Water privatization in Brazil has been initiated in 1996. In 2008 private companies provided 7 million Brazilians - 4% of the urban population - in 10 of the country’s 26 states with drinking water. The private sector holds 65 concession contracts in the states of São Paulo, Rio de Janeiro, Espírito Santo, Mato Grosso, Mato Grosso do Sul, Santa Catarina, Minas Gerais, Paraná, Pará and Amazonas. Private companies have committed to invest 4.5 billion reais (US$ 2.8 bn) in the sector. The bulk of Brazil’s population receives water and sanitation services from public municipal or state-level utilities (see Water supply and sanitation in Brazil).
