10 Million Liters of Freshwater Produced by the OSMOSUN Desalination Unit at Lake Goubet in Djibouti

OSMOSUN and its partner IWS (Impact Water Solutions), an integrator and developer of water access solutions, have produced 10 million liters of freshwater with their seawater desalination unit installed near Lake Goubet, Djibouti.

An arid country located on the western coast of the southern outlet of the Red Sea, Djibouti has long suffered from a significant freshwater deficit, making it dependent on its neighbors. The construction of a desalination plant in Doraleh for the capital provided a partial solution, but many communities, often rural and isolated, continue to experience both water scarcity and energy insecurity.

In this context, the African developer Impact Water Solutions (IWS) targeted the communities around Lake Goubet to set up a mini-network for potable water distribution, powered by an autonomous desalination unit. A long-standing partner of Osmosun with several installations jointly deployed and operating for several years, IWS developed, financed, and installed this high social-impact, low-carbon, fully autonomous project. The project supplies more than a thousand people with drinking water through an OSMOSUN 7 SW installation powered by a 40 kW peak photovoltaic plant, with no batteries or connection to the electrical grid. The installation includes two 40 m³ tanks and 7 km of pipelines, managed by an intelligent system that optimizes energy input and freshwater distribution to water kiosks.

Since its commissioning in the summer of 2023, the installation has produced 10 million liters of decarbonized freshwater with a minimal environmental impact. The use of solar panels without batteries for the production and distribution of drinking water avoids the emission of nearly 45 tons of CO₂ annually. The investment and financial structure for this project, developed by IWS and its partners, with a 20-year contract, enable free water access for local populations. The operation of this facility has created 17 jobs, of which 3 are permanent skilled positions.
