Cape Town International Convention Centre (CTICC) has commissioned its own reverse osmosis plant, which will draw on underground seawater.

The project, which is expected to cost around R8m, is in the testing phase and the CTICC is “in the process of fine-tuning the extraction and purification process”, it says in a statement.

“The plant will draw underground seawater using ultra filtration and reverse osmosis technology that removes the salt and contaminants from the water by pushing it through a semi-permeable membrane at high pressure. This produces fully potable drinking water that will comply with the SANS 241 of 2015 Standard for Drinking Water,” the statement reads.

It is expected that around 200 000F can be produced by plant in any 24-hour cycle, and additional storage tanks with a capacity of 400 000F will allow the centre to cater for all potential maximum demand scenarios­.

The CTICC carefully monitors its water consumption “With CTICC 2 opened, we have started measuring both our buildings and have calculated that a combined water usage for CTICC 1 and CTICC 2 stands at 125 000F per day,” says CTICC spokesperson Nadine Christians.

CTICC CEO Julie-May Ellingson says in the statement: “The plant, in conjunction with our water storage capacity, will provide five times our average daily water consumption, thus ensuring that the CTICC can offer 100% water-neutral events.”

Christians adds: “The CTICC only uses water when we absolutely need to. We will only produce water when and if we need it and we carefully manage the amount of water we use in both buildings and during the events we host.”

The CTICC currently runs several water-saving initiatives, including rainwater storage tanks, capturing the condensate from the air-conditioning units, water-saving information boards, and the installation of water-smart showerheads in the centre’s meeting suites and aerators for taps in kitchens.Christians says: “The CTICC has implemented several initiatives in the operation of the business to save water and lower our water usage.”
