DOST chief backs innovative filtration system to reduce water pollution in Dinagat Islands
By Renelle L. Escuadro
BUTUAN CITY (PIA) — Department of Science and Technology (DOST) Secretary Renato U. Solidum Jr. led the ceremonial groundbreaking for the Vertical Helophyte Filtration System (VHFS) at the San Jose municipal slaughterhouse in Barangay Mahayahay, San Jose, Dinagat Islands, introducing an innovative approach to wastewater treatment and environmental protection.
Held on October 9, it also marked the start of the technology’s local adoption under the Promoting Resilient Opportunities for Growth through Smart and Sustainable Communities in the Municipality of San Jose (PROGRESS-San Jose) project under DOST’s Smart and Sustainable Communities Program (SSCP).
The VHFS uses helophytes, or plants adapted to waterlogged conditions, and layers of filtration materials to help treat wastewater. As wastewater passes through the system, the filter media traps the suspended solids, while microorganisms around the plant roots help break down organic pollutants. This natural treatment process aims to improve wastewater quality before discharge and minimize its potential impact on surrounding water resources.
Secretary Solidum emphasized the importance of proper waste management because the Dinagat Islands continues to face challenges related to water scarcity.
“Today, we break ground on a transformative project—one that harnesses technology with nature at its core. Treating wastewater properly is not only an environmental concern but also a practical step toward protecting the limited water resources available to communities. By using wetland plants and layered gravel filters to naturally purify wastewater, the VHFS can help keep San Jose’s waterways and coastal waters cleaner and safer,” he said.
The secretary added that the initiative also advances the Philippines’ commitment to the Sustainable Development Goals by promoting clean water and responsible wastewater management, sustainable communities, responsible use of resources, and the protection of coastal and marine ecosystems.
With a total project cost of P2,297,450, including P1,550,000 in funding from DOST Caraga, the system is expected to support cleaner and more environmentally responsible slaughterhouse operations once operational.
The groundbreaking was also joined by DOST Undersecretary for Regional Operations Sancho A. Mabborang, Assistant Secretary for Countryside Development Maria Teresa B. De Guzman, DOST Caraga Regional Director Noel M. Ajoc, DOST Dinagat Islands Provincial Director Ann O. Tibe, and San Jose Vice Mayor Rechard Pasquil.
With strong support from the local government of San Jose, in partnership with the DOST Dinagat Islands Provincial S&T Center and the DOST Caraga, DOST continues to advance science-based solutions that help the LGU to address environmental challenges and build cleaner, more sustainable, and resilient communities.
