Chattogram is the second largest city of Bangladesh. Since 1971, the population of the city has grown from about 0.5 million to more than 4.0 million in 2017. The city area has also expanded. The total area of Chattogram and suburban areas (including proposed Hathazari and Sitakunda) is around 270 sq. km. Between 1974 (77 sq. km.) and 2007, the built-up area has increased by around 250%.
This kind of growth presents tremendous challenges to the utility authorities in providing utility services. CWASA is striving hard to keep pace with the city development.
