Paros DEYA undertakes all planned sampling checks for drinking water throughout the year in collaboration with privately accredited laboratories based on the legislation and in accordance with the Joint Ministerial Decision Y2 / 2600/2001 “Quality of water for human consumption”.

At the same time, DEYAP has installed 5 water distribution systems, coin or prepaid-card operated, which provide excellent quality soft water to the consumers. They apply the reverse osmosis method to process water of the network, removing part of its hardness.
A typical analysis of the water produced is given in the following table:
