Is my well shallow or deep? 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). Click to see full answer.
Do you need a deep well or a shallow well?
While deep wells are more protected against drought and contaminants, they also carry a higher price tag. You may have excellent resources for many shallow wells on your property that would cost you less to have placed. Your best option is to contact a professional like Empire Pump Corporation.

How can I tell how deep my well is?
If you cannot see the top of water in your well then you can tie a fishing float or "bobber" to your string and lower it carefully into the well until it stops dropping. Mark the string at ground level. Measure that string length - that's the depth from the ground surface to the top of your well water.
What constitutes 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 is a well. A well is considered to be shallow if it is less than 50 feet deep. The source of a well is an aquifer.
What is considered a shallow well pump?
Shallow well pumps are found in applications where the well is less than 25' deep and operate as above-ground well pumps. This style of pump is not submersible and is placed outside the well in a well housing. A feature you should look for is overload protection, which prevents motor burnout.
How do I know what type of well I have?
You may be able to determine the type of well you have by looking at the outer casing and cover of the well. According to the United States Environmental Protection Agency (EPA), there are three basic types of private drinking wells dug, drilled, and driven .
Do I have a shallow well?
The diameter of your well casing determines what type of well pump you need. If you do not have a well casing, you have a shallow well. Some well casings are 2” and require special accessories with a convertible jet well pump.
How deep is the average well?
100 to 800 feetMost 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.
How deep should a well be for drinking water?
100 feet deepFor 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.
How deep is a shallow well pump?

Can you drink from a shallow well?
Your well water may NOT be safe to drink. water if the well casing is damaged or if you have a dug or shallow well. get into Maine wells from nature. They're in the rocks and can dissolve in water.
What are the 3 types of wells?
There are three types of private drinking water wells.Dug/Bored wells are holes in the ground dug by shovel or backhoe. ... Driven wells are constructed by driving pipe into the ground. ... Drilled wells are constructed by percussion or rotary-drilling machines.
How do well drillers know where to drill?
Geophysics methods can be used to identify the presence of water at depth. They are based on the changes in electric conductivity caused by the water. Finally bore holes can be drilled to assess the geological sequence of the strata and to identify layers potentially able to host an aquifer.
Does a well replenish itself?
How does a well replenish itself? A well replenishes itself by drawing water from the underground aquifer. Other sources with which a well may replenish itself include rain, lake or river water seeps into the ground to refill the aquifer from which the well is drawing water, and snowmelt.
Why do you not drill shallow wells?
Most do not drill larger diameter shallow wells due to cost. The advantage to a larger diameter may be flow or to enable the use of a submersible pump. The advantage of drilling a small diameter well point is cost. Another is the fact that you may drill multiple wells and tie them into an above ground centrifugal-jet, end-suction type pump.
Is a PVC well a shallow well?
Sometimes it is with the size casing. 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.
How to determine how much water is stored in a well?
Once a well is drilled, the total depth, depth to the top of the ground water table (static level) and diameter of the well determine how much water will be stored within the well cavity. The larger the well diameter the more water will be stored for a given well depth and water table elevation. To find the “thickness” of the water stored in ...
How much casing do I need for a well?
Most states require a minimum of 20 feet of casing and often require the casing reach bedrock.
What is grouting in a well?
Proper grouting (sealing) around the outside of the well casing in combination with a vermin-proof well cap , prevents surface water and bacteria from using the well hole itself as a pathway directly to the water table. Well depth plays a role in pump placement. Pumps should never be set directly at the bottom of a well.
How far up should a well pump be from the bottom?
Well depth plays a role in pump placement. 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.
How far up should I put a well pump?
It is usually best to place the pump 10 to 20 feet up from the bottom of the well. In low-yield wells that recharge slowly, placing the pump below the recharge zone may create cascading water situations that lead to additional sediment build up in the well cavity.
Why does the water table fluctuate?
During the year, the water table will fluctuate up and down in the well in response to seasonal precipitation in the area and local ground water use. The well must therefore be drilled deeper than the lowest expected elevation of the water table.
Can you determine the depth of a well before drilling?
Most of the time, however, the depth needed to find the required well yield cannot be determined accurately prior to drilling. A well is an engineered hole in the ground via which ground water can be brought to the surface. Drilling machines can drill to great depths. Deeper wells usually cost more than a shallow well to construct in the short-run.
How deep can a well be dug?
As you can tell by the names, deep and shallow well s are dug to different depths underground. The well drilling contractor will know the exact depth your well should be based on the terrain and water table. Shallow wells are generally for water less than 25 feet from the surface, and deep wells can go down hundreds of feet.
Why do wells use pumps?
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. Pumps for deep wells are submersible and buried deep underground with the controls are above ground. The water from a shallow well is drawn from a higher level than ...
How much water can a pump move?
Pumps come in 1/2-, 3/4-, and 1-horsepower models. Most 1/2-horsepower pumps can move about 7 to 9 gallons of water per hour, which is suitable for most homes.
What is A&T well pump?
A&T Well and Pump specializes in the installation, repair, and replacement of well pumps and wells. We know what kind of well you need and the appropriate well pump for your individual situation.

We compare two pumps in each category, deep and shallow. When you hire A&T to work with your well, we will make a recommendation that takes into consideration the factors that make up your specific environment and use. In the meantime, here is some basic comparison information we hope you find helpful in gaining general knowledge about well pumps.
What does overload relay do in a well pump?
Most shallow well pumps have an overload relay that protects the pump by shutting it off before it overheats, damaging the motor. For instance, without overload protection, should a leak occur in the supply tank that prevents the pump pressure switch from reaching the cutoff of 50 psi, the pump could continually work to reach that threshold and burn out the motor. If you have overload protection, it senses that the motor is overloaded and shuts off the pump.

Do well pumps work with air to water tanks?
The tank functions as the home’s pressurized water supply, so the pump doesn’t turn on every time someone opens a faucet. Shallow well pumps work with either pre-charged storage tanks or air-to-water tanks. A pre-charged storage tank has a bladder inside the tank.
What is the definition of depth in a well?
Definition of well depth: the distance from the ground surface to the bottom of the bore hole. Definition of water level: the height to which water rises in a water well when the well is at rest and fully recovered after recent use.
Why do we need to know the depth of the water level in a well?
As we explain below, there are reasons we want to know the depth from ground to the top of the water level in the well: to calculate the well's static head or volume.
What is drawdown depth?
Definition of drawdown depth: the depth to which the pump lowers water in the well when the pump is running. In a well whose flow rate is greater than the pump's rate of removing water from the well, the drawdown depth will be somewhere below the top of the static head and the water intake at the pump or foot valve.
What does it mean when a well is fully recovered?
That means that no water has been drawn from the well (the pump is off or no water is being run at the building (s) served by the well for an interval long enough that the well has fully recovered.
What company does well depth measurement?
The Water Ace Pump Company [cited at REFERENCES] as well as other water equipment companies like Flotec® offer a simple well depth measurement procedure that works for drilled wells or hand dug wells. We have added some details.
How deep should a water ace be?
Water Ace explains how to select the depth to which your submersible pump or foot valve should be placed in a water well. Subtract five feet from the depth of your well. This number should not exceed the maximum rated depth for your pump. If it does, it will greatly hinder or prevent the proper operation of the pump.
How to get water to stop dropping in a well?
If you cannot see the top of water in your well then you can tie a fishing float or "bobber" to your string and lower it carefully into the well until it stops dropping . Mark the string at ground level. Measure that string length - that's the depth from the ground surface to the top of your well water.
Where Does Well Water Come From?
Nearly all private well water comes from the ground. As rain and snowmelt seep into the soil, it fills the spaces between rocks. Known as the saturation zone, or water table, it’s the primary source of water for most shallow wells. Deeper wells tap the plentiful underground aquifers beneath the water table.
How Does a Well Work?
A well is a hole in the ground dug deep enough to strike water. Lined with a well casing to prevent collapse, it’s equipped with an automatic well pump that draws water from the depths. To learn more about the inner-workings of well, read our post on how a well works.
How Deep Is an Average Well?
The average well depth is 100-500 feet, but depending on several factors from climate to geology, the depth ranges from as little as 20 feet to 1000 feet or more.
Types of Wells
There are few different types of residential well systems with the common one being a driven well:
How Much Does a Drilling a Well Cost?
Well drilling is an imperfect art. Companies charge by the linear foot, and the deeper the well, the more it costs. A dug well could run as little as $2000 — drilling deep can set you back $15000 or more plus the price of the casing and pump.
Do Deeper Wells Mean Better Water?
While there are exceptions to every rule, deeper wells generally offer better water quality and are less likely to run dry.
Should I Filter My Well Water?
Despite your best efforts, some wells won’t produce the premium water you hoped for no matter how deep they are.
How deep is a well?
This alone tells you that the well is probably around 100 feet or less , any deeper and you'd have to use a submersible pump. If there are two pipes going into the well, then you have a jet type pump, if there is only one pipe you have a suction pump which is less than 25 feet or so.
How to tell when a rope hits the water?
It's easy to tell when it hits the water, and you just let it settle slowly until you feel it hit the bottom. Pull the rope up and measure from the bottom until the rope is dry. I usually have 20 feet or more of water reserves, but I've not tested it this year. I need to.
We thought we should share our answer on our web site. Here it is
Myra’s Wells’ mission is to work in villages all over Burkina Faso. Usually, there will be at least 600-700 people in the village, and up to 2000 people might actually benefit from the wells. However, the depth of the wells varies according to the geology.
Prayer is needed. The north is where water is most needed, but there is a problem .
The worse problem now is the terrorist activity which prevents travel there. None of the drilling companies are willing to send their workers and equipment there. There are many people who have been displaced from there to nearer Ouagadougou – the latest estimates say it could be as high as 500,000.
