The object of the contract concerns the construction of the following infrastructures: i. the 18 km main adduct, ii. the primary and secondary irrigation network (distribution networks) with a length of 93 km, iii. the tertiary network with a length of 685 km, iv. the necessary E/M installations and equipment for the proper operation of the network and finally, v. the interventions that will be deemed necessary for the improvement/upgrading of the abstraction works. The construction of the Project will be implemented with the parallel construction of two distinct sections, "Subproject 1" and "Subproject 2 (remaining project)" which make up the whole Project. Subproject 1 should operate autonomously for the period from Subproject 1 Service Availability Date to Service Availability Date. In particular, according to the design of the project as a whole, the construction of two new closed transport-supply pipelines under pressure (Pipes A and B) will be connected to the existing twin pipelines which drain water from the reconfiguration tank (central abstraction) and will run parallel to the route of the adductor canal up to its contribution to the existing provider. Up to this position, the western sector (Pipe A) will supply the upstream pipelines of the distribution network, while the eastern sector (Pipe B) will run without branches. In the place of the divider, the western branch will terminate its route, supplying the downstream distribution pipelines, while the eastern branch will continue its route, following the route of the downstream section of the adductor canal. Until the end of its route, the eastern branch will supply the parties to it, distribution pipelines. The western branch (Pipe A) will supply part A of the network (13 irrigation sectors) and the eastern branch (Pipe B) will supply part B of the network (11 irrigation sectors). The function of the benefit dividend as a sharing pool will be abolished. In order to serve the need for the autonomous operation of Subproject 1, the existing operation of the benefit dividend as a sharing pool will remain for as long as the tertiary networks of Subproject 1 will be supplied with irrigation water from the existing adductor canal. Subproject 1 includes the construction of: a) the tertiary networks of the irrigation sectors 1,2,3,4,6,7,8,9,10,11,12 and 13 of Section A of the network including the transmission and distribution networks supplying the tertiary networks and b) the necessary E/M installations and equipment for the proper operation of the network. Subproject 2 includes the construction of: (a) the interventions deemed necessary to improve/upgrade the abstraction works, (b) the transmission-supply pipelines (Pipes A and B), (c) the tertiary networks of irrigation sectors 5 of Section A and 14,15,16,17,18,19,20,21,22,23 and 24 of Section B of the network including the transmission and distribution networks supplying the following tertiary networks. (d) the necessary E/M installations and equipment for the proper operation of the network and (e) the required Integration Operations
