Mediterranean water resources are extremely under stress, especially in the south and east shore. In Jordan, Lebanon and Tunisia, water demand constantly increases, while water use efficiency can still be considered as limited. These are the two most critical factors regarding the sustainability of the most elementary earth resource: water. Under this concept, policies aiming at improving usage efficiency and at reduced losses and poor usage, are urgently needed. In this sense, AQUAKNIGHT project focuses on optimizing consumption and minimizing the Non-Revenue Water (water not metered or billed to consumers) through the implementation of five pilot projects in the cities of Limassol (Cyprus), Genoa (Italy), Alexandria (Egypt), Tunis (Tunisia) and Aqaba (Jordan).
