The supply of water to the 35,000 properties that the Board is serving and which are attributable to approximately 70,000 consumers, is done through a water pipe network of length of 357 km, of which 27 km represents the transmission network and 330 km the distribution network. The transmission network consists of main water pipelines having a diameter of 300 - 700 mm, while the distribution network consists of smaller diameter pipes ranging in size from 80 - 300 mm.
Most water pipelines are made of asbestos cement pipes. During the last years, ductile iron is used for the main pipelines and for the subnet pipes plastic (uPVC) is used. For the household connections polyethylene pipes of diameter 15-25 mm are used, while for large consumers such as hotels, residential complexes and factories, larger diameter pipes are used.
