From the year 2006, there is no progress in the water supply and sewerage projects for the city having more than twenty million population.In 2006 JICA in its study had pointed out the shortage of water by 400 million gallon daily in the city. Greater Karachi Water Supply project K-IV and Greater Karachi Sewerage project S-III could not be executed for non-availability of funds, he said.He said lakes are the source of water supply to the city.
