Your reply - it would be worse under ANC - is ignorant of management and government, irrelevant, DA misinformation, obfuscation, evasive, naive, desperate, blindly loyal to an incompetent DA, which you acknowledge holds truth, dishonest .... 
It's NOT relevant what the ANC would've have done because they're NOT running the city and haven't been for 11 years (!). The ONLY relevant and important factor is what the DA-run city ought to (not should have) done NO LATER than 12 months ago. But they didn't - they sat on their asses hoping and praying 2017's rains would be a deluge, which would've been a disaster on its own, to fill the dams. In the meantime, their A game consisted of restrictions against solely households while letting businesses, etc off. Eh? You don't run a city this way.
Put another way, your argument is like one where a plane's heading for an inevitable crash and passengers saying,  'It's a good thing the bad pilot is not flying today'. Good luck with that attitude.
