Dscc, wasa identify 48 waterlogging-prone areas dhaka tribune

Authorities are taking no effective measures other than ordering people to clean drains and reclaim grabbed rivers and canals. City dwellers are afraid of another waterlogging in the upcoming monsoon while the authorities seem indifferent to solving the problem.

According to the report, rainwater from Motijheel, Dilkusha, Doinik Bangla, Shantinagar, Malibagh, Mouchak, Segunbagicha, Paltan, Bailey Road, Siddheswari, Circuit House Road, Rajarbagh, Shantibagh, Fakirapul and Arambagh finds its way to the Balu and Buriganga Rivers through the Segunbagicha Box Culvert, Kamalapur Pump, Maniknagar canal, Jirani canal, and Manda canal.

Rainwater from Dhanmondi-27, Rapa Plaza, Dhanmondi-8/A Staff Quarters intersection, Kathal Bagan, Gastro Liver lane, Kalabagan Dolphin Lane, Green Road, Madartek, and Meradia, pass through the Panthapath Box Culvert, Hatirjheel, and Rampura canal, and finally end up in the Balu River.

Rainwater from Kaptan Bazar, Laxmibazar, and Agamasi Lane are drained through the English Road, Dholaikhal box culvert, ending up at the Sutrapur pump. Rainwater from Jurain, Postogola, Muradpur, Shyampur, Kodomtola and Doyaganj rail bridge are drained throughthe Zia Sarani canal, Rosulbagh, and Shimrail pump (Water Development Board), draining into the Shitalakshya river.

The report mentioned numerous reasons for waterlogging. The reasons include a decrease in the number of wetlands, filling up of rivers, drains and canals, faulty drainage systems or lack thereof , impediments to the drainage system due to utility lines, fewer natural water reservoirs, and drainage networks choked by garbage, and the lack of separate storm and waste sewer lines. Recommendations

The report came up with a number of recommendations including Was setting up a drainage network in collaboration with DSCC, putting in proper drain outlets and cleaning them on a regular basis, installing pipes for lanes and main roads based on the volume of water , setting up adequate drainage lines to accommodate heavy rainfall, constructing drains by following geographical locations, completing digging on time, filling up roads with sand after digging by various agencies, removing garbage immediately after collecting it from drains, reclaiming grabbed canals, setting up separate sewerage line in every neighbourhood, not piling up construction materials on the road, cleaning up box culverts, keeping open lowlands and marshlands, and setting up new water reservoirs.

Other recommendations are: setting up drainage infrastructure and their expansion where needed, maintaining catch pits, saucer drains, open drains, pipe drains, storm sewer lines and box culverts, installing separate sewage lines for rainwater and waste sewage lines, reclaiming natural reservoirs, rivers, canals, lakes and lowlands, preventing throwing of waste in drainage systems, raising public awareness, enforcing laws, stopping illegal grabbing of rivers and canals, conserving canals naturally instead of constructing box culverts, expanding canals and canal banks and making arrangements for big water reservoirs in pumping areas and increasing their capacity.

Haji Aolad Hossain, panchayet committee member of old Dhaka, said: “Every year mayors of the two city corporations, the managing director of Wasa and the local government minister speak a lot about resolving waterlogging. But we see no improvement. The city corporation should identify the waterlogged areas and take prompt measures.”

Apart from that, Dhaka Wasa has 10 km of box culverts, 65 km canals, four pumping stations and 346 km pipe drains (primary lines). Through these facilities, water goes to Dhanmondi lake, Jirani-Nandipur canal, Khilgaon-Basabo canals 1,2 and 3, Jirani canal, Hajaribagh canal, Dholaikhal, Segunbagicha canal 1 and 2, and Manda canal. DSCC water is drained to the Buriganga and Balu rivers through these canals.

Agencies which are working on reducing waterlogging in the city are Dhaka Wasa, DSCC, Dhaka North City Corporation (DNCC), Bangladesh Water Development Board, Bangladesh Inland Water Transport Authority, Rajdhani Unnayan Kartripakkha, and District Administration. Even after that, city dwellers face severe waterlogging during the monsoon.

Dhaka Wasa Managing Director, Taskim A Khan, said: “Dhaka now looks like a bucket due to the filling up of lowlands. That is why water has to be drained through pumping. We clean up canals and ponds every year. We have to set up artificial drains to resolve waterlogging in Dhaka.”

“Many donor agencies provide funds, alongside the annual budget allocation of Dhaka South City Corporation for maintenance, repair, and reconstruction of these drains. Despite these initiatives there is no significant improvement. Rather waterlogging is becoming severe every year.”

This year the Dhaka South City Corporation estimated a budget of Tk193 crore for constructing roads, footpaths and surface drains. Almost all the money is already spent. However, city dwellers anticipate there will be no respite from waterlogging in the coming monsoon.

“The ends of 8-10 canals in Dhaka have been blocked by housing companies. As a result there is no flowing canal. It will be of no use even after cleaning canals or drains if the ends are blocked and there is no water flow, which is why the city gets submerged after rainfall.”

Mubasshar further said: “The five drainage systems identified in the report are inadequate for this big city. We have been saying over and over that all service agencies will have to take coordinated initiatives to revive the water flow in these canals, drains, and rivers. We have to hand this over to an agency which will work on the matter. Otherwise we will not get rid of waterlogging.”

Prof Aktar Mahmud of the Urban and Regional Planning department at Jahangirnagar University, and vice president of Bangladesh Institute of Planners, said: “We have to implement the master plan of the 90s. Another master plan was made in 2015. But Dhaka Wasa has not published it.”
