Environment Adviser Syeda Rizwana Hasan today said there is no alternative to excavating the canals to solve Dhaka's waterlogging issues and restoration of water flow in the canals is a must.

During a visit in Baunia canal at Mirpur and Khidir canal at Uttara, she said that preserving these canals is essential to maintaining the city's biodiversity.

She also said, "Dhaka North City Corporation has already begun excavating six canals, and by the end of this year, a total of 19 canals will be restored. This initiative will not only prevent flooding but also help replenish the groundwater level."

DNCC administrator Mohammad Azaz said, "We have taken initiatives to recover and excavate canals, alongside eviction drives to remove illegal encroachments. The progress of these development activities is already visible. Additionally, to prevent water pollution, we are working to disconnect untreated sewage lines from buildings."

He said they have met leaders from Gulshan, Banani, and Baridhara societies, instructing them to install ETPs (Effluent Treatment Plants) in every building within a short timeframe.

Meanwhile, DNCC and DSCC have launched a restoration programme for 19 canals. The first phase, which started on February 2 involves restoring six canals -- four in DNCC (Baunia, Karail, Rupnagar, and Begunbari) and two in DSCC (Manda and Kalunagar).

The programme includes boundary demarcation, canal cleaning, bank protection, and the development of a blue network to enhance water flow and connectivity across the city.
