Over time, the borehole is bound to experience various issues, which, often starting from a minor breakdown, can disrupt access to clean water.
Understanding these common problems is critical to maintaining an efficient borehole system. This article highlights the popular borehole issues and offers practical solutions to keep your water supply running smoothly and reliably.
Let’s get to it.
1. Common borehole problems
Your borehole may encounter different faults, but we will start with the most common ones you are likely to experience. Here are some of the common problems you may encounter with the use of your borehole;
1.1 Low water yield
A major problem with boreholes is their failure to produce adequate water, particularly during dry seasons. If you solely depend on your borehole system, this will undoubtedly significantly impact your home.
This problem is often caused by over-extraction, which may then result in low ground. This means that the groundwater is being used at a rate faster than it replenishes itself.
The first automatic thing to do is to reduce water consumption and save the water you have till you find a lasting solution.
To solve low water yield, you can either deepen the borehole’s reach or build a new water source. In this case, a professional is best to guide you on improving the depth of your borehole or finding a new water source.
1.2 Contamination
You may not be aware, but your borehole can become contaminated. If your borehole is located in an urban center, environmental activities like industrial waste, farmland chemicals, and several others can contaminate your water sources. Poor construction is also a possible cause of borehole contamination.
So, if you notice an unusual smell, color, or taste, you should give it immediate attention. Contaminated water poses health risks to you and your household.
The great thing is that contaminated boreholes can be treated. Chlorination, UV disinfection, and reverse osmosis are effective water treatment options to consider. Ensure you receive guidance on this treatment.
1.3 Pump failure
Another common problem you may encounter is pump breakdown. Iron oxidation and iron bacteria can significantly affect your borehole’s pumps. When iron contaminants accumulate in the pump, it begin to clog and corrode the pump’s parts.
One way to deal with it is to clean the pump system to get rid of iron bacteria. Use clean water to flush out any buildup of iron deposits.
You can also prevent pump failure by regularly checking and proper maintenance. If you notice red-tinted threads in your pump, it may indicate iron buildup. You should pay attention to it.
2. What are the causes of borehole failure in Nigeria?
Why do boreholes even fail? Ideally, boreholes are constructed to last for an extended period. However, certain irregularities can cause boreholes to fail or perform less optimally. Borehole failures often stem from specific causes, which include the following;
2.1 Poor siting
A lot of hydrogeological assessment goes into choosing the right location to site the borehole. This often includes studying the geology, the depth of the water table, the land topography, and the distance from contaminants.
If this process is not done properly, your borehole may be contaminated or have a low water yield.
2.2 Poor construction and installation
If the borehole is sited in an appropriate location but inadequately constructed or installed, it is still at risk of failure.
Poor construction or installation may result in errors such as improper casing or other hydraulic faults. If the casing is not installed properly, surface contaminants seep into the water supply, leading to a contaminated supply.
It is important that you get tested and reliable professionals to take care of your drilling process.
2.3 Environmental factors and seasonal changes
Changes in the climate in your area may cause you to experience some inconvenience with your borehole.
During the dry season, your borehole may experience a drop in groundwater levels, which may affect the water yield. Urbanization can also cause groundwater levels to drop, leading to reduced water yield.
Changes caused by environmental factors are gradual and may eventually become permanent if a sustainable approach to groundwater use is not taken.
2.4 Poor maintenance
Generally, nothing poorly maintained ends well. Your borehole will quickly develop faults if it is not properly maintained. Avod over pumping, carry out regular routine checks and fix faults promptly.
3. How to deal with common borehole problems
3.1 Regular maintenance
Implementing a maintenance schedule for routine inspections, cleaning, and repairs can significantly extend the lifespan of boreholes. Engaging local technicians for regular checks can help identify and rectify issues before they escalate.
3.2 Conduct hydrogeological assessments
Conducting thorough geological surveys before drilling can help identify the best locations and depths for optimal water yield. Understanding the local geology is crucial for successful borehole placement.
3.3 Use proper drilling techniques
Ensure you engage reliable and experienced borehole drillers. Trusted and experienced drillers are more likely to prioritize best practices to ensure that boreholes are drilled correctly, reducing the risk of errors and failures.
3.4 Monitor water levels and usage
Take note of the level of water your borehole pumps out and consume water responsibly. Get professional help if you notice a reduction in the water yield, as this may be a sign of reduced groundwater.
4. Final words
Your borehole is expected to function optimally for a long time, but sometimes, common faults may affect its effectiveness. By understanding these common problems and implementing these proactive solutions, you can ensure a sustainable supply of clean water in your home.
