PSAM was developed by the Rio de Janeiro State Secretariat of Environment (SEA) in 2010 and is part of the Pact for Sanitation (State Decree 42.930/11) subprogram Rio+Clean. The program covers 15 municipalities around Guanabara Bay, including the City of Rio de Janeiro, and it focuses on basic sanitation actions in watersheds contributing to the Guanabara Bay. The PSAM is an important step to achieve key goals of the state: to universalize sanitation in the region and to advance the environmental restoration of the bay. This restoration goal is one of the State's commitments for the 2016 Olympic Games, since the Bay will host several contests during the competition.
The region covered by PSAM has previously received investments for Bay clean-up. Today, about 27% of the population in the region has been covered by past efforts to improve sewage treatment services. With the implementation of PSAM, sewage treatment service will reach 42% of the population total. The great challenge of a program of this scale is to adequately plan special interventions to implement sewage systems in areas that are already densely inhabited with high population growth, unplanned development, and significant favela (slum) presence.
PSAM is designed to contribute to the Pact by (among other works) building new sewage systems in Cidade Nova and Alcantara, correcting irregular sewage releases into the stormwater system, improving and expanding existing sewage systems in Saratoga and Pavuna, and eliminating the release of untreated domestic sewage into Guanabara Bay. The program will augment the State's previous investments in sanitation through the Guanabara Bay Decontamination Program and the Nova Baixada Program.
The Inter-American Development Bank has loaned the Rio de Janeiro State R$800 million to restore the Bay environment, supplementing R$330 million from Fecam. Further, R$570 million from the Growth Acceleration Program (PAC)will support sanitation works by the State Sewage and Water Company Cia Estadual de Águas e Esgotos (CEDAE) and the State Secretariat of Works over the next three years.
This program will improve water quality by decreasing runoff and direct releases of polluted water through improved sanitation and stormwater management. In addition, PSAM will improve the quality of life for residents of the affected municipalities by enhancing access to basic sanitation and reducing exposure to water-borne illness.
