SARIAYA, Quezon - Harnessing the power of the sun to nourish the land, a new era of sustainable agriculture dawned today, April 30, 2025 in Sariaya, Quezon, with the inauguration of a state-of-the-art Solar-Powered Irrigation System. The National Irrigation Administration (NIA) officially turned over the vital infrastructure in a move expected to significantly uplift the livelihoods of local farmers. The project was lauded as a significant step towards energy independence in the agricultural sector.

Speaking at the inauguration of the ₱50-million Castañas Centro Communal Irrigation System (CIS) in Barangay Castañas, Sariaya, Quezon, Speaker Ferdinand Martin G. Romualdez reaffirmed Congress's commitment to expand access to modern, sustainable irrigation systems for Filipino farmers, emphasizing the life-changing impact of solar-powered pump irrigation projects (SPIPs) on rural communities.



"Narito tayo para magbukas ng mas malaking oportunidad para sa ating mga magsasaka at sa buong komunidad ng Sariaya," Speaker Romualdez declared. "Simple ang layunin: siguraduhin na ang bawat tanim, bawat ani, at bawat pangarap ng ating mga magsasaka ay hindi mauubos dahil sa kakulangan ng tubig."

He pointed out that instead of spending up to ₱80,000 per cropping season on diesel, the irrigation is now solar-powered—more affordable, reliable, and environmentally friendly. Speaker Romualdez stressed that grassroots-centered projects like SPIPs are a clear priority for Congress, asserting, “This is the kind of project Congress prioritizes: Practical. Directly benefiting the people. Not just on paper.”

He was joined by NIA Administrator Eduardo Eddie G. Guillen and NIA Calabarzon Regional Manager Engr. Roberto P. Dela Cruz, signifying the regional focus on agricultural development. Deputy Speaker, 2nd District Representative David "Jayjay" Suarez, Sariaya Mayor Marcelo Gayeta, Tiaong Mayor Arjay Mea, and other local government officials enthusiastically participated in the event, underscoring the strong collaboration between national and local entities. Representatives from the Irrigators Association were also present, expressing their gratitude for the project.

Representatives from other government offices also attended, demonstrating a unified approach to supporting the agricultural sector. NIA Administrator Guillen praised the House’s efforts, observing that SPIPs are faster and cheaper to deploy compared to traditional irrigation systems. He mentioned that NIA completed a significant number of SPIPs in 2024 and is on track to accomplish another substantial number this year, projecting substantial long-term environmental benefits from these solar-powered systems.

Administrator Guillen explained, "Eliminating the reliance on diesel, the project is projected to save each farmer up to ₱80,000 per cropping season. This significant reduction in operational expenses will free up valuable capital for farmers to invest in essential farm inputs such as fertilizers and high-quality seeds, potentially leading to higher yields and better quality produce. These savings offer a crucial financial buffer, allowing families to allocate resources to education, healthcare, and other household needs, thus improving their overall quality of life."

This financial relief is particularly significant for the 33 farmer-families who are direct beneficiaries of this initial phase of the solar-powered irrigation project, irrigating 50 hectares of land. The NIA aims to replicate this successful model in other farming communities across the Calabarzon region and eventually nationwide, contributing to a more resilient and sustainable agricultural sector in the Philippines. The agency is also exploring partnerships with local cooperatives to ensure the proper maintenance and operation of these systems.

Later, he added, "Beyond cost reduction, the initiative promises a more reliable water supply, a critical factor in mitigating the adverse effects of climate change on agricultural yields. The consistent availability of water, powered by a clean and renewable energy source, will enable farmers to plan their planting schedules with greater certainty, reduce the risk of crop failure due to drought, and potentially explore opportunities for multiple cropping cycles throughout the year, further enhancing their productivity and income."

Speaker Romualdez affirmed the national government's commitment to agricultural advancement and farmer support, aligning with President Ferdinand R. Marcos Jr.'s prioritization of food security. He also pointed out that Congress significantly increased NIA’s budget over the past two years, demonstrating the legislative body's dedication to modernizing the agricultural sector. 

The inauguration of this solar-powered system in Sariaya underscores the growing adoption of renewable energy solutions in Philippine agriculture, serving as a model for other regions. The newly operational system is set to benefit Sariaya, Quezon, ensuring a more secure and prosperous future powered by the sun. Local farmers expressed optimism about the increased efficiency and reduced costs associated with the new system.
