LA REUTILISATION DES EAUX USEES EPUREES A DES FINS AGRICOLES - CAS DE LA STEP DE LA VILLE D’AIN TEMOUCHENT -

Abstract

The reuse of treated wastewater is a voluntary and planned action that aims to produce additional quantities of water for different uses. Today the national strategy for sustainable development in Algeria is particularly materialized through a strategic plan that brings together three dimensions namely: Social, Economic and Environmental. Faced with the challenge of ensuring the coverage of water needs for agriculture in Algeria, the reuse of treated wastewater appears as the most suitable solution for irrigation. The main objective of this work is to know the framework the regulatory framework governing the use of unconventional waters, know the origins, nature, quality and measurement parameters of polluted water. This work will therefore have the intention of describing the characteristics of the Ain Témouchent wastewater treatment plant, its production capacity, the quality of the purified water at the outlet and the possibilities of the reuse of these waters in the field of irrigation. . The results of the analyzes obtained show that these waters can be exploited in localized irrigation for a specific crop group (Citrus, Arboriculture ... etc.), according to the studied methods that have yielded successful results (Sizing).
