South Africa has become very aware of the need for freshwater surface water over the last few years. With water shortages, failing infrastructure that loses water, droughts and population growth, we all realise that we need additional water to satisfy the high demand for it.
Enter the increased need and interest in borehole water.
Even as we enter the rainy season, water levels are often not raised significantly enough in our dams to ensure that there is enough to supply for the increase in demand. Therefore, the interest in finding alternative water sources has surged, and is not only interesting, but essential to the survival of domestic, industrial and commercial industries.
With this in mind, we look at the Pros and Cons of borehole water.
What is borehole water?
Borehole water is a small, open, narrow shaft that is drilled into the ground, horizontally or vertically, to access water. It is how you get access to pure underground water that is naturally flowing. When it rains, the rainwater seeps through the layers of soil and rock and is known as groundwater. This can also be contributed to by streams, rivers and dams.
Advantages of boreholes and borehole water
Having access to a borehole or borehole water is an affordable option and is arguably the cheapest way to deliver water to homes and for crops. If there is a good flow of groundwater, once a borehole has been dug, it can be used for all water needs.
In normal conditions groundwater that is tapped, is safe for limited agricultural needs as well as for domestic use, but will most likely need some form of purification. It is always advisable to have this water tested before use.
Borehole water is suitable for domestic non-potable uses such as toilet flushing, car and clothes washing as well as watering of grass, gardens and even crops. Borehole water is a surefire way of decreasing your municipal water usage from a tap – limiting that use to cooking, drinking and bathing.
Disadvantages of boreholes and borehole water
A significant factor to consider is that the immediate environment where the borehole is dug can impact the water with contaminants. If there is a high level of contamination in the area near the borehole water, it is likely that the water will be affected.
A disadvantage to using borehole water is that it can’t be used for every form of consumption, without purification treatment, such as cooking, watering edible vegetables and drinking. This cannot be done straight from the source due to the possibility of contaminants. As a result, the water needs to be tested and a water purification system installed which will increase the cost.
One other problem is the environmental impact experienced in the long run should the number of boreholes increase in an area and impact the groundwater levels.
Can borehole water be purified?
It is possible to purify borehole water by putting the water through a testing process and installing the correct purification system. This will then make the borehole water suitable for drinking as well as irrigation.
