The Bangladesh Ministry of Water Resources said on Sunday that Dhaka has allowed Delhi to withdraw water from the Feni river on "humanitarian grounds."
The prime minister gave her assent to the deal as a "good neighbour" and the amount of water allocated for India is "too little," said a press release.
Prime Minister Sheikh Hasina and her Indian counterpart Narendra Modi held a top-level bilateral meeting in Delhi on Saturday, following which the two countries signed four Memoranda of Understanding.
Among those, a Memorandum of Understanding allows India to withdraw 1.82 cusec of water from the Feni river to be used as drinking water for residents of Sabroom town in Tripura.
The Ministry of Water Resources explained, "Some 1.82 cusec of water is too little as 1 cusec equals to 28.32 litres of water per second."
"The average flow of the river during the dry season is 794 cusecs, while the annual average flow is around 1,878 cusecs of water. Withdrawal of 1.82 cusec of water is about 0.23 percent of the dry season flow of the Feni river," stated the press release.
