GESTION ET VALORISATION DES EAUX USEES EN ALGERIE

Abstract

Water is a limiting factor in the development of agriculture; scarcity is understood in terms of water stress and irregularity of the resource, two factors likely to increase with climate change. Face the challenge of ensuring the coverage of water needs for agriculture in Algeria , an active political mobilization of water resources has been implemented , as well as new management tools is the reuse of wastewater in agriculture .

 In Algeria, the presence of specific discharge standards for wastewater reuse in agriculture (Executive Decree n ° 93-160 of 10 July 1993 and Executive Decree No. 06-141 of 19 April 2006) and the presence of regulations fixing the modality wastewater reuse and the list of crops and their conditions of irrigation by treated wastewater (Executive Decree No. 07-149 of 20 May 2007 and the ministerial decree of 2 January 2012) is a promotion of projects reuse of treated wastewater.

Leaders, public and private, have to make decisions on wastewater reuse in agriculture. They are faced with the need to exploit increasing amounts to meet ever greater demands. Integrated management of treated wastewater inAlgeria, now institutionally recognized as a model of public- private partnership is the best approach to development and an effective and sustainable management of treated wastewater in the face of increasing water demands.
