'I cannot give a simple answer to the question of whether we will reach day zero' (NB De Lille: 'Day Zero is happening'). Experts say it will be by March 2018, with December or January critical http://features.dailymaverick.co.za/cape-of-storms-to-come. But you say your response here is based on what experts told you. Are the views of the experts quoted in the Chronicle article and video unknown to you when everyone in the country knows what they said? But still you imply there's doubt about IF (not when) the impending disaster will happen. 
You've taken it upon yourself to answer questions about a municipal competence, conflating and crossing those constitutional lines and spheres you mentioned, but when it suits you, you ring-fence your culpability to "I applied to have the WC declared a disaster area". Everybody, except DA, knows the city ought to have acted no later than 12 months ago with alternatives, NOT a few months ago. Why do you continue dissembling when the game's up?
