A well can run dry due to changes in the surrounding area. They depend on naturally occurring water sources and can typically last between 30-50 years before running dry.
Where Does Well Water Come From?
Typically, almost all well water comes from groundwater, as stated above. Groundwater is a collection of precipitation and surface water that seeps through both rock and soil to get to the underground aquifer.
It is quite possible for several wells to share a single aquifer. This happens because of precipitation variations throughout the seasons and overpumping, which can cause aquifers to dry out.
Your location ultimately decides exactly where the well water comes from. Factors like how the well was drilled and local weather patterns can play a role. The water cycle, however, will always remain important when it comes to private wells.
What Causes A Well To Run Out Of Water?
There are several reasons why a well may run dry. These issues can be the result of natural factors or simply the result of well mismanagement. Let’s take a look at some of the most common reasons why wells run out of water below.
Low Water Levels
A sudden decline in groundwater in certain areas can cause a well to run dry. This can happen due to an extended drought or because additional wells have been dug in the area.
When more wells are installed, water usage in your area will increase significantly. This will mean there is less water available for your well.
Less Precipitation
Precipitation is undoubtedly the most common source of well water today. Rainfall and other precipitation will seep into the ground, collecting in underground cavities known as aquifers.
Wells are drilled into the ground to specifically access these natural reservoirs. Wells can run dry in the event there is less precipitation than usual.
Buildup Of Sediment
Loose sediments and minerals can accumulate in the well as time goes on. A large accumulation of sediment can cause a loss of water flow.
Unfortunately, this can be a natural process impacting most wells. However, if you maintain your well properly, you can prevent this issue.
Soil Type
It is possible for your well to struggle replenishing itself due to the area’s soil type. For example, a well that’s been dug in rocky soil will take longer to refill than one dug in sandy soil.
Increased Water Consumption
Wells typically take a long time to refill, regardless of outside factors.
It goes without saying that if your water usage is quite high, your household may not be giving the well enough time to refill.
Conclusion
As mentioned above, most wells can last between 30-50 years before drying up. Other factors, such as lack of maintenance and quality of construction, can impact this expected timeline.
