The residents of Dhaka continue to suffer significant hardships due to waterlogging, a problem exacerbated by the blame game among various government agencies. This recurring issue surfaces whenever there is sustained rainfall, leaving residents to deal with the aftermath. The root cause lies in the inadequate coordination between the two city corporations and other government agencies responsible for maintaining the drainage system in Dhaka. There is a noticeable lack of attention to maintaining the cleanliness of the city's canals and sewers.
The stagnant water in the capital typically drains into surrounding rivers through three channels: a pump station, sluice gates, and canals. However, most of the sluice gates under Dhaka South City are not functional, and the canals are inadequate for efficient water flow, perpetuating the annual flooding woes for the city's residents. The Dhaka North City Corporation (DNCC) has 1,250 km of drainage lines, and the Dhaka South City Corporation (DSCC) has 961 km. Despite the existence of 26 canals under the two city corporations, the lack of maintenance is causing these water bodies to fill up. Moreover, canals are being filled with trash as people dump polythene, bottles, and debris, which end up in the drains and obstruct water flow.
To address Dhaka's drainage issues, it's essential to halt unplanned urbanisation by enforcing strict regulations and improve coordination among authorities responsible for maintaining the drainage systems. Implementing storm drainage easements and conducting regular inspections and maintenance are crucial steps. Additionally, developing skilled personnel, acquiring adequate machinery, providing appropriate training, and ensuring safety measures are necessary for proper maintenance and waste disposal.
The Detailed Area Plan (DAP) should be implemented without delay, and all ongoing drainage-related projects across all agencies must be completed urgently before the next monsoon season. A comprehensive and integrated drainage master plan with short- and long-term targets should be prepared, incorporating solid waste management and sustainable sewer network management. Furthermore, public participation must be ensured in keeping their surroundings clean.
