This is the third volume of the Borehole Water Journal Online (BWJO). The metrics for Volumes 101 and 102 have been nothing short of amazing. 6300 visitors, of which an estimated 4760 were distinct people, did 17 250 page views!
The editorial policy has and always will be that this publication will be a vehicle for the dissemination of information aimed at the upliftment of the industry. Our content therefore offers answers to questions posed by end users, contractors, suppliers and groundwater professionals.
All aspects of the energy question continue to gain significant attention from people in all walks of life. In this edition we have two articles that take a closer look at this vital aspect of our lives (imagine a world without electricity). Our feature article, Making Cents of a Borehole Installation, shows how the cost of water, drawn from a borehole, increases dramatically as drawdown increases. Our next article tackles the folly of throttling pumps in order to achieve a required flow rate. Read Throttle your pump, throttle your profits.
We also have an article that looks at the impact that mining has on groundwater in Sydney Australia, using laser technology. While this is geographically far from SA, there are more similarities in the mining/groundwater interaction between the two countries than there are differences. The opportunities are therefore ever present to learn from how conflicts of interest are handled elsewhere in the world.
Then in To register or not to register…? Permitted water use explained in terms of the National Water Act, we take a close look at the often-queried problem of registration of boreholes and the requirements for the granting of a water usage license. The author, Ernst Bertram, recently retired from civil service and provides a valuable insight into the legal requirements for the drilling of a borehole.
In the Groundwater News section, there's a roundup of some of the groundwater-related stories making headlines, as well as news items on the WISA Conference, borehole water usage at a large shopping mall, and the history of Joburg's water supply.
Do you have an article to submit for the next volume of the Journal? The focus will be on solar energy, so articles on the application of solar energy will be particularly welcomed. Read our guidelines for article submissions and please submit any articles that will contribute to the professionalism of the groundwater industry.
