InJourney Tourism Development Corporation has implemented seawater desalination technology at The Nusa Dua tourism area in Bali as part of its sustainable tourism development strategy. The initiative uses Sea Water Reverse Osmosis technology to convert seawater into drinking water.
Based on an official statement, the SWRO system is intended to support an environmentally responsible tourism ecosystem. By using seawater as an alternative raw material, the facility reduces dependence on groundwater and conventional freshwater sources in the area.
“The implementation of green utilities such as Sea Water Reverse Osmosis (SWRO), Wastewater Management Plants (WWTP), integrated Waste Management, and Reclaim Water has ensured that tourism activities run efficiently, safely, and while maintaining the carrying capacity of the environment,” said ITDC Director of Operations Troy Warokka, quoted from the official release, Friday (23/1/2026).
Three Months of Operation
The SWRO facility at The Nusa Dua has been operating for the past three months. During this period, it has produced 331,382 cubic meters of clean water. Once operating at full capacity, the system is designed to generate up to 1,314,000 cubic meters of clean water per year.
ITDC stated that the use of desalination technology contributes to strengthening water resilience in the tourism zone. The availability of an alternative water source is expected to reduce risks associated with water scarcity, particularly those linked to climate change.
Supporting Sustainable Tourism Operations
According to ITDC, the application of green initiatives in The Nusa Dua is a core operational foundation aimed at developing the area into a premium tourism destination that is both resilient and sustainable. The SWRO facility is positioned as a key infrastructure component to ensure the continuity of tourism operations while maintaining environmental responsibility.
The company explained that diversifying water sources is essential to reducing pressure on groundwater reserves, which are often vulnerable to overuse in high-demand tourism areas.
Regulatory Milestone
The implementation of the SWRO facility has also resulted in a regulatory achievement. ITDC Nusantara Utilitas, a business entity under ITDC, has become the first company in Indonesia to receive an official permit from the Ministry of Marine Affairs and Fisheries to process seawater into potable water using modern technology.
This permit confirms that the desalination process complies with applicable standards for producing water suitable for consumption.
Official Statement
President Director of ITDC Nusantara Utilitas, Anak Agung Istri Ratna Dewi, said the SWRO facility represents a concrete step toward strengthening water resilience at The Nusa Dua. She added that the initiative supports efforts to reduce pressure on groundwater resources.
“With this safe and scalable technology, we ensure a stable supply of clean water for all tenants and tourists without sacrificing environmental sustainability,” said Anak Agung Istri Ratna Dewi.
She also stated that recognition from the Ministry of Marine Affairs and Fisheries demonstrates that green innovation can be implemented alongside efficiency and high service standards.
