"If we can reverse these drains and make these flow into Balu River and Begunbari Khal the contamination may be stopped," said Dhaka Transport Coordination Board (DTCB) Executive Driector Quamrul Islam Siddiqui.

The meeting also observed that due to indiscriminate encroachment of the lake, the drains could not be diverted to other water bodies. "Once the walkway is complete then it will be possible to divert the flow of the drains to Balu River and Begunbari khal,"

Recently, the Daily Star reported about the dead fishes in the lake owing to heavy toxic water.

Rajuk Chairman Iqbaluddin Chowdhury, Dhaka City Corporation (DCC) Chief Executive Officer Solaiman Chowdury, Dhaka Water and Sewerage Authority (WASA) Managing Director Ataur Rahman and others were present in the meeting.

It is learnt that the cost of relocation of the drains in Gulshan might come from the Road Improvement Fund of the DCC and Rajuk.

Dhanmondi Lake used to be contaminated by the drains and sewerage lines earlier. "The lake improvement and diverting the drains of Dhanmondi area have made it possible to reduce the level of pollution," said Siddiqui.

"If there is any contamination in Dhanmondi lake it is because of external reasons," added Siddiqui.

The meeting also discussed about the construction of two new link roads in the city to reduce traffic jam. "We have discussed the proposed link road from Bijoy Sarani to Tongi Diversion Road," said Siddiqui.

"The meeting also discussed about the construction of the proposed Rampura-Hatirjheel Road. We have stressed to have adequate space for drains on bodies side of the proposed road so that the water of the city can be discharged," said Siddiqui.
