Should a Drinking Water Well Be? (Homeowner’s Guide)

There are plenty of benefits of owning your own private well.

You’ll pay less for your water, increase the value of your property, and have unlimited access to as much water as you could want.

When you’re looking at installing a well, the depth of the well is an important consideration to make.

Your well needs to be deep enough to reach an underground reservoir known as an aquifer, which will collect water that pumps up to the surface. Located at the bottom of the casing is a seal, which will prevent pathogens from entering the groundwater through the bedrock.

If you’re at the point of installing a dug well, it’ll need to be between 100 and 500 feet deep. Sometimes a well water source may even reach up to 1,000 feet deep.

Why such a wide range?

The actual depth of the well will depend on several things, which I’ll be looking at in more detail in this article.

Factors Affecting How Deep a Residential Water Well Needs to Be

Depth of Aquifer

Wells get their water from underground aquifers – or pockets of water inside the bedrock.

Your well needs to be deep enough to get access to this water, so the depth of the well you need depends on how far below ground your aquifer is.

Typically, well drilling needs to reach at least at the 300-500 deep feet range to hit the bedrock, though on some occasions, a well may even need to reach 1,000 feet.

See this article to find out more information about aquifer depth in your region.

Risks of Surface Contamination

Generally, if your well is properly constructed (i.e. it’s solid, durable and protective against harsh environments), it’ll provide better protection the deeper it’s installed.

If you have a longer well depth and more well casing, water will take longer to flow from the aquifer to the well pump.

This longer traveling time gives a higher likelihood of any bacteria and other health-harming contaminants dying off or getting trapped in soil along the way, reducing the risk of contamination of the well’s surface water.

Geology of Bedrock

The geological characteristics of the bedrock below your property will have an impact on the location of the aquifer, which will in turn affect the well depth.

Rock formations that are low-yielding will likely require especially deep well drilling, to allow the well to act as a storage chamber for groundwater.

The geology of the rock your well will be drilled through may also determine the size of the well, which will have some effect on its depth.

Water Quality

Certain areas in the US have “cased off” zones that wells cannot be drilled into because of poor water quality.

In this case, you may require a deeper well depth to avoid these zones and prevent dangerous contamination of your water.

Your well driller/drilling company or local authority should be able to provide information about your water supply, including any changes in the depth of the water table and the quality of your ground water.

If you’re drilling a deep water well for better water quality, make sure to factor in plenty of time – it usually takes a full day to get the well, cap and casing properly installed, and an extra day to install the well pump.

Seasonal Fluctuations of the Water Table

If your local area’s water table fluctuates with the seasons, you might have to drill your well much deeper than anticipated to be sure you always have access to a groundwater supply, regardless of water levels.

Again, you can search for information about your water level, and how it may be related to the required diameter of nearby wells, online.

Governmental Regulations

Depending on the state you live in, there might be certain regulations you have to follow relating to well depth. Be sure to check out these specific guidelines and rules before drilling a well.

Generally, you’ll have to have a casing that reaches at least the 20 foot mark, which typically needs to reach the bedrock. You’ll have to properly seal the outside of the well casing, too, to stop sand and sediment from getting into the system.

Remember, how deep your well is will affect a number of drilling factors, such as cost, pump placement, the well’s diameter, water levels, and perhaps even water yield (in gallons per minute). A shallow well will naturally cost less to be drilled than deeper wells, and drilling a shallower hole into less rock will take less time.

In your search for a company to drill your well, look for one that has extensive experience in the industry, and you shouldn’t go wrong. Keep in mind that the majority of companies charge per foot drilled, so depending on the above considerations, it could be an expensive job. Learn more about finding a contractor at wellowner.org.

Frequently Asked Questions About how deep must wells be drilled in order to collect water?

If you have questions that need to be answered about the topic how deep must wells be drilled in order to collect water?, then this section may help you solve it.

How far should a water well be dug?

The deeper a well is, the better the water quality will be; the average depth of a residential well is between 100 and 800 feet deep; some wells are even 1,000 feet or deeper.

How far down must I dig to reach water?

Well Depth Is Important Finding high-quality water requires digging at least 30 feet below the surface; however, finding better water that is safe for your family to drink requires digging even further.

Can shallow wells go very deep?

Types of wells Driven wells are created by driving pipe into the ground, and they are shallow (roughly 30 to 50 feet deep) and continuously cased. Driven wells have a large diameter, are shallow (about 10 to 30 feet deep), and are not continuously cased.

What qualifies as a deep water well?

Deep wells can reach hundreds of feet below the surface, while shallow wells are typically used for water that is less than 25 feet below the surface.

Can you dig a well anywhere to get water?

You can drill a well almost anywhere, but watch out for local regulations (and pollutants) by asking The Builder.

How long does it take to drill a water well that is 100 feet deep?

It typically takes 1 to 3 days, occasionally longer, to drill a well, depending on the weather, ground and water depths, and drilling conditions.

Can you drill without finding any water?

Finally, despite our best efforts, water well drilling occasionally fails. If you drill deep enough, you will eventually find water, but in some locations, this water may be salty.

If you delve far enough, will you always find water?

So, if you dig deep enough down into the Earth’s crust, you’ll undoubtedly find water, but no one realistically wants to drill straight down into the center of the Earth to find water. This groundwater may be the result of stray oxygen and hydrogen atoms being pressed from rock minerals.

Shallow wells have a dry spell.

Shallow, hand-dug wells, for instance, are frequently the first wells to dry up during drought. Although deeper wells may be slower to suffer from drought conditions, they may also take longer to recover after a drought has occurred. As a result, shallow wells are typically more susceptible to drought than deeper wells.

Do deep wells become dry?

It depends on a lot of variables, but generally speaking, the majority of modern wells are drilled deep enough so that they shouldn’t ever “run dry” in their lifetime.

How long is the lifespan of a water well?

2. How old is the well? Drilled wells typically go down 100 feet or more, with a lifespan of 30 to 50 years.

Are deeper wells better for water?

In fact, properly constructed deep wells typically offer a much higher level of protection from bacterial contaminants near the surface because there is a longer path to the surface, making their water tend to last longer and require less monitoring for quality.

Is it worthwhile to dig a well?

Drilling a private well is a significant investment, but if you live in a rural area or an area with poor water quality, it could increase the value of your home, so it may be worthwhile to install a well, depending on your needs and budget.

What is the price of drilling a well?

Prices range from,750 to 5,300 for a full system and installation, which includes drilling, a pump, casing, wiring, and other expenses. Total costs are largely influenced by the depth and diameter of the well.

Wells never dry up, right?

When the water table, or top surface of the groundwater, drops too far for a well to reach it, groundwater depletion can also result in wells running dry, leaving them figuratively high and dry.
