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>\nBRIEF DESCRIPTION OF OPERATION<\/strong><\/p>\n\nSprings \u2013 Boreholes \u2013 Reservoirs<\/strong><\/li>\n<\/ol>\nThe 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\nWater Pumping Station \u2013 Reservoirs<\/strong><\/li>\n<\/ol>\nThe 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\nFinally, 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>\nFor the operation of the remote monitoring and control system, the following equipment was installed:<\/p>\n
