"Cleaning up the Citarum river and its 22 streams has been classified a national priority by the Indonesian government, which in 2010 launched a huge 15-year project to rehabilitate the river. Largely financed by the private sector, this “road map” involves dozens of NGOs, seven ministries and 12 local governments, amounting to a total of $3.5 billion. The Asian Development Bank (ADB) will contribute $500 million." (Quoted from article)
