Why is "Water privatization in Colombia" trending?

Wikipedia Overview

Private sector participation in water supply and sanitation in Colombia has been more stable and successful than in some other Latin American countries such as Argentina or Bolivia. According to the World Bank, between 1996 and 2007, more than 40 water and sanitation service provision contracts have been awarded to private or mixed companies in Colombia, serving a combined population of 7.3 million or more than 20% of the urban population. According to the Colombian water regulator, there were even more public-private partnerships for water and sanitation in Colombia in 2004: 125 private and 48 mixed public-private water companies, including large, medium and small companies. Most of the contracts were awarded in poor municipalities with highly deteriorated infrastructure. They relied mainly on public funding, complemented by limited private funding. The design was based on the central government providing grants in the start-up years to rehabilitate deteriorated systems and to expand access, while the contracting municipal governments also made budgetary transfers on an annual basis to complement revenues. Colombia thus departed from the standard concession approach, which requires private concessionaires to finance investments with their own resources.
