Four generations of experience installing, maintaining and
repairing wells throughout Utah and Wyoming.

In part one of this two-part blog series, we went over some of the basics on your water well casing. One of the single most important components in a water well, the casing helps not only support the well itself, but also prevent contaminants from making their way into your drinking supply.

At Mike Zimmerman Well Service LLC, we’re happy to explain any details of water well casings to you during well drilling and installation, well rehabilitation or any of the other water well services we provide. It’s important to protect well casings and keep an eye out for any potential signs of damage or resulting leaks, which can lead to significant issues if they aren’t prevented – today’s part two of our series will go over how to understand and spot these signs, plus how damaged well casing will be repaired.

Causes of Water Well Casing Leaks

There are several potential causes of cracks or leaks in water well casings:

  • Time: Over a long period of time, whether due to ground shifting, a natural disaster like an earthquake or nearby blasts from a construction site, cracks may develop in water well casing.
  • Object damage: In other cases, stones or other objects that press up against the casing may also damage it, leading to defective seams that will allow groundwater and contaminants into your water supply.
  • Lightning strike: Rarer, but can cause well casing damage.
  • Corrosion: For those with steel casing installed, corrosion over time may lead to wear-down and even damage of the casing itself.

Be sure to inspect casing regularly, especially the section that sticks up above the ground – this part is exposed to the elements and has especially high cracking risks.

Signs to Look For

There are a few common signs of potential casing leaks to look out for:

  • Sand, dirt, sediment or other contaminants in your water supply with no other explanation.
  • A gradual decrease in water flow over time, also with no other explanation.
  • Water filters suddenly need replacement much more often than previously.

Repair Process

If you notice any of the above signs, call our water well professionals right away. We’ll perform a process where we lower a camera into the well to thoroughly inspect the casing and other areas. If we determine there is indeed a casing leak or similar issue in your well, how we proceed will depend on whether it’s a single minor leak or multiple major ones – the former situation generally allows a simple repair sleeve or well liner for repair, but the latter may require more significant repairs.
