Rio de Janeiro state water and sewerage utility Companhia Estadual de Águas e Esgotos (Cedae) was founded in 1975 as a result of the merger between Empresa de Águas do Estado da Guanabara (Cedag), Empresa de Saneamento da Guanabara (Esag) and Companhia de Saneamento do Estado do Rio de Janeiro (Sanerj). It is engaged in operating and maintaining the state's water distribution systems, including water collection, treatment and supply, as well as the collection, transport, treatment and disposal of wastewater generated by 65 of the state's municipalities within its coverage area. Cedae also develops water quality projects, such as the Guandu II hydro project, which includes building 12 pumping stations, 10 reservoirs and a 495km pipeline to increase the state's water treatment capacity to 42Ml.
