Rumours of Rain – The incessant drought South Africa faces

2015 was the hottest driest year experienced by South Africa since records began in 1904. There is now little doubt that this is the result of toxic combination of “climate change” and the El Nino phenomenon. Currently Western Cape dams are at 30% full while those at Ceres and Clanwilliam are below 15%. Some major towns in the Free State, including Kroonstad, effectively have no water. While current conditions are bad enough, especially in the Free State, if sufficient rain doesn’t fall in the Western Cape this winter, coupled with below average rainfall on the Highveld from next spring, South Africa will be in the grip of a full blown crisis. Some months ago we reported on Southern Cold Store’s project to harvest rainwater, and mentioned that Australian cold stores do this as a matter of course.                     Cold and freezer stores need significant quantities of water, both as a cooling medium in condensers and for cleaning. Water prices have increased and pricing is being used to limit demand. By next year water may well be turned off for days at a time to conserve what’s left.   For all these reasons water tanks would appear to make a lot of sense, both to store harvested water and to create a reserve for days when there is no supply. If Western Cape cold stores move quickly they could have tanks installed to catch the last of any winter rains…

Should water tanks be a compulsory feature at all cold stores and warehouses?

At 54% the Western Cape dam levels are way down on last year. If it doesn’t improve soon there will be problems next summer. Water shortages are something that the Australian cold storage guys have experienced. Their big cold stores all have water tanks, I have seen them at both Oxford and Montague, where they find it profitable to use rain water (suitably treated) in the condensers. One of the tanks pictured below is for the sprinklers and they are not allowed to use this water for anything else, but the others catch rain water off the roof. As far as we know there are no cold stores in SA that do the same thing. With the low rainfalls we are surprised that this has not become a mandatory requirement. If there are any cold stores catching rain water we would be very interested to get more information. Please contact James Cunningham on email james@barpro.co.za
