Maceió wastes 60% of its drinking water.
According to the Trata Brasil Institute, 60% of treated drinking water is wasted in Maceió; water losses are due to leaks, measurement errors, illegal connections, and other irregularities; data was collected between 2011 and 2012; regarding sewage, less than 40% is treated; the survey also shows that in 62 of the 100 Brazilian cities analyzed, between 30% and 60% of treated drinking water was lost; in Porto Velho and Macapá, for example, for every 10 liters of water produced, 7 were lost; only four cities managed to keep losses below 15%.
Alagoas247 - A survey conducted by the Trata Brasil Institute shows that Maceió is among the Brazilian capitals that lose the most treated water for consumption. The waste reaches 60%, and the data was collected between 2011 and 2012. The capital of Alagoas state has hardly reduced this loss during this period.
To make matters worse, Maceió treats less than 40% of the sewage produced, dumping the rest into nature, according to a study released this Wednesday (27). The percentage stands at 38,75% and also corresponds to the years 2011 and 2012.
According to the institute, water losses are due to leaks, measurement errors, illegal connections, and other irregularities. Of the 100 largest Brazilian cities, 90 failed to reduce water losses. In these municipalities, the reduction in losses was zero or up to 10%.
The data for the study comes from the National Sanitation Information System (SNIS), of the Ministry of Cities. The latest update refers to 2012.
The ranking considers water loss to be water that was treated and supplied for consumption, but which was not billed for because it was lost through leaks, stolen through illegal connections, or due to measurement errors. Without a return on the money spent on energy and chemicals to treat the water, companies invest less in improving the system.
According to the survey, in 62 of the 100 cities analyzed, between 30% and 60% of the treated water intended for consumption was lost in 2012. In cities like Porto Velho and Macapá, for every 10 liters of water produced, 7 were lost. Only four cities managed to keep losses below 15%.
Since 2009, the Trata Brasil Institute has been producing a ranking that assesses basic sanitation conditions in 100 Brazilian cities with more than 250 inhabitants. Criteria such as the drinking water supply network, sewage collection and treatment, and water losses are analyzed.
Sanitation
The sanitation ranking shows the situation of 100 Brazilian municipalities with more than 250 inhabitants and is based on data from the National Sanitation Information System (SNIS) of the Ministry of Cities. The latest update refers to the year 2012.
According to the institute, the equivalent of 2.959 swimming pools of sewage were dumped into the environment every day in 2012 due to the lack of treatment services in these cities. Each pool holds at least 2,5 million liters.
The survey has been conducted since 2009 and also considers factors such as the percentage of the population supplied with potable water and the loss of this resource in the sanitation system. The study's data indicate that sewage treatment is still not a priority for public administrations. In 29 of the municipalities, sewage collection services reached less than half of the population in 2012.
