The project concerns the definition and demarcation of zones and measures for the protection of water catchment points, intended for human consumption from underground water bodies in Corfu and aims to protect water sources from polluting activities. The implementation of the project will result in significant benefits for the protection of the health of the island’s population.Due to the large number of sources used in Corfu, the overall project is planned to be carried out in 2 phases. The Municipal Corporation Water Supply and Sewerage of Corfu (DEFAK) uses 180 drilling sites for the water supply of its area of responsibility. Of these, the 43 will be included in the present phase of demarcation of protection zones, based on the importance of the provision size and the serviced population.
