Esse service traz benefício para toda a cidade. Já me preparei para fazer a interligação porque, sem ela, o esgoto não segue para o caminho correto. É importante que cada um faça a sua parte para ajudar a preservar o Rio Cuiabá.

Community Impact and Resident Perspectives

The expansion of the sewage network has altered the daily lives of residents, particularly in the Jardim Eldorado neighborhood. The installation of Terminais de Inspeção e Limpeza (TIL) allowed for the interconnection of properties to the sewage system. This technical upgrade contributes to the preservation of the Cuiabá and Coxipó rivers and reduces risks to public health.

Local resident Reginaldo Cassiano dos Santos commented on the importance of the project. He stated that the service benefits the entire city and emphasized the necessity of individual property connections to ensure sewage flows correctly. He also highlighted the collective responsibility to help preserve the Cuiabá River.

Reginaldo Cassiano dos Santos, a resident of Jardim Eldorado, said: "Esse service traz benefício para toda a cidade. Já me preparei para fazer a interligação porque, sem ela, o esgoto não segue para o caminho correto. É importante que cada um faça a sua parte para ajudar a preservar o Rio Cuiabá."

New Treatment Plants and Future Projections

Beyond network expansion, Águas Cuiabá is advancing structural projects such as the Estação de Tratamento de Esgoto (ETE) Sul. Located in the Coxipó region, this facility is currently 35% complete. With an investment of R$ 29 million, the station is designed to treat 60 liters of sewage per second.

The ETE Sul is projected to benefit approximately 42,000 people. It aims to significantly improve the quality of treated sewage and reduce environmental impact. The project addresses a region that has experienced substantial growth in recent years.

Leonardo Menna, the General Director of Águas Cuiabá, noted that sanitation transforms the quality of life for the population. He explained that the ETE Sul will expand service coverage in a rapidly growing area of the city. Leonardo Menna, Director-General of Águas Cuiabá, said: "O saneamento transforma a qualidade de vida da população. Com a ETE Sul, vamos ampliar o atendimento em uma região que cresceu muito nos últimos anos."

National Recognition and Corporate Context

The impact of the company's work has been acknowledged on a national level. The Instituto Trata Brasil highlighted Cuiabá as the city that invested the most in basic sanitation over the last five years. This recognition reaffirms the concessionaire's commitment to sustainable urban development.

Águas Cuiabá operates under a full concession that began in 2012 and is valid for 38 years. The company officially assumed water supply and sanitation services in the capital of Mato Grosso in 2017. It currently serves 605,000 people with the objective of universalizing access to quality water and sewage collection and treatment.
