On this matter, how many WC government's facilities installed 'water efficient parts and technologies' restrictions have required since level 3 and if the message to conserve has been delivered to employees. I was at a WC facility this month and if that's typical, they've done little except marketing http://www.politicsweb.co.za/politics/wcape-govt-leading-way-in-water-and-electricity-sa. The same applies to city and government facilities. 
Don't defend the DA and Zille especially. Her supporters believe she's the Oracle. Politicians don't have the answers, and never have. But to get our vote they lie and tell us what they want us to believe. She could've taken this opportunity and given the bald truth - that we're in deep trouble and why but chose to blame the public, drought and government, exposing the true politician beneath her allegedly honest words. This makes me mad. The situation is beyond politicising and she's contributing to it. 
She knows what the 'serious' issues are.
