Project i-Float Gains Global Recognition for Flood Resilience Innovation
Manila Water’s Project i-Float has earned international acclaim for its effective flood resilience innovation. This project highlights practical engineering solutions that help tackle urban flooding challenges in Metro Manila.
Showcased at the 41st International Association for Hydro-Environment Engineering and Research (IAHR) World Congress and the Singapore International Water Week (SIWW) Spotlight 2025, Project i-Float demonstrates how simple, innovative tools can significantly protect communities from flood risks.
Simple Innovation with Big Impact
The initiative was presented by Riza Oiga, head of the Wastewater Facilities Operations Department, and developed alongside Christian Quintos and Marvin Jambre. It has strong backing from Manila Water due to its potential to enhance flood resilience across the capital region.
Project i-Float employs floating bar screens installed in waterways such as Balante Creek in Marikina City. These screens trap solid waste, preventing blockages that typically cause water to overflow, thereby reducing flood occurrences.
Since its launch, the project has protected over 180,000 residents from seasonal floods. It has also improved the Marikina North Sewage Treatment Plant’s efficiency by allowing better water flow and treatment.
Effective Waste Management During Pilot Phase
During the pilot phase, the floating screens collected approximately 24 cubic meters of solid waste each month. This waste removal contributed to a noticeable decrease in flooding between August and November 2024.
The project supports community goals aligned with Angat Buhay, an NGO dedicated to disaster preparedness and empowerment. Through its Women Champions in the Water Sector Program, Angat Buhay helped present Project i-Float at the IAHR World Congress, celebrating it as a prime example of grassroots innovation and teamwork.
“Project i-Float proves that innovation doesn’t always mean complexity. With the right partnerships and practical tools, we can build safer, more resilient communities,” Oiga said.
Expanding Flood Resilience Across Metro Manila
Manila Water plans to extend Project i-Float to other flood-prone areas, including Pasig, Taguig, and Navotas. Supported by the Manila Water Foundation and local government units, the next phase will introduce modular designs and affordable materials customized for diverse urban environments.
This expansion aims to strengthen flood defenses and improve water management throughout Metro Manila, enhancing community safety and sustainability.
