water well drillers, find your local groundwater surveyor. Here is the contact information for American Water Surveyors:
