Crete is a self-sufficient place in potable water. Freshwater is coming straight from the White Mountains and Psiloritis, two nature blessed mountain formations, assuring the water adequacy for the whole region.
The west part of the island is relatively wetter than the east side, and the mountains get more rainfalls over the year. The drinking water sources for the north side of Chania prefecture are groundwater, lakes, and natural springs at the foothills of the White Mountains. In the southern parts of Chania, drinking water originates from local groundwater wells.
