São Paulo, Brazil’s drought-hit megacity of 20 million, has about 2 months of guaranteed water
RIO DE JANEIRO (Thomson Reuters Foundation) - São Paulo, Brazils drought-hit megacity of 20 million, has about two months of guaranteed water supply remaining as it taps into the second of three emergency reserves, officials say.
The city began using its second so-called technical reserve 10 days ago to prevent a water crisis after reservoirs reached critically low levels last month.
This is the first time the state has resorted to using the reserves, experts say.
If we take into account the same pattern of water extraction and rainfall that weve seen so far this month and its been raining less than half of the average we can say the (reserve) will last up to 60 days, said Marussia Whately, a water resources specialist at environmental NGO Instituto Socioambiental.
But an expected increase in water usage during the upcoming Christmas and New Years holidays could easily reduce the time the reserve will last, she added.
After that period, there is no certainty over the water supply available to Brazils wealthiest city and financial center, Whately said.
