Prime Minister Sheikh Hasina on Thursday (July 13, 2023) inaugurated the operation of South Asia's largest single sewage treatment plant in Dasherkandi near Dhaka's Aftabnagar.
The Dasherkandi Sewage Treatment Plant is the country's first modern STP and sludge drying-incinerator with capacity to treat 500 million litres sewage.
The inaugural ceremony was held at the Bangabandhu International Conference Center (BICC).
The plant will play an enormous role in preventing environment pollution and improving the water quality of Rampura canal, Balu River, Shitalakshya River and other water bodies, the authorities said.

Constructed on the East of Aftabnagar area, the plant is being hailed as a milestone in the country’s sewage treatment.
In the plant, some 45 metric tons of fly ash will be generated from sewage sludge a day, which can be used as raw materials in cement factories.
The Dasherkandi STP will treat sewage coming from a number of the city’s areas, including Tejgaon, Niketan, Badda, Banani, Gulshan (part), Banani, Ramna, Eskaton, Nayatola, Magbazar, Wireless, Mouchak, Outer Circular Road, Mohanagar Housing, Hatirjheel, Kalabagan and Dhanmondi (part).
The Dasherkandi plant will be able to treat 20-25 percent of the 2,000 million litre sewage generated in Dhaka city daily.
