Solar Desalination OSMOSUN for Indonesia


Solar Desalination OSMOSUN for Indonesia

GTI Awards 2020 – Water

General information:

Island (Region, Province, Country):

Papagarang, komodo national park, INDONESIA


Budget / cost of the project:


Project objectives:

The water supply of the remote islands in the komodo national park, is made through water tank coming from the mainland at high cost and complicated logistic.  The objective of this pilot project was to supply affordable and sustainable water to the inhabitants of the islands.


Project description of activities and specific interventions:

This first solar desalination installation without battery in the island of Papagrang allows a better access to drinking water at more affordable price. Designed and implemented by Akuo and Mascara, integrated locally, the installation is now operated by the community. Currently producing drinking water, the system could also provide fresh water and ice to answer the needs of the population.

Public outreach, education and awareness efforts and results:

This first fully replicable pilot project in Indonesia providing drinking water to 500 inhabitants of the island of Papagarang leads the way to scale up this innovative and sustainable technology for the water supply in the country.

We believe solar desalination without battery is an effective solution to provide water and ice to the numerous remote communities of Indonesia and is a sustainable and affordable alternative  to the current water tank transport.

This project was implemented by Akuo Energy, Komodo Water and Mascara Renewable Water. An important awareness campaing was made on hygiene and sanitation and local as well international press has relayed the communication.


Economic value added and how calculated:

Before the project, water cam through water tank transported by ships to the island. After the project, the price of water was divided by 3 allowing the local population to benefit sustainable and affordable water with simplified logistic.


Ecological and social project outcomes:

The solar desalination OSMOSUN replace the supply by ships. As a result, we have dramatically reduced CO2 emission by replacing ship transport supplied by diesel by solar powered unit. In addition, we use local resources (sun and water) and local manpower to operate the system instead of water coming from thousands of kilometer away and produced and transported with conventional energy.
