Waste Water Reuse for Irrigation in Algeria (WAWARIA)

The best way to recover waste water: membrane-filtered water for greenhouse cultivation in Algeria

Waste from domestic sources or industrial processes such as oil and gas production and refinery can be valuable for irrigation. But how much treatment will it need?

The overarching objective of the Waste Water Reuse for Irrigation in Algeria (WAWARIA) project is to demonstrate the potential of using waste water for irrigation when it has been treated and polished with membrane-based filtration.

The project compares traditional ground water, waste water treated using current methods, and waste water that has been passed through a membrane based filtration system. An Eltso NRO Fusion membrane filtration device will first treat waste water produced by the Waste Water Treatment Works of the city of Ouargla and then store it before use.

Test plots growing tomatoes, potatoes and cucumbers are used for the comparison. All three irrigation options use identical Alterra drip irrigation devices.

The project has been able to compare crop growth and the proportions of heavy metals and organic compounds in water, soil and plants.

The project is co-managed by Alterra, the research institute at Wageningen UR for the green living environment and ONA, the Algerian sanitation department.
