Wells are a reliable way of ensuring adequate water supply, especially in areas that experience little rainfall. By drilling deep into the earth, you can take advantage of a natural water table whose supply of water rarely runs. Thereafter, you can pump, treat and purify the water to make it safe for washing, cooking, drinking and other activities. The only challenge with wells is that they might start to perform poorly after some time. Poor well performance can affect he reliability of water supply and heighten the pumping costs incurred to draw that water from the well. Here is a discussion that will take you through poor well performance and remediation techniques:
What Causes Poor Well Performance?
- Declining water table- a decline in the water table is a notorious cause of poor well performance. The water table can decline because of regional geographical influences such as shrinking rivers, reduced amounts of rainfall and accumulation of fine soil particles within the well. This means that the original well you had drilled will receive lesser amounts of water from the water table, leading to poor well performance.
- Structural failure of the well-structural failure of a well basically refers to an interference with the initial configuration of the hole you had drilled. In most cases, it results from natural causes such as soil subsidence, landslides, tectonic plate movements and collapsing of the casing in the well.
- Clay and Silt Infiltration-when you drill a well, there is an alteration of the surrounding soil] structure. Fine particles and silt, which cannot be kept put by the well's filter pack, can find their way into the hole and impair the efficiency of the well.
What Can You Do to Remedy Well Failure?
Thankfully, poor well performance can be remedied to keep your water supply steady and reliable. Some of the implementable remedy measures include:
- Deepening- deepening a well is a proven technique used to eliminate some of the challenges experienced poor well performance. You can dig deeper into the ground to reach a new water table or aquifer with better water supply. To add on that, you can deepen the well so that the entry point of the water is in a place where there are little clay and silt infiltration.
- Hydro-fracture-this is a technique employing both pressure and drilling to improve the structure of the well and its water supply.
It is important to contract professional basement drilling services if you want to get the most of a well. Some of these problems result from poor planning and initial construction.Share
