Dhaka, the capital of Bangladesh, is one of world's most populated cities. ‘Dhaka City’ is defined in this report as the areas under the jurisdiction of the two Dhaka City Corporations. They cover an approximate area of 120 sq. km and house a population of 6.8 million people. The number of open defecators is low (less than 1%), but a majority of the city’s excreta is discharged into the environment without treatment via open drains (70%). Although 28% of excreta is discharged to sewers, very little is delivered to the sewage treatment plant and less than 1% is effectively treated. This means that more than 99% of excreta is unsafely managed in Dhaka.
