Boreholes

Boreholes are a narrow shafts bored in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes, including the extraction of water, other liquids or gases… A well-maintained borehole is also a cost-effective, self-sufficient asset. Although initial costs of drilling and equipping may be high, there are long-term financial benefits to groundwater, particularly the fact that borehole water costs significantly less than municipal water. “A borehole is an asset that should last you at least 10 to 15 years at very little ongoing cost, provided you buy correctly at the start!

Borehole Water comes from rain and rivers leaks through layers of rock from underground areas. Water layers of rock or clay separate and restrict underground water bodies at different depths, in different areas. These areas are called aquifers. On the whole borehole water is safe to drink; however, it could possibly contain dissolved minerals or contamination. If there are concerns over the waters fitness use we can have the water tested by an accredited laboratory that will give a detailed report of the water.

As a general rule of thumb, a properly installed and sized boreholes should last 8-10 years. If you have only just installed a borehole, you’re likely to see years of service from your current equipment. Depth of about 220 m is suggested for boreholes to be drilled in the area. Generally, variation in the depth extent of pollution in the regions of investigation could be as a result of variation in the level of abstraction of water from boreholes in the regions.

Can borehole water run out? Each borehole will have its own characteristics. Boreholes that are only metres apart can have completely different water levels and delivery capabilities. But, if you and your neighbour are pumping from the same aquifer, over pumping your hole could cause their hole to dry up.
