PROJECT DESCRIPTION<\/h2>\n

This system enables the monitoring, remote control, remote operation, and leak detection of the main water supply network of the Municipality of Xylokastro.<\/p>\n

    \n
  • Twelve (12) Local Control Stations<\/strong>\u00a0(LCS)<\/strong>\u00a0for hydraulic\u00a0Central Network<\/strong>\u00a0were installed at key points of the water supply network.\nThey collect data from the connected components\u2014such as flow rates, pressures, etc.\u2014and transmit them via a GSM wireless network to the Central Control Station (CCS) for further processing.\nDepending on demand, they can adjust the pressure in the network zones they monitor, thereby reducing network leaks as well as damage caused by high pressure (e.g., pipeline bursts).\nThis extends the lifespan of the network and simultaneously saves water for the Municipal Water and Sewerage Company of Xylokastro<\/li>\n
  • A Central Control Station (CCS),<\/strong>\u00a0where operators can access and control all or part of the system\u2019s functions using an appropriate password.\nInformation on the operational status and system faults is provided through the remote monitoring\/control software (SCADA).<\/li>\n<\/ul>\n

    BRIEF DESCRIPTION OF OPERATION<\/strong><\/p>\n

      \n
    1. Springs \u2013 Boreholes \u2013 Reservoirs<\/strong><\/li>\n<\/ol>\n

      The system continuously monitors<\/strong>\u00a0by the supply from the springs, the system issues\u00a0a command\u00a0<\/strong>to stop the operation of the boreholes.\nIn cases where the spring supply is insufficient to meet consumption needs,\u00a0appropriate alerts<\/strong>\u00a0are sent to the operator, and the borehole pumps are\u00a0automatically<\/strong>\u00a0activated.\nThe system also constantly monitors the readings from the flow meters, and when these readings exceed the permitted limits, appropriate messages are issued to the operator.<\/p>\n

        \n
      1. Water Pumping Station \u2013 Reservoirs<\/strong><\/li>\n<\/ol>\n

        The water\u00a0level<\/strong>\u00a0of\u00a0the inlet reservoir,<\/strong>, \u03b7\u00a0the outflow at the pumping station's exit,<\/strong>\u00a0and the level of the reservoir supplied by the pumping station are continuously monitored.\nWhen the reservoir level reaches the lower permissible limit, a command is issued\u00a0to start a pump.<\/strong>The system selects to start the pump with the fewest operating hours first, followed by the pump with the next fewest hours, and so on.\nThis ensures balanced usage across all pumps.\nIf the inlet reservoir\u2019s water level drops below the minimum allowed limit, appropriate warning messages are sent to the operator, and the necessary actions are automatically carried out\u2014such as\u00a0stopping<\/strong>\u00a0of\u00a0the operation<\/strong>\u00a0of the pumps.<\/p>\n

          \n
        1. Finally, all the above information is collected at the\u00a0Central Control Station<\/strong>\u00a0(CCS),<\/strong>\u00a0located at the offices of the Municipal Water and Sewerage Company.\nFrom there, the operators take the appropriate actions to ensure the optimal operation of the system.<\/li>\n<\/ol>\n

          For the operation of the remote monitoring and control system, the following equipment was installed:<\/p>\n

          One (1) Central Control Station (CCS)<\/strong>\u00a0with the following auxiliary equipment:<\/p>\n

            \n
          • One (1) communication processor<\/li>\n
          • One (1) PC (Personal Computer)<\/li>\n
          • One (1) monitor<\/li>\n
          • One (1) laptop computer<\/li>\n
          • One (1) UPS (Uninterruptible Power Supply)<\/li>\n
          • Two (2) software programs for computer use<\/li>\n
          • One (1) Remote Monitoring\/Control software program (SCADA)<\/li>\n
          • One (1) software package for local and remote programming of PLCs.<\/li>\n<\/ul>\n

            Twelve (12) Local Control Stations (LCS)<\/strong>\u00a0at boreholes and reservoirs, including the following equipment:<\/p>\n

              \n
            • Twelve (12) PLC programming software licenses<\/li>\n
            • Eighteen (18) electromagnetic flow meters<\/li>\n
            • Seven (7) analog pressure sensors<\/li>\n
            • Seven (7) analog level sensors<\/li>\n
            • Thirteen (13) level switches<\/li>\n
            • Thirteen (13) current transducers for current transformers (CTs)<\/li>\n
            • Twelve (12) electrical installations housed in pillars.<\/li>\n<\/ul>\n

              Benefits of the system during operation:\u00a0<\/strong><\/p>\n

                \n
              • the timely identification of the source of potable water losses and the immediate response to leaks and overflows, resulting in the reduction of annual losses and overall consumption within the Municipality's water supply network.<\/li>\n
              • the reduction of the pumping station's energy consumption through controlled pump operation, as well as their protection from voltage faults, water shortages, etc.<\/li>\n
              • the continuous recording of consumption (inflows and outflows of the reservoirs and the network), which provides information on any significant leaks.<\/li>\n
              • the immediate notification and response of the responsible technical personnel to any faults (24-hour monitoring), such as pump failure (water shortage in the network), sudden pressure drop (leak), or sudden flow increase (pipeline break).<\/li>\n<\/ul>\n
