Prime Minister Sheikh Hasina today inaugurated the operation of South Asia's largest single sewage treatment plant in Dasherkandi near the city's Aftabnagar.

The Dasherkandi Sewage Treatment Plant is the country's first modern STP and sludge drying-incinerator with a capacity to treat 500 million litres of 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 tonnes 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.

The plant has been built as part of a master plan taken up by WASA to construct five STPs to treat 100 percent of the sewage generated in Dhaka, in a modern and environment-friendly way, Dhaka WASA Managing Director Taqsem A Khan told reporters on Tuesday.

The four other modern sewage treatment plants will be constructed in Pagla, Rayerbazar, Uttara and Mirpur aiming to gain the capacity to treat 100 percent sewage of Dhaka city by 2030.

When the Pagla sewage treatment plant is completed, some 40 percent of sewages generated in Dhaka can be treated.
