READ MOREThe intention is to provide a broad overview of groundwater resources in terms of how it occurs (its distribution across South Africa)
as well as an overview of the complete “life cycle” of groundwater development projects (starting with drilling and on through yield testing; monitoring and all the way to the authorization of the use of groundwater).

READ MOREUsually, the preparations made for groundwater exploration, drilling, and testing the yield and quality of boreholes culminates in the registration or authorisation of the use of new groundwater. While Section 21 of the National Water Act No. 36 of 1998 guides the groundwater user in terms of the authorization process, there are various aspects that should be taken into consideration.

South Africa (SA) is a water scarce country that is characterised by extreme climatic conditions and evaporation rates that often exceed precipitation. The country is projected to have a 17% water supply deficit by 2030 (DWS, 2019). This can be mitigated by increasing water efficiency and diversifying water sources. By 2040, alternative sources such as […]

READ MOREWritten by Dale Barrow Drilling and having a borehole is an asset that should last you at least 10 to 15 years at very little ongoing cost, provided you do everything correctly at the start! If you don’t, it can become a very expensive and time-consuming liability with continual repair or replacement of pumps. The […]

READ MORERecognition of groundwater’s contribution to water supply, including garden irrigation, crop irrigation, stock watering, potable and town supply, is ever increasing. This is driven by inconsistent rainfall patterns, climate change and an increase in water demand. With drill rigs of all shapes and sizes running around between drill sites, it is appropriate that we spend some time outlining some important aspects regarding a successful borehole – it goes beyond just selecting the correct drill site!

READ MOREBy Kes Murray Understanding Groundwater recharging Managed Aquifer Recharge (MAR), sometimes referred to as Artificial Recharge, is the process by which a water source is intentionally injected or infiltrated into an aquifer. There are a wide variety of reasons for doing this, as well as a range of methods and technologies that are used to […]

How to correctly follow a borehole yield test? The South African National Standard for the test pumping of water boreholes (SANS 10299-4:2003) clearly prescribes how the borehole yield testing is to be carried out. Remember the Department of Water and Sanitation (DWS) will only authorise groundwater use if the correct (above) method of borehole yield […]

READ MOREThe land we live, work and walk on is the only one we have and therefore contamination from human activity and industrialisation is a real issue strongly linked to our common past, present and future. It is important to remember that contamination is something that has occurred in the past, is occurring in the present and it will occur in the future. It is therefore crucial that these concerns are addressed.

READ MOREJulian,
Klein Rondeboschje Drill 1. 70 000l at 72m. I stopped right there, and not going deeper. Will also only drill the one hole there. Steel casing all the way. Brackish, but usable. Tastes the same as the current water.
Thank you and well done!
