Waste oil, fat, and grease directly discarded into sewers in Ho Chi Minh City is tormenting local drainage workers who are tasked with working amongst the foul smells and blockages caused by such wastes.
Drainage workers said they were tired of fat, oil, and grease building up in sewers.
Though some parts of the city have begun using machines to clean sewers, there are still some areas where the job must be done manually.
In certain places, workers must travel deep into the sewers and use crowbars to remove the build-up of waste oil, fat, and grease, according to Le Van Hay, a local drainage worker.

A report by the Ho Chi Minh City Infrastructure Management Center under the municipal Department of Construction showed that waste fat, oil, and grease deposits in sewers hinder the flow of wastewater, increase the risk of flooding when it rains, and cause unpleasant smells.
The Department of Construction has tasked related authorities to supervise restaurants’ wastewater discharge.
The city has also installed new manhole covers to improve the water flows, prevent garbage from drifting into sewers, and reduce foul odors.
