There is an extensive bibliography that analyses the structure of a desalination project from the perspective of chemical engineering, but there is another “engineering” that has been much less studied, which is just as decisive for the plant to be able to operate. The aim of this work is to analyse the economic and legal factors that condition the proper operation of a project and, to this end, we will place special emphasis on the usual agents and contractual agreements. We intend to arrive at a general model of operation that we will construct from the study of three particular cases: Algeria, Tunisia and Egypt. These three countries represent different ways of structuring a project, with the involvement of the public sector being the main element that varies between them.

有大量参考书目从化学工程的角度分析了海水淡化项目的结构，但还有另一种研究较少的“工程”，它对于工厂能否运营同样具有决定性意义。这项工作的目的是分析影响项目正常运行的经济和法律因素，为此，我们将特别强调通常的代理和合同协议。我们打算通过对阿尔及利亚、突尼斯和埃及这三个特定案例的研究来构建一个通用的操作模型。这三个国家代表了构建项目的不同方式，公共部门的参与是它们之间不同的主要因素。
