The project concerns the construction of new water supply networks within the settlement of the Municipal Community of Mytilenes of the Municipality of Samos. The new water supply networks will replace existing ones, which are mainly made of asbestos tubes and iron pipes. At the same time, some sewerage systems will be replaced, which are to be damaged during the construction of the water supply networks. Its implementation is a constant demand of the local community, as the current situation degrades the quality of life and creates problems for economic activity. The implementation of the project is a prerequisite for economic development, while its contribution to environmental protection is self-evident and extremely important since the losses in the existing outdated network exceed 50 %.
