“We dug a well under the hotel to access the water source. This allows us to pump enough water for our reverse osmosis plant to keep our hotel’s fresh water tank full at all times,” says Gary Bowers, the engineer who designed the desalination unit. It is capable of supplying 7 m3 of fresh water per hour from a 100 m deep borehole.
The use of a desalination plant means that we can no longer operate from municipal water supplies. In this way, we are able to play our role in saving water during this period of scarcity. Our customers can be assured that they do not put pressure on the local water supply when they stay with us,” says Clinton Thom, General Manager of Radisson Blu in Granger Bay.
The hotel is not the only structure to have disconnected from the drinking water distribution network in Cape Town. In August 2018, Lucky Star, a producer of canned fish, commissioned two seawater desalination plants in Laaiplek and Amawandle Pelagic on the west coast of South Africa. The treated water is intended for fish canning plants. Both plants were built by the South African company ImproChem in partnership with Suez Water Technologies & Solutions, a subsidiary of the French group Suez. They both provide 624 m3 of fresh water per day.
