Koh Phi Phi, once an ecological paradise, now faces environmental degradation from tourism-driven wastewater pollution. In response, the Phang Nga Wastewater Management Authority expanded with underground tanks—typically topped with unused lawns. This project transforms a 7,072 sqm site into an ecological park integrating wastewater treatment, biodiversity, and community space.
Treated water flows into a phytoremediation pond that polishes it before discharge, while serving as a stormwater basin and irrigation reservoir. Native plants support biodiversity and reduce maintenance. Hardscapes are limited to circulation.
Community participation shaped the design—walking trails, a sports court, bouldering walls, and an outdoor gym provide multi-generational uses.
A living classroom, raising awareness of water purification and biodiversity. Educational features include a water-spinning bike, interactive signage, and access to the treatment process. A water tank is transformed into the “Swimming Fish Tower,” clad in recycled bottle-cap fish tiles, offering views and identity.
This project is a replicable model of how infrastructure can restore ecology, educate, and connect communities.
