There’s water under there. Black and malodorous.
The canal’s flow is heading, slowly, for a sewage treatment station.
Above is the beginning of Boueng Trabek market. It’s always busy. When finished eating and drinking the stall-holders and their customers heave their rubbish in.
It stinks, and when the rains arrive it overflows. Partly because of the the volume of water, but also because the trash blocks the flow.
It’s been this way for years.
