Smart Water System and Internet of Things

Abstract

Objective: Today, Internet of Things (IoT) technology has a significant impact on overcoming the challenges of water loss. The IoT also helps the reducing of these challenges. This study aims to show how can by reducing the water working pressure, water saving happened through IoT. Methods: In this work, water loss in the distribution network was investigated for smart water. Smart water systems can be achieved by advanced pressure management. The water pressure changes during the day and night can lead to water losses. In this work, the network pressure variations were recorded by IoT through geospatial modeling. The difference between the present work and the previous works was the emphasis on advanced techniques including networked sensors, remote sensing, geographic information systems (GIS), and the IoT. The pressure changes analysis was carried out by WaterGEMS software and ArcGIS-ArcMap software. Results: The results showed the average water saving in 6 days after the completion of the work. The water saving was reported as 527.66m3 per day equivalent to 1.22L/h noticeably more than half 41.83% of the water which was stored during the time of extra pressure. It happened especially from 4:00 midnight to 6:00 a.m. when Minimum Night Flow decreased to 405 cubic meters per hour. Conclusion: The amount of water entrance to the network and the saving percentage were assumed as dependent and independent variables for regression analysis. The results showed the power function had a suitable correlation due to the scatter diagram and P-value.
