Solar-Powered Rainwater Harvesting System: A Proposal for Emergency Water Solutions in Malaysia

In Malaysia, frequently droughts had causes to disruption of municipal water supplies which leaving the communities with the insufficient access of clean and potable water. Previously, Malaysia traditional rainwater harvesting system, designed significantly for non-potable uses failing to meet the need of safe drinking water during emergency. This project critically proposes an innovation of solar-power rainwater harvesting system that inspired from roof harvested rainwater in Australia. The Australian technology with renewable energy integration works to provide potable water during drought and municipal water disruptions. The methodology uses to develop the system includes rooftop catchments, multi-stage filtration, UV sterilization, and solar-powered pumps. The systematic approach of zoning system metering enables smart water distribution with controlled usage. The innovation of system promoting environmental sustainability aligns with Environmental, Social and Governance (ESG) principles, ensuring equitable access of clean water for communities, and fostering collaborative governance through partnership with stakeholders. The system encourages sustainable water management, contributing to environmental and impactful solution for water security challenges in Malaysia.
