Oxfam Lebanon Programme

Background

Oxfam is a global movement of people, working together to end the injustice of poverty. Oxfam has been working in Lebanon since 1993. We provide humanitarian assistance to vulnerable people affected by conflict, and we promote economic justice and good governance, and women’s rights. Oxfam also works with local partners to contribute to the protection and empowerment of marginalized women and men.

Project Objective

Oxfam is supporting the South Lebanon Water Establishment in the rehabilitation of their solar PV water pumping stations. Therefore, Oxfam is seeking a supplier/contractor to replace damaged components of the PV plants used for water pumping in South Lebanon (batteries of lead acid type, PV panels, contactors, electric relays, sinewave filter, reactors, padlocks, valves, etc.)
