The first objective of the project is to contribute to access to essential drinking water services for these populations through the rational use of natural water resources. The first pilot site is located in the village of Urisa, located at the gates of the biodiversity reserve of the Kaimana region and a partner of the Lengguru scientific project. Located upstream of Arguni Bay, the village of Urisa has nearly 270 inhabitants. Each family feeds on rainwater and lights up with a generator for a few hours a day if their income allows them.

The EDEN’R project consists of setting up the infrastructure that will provide drinking water to the inhabitants of Urisa village from a natural water source identified 8km upstream. Capturing, pumping and routing water will require electrical energy to power pumps. Since the village does not benefit from electricity, this energy would be supplied by photovoltaic panels.

In order to ensure the sustainability of the facilities, a training component is essential. The aim will then be to provide the necessary organizational and technical foundations to make this pilot project a sustainable project, reproducible on other villages and carried by local actors independently.

Experts-Solidaires and the HAMAP Humanitarian association are collaborating on the implementation of this project.
