CAEP TOWN - With Day Zero fast approaching, schools are fearful of the scenario they may face.
If schools in the Western Cape have their taps turned off on Day Zero, 1.1 million children could be left stranded without water.
But Premier Helen Zille says that will not happen.
Schools will be categorised to differentiate their water needs.
Those closest to the CBD and hospitals won't be switched off at all while others will have water delivered or must rely on existing groundwater.
Not everyone is convinced.
"We must ensure that we don't have our school taps turned down during our periods when our learners are there," said SADTU Western Cape's Jonavon Rustin.
"We are greatly fearful about the fact that we may have huge health hazards. We cannot have huge outbreaks of diarrhoea in our institutions."
Zille reiterated that saving water can keep Day Zero away and is urging that only 20 litres per pupil per day be used during school hours.
