The project concerns the supply and installation of a leak control system in existing water transmission and distribution networks of the Municipal Water Supply Company of Kalamata (DEFAK) in order to ensure the adequacy and quality of drinking water in its areas of responsibility.With the current operation of the networks, the water system operates without single planning, methodological adequacy and know-how, as there is no single system for monitoring the infrastructure of the external network and monitoring stations of critical parameters and leakages in the internal network. The natural result is that water resources are not managed rationally and squandered due to overflows and breaks due to overpressures and the absence of a network and leak monitoring system. As a result, significantly increased loss indicators are observed which make the network functioning unprofitable and do not ensure a smooth supply to consumers. This makes the implementation of this project imperative, so that, with the installation of planned leak detection equipment, the network is monitored and managed on a single basis, both quantitatively and qualitatively.The deliverable of the project will be an integrated system of control-remote control, reduction of leakage through control and adequacy of the quantity and quality of the water provided in which will be monitored, from the headquarters of the DEAK, the operational situations in the area, the operating conditions shall be provided in the appropriate area. With the implementation of the project, it is planned to develop an appropriate model for the more efficient operation of the network, which will end the current problem of quantitative and qualitative competence. DEYAK has installed in 22 locations of the network (tanks, pump rooms and drilling) a local automation system, through which the infill of the tanks is controlled. The proposed system will not interfere with these infrastructures but will be able to integrate the information from these stations with the aim of providing information and data on all the infrastructures, which will now cover 95 % of the network.
