However, people come to realize that water is not a limitless wealth of nature. Not only it is a limited resource, but also it is important for people to plan how to use it , as well as the development and exploration of it (ibid).

Water reuse has been recorded as undoubted progress in the Mediterranean area recently (Hidalgo et al, 2004). Some current examples can be pointed out in some Mediterranean countries, which show the considerable benefits of wastewater reuse.

An interesting case in Cyprus is the Larnaca wastewater reuse system. In the year of 2000, the wastewater is being used for irrigation of 150 hectares of agricultural land at Dromolaxia Village, where mainly cultivate corn. The wastewater is also used by the hotels, International Airport and for the use of gardens, parks and fields. For that purpose, the effluent is being discharged through pumping stations. The total cost of the project is 50 million Euro, out of this, 9,3 million Euro is the cost of the treatment plant with the reuse network and pumping station. The cost for the production of treated water is around 0,5 €/m3 (Papadopoulos, 1995). It can be seen that
