Weekend Argus (Sunday Edition) - - NEWS - WEEK­END AR­GUS RE­PORTER

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.
