If data on water consumption is unavailable or unclear, even within the city, how can they declare, as they've been doing, households and watering gardens are to blame for high consumption and dropping dam levels? Household use was the main target of water restrictions, NOT bulk users like industries incl tourism, business and government. But these users, and reportedly old age homes and housing estates to water their gardens, got exemptions despite the seriousness of the situation evident in January already. 

Then and later I asked the director of water & sanitation, Xanthea Limberg, JP Smith and Patricia de Lille this and other questions. No answer. I suspected but these articles confirms my fears the city has manipulated and not revealed all the data (worse, they don't know) to hide their mismanagement of the crisis, eg they misjudged it hoping for early rain, and/or it's worse than we think. And THEY accused residents of 'politicising' the crisis, residents who'll bear the brunt.
