Water privatization in Armenia – or, more accurately, the participation of private companies in the provision of water supply under contract with the government of Armenia – has been prepared since the mid-1990s. The first management contract for water supply in Armenia, covering the capital Yerevan, was signed in 1999 with financial support from the World Bank. As of 2010, almost 2.1 million people or about two thirds of the population of Armenia, including its entire urban population, received their drinking water from private companies. Sanitation is not included in the private sector contracts and remains a public responsibility.
