 The treatment plants will draw water from more distant and less polluted rivers up to 160 km from the city.The four plants are expected to have a combined capacity of 1.63 million cubic meters per year, compared to a 2010 supply of 2.11 million cubic meter per year that is mainly from groundwater.As of 2011, funding had been secured for the first plant which is under construction thanks to a US$250 million contribution from Danish development assistance.
