How deep is an average well?

In general, private home wells tend to range from 100 to 500 feet in depth. However, they can be much deeper than this in some cases. There are even some wells that go past the 1,000 foot mark. The average well depth in your area will depend on several factors.

Do deeper wells mean better water?

Confession—The deeper the well doesn’t really guarantee you will have more water volume or pressure. If you have a shallow well, it means that your water source is relatively close to the ground’s surface. Shallow wells typically are less expensive to drill because there’s less labor and fewer materials involved.

How deep is a deep well for water?

Most household water wells range from 100 to 800 feet deep, but a few are over 1,000 feet deep. Well yields can be increased by fracturing the bedrock immediately around the drill hole and intercepted rock faults.

What is the difference between shallow and deep wells?

Shallow wells are generally for water less than 25 feet from the surface, and deep wells can go down hundreds of feet. Wells use pumps to draw water up to the surface. Because shallow wells don’t have a lot of room, their pumps are above the ground, usually inside a well housing.

Does well water ever run out?

When a well “runs dry” it doesn’t mean that the well will never produce water again. Aquifers can recharge through a combination of more precipitation and less pumps pulling water out of that aquifer. Sometimes wells can run dry permanently, but that is quite uncommon.

What is a good depth for a well?

For drinking water wells it’s best to be at least 100 feet deep so that surface contaminants cannot enter the well. The average well depth for private homes is between 100 to 800 feet [2]. You may need a deeper or shallower well if your area has different geology than another region of the country.

Can you drink well water?

Possible health risks of drinking groundwater and well water

Typically, groundwater is naturally clean and safe to drink. Because the soil on top acts as a filter, groundwater is usually free of micro-organisms that may cause disease.

How far from the bottom of a well should the pump be?

Pumps should never be set directly at the bottom of a well. It is usually best to place the pump 10 to 20 feet up from the bottom of the well.

Can you dig a well yourself?

Drilling a well by hand is a lot of work, but it can be done with the right equipment. Whether you’re looking to drill a shallow or deep well, this skill is perfect for those seeking self-reliance. Wells are normally drilled on private land where city or rural water isn’t available.

Is 300 ft a deep well?

Throughout New England, water is often found at about 300 feet, but wells for household use usually range from about 100 feet to 500 feet deep. There are some places, however, where a well can be more than 1,000 feet deep.

Will you always find water if you dig deep enough?

The Deepest Drilled Hole on Earth

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

Can a well be too deep?

The Range. In general, private home wells tend to range from 100 to 500 feet in depth. However, they can be much deeper than this in some cases. There are even some wells that go past the 1,000 foot mark.

How do I know if I have a deep well?

If it is small diameter, such as 1-1/4” PVC, that would indicate it is a shallow “well point” as they are called. If it is 2″ or above, it very well could be a deep well. Larger casings may also be shallow wells. Some of the largest diameter wells are very shallow (bored wells).

How much does a well cost?

Drilling a residential water well costs $25 to $65 per foot or $3,750 to $15,300 on average for a complete system and installation. Prices include the drilling, a pump, casing, wiring, and more. Total costs largely depend on the depth drilled and the well’s diameter.

How do I find out how much water is in my well?

Multiply the length of water column in feet by the gallon volume per given diameter. For example, a 4-inch-diameter well has 0.65 gallons of water per foot and a 6-inch diameter well has 1.47 gallons per foot.

How far can a 1 hp pump push water?

A 1 HP sump pump has significant vertical and horizontal reach, making it ideal not only for residential homes but also for commercial units. These pumps deliver an average of 19 GPH and can lift water from wells that are 200 feet deep.

What kind of pipe do you use for a well?

PVC and Poly pipe will hold up very well in harsh water conditions. When it comes to installation, Galvanized and PVC pipe are simple, predictable, easy to install, and easy to service. PVC pipe is also lightweight. Poly Pipe, as I mentioned previously, is not recommended at a depth below 100′.

How many years does a well last?

The average lifespan of a well is 30-50 years, although they can last longer or shorter depending on different circumstances. If the well you are buying is over 20 years old, you should at least factor in replacing the parts that commonly fail into your home buying budget.

Why does well water smell?

Hydrogen sulfide gas (H₂S) can give water a “rotten egg” taste or odor. This gas can occur in wells anywhere and be: Naturally occurring – a result of decay and chemical reactions with soil and rocks. Produced by certain “sulfur bacteria” in the groundwater, well, or plumbing system.

Will my well run dry if I fill my pool?

If it has a high flow rate, the well can most likely fill a pool, but with a low flow rate, it may run dry. You should also consider whether you’re sharing the water table with neighbors and whether you’re currently in a drought.

How fast do wells refill?

In ideal conditions, a water well will refill at five gallons per minute. It takes two hours to fill a 600-gallon well. Not all wells exist under ideal conditions. There are several factors that can speed up or delay the time it takes to refill.

Why is my well water GREY?

Your water can appear cloudy, white or grey when tiny air bubbles get trapped in the water. They’re not harmful and should clear pretty quickly. If you fill a glass with water, you should see the water clear over a minute or so. The water will start clearing from the bottom of the glass.

What are the disadvantages of well water?

• Hard Water and Scale Buildup.
• Harmful contaminants such as bacteria, lead, and arsenic.
• Pumps need to be replaced every 10 or so years.
• Bad taste.

How do well drillers find water?

If there are no wells in the area, or not enough information is available on existing ones, the hydrologist may contract with a well driller to put down some test holes. At these holes a pumping or aquifer test will be conducted. These tests indicate the water-bearing properties of the aquifer tapped by the well.

Can you build a well anywhere?

The simple answer to Connie’s question is yes. You probably can drill your own well on your property. You, of course, would have to contact your local building department to see if there are any regulations that must be followed.

How drill your own water well?

How deep is the groundwater table?

Groundwater may be near the Earth’s surface or as deep as 30,000 feet, according to the U.S. Geological Survey (USGS).

How do I find the water table in my area?

1. Call your local County Extension Office. It may have statistics for the average annual water table level in your area. …
2. Look online. Check out the website for your local Water Resources Office. …
3. Dig. This is the most reliable way to find the water table level on your land.

How deep is the saturated zone?

The saturated zone extends downward from the capillary fringe to the depth where rock densities increase to the point that migration of fluids is impossible. In deep sedimentary basins, this may occur at depths of approximately 50,000 feet.

What is the deepest water well ever drilled?

The Kola Superdeep Borehole was just 9 inches in diameter, but at 40,230 feet (12,262 meters) reigns as the deepest hole. It took almost 20 years to reach that 7.5-mile depth—only half the distance or less to the mantle. Among the more interesting discoveries: microscopic plankton fossils found at four miles down.

How often should you disinfect your well?

Homeowners with private wells should have their well water tested every 3 to 5 years for some contaminants, including bacteria. If these tests turn up positive for bacteria, chlorinating the well may be a way to resolve the problem.

How much do well pumps cost?

How much does it cost to replace a well pump? The average cost of replacing a well pump is between $900 and $2,500. The cost varies based on the well size, materials used, and installation required. For example, replacing a shallow well pump will cost less than a deep well submersible pump.

Why am I getting dirt in my well water?

The most common cause of dirty well water is simply a broken well pipe that is allowing dirt and surface run-off water to enter the well water. This can leave the water with an odor, bad taste and dirt in the bottom of your drinking glasses.

How do wells provide clean water?

As water is pumped out, water from the surrounding aquifer seeps back into the well borehole. Modern wells have a casing or pipe in the borehole that is grouted and sealed at the surface, and also extends above the ground surface, to prevent contaminated surface water from polluting the well.

How do you maintain a well?

Keep hazardous chemicals, such as paint, fertilizer, pesticides and motor oil away from your well. Periodically check the well cover or well cap on top of the casing (well) to ensure it is in good repair. Always maintain proper separation between your well and buildings, waste systems, or chemical storage facilities.

What is the size of well?

Water wells typically range from 3 to 18 metres (10–60 ft) deep, but in some areas can go deeper than 900 metres (3,000 ft).

How shallow is a shallow well?

A shallow well is a hole which has been dug, bored, driven, or drilled into the ground for the purpose of extracting water from aquifers near the ground surface. A well is considered to be shallow if it is less than 50 feet deep.

How many gallons is a typical well?

The typical 6-inch diameter well will hold approximately 1.5 gallons of water per foot of casing. The height of the water above the pump when it is not operating, multiplied by the gallons of water per foot of casing approximates the amount of available storage within the well casing.

Is 1.5 gallons per minute a good well?

The Water Well Board suggests that the minimum water supply capacity for use inside a home should be at least 600 gallons within a two-hour period, or about 5 gallons per minute for 2 hours.

What is a good water well yield?

A well yield of 5 gallons per minute of sustained flow (measured over 24 hours or over 5 hours in some standards) is considered by most authorities as adequate for a one family residence.

How far can your well be from your house?

Any contamination in your neighbor’s well can travel into your well. Some activities legally require more than a 50-foot zone of protection. As a general guidance, personal drinking water wells should have a minimum horizontal distance of at least 10 feet and preferably 25 feet from such boundaries.

How deep can a 1/2 HP well pump go?

A two-line jet pump can typically raise water from depths of 30 feet to 80 feet, and at water delivery rates of 4 gpm (for a 1/2 hp 2-line jet pump serving an 80 foot deep well) to 16 gpm (for a 1 hp 2-line jet pump serving a 30 foot deep well).

How far can a 3/4 HP pump push water?

3/4 HP Submersible Sump Pumps

A 3/4 HP pump has a pumping capacity 20 to 25 percent more than a 1/2 HP sump pump has. A pump of this size can handle a high vertical lift of 20 to 30 feet and/or horizontal pipe running between 150 to 250 feet.

How deep should a well be for drinking water?

For drinking water wells it’s best to be at least 100 feet deep so that surface contaminants cannot enter the well. The average well depth for private homes is between 100 to 800 feet [2]. You may need a deeper or shallower well if your area has different geology than another region of the country.

What size is well casing?

Residential wells commonly have 4,5,6 inch casings. Older wells or agricultural wells tend to use larger casings, 8,10,12 inch (or bigger diameters) depending on the amount of water needed for pumping. Measure the outside diameter of the well casing.

Can you use PEX in a well?

The material is more durable under temperature extremes, chemical attack, and better resists expansion and contraction deformation, making PEX an excellent material for hot water and other applications.

Is well water better than city water?

Well water typically tastes better due to the lack of added chemicals. Public water is treated with chlorine, fluoride, and other harsh and dangerous chemicals. Well water travels straight up from the ground—you get all the health benefits of clean water with none of the harsh chemical additives.

Can a well last 100 years?

While people might say well’s life expectancy should be between 25 and 100 years, there’s no way to give an exact answer. However, we can calculate a reliable estimate of your well’s life expectancy if we know more about the type of well and conditions where the well might be located.

What happens to an unused well?

Wells that are no longer used may be buried or forgotten. Often they have not been sealed properly. Sealing is the process of clearing an unused well of debris and filling the well with a special material called grout. The sealing must be done by a licensed contractor.

Can I fill a 5000 gallon pool with my well?

Several factors go into whether or not your well has the capacity of handing filling a swimming pool. It’s estimated at 540 gallons per hour, it will take about nine hours to fill a 5,000-gallon pool with a 1/2-inch hose. Most larger, in-ground pools are around 18,000-20,000 gallons.

How long can you run hose on well?

Q. How many hours does a well pump run a day? Answer: On average, it can run up to 2 and a half hours.

How long should I let my well pump run?

So a minute on and a minute off has always been the minimum rule of thumb. Two minutes on and two minutes off is just that much better for the motor. With the old conventional pressure tank method, the pressure tank fills at the rate the pump can produce, less the amount of water being used at the time.

Does rain fill your well?

It’s a common misconception that rain has a direct impact on the amount of water in residential wells. Over 95% of rainfall doesn’t go directly into your well or even stay on your property; it runs off into creeks, streams, and rivers, some of which become part of the area’s surface water supplies, or “reservoirs”.

Does well water ever run out?

When a well “runs dry” it doesn’t mean that the well will never produce water again. Aquifers can recharge through a combination of more precipitation and less pumps pulling water out of that aquifer. Sometimes wells can run dry permanently, but that is quite uncommon.

Can you use too much well water?

The negative effects of over pumping are cumulative and lasting. When you over pump an aquifer the result can be the spreading of contamination or even land subsidence.
