City of Cape Town’s water and energy efficiency chief has revealed that the city could run out of water before the year ends as reserves fell below 30 per cent.

COT's Sarah Rushmere, speaking at a water-themed hackathon event at Woodstock’s Rise Cape Town, Rushmere saus that even with the City’s current water restrictions, system maintenance and other measures in place,the city still isn’t saving enough, reports Cape Business News.

“People are using a third less water than they would a few summers ago. But it’s not enough,” she said.

The city, which is currently under the blanket of Level 3B water restrictions, has just 28 per cent capacity remaining in its 15 dams at the last count. Experts say just 18 per cent of that is fit for consumption.

The Cape Business News report says that at present, current consumption rates - which is well above the 700-million litres per day threshold - water stores will be flushed by June 2017, though restrictions will extend this to July.

Below 20 per cent storage, the City will “decrease water pressure in the network” and will increase the severity of water restrictions. Below 15 per cent, “intermittent supply” is planned. Beyond that, the City of Cape Town will enforce “lifeline water supply” measures, which will involve “minimal supply pressures, intermittent supply, and very stringent restriction measures”.

A report by the World Water Day by the World Wildlife Fund (WWF) released last week warned that water demand is expected to exceed supply in South Africa by 17 per cent in 2030, according to a report released on the eve of World Water Day by the World Wildlife Fund (WWF), in partnership with the Boston Consulting Group (BCG).

The report, prepared with the Boston Consulting Group (BCG), blames high water usage on the agriculture sector, which uses around 63 per cent of water, followed by the municipal and industrial sectors above public consumption.

"Water is not something we can assume will be there when we need it, at the quality we need it," said Christine Colvin, senior manager in the fresh water unit at WWF. "Climate change is expected to result in more erratic supplies of water so that means we need to get ready to do more with less,"
