Aquifier, desalination plans outlined
AT A full council meeting this week, Cape Town mayor Patricia de Lille provided details of the City’s water augmentation plans.
She said four sites had been identified for groundwater abstraction, for which planning was “well under way” to get supply from aquifiers at Atlantis and Silwerstroom, Cape Flats, the Cape Peninsula and Hottentots-Holland.
“Over time, the yield extracted from these sources will rise to 100 million litres of water per day … The city has already managed to increase the production capacity of the existing Atlantis and Silwerstroom Aquifer by five million litres of water per day.”
De Lille added that there were seven tenders currently at various stages of the procurement process.
In terms of desalination, eight tenders are in progress for modular, land-based plants in Hout Bay, which will produce four million litres per day; Granger Bay, which will produce eight million per day; Red Hill/Dido Valley, which will produce two million; Strandfontein and Monwabisi, which will both produce seven million; Harmony Park, which will produce eight million; and Cape Town Harbour, which will produce 50 million.
“Water from the desalination sites will be increased incrementally in the system from February,” she said, adding that desalination from Cape Town harbour barges would yield its first water in April 2018, by augmenting up to 50 million litres per day.
