Cebu — The cities of Mandaue and Lapu-Lapu are taking a major leap toward environmental sustainability by pursuing collaborative partnerships with a delegation from Yokohama, Japan. During high-level meetings held in late June 2026, local officials explored the adoption of advanced Japanese wastewater treatment technologies and sewerage management expertise. By integrating Yokohama’s proven infrastructure strategies into their urban development agendas, both cities aim to address long-standing sanitation gaps and protect the vital water channels that surround the Mactan area. This initiative marks a significant step in transforming how Metro Cebu manages its environmental footprint through international cooperation and shared technical innovation.
Pioneering Sustainable Infrastructure
In Mandaue City, Mayor Thadeo Jovito "Jonkie" Ouano welcomed the Japanese delegation, led by Shimizu Koji, the Director for Sewage Works Management of Yokohama City. The discussions centered on the development of a proposed wastewater treatment facility, with the Japanese team offering to provide detailed proposals and technical guidance on the construction and operation of the plant. This partnership builds upon the established sister-city relationship between Mandaue and Yokohama, which has long fostered cooperation on development and climate-resilience projects. By leveraging Yokohama’s extensive experience in urban waterworks, Mandaue City intends to ensure that its future wastewater infrastructure is not only efficient but also compliant with international environmental standards.
Building a Cleaner Metro Cebu
Meanwhile, Lapu-Lapu City Mayor Ma. Cynthia "Cindi" King-Chan explored similar collaborative opportunities, focusing on the broader goal of long-term environmental protection. The exchange of ideas highlighted innovative solutions—including technologies from global industry leaders like Toshiba—that could be utilized to improve sewerage management across the city. This move aligns with the larger "Master Plan Study on Comprehensive Sewerage System Development of Metro Cebu," a multi-year project involving the national government, JICA, and local water districts. As both cities work to modernize their sanitation systems, these partnerships reflect a proactive commitment to curbing pollution and ensuring that Metro Cebu’s rapid urbanization does not come at the expense of its fragile coastal and river ecosystems.
