Irrigation wellYou may have wanted to give up on irrigation farming due to the unavailability of constant fresh water in your area. If that is your worry, your troubles are about to end. Let us introduce you to irrigation wells, an incredible solution to all your irrigation water issues.

If you have never heard of them or have, but you are not well versed on the topic, do not worry. Below is everything you need to know about irrigation wells.

What is an irrigation well?

This is a drilled well that is often connected to sprinkler or drip line systems. The aim of doing so is to supply water to plants (irrigating land).

Can you have irrigation with a well?

Yes, one can irrigate their land with a well. However, there are quite a number of things that need to be looked at before your well is up and running. Some of these things include; the well’s location, the size of the aquifer, and the depth of the well. These things can be a bit confusing. That is why it is important to talk to experts before embarking on the irrigation well drilling process.

Should I install a well for irrigation?

Why not? Installing a well for irrigation keeps your lawn looking lovely even at the height of summer.

Besides aesthetics, there are numerous other advantages of irrigation wells. Here are some examples;

  • Reduces farming expenses

Farmers with irrigation wells do not have to pay for water bills to municipalities. This is because they have their own water source.

  • Quick and Easy Way to Irrigate

Irrigating your land with your hands is a tedious and time-consuming task. With an irrigation well, the opposite is true. Having one makes watering your plants a quick and straightforward exercise.

How does an irrigation well work?

A typical irrigation well has a casing (pipe), well screen, and a pump. The casing protects the well from contamination and keeps the mouth open. It also protects submersible pumps and wiring systems.

After fitting a casing pipe, the well expert installs a well screen. Its function is to prevent loose debris in the aquifer from entering the well.

For the water to reach the surface, a pump must be put in place. A well water pump creates the suction needed to pull water from the well through the pipes to the surface.

Once on the surface, the water can be distributed to plants through the sprinklers or drip lines.


Many lawn owners prefer watering their lush gardens using sprinkler systems. In this system, water flows through irrigation pipes at high pressure. Once it reaches the sprinkler heads, water is broken down into tiny droplets. It is these droplets that fall on lawns as rain.

However, one can also go with drip irrigation, where the well’s main pipe is connected to drip lines. The line has emitters that release drops of water at the base of the plant.

All in all, each method has its benefits and drawbacks, and it all boils down to preference.

How deep should an irrigation well be?

Most irrigation wells are often 50 to 1000 feet deep. This depth varies due to a number of factors. One of these factors is the area and location of the aquifer. In Florida, for instance, irrigation wells can go as deep as 1000 feet as Kitchen states.

The type of well one wants also determines how deep it needs to be dug. Shallow wells, for example, are less than 100 feet deep. On the other hand, deep wells can go as deep as 2000 feet depending on water table depth.

How long do irrigation wells last?

Typically, the life expectancy of a domestic well is between 25 to 100 years. When it comes to an irrigation well, things are a bit different.

Irrigation wells may not live as long as domestic ones. One of the reasons for this is that, in irrigation wells, a lot of water needs to be drawn quickly out of the aquifer. It is this heavy demand and usage of water that shortens its lifespan.

Another reason is the popularity of sprinkler watering systems. As we stated earlier, many people are drawn towards using sprinklers. The issue here is that sprinklers need lots of water to properly irrigate plants, as most of it is often wasted. As we explained in the first point, heavy water needs to shorten the well’s lifespan.

Overall, irrigation wells will serve you for a good amount of time as long as you maintain them properly. Putting in place measures to conserve the water also goes a long way.

How do you calculate irrigation flow rate?

Irrigation flow rate is the amount of water emitted from an irrigation system for a specific amount of time. It is usually denoted as GPM (gallons per minute). Some sources may use hours instead of minutes, thus denoting flow rate as GPH (gallons per hour). All in all, the principle is the same.

Here is a simple procedure to help you calculate the flow rate of an irrigation system;


  • A five-gallon bucket of water (empty)
  • Stopwatch

Procedure (applicable to small irrigation systems)

  1. Disconnect the main pipe from the pump.
  2. Start the stopwatch at the same time as you begin collecting the now running water to the bucket
  3. Stop the stopwatch immediately after the bucket fills up.
  4. Divide 5 gallons or the volume of water in the container with the time it took to fill up.

To know how much water your plants are receiving;

  1. Count the number of drip irrigation nozzles supplied by the pipe you drew water from
  2. Divide that figure by the value you got in step 4.

Alternatively, you can use a flow rate calculator. This computerized program will quickly do all the necessary calculations for you.


An irrigation well is crucial for sustaining your lawn and crops. It is cost-effective and guarantees a continuous supply of water. Of course, we cannot forget that it eases and speeds up the irrigation process. Now, if you do not have an irrigation well and would like one, kindly call us and schedule a meeting.
