Before the concession was implemented, waterborne diseases in the city reached 56 cases per thousand inhabitants. These numbers have decreased dramatically with water treatment, reaching almost zero in 2019. In 2021, our main actions aimed at fighting the Covid-19 pandemic through the Crisis Committee established to propose health measures to employees and customers. Externally, the Niterói (RJ) utility company participated in a scientific study in 2021, in an agreement signed between the city of Niterói and the Oswaldo Cruz Foundation (Fiocruz), to quantify the inert viral load of SARS-Cov-2 in the municipality's wastewater networks. The follow-up helped the Health Department to monitor the progress of the virus. 6 CLEAN WATER AND SANITATION The Água de Valor program prevented an annual loss of 17.5 million m³ of water in less than three years, enough to supply a city of 260 thousand inhabitants, leaving our utility companies with losses lower than the country's average. In July 2021, we reached the universal sanitation in Jaú (SP), which became part of a very restricted group of Brazilian municipalities with 100% distribution of treated water and wastewater collection, sedimentation, and treatment. In Pará de Minas (MG), our utility company took the municipality to the fifth position in drinking water and basic sanitation in the 2021 ranking of the 17 Sustainable Development Goals (SDGs) of the United Nations Organization (UN), prepared by the Center for Public Leadership (CPL). In seven years of activities in the city, we went from a scenario of water shortage to being a reference in the country. In 2012, Votorantim (SP) had 62% of its municipal wastewater collected and treated; today, our utility company performs the collection and sedimentation of 99.37% of the city's wastewater and supplies 100% of the population with treated water. 5 GENDER EQUALITY Through our Diversity and Inclusion Committee, we work to meet the goals of women in senior leadership and as members of strategic committees. For 2021/2022, the Group has three new women on its board of directors and several others as superintendents, managers, coordinators, specialists, and other technical and operational positions. The Águas do Brasil Group joined the Empresa Cidadã Program (Citizen Company Program), which provides the extension of maternity leave from 120 days to 180, entitled to full compensation. 8 DECENT WORK AND ECONOMIC GROWTH In the municipality of Araruama (RJ), we promote social actions, such as EcoFibras, a pioneering initiative in the country that encourages manual weaving from aquatic plant residues from a treatment plant. There is also the Lagunarte project, which provides extra income for the fishing fam- ilies of the Araruama lagoon by training women in felt crafts. In March 2022, the project was extended to the municipality of Saquarema. Sustainability Report 2021 5
