Cambodia / The startup aiming to turn the tide on Phnom Penh’s flood issues

The streets of Phnom Penh are often wracked by floods, causing costly damage to roads and other infrastructure. Now, local startup Cambodia Green Infrastructure has a vision to change that. Co-founder Aaron Sexton speaks with Southeast Asia Globe about the organisation’s proposed system, which was among four of nearly 350 development concepts recognised in Seoul last month with a $5,000 award from the Global Green Growth Initiative director-general and former UN secretary general Ban Ki-Moon

Tell us a bit about Cambodia Green Infrastructure and what drew your interest towards problem-solving drainage in the country… 
Phnom Penh is located at the confluence of the Tonle Sap, Mekong and Bassac rivers. The outskirts of the city are made up of wetlands and low-lying areas, and elevation across the city barely rises more than 10m. Much of the city has been developed on the alluvium deposits of previous flood events. Such topographical and hydrological features, combined with monsoonal weather patterns, result in Phnom Penh repeatedly suffering from storm water and flooding issues. Increasing population, urbanisation and rapid development continues to place strain and pressure on the city’s infrastructure, which is already considered to be working at capacity…. Flooding incidents cost the economy an estimated $6 million each month.

Flooding and storm water incidence are predicted to increase in urban areas across Cambodia unless action is taken. Cambodia Green Infrastructure [CGI] was developed out of a frustration of the impacts of flooding and storm water that continue to impact the city of Phnom Penh. CGI’s initial focus is to design and install bioretention systems in urban areas across Cambodia as a retrofit solution to this issue.
