The project concerns the upgrading of the water supply infrastructure in the Local Communities of the Municipal Units of Meliti, Passage and Kato Klinen of the Municipality of Florina. The aim is to reduce the waste of drinking water, which is a particular problem in the mountainous and disadvantaged areas of the Municipality of Florina, but also to ensure as much as possible the adequate supply of water to consumers, as well as the protection of public health. The above will be achieved through the control of the quality and disinfection of the water supplied.
