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.
All 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.
Read MoreOne of the barges used by SpaceX to land the first stage of their boosters on is called Just Read The Instructions. I guess this name comes from the distinct possibility that we all are guilty of “If at first you do not succeed, read the instructions”. The cost of failure varies in direct proportion to the capital cost AND the thickness of the instruction manual and this is one such story. Bear with me as it has a happy ending.
Read MoreHow many pumping systems are designed on a single duty point? If many of the authoritative statistics that come out of the market are to be believed … a lot! Pump selections are about a range of duty points.

Read MoreIt's not flashy, but a careful study of system curves is going to help you realise savings that are out of all proportion to the input costs. During a recent energy audit of a river pump station, the vital importance of system curves was clearly demonstrated.

Read MoreThrottling pumps by using valves is a common practice in many plants. But it is far from an ideal practice, particularly because of the energy (and monetary) losses it involves.
