Work began in 2013 on what could be considered one of the venture’s great legacies for Altamira: basic sanitation for the city. Until then, there was no sewage treatment system and less than 10% of homes were supplied with potable water. The properties used cesspits for effluent disposal and wells for water.
Belo Monte transformed this reality. The venture built a modern waste collection and treatment system, with a network stretching over 200 km, and expanded the city's water catchment and supply system with a network spanning over 230 km. It is also connecting, at no cost to the residents, more than 19,000 properties to the sanitation networks.
At the municipal seat of Vitoria do Xingu, 29 kilometers of sewage lines, 12 kilometers of rainwater drainage lines and 12.8 kilometers of water lines were built. Two districts of the municipality were also benefited: Belo Monte, which received 220 meters of rainwater drainage lines and 2.3 kilometers of the sewage lines; and Leonardo da Vinci, where 9.8 km of sewage lines, 5.6 km of rainwater drainage lines, 12.8 km of treated water lines and 5.8 km of pavement were implemented.
In the municipality of Anapu, in the community of Belo Monte do Pontal, 320 meters of rainwater drainage lines and 4.3 kilometers of sewage lines were installed.
Three communities of Volta Grande do Xingu that belong to the territory of Senador José Porfírio also received sanitation works. In the community of Ressaca, Norte Energia completed 1.3 kilometers of water lines and 2.2 kilometers of sewage lines. In the Ilha da Fazenda community, 28 septic tanks, 28 sink pits and three biological filters were deployed. The Garimpo do Galo community received about 558 meters of sewage lines and 483 meters of water lines.
