How Do I Determine the Depth of My Well and Choose the Right Pump?

If you own a house with a well, you already know how important it is to have a reliable water supply. However, you should be aware that calculating the depth of your well and selecting the appropriate pump is critical.

How Do I Determine the Depth of My Well and Choose the Right Pump

In this article, we’ll look at the steps you can take to ensure that your well is working to its full potential. In addition, we’ll look at the best water possible.

To quickly recap, these are the topics we have discussed.

How to Determine the Depth of a Well

Checking the well records or consulting an expert are viable options for determining the depth of your well. When drilling a well, drillers are required by law in several states to record the depth of the well.

These records are frequently kept on file at the state or municipal water department. If you do not have access to these data, you can contact a local water specialist or the person who drilled the well for assistance.

If you prefer, you can determine the depth on your own using a rope or a tape measure. Because it can be challenging to gauge the depth of the water in the well using this method.

A well depth gauge or an electronic depth finder will provide a much more precise measurement. The depth of the well is determined by measuring the distance from the surface to the water level using a sensor in these instruments.

You can get them at a hardware store or on the internet, and they are generally simple to use. To obtain an accurate depth reading, insert the sensor into the well and follow the manufacturer’s instructions.

Factors to Consider When Choosing a Pump

Before purchasing a pump for your well, several factors must be considered. The depth of the well and the amount of lift required are two of the most critical factors. This will help you determine the size of the pump as well as the capacity required.

For example, a higher horsepower pump will be required to bring the water to the surface if you have a deep well. If you have a shallow well, on the other hand, you can get away with a less powerful pump.

You should think about the type of well you have. There are many wells, each requiring a different type of pump. A submersible pump, for example, is often the most appropriate option for a deep well that has been drilled. However, a surface pump is usually better suited to a shallow well that has been excavated.

Another critical consideration is the amount of water required and its quality. If you have a large family or regularly use a lot of water, you’ll want a pump with a higher flow rate. It would be beneficial if you also considered the water quality provided by your well.

Assume the water is difficult to pump or contains significant sediment. In that case, you may want a pump with a specialized filter and other features to ensure the water is clean and safe for human consumption.

Another essential factor to consider is the pump’s size and capacity. You must select a pump that can meet your water requirements while being manageable enough that it constantly loses energy.

Last but not least, consider the power source at your disposal. If you have access to electricity, you can choose from a wide range of pumps. If you don’t have electricity or want to be more conscious of your actions’ impact on the environment, consider getting a solar pump or a pump powered by a generator.

Types of Pumps to Consider

You will have several options when deciding on the right pump for your well. The following is a brief description of each type:

Surface pumps: These pumps are typically located near the wellhead on the surface. They pump water from a shallow well or cistern and can be powered by electricity or a gasoline engine.

These pumps are intended to be installed within the well, usually at the bottom. They are known as submersible pumps. They are powered by electricity and are submerged beneath the water’s surface. Submersible pumps are commonly used in deep wells because they can draw water up from deep depths.

Hand pumps are manually operated pumps commonly used in shallow wells or cisterns. These pumps are commonly found in older homes. They are an excellent option for locations without power or as a backup in an emergency.

Solar pumps: Because solar panels power them, they are an excellent choice for off-grid living or lowering your carbon footprint. Solar panels are a type of renewable energy. Solar pumps are frequently used to draw water from shallow wells, cisterns, or other storage tanks.

When shopping for a pump, you must consider the depth of your well, the amount and quality of water you require, and the power supply available to you.

How to Select the Right Pump

Before selecting the right pump for your well, you must determine the required flow rate and pressure. This will help you determine the size of the pump as well as the capacity required.

Before making a decision, consider the type of well you have and the quality of the water it provides. One type of pump may be more appropriate than another, depending on the type of well and the water quality.

You can begin researching and comparing various pump types and brands when you’ve determined your needs. When comparing pumps, it is critical to consider many factors, including flow rate, pressure, size, capacity, and power source.

Reading reviews and seeking advice from friends or experts with prior experience with well pumps may help you make a purchasing decision.

Finally, when selecting a pump, it is always a wise idea to seek the advice of an expert or a dealer with extensive knowledge of the field. They can help you choose the most appropriate pump for your specific needs and answer any questions. They can also provide helpful information on installation and maintenance.

How do you calculate what size well pump I need?

To determine the size of the well pump required, first estimate your well’s flow rate. This is the amount of water a well can produce in a given time. You’ll also need to determine your well’s pumping and static water levels.

The static water level is the depth of water in the well when the pump is turned off. On the other hand, the pumping level is the water in the well when the pump is turned on.

Once you have all of this information, you can use the following formula to determine the size of the pump you need:

The flow rate in gallons per minute is calculated as follows: (Pumping level minus Static water level) / (Drawdown time multiplied by Recovery rate).

When the pump is turned on, the drawdown time is the amount of time that passes before the water level in the well begins to fall. The recovery rate is when the water level in the well returns to normal after the pump has been turned off.

After determining the flow rate, consult a pump curve chart to determine the pump capacity that will be required. The pump curve chart will show the relationship between the flow rate and the total dynamic head, which measures the flow resistance in the well system.

This resistance could indicate how difficult it is to move fluid through the system. You must select a pump that can provide the required flow rate while maintaining your desired total dynamic head.

It is critical to remember that the preceding is only a high-level overview of choosing the appropriate size well pump. There are numerous other factors to consider, such as the type of well, water quality, and the power supply’s availability.

When in need of guidance and assistance, it is recommended that one seek the advice and assistance of an experienced or professional dealer.


Finally, determining the depth of your well and selecting the appropriate pump are two of the most important things you can do to ensure that your well is operating efficiently and reliably, providing you with clean, risk-free water.

You can determine the depth of your well by checking the well records, measuring with a rope or tape measure, or using a well depth gauge or electronic depth finder. Other methods include using a depth gauge or an electronic depth finder.

When choosing a pump, consider the depth of the well, the type of well, the amount and quality of water required, the size and capacity of the pump, and the available power source. Pumps come in various styles, including solar pumps, hand pumps, surface pumps, and submersible pumps.

To select the right pump, determine the required flow rate and pressure. Consider the type of well and the quality of the water. Conduct research on and evaluate various pump models and brands, and seek advice from a qualified individual or an experienced dealer.

If you follow these steps, you can be confident that you are choosing the right pump for your well and establishing a reliable water supply for your home.
