Ongoing

Phnom Penh's natural lakes and wetlands serve as an unintentional bio-filter for the city's sewage, effectively treating waste water before it enters the Tonle Bassac river. This system, while not formally designed, utilizes the nutrient-rich waste to support aquatic vegetable farming, which in turn enhances the treatment process.
