At the western part and the southeast part of Chattogram city, including Halishahar catchment area about 34.83 square km, Halishahar, Rampur, Agrabad to construct faecal sludge collection, transportation and treatment system are 300 cubic meter per day at halishahar catchment area and other parts of the city, wherever sewerage facility cannot be provided because of constraint in infrastructure construction space, and on-side sanitation improvement at different parts of the city including slums.
The ECNEC meeting has approved the Tk 3808 crore project for Chattogram WASA. Of the total cost, the government will provide Tk3758 crore while the rest Tk 50 crore will be provided by the CWASA. The aim of the project is to solve sewerage disposal problems in the port city.
Talking to the Daily Observer, Project Director Ariful Islam said that the total project would be completed in six catchments.
He said, the works of the first catchment will begin in June next year. After completion of the project in 2023, there will be no need of septic tanks in any building in the city as all household septic dirt will directly go to sewerage treatment plant rather the Karnaphuli River. The sewage treatment plant will be set up on 165 acres of land in city's Halishahar area.
Since its inception in 1963, the CWASA did not take measures to solve sewage problem. But the present Awami League government has taken up the project.
The project will be implemented in phases dividing the city into six zones. A total of six plants will be installed in the zones. Besides, human excreta and other wastage of septic tanks of nearly 70 lakh people of city directly fall into the river Karnaphuli.
One lakh out of six lakh slum families have no access to sanitary latrine and they discharge their excreta through 'kucca' makeshift latrine set up alongside various water bodies. The CWASA started its activities with the supply of 16 million litres of water through 19 deep tube wells, but without sewer system, but without sewer system.
More than 700 numbers of small and heavy industries have been developed on both sides of the Karnaphuli River. The pollutants and wastage of those industries are directly flowing down to the river polluting it heavily.
