The Borehole Water Journal Online is a trade publication for the southern African groundwater industry. It is aimed at decision-makers and end-users in the groundwater industry, particularly in the public service, mining and consulting industry.
Ensuring optimum system performance from a groundwater installation in sandy conditions requires planning and specific skills. This article explains the implications of pumping water with a high TSS value, and what can be done if you are faced with a "sandy borehole".
Read MoreJohn Tonkin has written a series of three articles aimed at ensuring a long and cost-effective borehole pump installation. He looks at Non-Return Valves (NRVs); submersible motors and Root Cause Analysis (RCA) and remedial strategies.
Read MoreMost popular article in 2019 based on page views! To alleviate the strain on municipal water, many municipalities are encouraging home owners to drill boreholes on their properties. But what should end-users consider before making this investment? In this article, we give an overview of some of the aspects you should consider.

Read MoreNational Groundwater Information System (NGIS) is a portfolio of projects designed to meet increasing demands for groundwater information in a rapidly changing water business environment. The portfolio of the NGIS project includes several applications, namely NGA, CHART and the Geohydrological Reports System.
Read MoreAll too often when a pump stops delivering water it is removed, repaired and reinstalled in the same conditions. A detailed and careful look at the performance history of the installation and the symptoms of failure will lead to corrective or remedial actions being taken to prevent a similar failure from occurring in the future. This process is known as a Root Cause Analysis.
