Elements That Help Determine Water Well Drilling Depth, Part 2

In part one of this two-part blog, we went over some of the primary factors that play a role in determining how deep a new water well should be. Water wells can range from about 100 feet deep to 800 feet or even deeper in some cases, and this depends on several different elements in the equation.

At Mike Zimmerman Well Service LLC, we’re proud to offer quality water well drilling and treatment services for your home. Today’s part two will discuss a few additional considerations we keep in mind when determining exactly how deep to drill for your new well.

Water Table Changes

The term “water table” refers to the level below which the ground is saturated with water. It’s a factor that changes regularly within a given year, generally based on seasonal moisture differences and a few other reasons.

In most cases, our contractors will spend time determining the current level of the water table before any drilling begins. They’ll attempt to determine the lowest water table level of the year, using statistical data from several years going back to help them. In many dry areas of Utah, depth for the water table can be wildly different than even a nearby location.

Silting and Draw Rate

One issue that some poorly-installed wells deal with later in their lifespan is called “silting up,” an issue where sand or grit gets into the pump and begins to become a part of the water being pumped up to ground level. Avoiding silting is a common reason why some wells are drilled very deep into the ground, leaving years and years before any issues can arise here.

In addition to depth concerns here, your well drilling experts will also consider draw rate. This is the speed at which the pump draws water from the well – you want a fast enough draw rate to provide enough water, of course, but not so fast that silt or other debris can make its way in.

Surface Contamination Avoidance

Finally, another common benefit of a deeper well is the way it helps eliminate concerns related to bacterial or other forms of surface contamination. This is a two-sided coin, however: The deeper the well, the greater the quantity of rock, soil and other materials the water has to move past as it moves up its casing. It’s possible for contaminants within these rocks to eventually seep into water, as well as minerals that will require softening. Finding the right balance of depth here, one that avoids surface contamination but doesn’t risk deeper forms of the same kind of thing, is why you work with expert well drilling contractors like ours.

Elements That Help Determine Water Well Drilling Depth, Part 1

At Mike Zimmerman Well Service LLC, water well drilling is among our specialties. Using a combination of popular rotary drilling and other methods, we’ll help you tap into unused groundwater found below the ground, then install pumps and all the other required technology to bring it into your home.

We get a number of common questions from our clients surrounding this project, one of which speaks to a very important area: How deep does your drilling penetrate to create a new well? There’s no single set answer here – water wells can range from about 100 to about 800 feet below the ground, averaging about 300 feet deep, but this depends entirely on a number of factors. What are these factors? Let’s investigate in this two-part blog series.

Building Codes and Local Guidelines

For starters, those considering a new well have to do so in accordance with all state and local laws and building codes. If you’re not completely sure of what these codes dictate, you can always check with government offices – though our experts can generally guide you in the right direction here based on our experience.

There are several areas to consider here. For starters, the general standard for water wells requires that well casing reaches all the way to bedrock under the earth, and that said casing is at least 20 feet in length. You’ll also have to think about grouting, sealing needs and well-cap reinforcement, all of which will vary between states and even individual municipalities.

Water Quality Considerations

The general rule of thumb with water underneath the ground: The further down you go, the better the quality the water should be. This is because water nearer to the surface can be more easily impacted by underground critters like moles – for this reason, many states have regulations that require drilling to reach a certain minimum depth to avoid these risks.

Now, how deep you choose to go will depend on a combination of desired quality and capacity for expense. Drilling down deeper than 500 feet may cost a bit more, but that cost could easily be worth it for the improved quality. Again, our team is happy to assist you with the ins and outs of this decision.

Rocky Landscapes

In certain areas where rocks are a big part of the landscape, the distance under the ground at which you reach water can vary widely. If you notice lots of rocks near or under the ground, though, it’s more common for water to be deeper than usual, a consideration you’ll want to factor into your potential costs.
