"Water and Environment Affairs said that if Cape Town did not start using less water than it does now, it would run into shortages by 2012."
"(The DA claimed) that the recently constructed Berg River Dam will extend the need for implementation of further new water projects to about 2020."

Now I'm not suggesting there hasn't been some potential mismanagement with regard to Cape Town's water, but the last time I checked the maths, 2017 is a fair bit closer to 2020 than it is to 2012, so I know who sounds like they were closer to correct (barring a rather nasty drought)...
