TEMPORAL EVOLUTION OF THE STATUS OF THE WATER SUPPLY AND SEWERAGE SYSTEMS IN NORTHERN GREECE DURING 1988-2004

摘要

In this research, data of the National Statistical Service of Greek, the archives of the Laboratory of Hygiene of the Aristotle University of Thessaloniki have been taken into consideration, and also data analyses of relative questionnaires sent to 1350 municipalities departments of Macedonia and Thrace. This research has been carried out within the framework of a project supported by the Ministry of Macedonia-Thrace, Greece. The main issues examined in this research were the sufficiency of drinkable water, its chlorination, the condition of the water supply network, and the number of residencies connected with the central sewage system. It has been confirmed that in 2004 79% of the municipalities had un-interrupted water supply instead of 66% in 1988, whereas population increased from 52% to 61%. Residencies which are connected to the sewage system come up to 73% in 2004, while in 1988 they were only 56%. In 2004, 87% of the municipalities in Northern Greece (that is 96% of the population) use systematic chlorination. Also 46% of the municipalities in Northern Greece (57% of the total population) have water supply networks in a sufficient state.
