Does Your Water Well Pump Sand? These Could Be the Reasons Why

In this period where modern technology has dominated the world, many things have changed, including the way people live. But did you know that there are 42 million Americans who still use household wells for their water supply? What’s more surprising is that a large cluster of these families lives in urban areas.

Water wells are substantial in our society. They are a source of reliable and ample water supply for countless households, irrigations, and industries. In places like deserts where water is limited, people use water wells to get underground water to survive and live. However, serious problems might occur if your well starts pumping sand, dirt, or silt.

Some of these issues include:

  • Loss of water pressure
  • Fixtures damage
  • Clogged pipes
  • Destruction of your home appliances

When it comes to sand management, you might need the assistance of well specialists. If you’re looking for reliable well contractors, you might want to check out Enercorp.

So, what could be the reasons that sand is getting into your well?

Why Sand Gets into a Well

1. You have an extra-large well pump.

If your pump is too huge, it will shoot the water so high due to extreme force, pulling sand from the surrounding aquifer. As a result, there will be a fast deterioration in the pump’s valves, causing a sand build-up at the bottom of the well. That’s when sand begins coming out of your water lines.

2. Degraded well screen or well casing

During your well drilling, your well contractors lined it with iron, steel, or PVC plastic called casing. Then they will install the casing in the well shaft. In the casing, there are grooves, allowing water to penetrate the well from the surrounding groundwater and, at the same time, to keep out grit and sand. This is called the well screen.

Your submersible pump inside the casing is placed under the water. But, a good screen can corrode or break down over time, leading to sand and silt getting in the well, which is then pumped into your water system.

3. Your well pump is too low or improperly positioned.

If you observe that your well is suddenly pumping sand or sediment, this could be due to the low position of the pump near the bottom of your well since most water wells utilize submersible pumps in a casing under the water.

Usually, the pump is at a minimum of 10-20 feet higher than the case of the well. But if the pump is too low near the well’s base, grit, sand, and sediment can be drawn in. In addition, if your well is old, the well shaft can fill up with fine silt and sand, making the pump start drawing in sand from this build-up.

How to Clean Sand Out of the Water Well?

If you observe that your water well begins to pump sediment or sand, contact your local well professionals or specialists right away. They are your go-to people who can determine the main problem and discover ways to fix it. 

Also, if you’re wondering whether a DIY repair works, this might be a bad idea considering that there are situations when these well specialists have to pull up the pump 10 to 20 feet to get rid of sand uptake. They are highly trained with modern sand management technology and specialized equipment and devices, like a camera, to examine your well screen if it needs repair. Also, they have enough experience in the industry and have probably seen the same cases as yours. 

In some severe cases, they might recommend you to get a brand-new casing. Other possible options they can recommend include:

  • Centrifugal sand separator
  • Filter screen with flush valve
