One of Asia’s Fastest-Growing Cities Just Got a $1 Billion Plumbing Bill

Suffering continues as development trumps pollution control in Phnom Penh, Japan wants to help fix it.

Next City

As new development overwhelms Phnom Penh’s aging wastewater management system, the Cambodian capital seeks an ambitious remake.

It was a scene that perfectly encapsulated Phnom Penh’s development dilemma: Hundreds of ramshackle houseboats that usually anchor in the river north of the Cambodian capital had pushed downstream in search of cleaner waters, mooring with a view of glittering high-rise buildings that are reshaping the city skyline.

Home to poor fish farmers who earn their living on the water, the boats had found refuge from a river sludge in the shadow of a city that’s in the throes of rapid and continually accelerating development — with little regard for the negative consequences borne largely by the poorest residents. As they waited for the sludge to clear, local officials denied that sewage overflow had caused a fish die-off. They instead blamed, variously, climate change causing the water to become too hot and heavy rain, claims unconvincing to residents.

“The sewage water made the fish die,” said 49-year-old Ming Tiv Bo, pointing to a blue container floating near her houseboat in May. “All the fish inside the barrels, all the fish died.”

Bo and other fish farmers had experienced the sludge before. Ly Chhun Leng lives next to a blackened canal upriver from where the fish deaths occurred. She says the amount of sewage pumped into the slow-moving water led her community to give up fishing altogether. “It always happens, every year,” she says.

But mass fish die-offs of the scale this past spring are unusual — and a frightening preview of the future to come if Phnom Penh continues to grow without remaking its 60-year-old water management system amid spiraling population growth.

“It’s a very critical situation now,” says Nishikawa Masashi, a project adviser at the Japan International Cooperation Agency (JICA), the Japanese government’s international aid and development agency and the lead force behind a new $1 billion proposal to adapt Cambodia’s wastewater management system to meet the dual challenges of rapid urbanization and climate change.
