Special Issue Information

Dear Colleagues,

Due to continuous urbanization, there is increasing demand for tap water in cities. Aging infrastructure, emerging pathogens, micropollutants and demand for higher standard from the consumers is creating pressure on water companies. Water distribution networks have become the most vulnerable section of the drinking water supply. Despite the availability of the new types of sensors, information technologies, and analytical methods, the rate of integration of these innovation in water distribution network systems is not sufficient.

The aim of the Special Issue is to gather up-to-date knowledge and the best practices of water quality management in water distribution networks and application of new solutions in the water networks. A wide range of topics including water quality, leakage, water safety plants, quality modelling, hydraulics, and biostability as well social–economical aspects of water in the cities are welcome in this Special Issue.

Abstract

Desalinated seawater enters the urban water supply network on a large scale, which brings new challenges to water quality assurance. In order to strengthen the safety supervision of the pipeline network, ensure the stability of water quality, prevent pipeline corrosion, and avoid the “red water” problem, this study constructed a safety supervision system for desalinated seawater entering the urban water supply pipeline network. In this system, the on-line monitoring system can monitor water quality, water quantity, water pressure and the corrosion of pipeline network in real-time. Early warning system can quickly identify problems and initiate based on the threshold exceeding, statistical analysis, and model prediction. The safety regulation system (including water source regulation system, water quality adjustment system and operation management system) is used to regulate and control water quality problems in the urban water supply network. The application of this safety supervision system is conducive to improving regulation efficiency and ensuring water supply safety. Full article

Abstract

Safe water is becoming a scarce resource, due to the combined effects of increased population, pollution, and climate changes. Water quality monitoring is thus paramount, especially for domestic water. Traditionally used laboratory-based testing approaches are manual, costly, time consuming, and lack real-time feedback. Recently developed systems utilizing wireless sensor network (WSN) technology have reported weaknesses in energy management, data security, and communication coverage. Due to the recent advances in Internet-of-Things (IoT) that can be applied in the development of more efficient, secure, and cheaper systems with real-time capabilities, we present here a survey aimed at summarizing the current state of the art regarding IoT based smart water quality monitoring systems (IoT-WQMS) especially dedicated for domestic applications. In brief, this study probes into common water-quality monitoring (WQM) parameters, their safe-limits for drinking water, related smart sensors, critical review, and ratification of contemporary IoT-WQMS via a proposed empirical metric, analysis, and discussion and, finally, design recommendations for an efficient system. No doubt, this study will benefit the developing field of smart homes, offices, and cities. Full article
