Believed to be the remnants of Shahjada Azimusshan's palace at Posta (extinct during company period)
Dhaka city dwellers remember with gratitude the name of
Nawab Khawaja Abdul Ghani for his role in the creation of
Water Works at Chandnighat to supply potable water in the city, most notable among his many philanthropic works. The work was started in
1874 with his contribution of over
Tk. 2,00,000 and
Lord Northbrook laid the foundation stone. In
1878, it became possible to supply drinking water in the town processed through hygienic filtration. Before this, people used water for consumption from river, canals and kutcha wells (paatkua) filled with filth and contaminated germs. Out-break of various diseases in epidemic year after year was common.
The plant established in 19th century now lies hidden amid unplanned jungle of buildings in old Dhaka between
Lalbagh Fort and Chawkbazar. The road (water works road) passes through part of Posta, Rahmatganj, Kanshar-hatta, Chandnighat and Churi-hatta. The open space east of Water Works plant beside the riverbank where
“Chandni”, the Royal boat of Mughal
Subahder Islam Khan moored, is now a slum. Water of
Buriganga river for the plant is drawn near this point.
This plant, with its subsequent improvement, supplies 39 million litres of filtered water daily which meets 1.8% of the total water supply of Dhaka. Tanneries and industrial units of Rayerbazar and Hazaribagh everyday pour millions of liters of untreated, highly toxic liquid wastes into the river. Buriganga water around Dhaka has become poisonous and looks pitch black with intolerable stench. It is hardly possible to treat polluted river water to make it fit for human consumption any more. Fortunately, 82% of potable water of Dhaka is drawn from underground source by over 400 production wells, but this source is drying up fast with the falling of underwater table.
