Visitors to Cape Town in South Africa are being warned that drinking water might be restricted from July due to the prolonged drought, which has already led to water-saving measures being introduced across the city.
Level 6B restrictions make it compulsory for residents to use no more than 50 litres per person per day.
But Capetonians are not yet out of the woods.
"I urge the residents of Cape Town not to ease up on their water-saving efforts‚" he said.
The city says its preparations for Day Zero continue, along with the roll-out of pressure management initiatives and the installation of water management devices at the properties of high water users across the metro.
Neilson also attributed the push back to a "further reduction" in the city's weekly water consumption rate, which now stands at around 520-million litres per day. "Last year we had abnormally low winter rainfall‚ and we can not assume that this year will be any different".
Water consumption averaged 523 megalitres per day (MLD) which, although significantly better that the 1 130MLD in 2014, was way off the target of 450MLD.
He said that Safa could not cancel matches or furtherreduce its water consumption: "We have made sacrifices and to be honest with you, it doesn't look like the City (of Cape Town) has a plan in place".
"Day Zero", when the reservoirs serving the town are expected to fall to just 13% of their capacity, has been pushed back several times from April to July.
But officials have been criticised for failing to implement usage restrictions sooner, and accused of ignoring warnings by experts in the years before the drought.
Cape Town, which attracts about two million visitors each year, wants to become more resilient as the effects of climate change are felt, similar to other dry cities including Melbourne and California.
