Dhaka Wasa unveils sewerage master plan
Dhaka Water Supply and Sewerage Authority (Wasa) has prepared a 23-year sewerage master plan to bring the whole Dhaka city under its network.
Currently only 30 percent of the capital is covered by the sewerage network, speakers said at a programme at Sonargaon Hotel yesterday where the plan was unveiled.
Due to an absence of sewerage system in the large parts of Dhaka city, waste is being dumped in rivers, canals and other water bodies, causing serious water pollution.
Wasa Managing Director Taqsem A Khan said the plan would be implemented in three phases at a cost of US$ 2 billion.
In the first phase, Pagla Sewerage Treatment Plant will be improved so that it can use its full capacity of treating 1.2 lakh cubic metres of waste. Currently it treats only 40,000 cubic metres of waste.
In addition, the trunk sewerage from Madhubagh (near Tejgaon) to Pagla will be rehabilitated and new sewerage system will be built in Gulshan and Banani area.
Wasa will also rehabilitate or construct four lift stations at Tejgaon, Gulshan, Bashabo and Golapbagh. The first phase will be implemented by 2015.
In the second phase to be completed by 2025, Wasa will construct four sewerage treatment plants in Dhaka and two in Narayanganj.
Five more treatment plants in Savar, Tongi, Keraniganj, Purbachal and Gazipur will be constructed in the third phase by 2035.
