A new reverse osmosis facility is now converting seawater into potable water, marking a significant step toward water resilience and sustainable tourism in one of Bali’s premier destinations.
NUSA DUA, Bali — In a landmark move for sustainable tourism infrastructure, the management of The Nusa Dua resort area has fully operationalized a large-scale seawater desalination plant, transforming ocean water into a reliable source of clean drinking water for the precinct.
The Sea Water Reverse Osmosis (SWRO) facility, managed by ITDC Nusantara Utilitas under the InJourney Tourism Development Corporation (ITDC), has been active for the past three months. It represents a strategic shift to reduce the premium tourism enclave’s dependence on Bali’s strained groundwater and freshwater sources.
“Green utilities like Sea Water Reverse Osmosis ensure that tourism activities run efficiently and safely while maintaining environmental sustainability,” said Troy Warokka, ITDC’s Operations Director, in an official statement on Friday, January 23, 2026. “For ITDC, sustainability is not just an agenda; it is the operational foundation to ensure The Nusa Dua remains a resilient and sustainable premium destination for future generations.”
Capacity and Impact
The plant has already produced 331,382 cubic meters of fresh water. At full capacity, it is designed to generate up to 1,314,000 cubic meters annually. This output is intended to provide a stable, climate-resilient water supply for the resort’s hotels, facilities, and visitors, mitigating risks associated with water scarcity.
The project has also garnered formal recognition, with ITDC Nusantara Utilitas becoming the first company in Indonesia to receive an official license from the Ministry of Maritime Affairs and Fisheries (KKP) to process seawater into potable water using modern technology.
A Broader Sustainability Framework
The SWRO plant is part of a integrated “green utility” ecosystem in Nusa Dua, which also includes a centralized wastewater treatment plant, a comprehensive waste management system, and a water reclamation program.
“With this safe and measurable technology, we ensure a stable supply of clean water for all tenants and tourists without compromising environmental sustainability,” said Anak Agung Istri Ratna Dewi, President Director of ITDC Nusantara Utilitas.
The initiative underscores a growing commitment within Bali’s tourism sector to adopt long-term solutions for resource management, positioning Nusa Dua as a leader in operational resilience amid global environmental challenges.
