Real time monitoring and control in water distribution systems for improving operational efficiency

Abstract

A B S T R A C TThe global water sector faces challenges to maintain safe, healthy, and adequate water supply to its consumers. Control of water quality and quantity by real-time monitoring (RTM) plays an important role in the management of water distribution systems (WDSs) and protection of consumers' health. RTM could be used for monitoring and analyses of water quality parameters to ensure its suitability for drinking. Additionally, RTM system warns operators to stop water supply to save water and minimize risks when needed. WDS of Antalya City is monitored and controlled by an advanced RTM and Supervisory Control and Data Acquisition (SCADA) system. Integrated RTM-SCADA system monitors and controls both hydraulic and water quality parameters to improve the WDS's operational efficiency. The system automatically controls pumps and valves and it has security alarms if any of the monitored water quality parameters fail to comply with the drinking water quality standards. This feature helps to protect WDS from the adverse impacts of an intentional or unintentional contamination event. Furthermore, RTM system is very helpful to detect water losses. Integrated RTM-SCADA system in WDSs provides many operational benefits (improved water quality, decreased operational costs, reduced customer complaints, reduction in water losses, and modeling capability) but it requires a good management system to assess huge amount of collected data.

A Real-Time Augmented Reality System for Water Distribution System

“…The integrated RTM-SCADA-AR system can be reliable at 100% for a proper water distribution system control and management. However, its implementation still very expensive, the payback period is estimated to be less than one year when all the other benefits are considered [7]; the Developing country cannot afford the implementation due to the cost. The present paper strongly recommends more founded study for developing a low-cost real-time system to facilitate the implementation in the developing country.…”

“…Combined RTM-SCADA with augmented reality to display a water distribution network. Based on the proposed architecture in [7], we build the RTM-SCADA-AR system. The output information from the previous architecture will be used as integrated parts to the AR application in order to visualise it in a real-time situation.…”

“…Research has been funded for the design and the test of various online real-time facilities for monitoring and controls a drinking water system [3][4][5] [6]. Real-Time Monitoring (RTM) Ability can be used as a tool for measuring and controlling a Water distribution system [7]. The large volumes of data generated from real-time control, make the Supervisory Control and Data Acquisition (SCADA) system to be suitable for utilization and processing for real-time data acquisition [8].…”

The strategic development for water loss prevention

“…In order to use this method effectively, the network hydraulics should be separated from each other in the District Metered Areas (DMA) (Farley and Liemberger 2005;Xin et al 2014). As the DMA flow at the entrance is very sensitive, the measurements should be made with sensitive flow meters (Rıchards et al 2010;Kara et al 2015). Any leakages of the pipelines within the network could be determined earlier during the measurements as the flow starts to increase and exceeds pre-determined limits.…”

Human Health Impact Analysis of Contaminant in IoT-Enabled Water Distributed Networks

“…Water utilities' fundamental duties are to provide and distribute water to customers of an acceptable quality, quantity, and pressure through the entire water distributed system (WDS) [4]. The usable water is at first treated to meet the drinking water quality standards before delivery [5]. Because of the spatial scale and the high complexity of water distributed networks, adverse accidental incidents commonly occur.…”
