Abstract

In 2022, the Philippines experienced severe tropical cyclones that caused significant agricultural damage, impacting over 46,000 farmers. Despite government aid, long-term floodwater management remained unaddressed. This study explores the potential of floodwater recycling systems, particularly the Agricultural Water Infiltration Tank (AWIT), to improve agricultural resilience and sustainability. Using a Randomized Complete Block Design (RCBD), the study assesses AWIT's effectiveness as a flood-suction device. The AWIT incorporates multi-stage filtration, including granular filtration, chemical treatment, sedimentation, reverse osmosis, and UV light disinfection.

Results demonstrate that AWIT effectively removes contaminants, improving water quality for agricultural use. The system provides a sustainable water source, reducing water procurement costs and supporting farmers during droughts. Recommendations include further field testing, optimization of chemical dosing, and integration of automation for real-time monitoring. With government support, AWIT has the potential to be a scalable solution for floodwater management and agricultural water sustainability.
