The water resources play a key role in the regional development and therefore, it is important to address sustainable - oriented management practices. Considering that the agricultural sector has a great impact on water resources consumption, irrigation infrastructures have to be carefully built and used in order to utilize water resources in a sustainable way.
An indicative example of a typical irrigation problem concerning agriculture is the situation in the Municipality of Souli. Hence, this paper will use as a point of departure the case study of the nearby Kokitos stream, which could be part of a multi-faceted solution. The demand-supply balance for Kokitos showed that, if its stream water resources are utilized, they could cover 41,4% of the total watering area, while the current infrastructure can be used during the summer. Hence, under certain conditions, we suggest that a water-tank is constructed, decreasing the current total irrigation cost by 18%.
