The project includes: A). Upgrading of the internal water supply network of Kelli settlement, which amounts to a total length of 12220.9 m. From these pipelines a length of 12114.89 m will go within the approved limits of the settlement of Kelli and a short length of -106.01 m- pipelines will be constructed outside the approved limits of the settlement. This length does not include the interconnector 1K between the two tanks with a total length of 2304,4 m (1171 m the existing section and 1133,4 m the new section). This project is necessary because it will cover and improve the supply of drinking water in the settlement of the Local Community (P.K.) Kelli, in which due to the age of the network and poor operation of the network there is a lack of water. This project will be implemented within a period of approximately 18 months from the accession decision. B) Upgrading of the internal water supply network of the settlement of Agios Panteleimon, which amounts to a total length of pipelines of 24.133 m. From these pipelines 18345,22 m will go within the approved limits of the settlement of Agios Panteleimon and 5787,78 m long will be constructed outside the approved limits of the settlement. This work is necessary because it will cover the needs of drinking water in T.K. Agios Panteleimon, where there is a shortage. This project will be implemented within a period of approximately 24 months from the accession decision. C) Monitoring of construction works by the Ephorate of Antiquities of Florina
