Supply will resume at 8pm on Tuesday, according to an official of the state gas transmission and distribution agency Titas.
Homes, businesses, industries and CNG refuelling stations in Monipuripara, Agargaon, Taltola, Shewrapara, Paikpara, West Kazipara, Pirerbag, Shyamoli, Mirpur-10 and nearby areas have been without gas from 8am.
Supply has been suspended as tie-in work is being carried out on a large gas line underneath a new building at the Planning Department after its valve dropped, said Mirza Mahbub Hossain, manager of Titas' PR wing.
The authorities are also working to repair leaks in a few old pipelines in the area, according to Titas Director Rana Akbar Haidari.
The outage has brought untold sufferings to residents of the affected parts of the capital who were not prepared for it.
"I found out after waking up in the morning that I could not light the stove in my kitchen. I didn't hear the announcement regarding the gas shutdown. I hadn't prepared any meals for today," said Soniya Siddiqua, a resident of Shewrapara.
