NDMU CPE-CES Office Collaborates with Interfacing Development Interventions for Sustainability (IDIS) in Hosting Rainwater Harvesting Forum Advancing Sustainable Water Solutions in Koronadal City

Notre Dame of Marbel University (NDMU) hosted the Rainwater Harvesting Forum on February 27, 2025, gathering environmental experts and stakeholders to promote sustainable water conservation in the City of Koronadal.

The forum emphasized rainwater harvesting as an environmentally responsible and socially acceptable practice. Defined as the collection and storage of rainwater from rooftops for future use, the system offers a clean and cost-free water source suitable for irrigation, cleaning, and other household needs.

Speakers highlighted its long-standing relevance, rooted in both traditional practices and modern sustainability efforts. In his message, Sir Melvin Apenton reaffirmed that Notre Dame of Marbel University continues to live out its moral responsibility toward sustainable development by promoting environmental awareness and action.

Environmental Research Specialist EnP. Lemuel I. Manalo discussed the importance of rainwater harvesting for Koronadal, citing validation efforts since 2018 to monitor environmental sustainability initiatives and compliance. He underscored the need for data-driven implementation, including assessing system efficiency and water quality.

The forum also outlined the key components of rainwater harvesting systems: catchment, conveyance, treatment, storage, and drainage. Data shared during the session revealed limited adoption, with studies showing low operational rates and awareness among establishments.

During the open forum, Engr. Villanueva of the Philippine Institute of Civil Engineers–Koronadal Chapter urged a gradual rollout, suggesting government facilities lead implementation to set an example. Atty. Arjay Sustiguer, meanwhile, emphasized the need to address affordability and feasibility concerns, noting that costs and accessibility must be considered to ensure fair adoption.

The forum concluded with a call for stronger collaboration among government, academe, and communities to advance sustainable water management and build environmentally resilient cities.
