6 New OSMOSUN Installations Deployed in Vanuatu

In 2024, OSMOSUN commissioned six new OSMOSUN 0.2 SW units in the Republic of Vanuatu. Nearly 3,000 inhabitants across four islands will now have consistent and sustainable access to fresh, potable, low-carbon water. Located in the heart of the South Pacific, the Republic of Vanuatu is an archipelago state of 83 islands, most of volcanic origin.

Water insecurity is exacerbated by increasingly unpredictable rainfall patterns due to climate change. Traditional freshwater resources, such as rainwater collection and wells, no longer reliably ensure access to drinking water year-round.

In the past, desalination units were installed; however, these, powered by diesel generators, have proven unsatisfactory from an environmental perspective and are highly energy-intensive, with prohibitive costs for the community. During presentations on OSMOSUN’s solutions to water stress issues in the Pacific region, Vanuatu’s water department was impressed by the deployment flexibility, autonomy, and significantly reduced environmental impact of OSMOSUN’s reverse osmosis desalination solutions.

Four OSMOSUN 0.2 SW units connected to solar panels were thus installed on four islands selected by Vanuatu’s Water Department due to the urgency of the situation: Wala, Rano, Vao, and Atchin. The units now supply water kiosks and produce 1.5 m³/day. Two additional mobile units have also been made available for quick deployment to address temporary needs or emergencies. The community’s technical services, assisted by Vanuatu’s national water agency and trained by OSMOSUN during commissioning, will handle the units’ management and maintenance. Recurring visits from OSMOSUN experts are planned to provide ongoing support, thus facilitating local ownership of the equipment.
