Fresh water is becoming a strategic issue for tourism destinations. At The Nusa Dua in Bali, a new solution is already taking shape with the presence of SWRO. Seawater is now being processed into clean, consumable water through Sea Water Reverse Osmosis technology. It marks a major step toward long term water security in the area.
The technology is operated by InJourney Tourism Development Corporation, or ITDC. Its purpose is clear. The system supports a sustainable tourism ecosystem built on environmental responsibility. Water management is treated not as a supporting function, but as a core operational priority.
“The implementation of green utilities such as Sea Water Reverse Osmosis or SWRO in Nusa Dua, Wastewater Treatment Plants (WWTP), integrated waste management, and reclaimed water has ensured that tourism activities run efficiently and safely while maintaining environmental carrying capacity,” said ITDC Operations Director Troy Warokka, as quoted from the official statement on Friday (23/1/2026).
According to Troy, these green initiatives form the operational backbone of the destination. They are designed to ensure that The Nusa Dua continues to function as a premium tourism area that is both resilient and sustainable.
“For ITDC, sustainability is not just an agenda, but the operational foundation of the area to ensure that The Nusa Dua remains a resilient and sustainable premium destination for future generations,” he added.
The SWRO facility itself is no longer in the planning phase. It has been operating at The Nusa Dua for the past three months. During that period, the system has produced 331,382 cubic meters of clean water. When operating at full capacity, annual production is expected to reach 1,314,000 cubic meters.

By using seawater as an alternative water source, the facility significantly reduces reliance on groundwater and limited freshwater supplies. This shift plays an important role in strengthening water resilience across the area.
The technology also helps mitigate the risk of water shortages driven by climate change. At the same time, it ensures the continuity of tourism operations at The Nusa Dua, even under increasingly uncertain environmental conditions.
The adoption of SWRO is described as a concrete step to reinforce regional water security. It also contributes to reducing pressure on underground water resources, which are increasingly vulnerable.
“With this safe and measurable technology, we ensure a stable supply of clean water for all tenants and tourists without compromising environmental sustainability.”
