Island nations such as the Seychelles and the Maldives face unique challenges when it comes to securing reliable access to drinking water. With no natural freshwater resources of sufficient scale, all public water supply must be based on seawater desalination.
In the Seychelles, the Public Utilities Corporation operates four waterworks supplying drinking water to more than 80,000 residents and up to 200,000 visitors. Similarly, in the Maldives, the Malé Water & Sewerage Company is responsible for delivering clean and safe drinking water to approximately 100,000 inhabitants of the capital city, Malé, as well as large numbers of tourists. In both locations, growing demand, limited natural resources and the need for sustainable, resilient infrastructure place high demands on water treatment solutions.
BWT has designed and installed advanced seawater desalination systems for all public waterworks in the Seychelles. The systems are engineered to operate reliably under island conditions, ensuring continuous production of high-quality drinking water.
In the Maldives, BWT desalination systems are an integral part of the water supply infrastructure operated by the Malé Water & Sewerage Company. The solutions are designed to combine high operational reliability with efficient energy and water use, supporting the utility’s ambition to provide a modern and sustainable water supply.
Across the four waterworks in the Seychelles, the combined BWT desalination systems produce a total of 13,000 m³ of clean drinking water per day, ensuring a stable and secure water supply for both residents and visitors.
In the Maldives, BWT systems produce approximately 11,000 m³ of clean drinking water every day, supporting daily life in the capital city and meeting the needs of the tourism sector.
Together, these projects demonstrate how advanced desalination technologies can secure sustainable drinking water supplies in regions fully dependent on seawater as their primary water source.
