Why is it important to use a reputable borehole drilling company?
Unfortunately, there are unethical borehole drilling companies out there. Here are a couple of questions to ask any borehole company that you are considering working with. Their answers to these questions will help you determine how experienced they are at finding water and drilling.
Do they offer a comprehensive borehole water survey
A borehole water survey ensures that there is indeed water under your property. Without knowing if you have an aquifer and how deep it is you rely on the luck of the draw to find water. That could cost you thousands of Rands without any water to show for it and you ending up with a dry borehole you still need to pay for.
Do they use high precision air compressed drilling techniques?
To ensure a good supply of water you must be able to drill straight. Inferior quality equipment could drill skew shafts resulting in poor or no water supply. Moreover, to ensure the drilling company is legitimate, ask for their BWASA certificate and cross check with BWASA if its valid at the time. A skew borehole shaft goes against BWASA standards. Appointing the wrong drilling contractor could lead to a non-compliant borehole being drilled which will mean that you will not be able to get a valid Borehole Certificate (COC) for your borehole (after Borehole Yield test has been completed). The commercial banks and insurance companies require you produce a valid borehole COC to establish the value of the borehole.
Do they include 'developing’ the borehole (flushing the borehole with clean air & water after drilling)
Unless you want to drink mud, developing the borehole is essential. This process, which is conducted after water has been found, flushes the borehole clean and removes mud and other debris from the borehole. Make sure that the cost is included in your quote so that you have clear water
What type of borehole casing do they use and do they case the full length of the borehole?
Casing the full length of the borehole ensures it lasts a long time whereas not casing the borehole shaft could lead to the collapse of the borehole. Some contractors cut corners here to offer “cheap quotes”. Make sure you get quoted on class 9 uPVC casings which are belled & perforated to the correct depth and installed to the full length of the borehole. Your borehole should also be fitted with a gravel filter pack to ensure consistent water quality.
Do they offer a yield test service with a BWASA certificate?
Without knowing how much water the borehole produces we will not be able to recommend the right pump to produce optimal results. Over pumping the borehole could cause it to collapse and the motor to run dry and burn out. We therefore provide a comprehensive yield test, that takes 4.5 hours to complete, which is approved by the BWASA (Borehole Water Association of South Africa). This not only provides the info needed to select the right pump, but also allows us to certify your borehole in accordance with the SANS 10299-4:2003 specification.
Are they a member of the Borehole Water Association
Membership of the Association shows that the driller you are dealing with is committed to the long-term viability and professionalism of the industry and that the drilling company is part of a network of professionals that will ensure accountability.
Is the borehole company familiar with the area?
Working with a borehole company that has experience in your area is essential. Municipalities often have different rules regarding borehole drilling activities as well as when, how and if you need to register your borehole. Furthermore the type of sediment and rock could require more advanced drilling techniques which makes working with an area expert essential. Drilling into clay or dolomite for example comes with its own set of problems. If you work with a borehole company that knows the geological features of the area it will dramatically increase your chances of success.
How deep are boreholes in Gauteng usually?
There are multiple factors that influence the depth of a borehole, however in our experience most boreholes in Gauteng range between a depth of 48m-90m. Use that as a guide when getting quotes from suppliers.
