Greater São Paulo currently spends 15% less water than in 2013, a period before the crisis, according to Sabesp. However, according to data obtained through the Access to Information Act, compared to the first quarter of 2015, after the 2014 crisis, consumption increased by 15.4% over the same period in 2018.
- January to March 2015: 220.6 million m³
- From January to March 2018: 254.6 million m³
If we take into account the average amount per Person consumed daily:
- In 2013: 169 liters per day
- In 2017: 129 liters per day
- In 2016: 129 liters per day
- In 2017: 126 liters per day
- One of reasons to reduce consumption is the change in habits in condominiums, who feared rationing during the water crisis. In May 2014, the volume of the Cantareira system reached 29.6% of its capacity and Sabesp began to operate by pumping water from its dead volume.
After the crisis, experts point out that the reuse of water to clean the common areas of the condominium, for example, have remained in the past four years.
Other more personal habits, such as the duration of the bath, may be responsible for the increase in consumption. After the crisis, the paulista may have resumed his habits and returned to spend more water.
"Good habits have been maintained, especially in condos People have started to save more, but Sabesp and the government deny the seriousness of the situation, some people relax and end up spending more," says Pedro Luiz Coast, geologist and professor at the USP.
Actions like not sweeping the sidewalk with a hose, turning off the tap while brushing your teeth and taking quicker baths have become a part of the routine of Paulistas and also have an impact on the pocket.The reduction in the value of the account is one of the reasons for the new consumer behavior, according to Hubert Gebara, vice president of property management and condominiums at Secovi-SP ( Union of Housing)
"The lack of water in the crisis has frightened the population: nowadays, people are more aware, they know that water is not a good infinite and that if we do not p let's not give up, she'll finish. I'm sure that playing with the pocket has also made all the difference, "he says.
According to Gebara, individual water meters have been installed in about 200 condominiums in the city of São Paulo in the last four years. The device that measures the individual consumption of each apartment can reduce the water bill up to 30%, according to the expert.
After 46 days of drought, the capital of São Paulo recorded rains on Monday night (30). In July of last year, it rained almost twice as much as this month: 2.1 mm of rain was recorded.
Due to lack of rainfall, water must be saved. The city of São Paulo has enacted a new law Saturday (28) that amends those who wash the pavement with drinking water and treated. Only the water of reuse can be used. Sabesp agents will carry out the inspection. The fine is R $ 250 for anyone caught, and double for repeat offenders.
Since the 2014 water crisis, Sabesp has carried out large, medium and small scale works and actions to ensure more water for the population. But according to the Côrtes, the population must continue to do their part and save water.
"These works are encouraging, they somewhat reduce the impact of an adverse climatic situation, but we can not negotiate with the climate and the rains, so I think that it is necessary to strengthen for the population the actual situation of the fountains and the good habits of consumption of water to reduce the impact of a possible crisis. "
The level of the reservoirs worries
In addition from dry weather and pollution, the level of reservoirs that supply the state is worrisome because it falls daily. The Cantareira system, responsible for the supply of about 40% of Greater São Paulo, was on alert at the second, operating at 39.7% of its capacity.
In practice, the state of alert (equal to or lower than 40%) reduces the amount of water that Sabesp can withdraw from the spring of 31,000 liters per second to 27,000 liters per second .
On July 26, 2013, the year of the pre-crisis of the offer, the index was better: 53.8%.
The Guarapiranga dam also had a better situation in 2013. That year, its capacity was 91.2%. Today, it has 63.8%.
Sabesp says that the interconnection works of the rivers and the construction of the São Lourenço system, inaugurated in April, are enough to compensate for the emptying of the reservoirs.
