Manaus wastes water equivalent to 80 Olympic swimming pools per day Disclosure Amazonas wastes the equivalent of 178 Olympic swimming pools of treated water every day before it reaches the population's taps. The data is from the "Water Loss Study 2025", released by Instituto Trata Brasil in partnership with the consultancy GO Associados, based on 2023 data from the National Basic Sanitation Information System (SINISA). According to the survey, 40.68% of treated water produced in the state is lost during distribution. In practice, of every 100 liters of water ready for consumption, more than 40 do not reach residents because of leaks, illegal connections, deviations or measurement failures. The index is close to the national average, which was 40.31% in 2023. 📲 Join the g1 AM channel on WhatsApp The study also estimates that the volume of water wasted daily in Amazonas would be enough to fill 591,716 residential water tanks with a capacity of 750 liters. Study shows that the country wastes enough water every year to supply 77 million Brazilians The waste occurs amid the climate challenges faced by the Amazon in recent years, with severe droughts and reduced river levels. According to the survey, if Amazonas reduced losses to 25%, a target established by the Federal Government for 2034, the volume of water recovered would be enough to supply around 874 thousand people. North has the worst rates in the country Although Amazonas has an index close to the national average, the North Region has the worst performance in Brazil in terms of water losses. In 2023, the region recorded an average waste of 49.78% of the water distributed. According to the study, the North and Northeast concentrate the biggest challenges in basic sanitation in the country. In addition to the high loss rates, the two regions also have the worst indicators for water supply, sewage collection and treatment. On the other hand, the North Region was the one that made the most progress in reducing losses in recent years. Between 2019 and 2023, there was a drop of 5.43 percentage points in the indicator. Even so, neighboring states such as Roraima (62.51%) and Acre (62.25%) continue to be among those that waste the most water in Brazil.

According to the study, when only physical losses are considered, caused by leaks and ruptures in the distribution network, the capital wastes the equivalent of 80 Olympic swimming pools of water per day. The volume increases when commercial losses, such as fraud, illegal connections and measurement errors, enter the account. In this scenario, the revenue loss rate reaches 47.49%, making total waste reach the equivalent of 113.28 Olympic swimming pools daily. According to the survey, if Manaus reached the target of 25% distribution losses, the volume of water recovered would be enough to supply around 719,700 people. Sought by g1, Águas de Manaus, the concessionaire responsible for water supply in the capital of Amazonas, reported that it had reduced the water loss rate from 74.95% to 45.25% in the last eight years, a drop of almost 30 percentage points. According to the company, the current percentage is close to the national average, 41%. The concessionaire attributes the result to investments of more than R$2.3 billion in expanding and modernizing the supply system. Among the actions carried out are the implementation of more than 200 kilometers of water networks in vulnerable areas and the creation of the Integrated Operations Center (COI), which monitors the system 24 hours a day and allows leaks to be identified more quickly. Águas de Manaus also informed that it intends to maintain investments in the coming years, focusing on modernizing the network, expanding supply in expansion areas of the city and continuing actions to reduce water losses.
