SUPRA and Nagaoka International Corporation Japan Cooperate to Advance Water and Energy Technologies in Indonesia
PT Supra Internasional Indonesia and Nagaoka International Corporation have entered into a strategic cooperation focused on reshaping the infrastructure landscape in Southeast Asia, particularly in the domains of water treatment, intake technology, and energy systems. While the partnership itself reflects an alignment of operational strengths, what it truly represents is a mutual response to a deeper structural question: How can water and energy, two finite and interlinked resources, be secured, managed, and scaled in a region defined by fragmentation, volatility, and accelerating demand?
At the center of this cooperation is a shared commitment to engineering relevance over redundancy. SUPRA’s role as an integrator across infrastructure lifecycles, ranging from feasibility and permitting to design implementation and local operation, meets Nagaoka’s deep bench of proprietary solutions: specifically, CHEMILES, a low-energy, chemical-free water treatment system; Nagaoka Screen, a globally recognized intake screen that allows for high-efficiency water capture with minimal ecological disruption; and HiSIS, a seawater intake technology adapted for saline environments with heightened biofouling and suspended solids.
The choice of technologies is deliberate. CHEMILES (Chemical-less Ion Exchange System) is emblematic of a new generation of water treatment that forgoes high reagent dependency, minimizes operational carbon footprints, and delivers sustainable throughput for municipalities and industrial users alike. It reflects a broader shift, from large, chemically intensive central plants to decentralized, low-impact systems that can operate in resource-constrained geographies.
Likewise, Nagaoka Screen is not simply a product but a design philosophy: engineered to preserve aquatic ecosystems while ensuring high-intake efficiency and mechanical durability in diverse environments. In riverine, coastal, and inland settings where intake infrastructure has historically caused ecological strain, Nagaoka’s solution offers a path forward, balancing extraction efficiency with regulatory compliance and biodiversity considerations.
Beyond water, Nagaoka's experience in Screen Internals for oil refining and petrochemical complexes, deployed in more than 65 countries, is equally material to the region’s energy transition. As Southeast Asia grapples with the dual challenge of decarbonizing legacy infrastructure while maintaining energy access, the value of adaptive, modular internals for retrofitting and new builds has become clear.
For SUPRA, the strategic rationale is multidimensional. First, the technologies Nagaoka brings are deployable at scale, but flexible enough for emerging markets where environmental regulations and cost structures can vary widely. Second, these technologies are increasingly sought after in ASEAN economies seeking to de-risk infrastructure development under ESG scrutiny and blended finance mechanisms. Third, Nagaoka’s solutions align with SUPRA’s regional delivery mode, localized execution, lifecycle accountability, and modular integration.
Rather than positioning this cooperation as a single venture or project-specific alignment, both parties view it as an operational platform, a framework from which both public and private sector clients can draw tested, reliable, and sustainable water-energy infrastructure. As climate variability continues to redefine the design envelope for infrastructure assets, this approach allows for agility without sacrificing technical depth.
