The $211-million Kaliwa Dam project in the Philippines has sparked significant concern as it poses the potential to submerge half of the homes in a village located in the Sierra Madre mountain range. Designed to address the growing water supply needs of Metro Manila and its surrounding areas, the dam has been met with fierce opposition from environmental advocates, indigenous communities, and local residents who fear its devastating social and ecological consequences.

The Kaliwa Dam, part of the New Centennial Water Source Project, is expected to provide up to 600 million liters of water per day to Metro Manila, easing the region’s persistent water shortages. However, the construction of the dam would involve flooding portions of the Sierra Madre, one of the country’s most biodiverse and environmentally critical regions. This includes the displacement of local communities, many of whom belong to the indigenous Dumagat-Remontado people who have lived in harmony with the area’s natural environment for generations.

In one of the villages most at risk, nearly half of the homes are projected to be submerged once the dam’s reservoir is filled. Residents face the prospect of losing not only their homes but also their farmlands, livelihoods, and cultural heritage. Despite government assurances of relocation and compensation packages, affected families remain skeptical, citing inadequate consultations and a lack of clear plans for resettlement.

Environmentalists warn that the project could have far-reaching impacts on the Sierra Madre’s ecosystems. The mountain range, often referred to as the “backbone” of Luzon, serves as a critical natural barrier against typhoons and a habitat for numerous endangered species. The dam’s construction would result in deforestation, habitat destruction, and disruptions to the natural water flow, further exacerbating the region’s vulnerability to climate change and natural disasters.

Proponents of the Kaliwa Dam argue that it is a necessary infrastructure project to secure the water supply for Metro Manila’s rapidly growing population. They emphasize the importance of balancing development with environmental preservation and have promised to implement mitigation measures to minimize the project’s negative impacts. However, critics believe that alternative solutions, such as rehabilitating existing water systems and exploring more sustainable sources, should be prioritized over large-scale projects like the Kaliwa Dam.

As the controversy surrounding the dam continues to grow, calls for greater transparency, inclusive dialogue, and consideration of alternative options have intensified. The fate of the Sierra Madre village and its residents now stands at the heart of a broader debate on the balance between development and environmental stewardship in the Philippines.
