The report shows that only 3% of the country's news inquiries were surveyed


A report from the National Water Agency shows that only 3% of the country's prey were surveyed by inspection agencies.

There are more than 24 thousand dams scattered throughout Brazil. According to the latest report from the National Water Agency, published in November 2018, there has been an increase compared to 2016. But the agency estimates that this figure is three times as much Great, since most of the country's reservoirs have not yet been registered.

Of the reservoirs that appear in the report, most are for irrigation, consumption of animals, fish farming and water supply. There are 790 reservoirs for the containment of mineral waste, such as the one that broke on Friday (25).

A worrying fact is that more than 40% of these structures are irregular, that is, they do not have any type of authorization, concession or license to operate. In total, 31 state and federal agencies participate in the supervision. It seems a lot, but if you have to add all the employees of these bodies, there are only 154 in the whole country.

To make things worse, only 20 of these agencies actually surveyed the year 2017. The result is that inspections only reached 3% of the country's prey. At this rate, it would take 30 years for all the prey recorded in Brazil to be interrogated at least once.

"We have obvious deficiencies in supervision. I am speaking at the federal and state levels. People are missing. Therefore, we must compose the tax boards and we must give cars and planes, helicopters, so they can carry out efficiently checking "says Alberto Sayão, professor of geotechnical engineering at PUC-Rio.

JN: Is it possible to completely eliminate the risk of an accident involving a prey?

Alberto Sayão: No. There is no. There is no zero risk engineering structure. There will always be. It is a cost problem. How much do you want to pay to improve, reduce the risk.

Shortly after the Mariana tragedy (MG), federal agencies doubled the number of inspections. But in 2017, they fell dramatically. The explanation of this was the reduction of the number of operations of the National Mining Agency.

According to the report of the National Water Agency, 723 shots were classified at the same time as a high risk and associated high potential harm.

The national security policy of the prey states that all structures with a high potential damage must have an emergency action plan, but 75% of those who should be planning in the country still do not have one

In 2016, after Mariana's tragedy, a commission from the Senate created to discuss the matter concluded that the execution was defective. As of here, a bill was presented to make the security policy of the prey more rigorous. But the proposal was not voted on. In the Chamber, five projects on the subject are on foot.

"Legislation is fundamental. So you have to learn from mistakes and take a stand to prevent these errors from occurring again. Obviously, it strengthens the execution a bit, improves. The increase in punishment It improves because the professional who agrees to do something will think twice before doing so. There is a series of aspects that can be improved in the sense of having more security in this type of projects, "says Maurício Erlich, professor of Civil Engineering at Coppe / UFRJ.

The national newspaper tried to hear the National Mining Agency about the reduction of prey inspections in 2017, but there was no response.
