If you’re planning to dig a water well in your home, you may have questions regarding ground penetration and how deep a well should be. In general, many wells have a diameter of six inches and a depth of 300ft, but this depends on several factors, which we discuss below:
Water quality
The local government sets specific rules on the minimum depths for wells. This is because water at the top is susceptible to contamination from pollutants in the soil. Generally, the deeper the well, the better the quality of the water. Therefore, it’s good to dig a few feet more than the minimum depth set by the local government.
Rock formation
If you’re in a landscape with extremely underground rocky formations, the depth of the well can reach a few thousand feet. You need to work with a contractor who knows how to drill wells in rocky areas.
Level of the water table
When drilling a well, the contractor has to know the water table level in your area during different seasons. The depth of your well should be more than the water table level when it’s the driest season. In most cases, the contractor will use the average statistical data over a few years to know the ideal depth. Therefore, ensure the contractor that you’re working with is experienced enough to know these vital details.
Surface contamination
We’ve already stated that the deeper the well, the better the quality of water you get. However, if the well is too deep, it means water has to pass through soil and rocks to reach the surface, and this can increase the chances of contaminants finding their way into the water stream. Also, minerals can easily leach into the water, which will necessitate water softening. The point here is that your water well shouldn’t be too shallow or too deep.
Longevity
Deeper wells tend to last for many years as they have low silting at the bottom and low draw rates. On the other hand, shallow wells experiences high silting, which pushes maintenance costs up. That’s why many people opt for deeper wells.
Building codes and regulations
Your local government sets regulations regarding the depth of a well, and it’s important to follow them to avoid getting into legal battles with the authorities.
The building codes and regulations cover sealing well-cap reinforcements and grouting requirements. In general, these regulations require the casing to reach the bedrock.
Conclusion
If you’re planning on getting a well for your residential property, you need to work with a reputable contractor conversant with all the crucial details regarding the depth of wells in your area. In addition, they should give you an idea of the cost involved from the start so that you can arrange your finances.
