It has been estimated worldwide that the volume of non-revenue water reached 126 million cubic meters per year at a cost of more than 39 million dollars per year. In Ecuador, according to the Water Regulation and Control Agency (ARCA), the average of these losses was 47.23% for the year 2022, a value that implied an economic detriment of US$320 million. This agency stated that in general terms, almost half of the water is lost due to leaks, bad connections, or aging pipes. At the Universidad de las Fuerzas Armadas - ESPE, the percentage of non-revenue water has been determined thanks to the use of flow meters with IoT technology, which allows measuring in real time the behavior of the incoming flow, in addition, wastewater measurement campaigns were carried out to perform a water balance. In this context, the objective of this study was to perform a water balance of the Library and the Integrated Health System (SIS), using the water consumption data of the library obtained thanks to the flow meter, while the SIS, not having this type of device, the probable maximum flow was estimated following the Hydrosanitary Regulation NEC-11; this work was complemented with the implementation of a wastewater measurement campaign, which revealed non-revenue water of 56.34%. This value demonstrated the importance of flow meters to obtain real consumption data in the SIS, avoiding theoretical estimates.

摘要

It has been estimated worldwide that the volume of non-revenue water reached 126 million cubic meters per year at a cost of more than 39 million dollars per year. In Ecuador, according to the Water Regulation and Control Agency (ARCA), the average of these losses was 47.23% for the year 2022, a value that implied an economic detriment of US$320 million. This agency stated that in general terms, almost half of the water is lost due to leaks, bad connections, or aging pipes. At the Universidad de las Fuerzas Armadas - ESPE, the percentage of non-revenue water has been determined thanks to the use of flow meters with IoT technology, which allows measuring in real time the behavior of the incoming flow, in addition, wastewater measurement campaigns were carried out to perform a water balance. In this context, the objective of this study was to perform a water balance of the Library and the Integrated Health System (SIS), using the water consumption data of the library obtained thanks to the flow meter, while the SIS, not having this type of device, the probable maximum flow was estimated following the Hydrosanitary Regulation NEC-11; this work was complemented with the implementation of a wastewater measurement campaign, which revealed non-revenue water of 56.34%. This value demonstrated the importance of flow meters to obtain real consumption data in the SIS, avoiding theoretical estimates.
