Abstract

Water scarcity and water stress issues pose a serious threat to the global population. Climate change, drought, population growth and consolidation in urban centres have all been increasing the pressure on water service providers to deploy more sustainable approaches in urban water management. Real-time monitoring and control of water consumption are key ingredients for a smart water management system which will raise consumers’ environmental awareness and reduce costs. This paper introduces a smart infrastructure system which enables remote telemetry and control of water consumption via a web application. The bidirectional and reliable communication between terminal devices (smart meters and valves) and the end-user (consumers and water utility operators) is realized through a fixed hybrid network which uses multiple telecommunication protocols. The metering data is collected and further processed through modern data analytics tools to give a deeper insight on water consumption and behavioral patterns.

... The use of satellite imagery as a data source in urban planning also helps identify climate-friendly solutions (Milojevic-Dupont et al., 2020). Web-based water management (Mourtzios et al., 2021) can be supported with trends identified from time-series data (Ise et al., 2020), but remotely sensed water flow data also complements the agricultural water management model (Ismail et al., 2020). And if we increase the resolution of the data (Jimenez et al., 2019), we can also understand the causal relationships related to consumption. ...
... Statistical downscaling (Wang Q. et al., 2020) helps to find the external variables of Mourtzios et al. (2021) consumption patterns identified based on remote sensing and is comparable with the results of satellite image-based analyzes (Semlali and El Amrani, 2021). And comparable to other approaches (Jimenez et al., 2019), which strengthens confidence in the models (Qin and Chi, 2020). ...
... Population movements (Gurram et al., 2019) affect water consumption (Mourtzios et al., 2021), can damage plants (Meineke et al., 2020), show the popularity of coastal areas (Kubo et al., 2020), but are also suitable for improving transport planning (Hu et al., 2020). Because the movement of residents is closely related to the infrastructure (Milojevic-Dupont et al., 2020), it is a very valuable input in urban planning. ...

The aim of this paper is to provide an overview of the interrelationship between data science and climate studies, as well as describes how sustainability climate issues can be managed using the Big Data tools. Climate-related Big Data articles are analyzed and categorized, which revealed the increasing number of applications of data-driven solutions in specific areas, however, broad integrative analyses are gaining less of a focus. Our major objective is to highlight the potential in the System of Systems (SoS) theorem, as the synergies between diverse disciplines and research ideas must be explored to gain a comprehensive overview of the issue. Data and systems science enables a large amount of heterogeneous data to be integrated and simulation models developed, while considering socio-environmental interrelations in parallel. The improved knowledge integration offered by the System of Systems thinking or climate computing has been demonstrated by analysing the possible inter-linkages of the latest Big Data application papers. The analysis highlights how data and models focusing on the specific areas of sustainability can be bridged to study the complex problems of climate change.

Internet of Things (IoT) enabled technologies transform industries, envisioned as an ecosystem of billions of interconnected devices. Enhanced connectivity and the rapid development of wireless sensors have caused radical changes on how societies interact and behave. Smart metering, in the context of Smart Cities ecosystem, is advanced by IoT development, aiming at improving citizens' quality of life. Creating cloud-based networks of networked devices requires a low-cost and reliable means for non-IP based devices to seamlessly connect to Internet. Furthermore, device heterogeneity in terms of protocol and data format, hinters large scale deployments and introduce vendor and protocol lock-in issues. This technological gap calls for novel IoT gateways which reliably bridge wireless devices to the Internet. This paper reports an experimental study of a Multi-Protocol gateway which can interact with a plethora of different end devices (water meters, water valves) and constitute the building block of a fixed and wireless network which renders real time telemetry and remote control of water consumption feasible.
Chapter
Throughout the past years, the Indian government is putting its best efforts in developing smart cities by applying smart solutions for infrastructures and services. Smart water management is one of the key service areas where now it is a high time to work for. Many industries and researchers are contributing to incorporate smart techniques for smart water system like sensor-based monitoring, real-time data transmission and controlling, leakage management, water distribution management and many more. Nevertheless, the design and proposal of such a smart water system are still not fairly standardized. The enormous applications of smart water management still do not have systematic framework to guide real-world design and deployment of a metering system. To address this challenge, a framework is designed and tested with prototype implementation. This paper mainly focuses on minimizing smart water metering application development efforts. The framework uses open-source technologies and has mechanisms like device installation, water usage statistics, bill payments and a distributed data transmission architecture.

The rapid growth of Internet-of-Things (IoT) in the current decade has led to the development of a multitude of new access technologies targeted at low power, wide area networks (LP-WANs). However, this has also created another challenge pertaining to technology selection. This paper reviews the performance of LP-WAN technologies for IoT, including design choices and their implications. We consider Sigfox, LoRaWAN, WavIoT, random phase multiple access (RPMA), narrow band IoT (NB-IoT) as well as LTE-M and assess their performance in terms of signal propagation, coverage and energy conservation. The comparative analyses are based on available data sheets and simulation results. A sensitivity analysis is also conducted to evaluate network performance in response to variations in system design parameters. Results show that each of RPMA, NB-IoT and LTE-M incurs at least 9 dB additional path loss relative to Sigfox and LoRaWAN. This study further reveals that with a 10% improvement in receiver sensitivity, NB-IoT 882 MHz and LoRaWAN can increase coverage by up to 398% and 142% respectively, without adverse effects on the energy requirements. Finally, extreme weather conditions can significantly reduce the active network life of LP-WANs. In particular, the results indicate that operating an IoT device in a temperature of -20 degree Celcius can shorten its life by about half; 53% (WavIoT, LoRaWAN, Sigfox, NB-IoT, RPMA) and 48% in LTE-M compared with environmental temperature of 40 degree Celcius.

This report provides the findings of a third party evaluation of a major smart metering project conducted by Wide Bay Water Corporation (WBWC). The Evaluation has been undertaken by the Snowy Mountains Engineering Corporation (SMEC) and the Institute for Sustainable Futures (ISF), at the University of Technology, Sydney, on behalf of the Department of the Environment, Water, Heritage and the Arts (DEWHA). WBWC has installed the first residential automatic water meter reading (AMR) system in Australia on a city-wide scale and are the first utility internationally to require an advanced level of data storage, issue reporting and data manipulation functionality at this scale1. The AMR Project “Wide Bay Water Smart Metering and Sustainable Water Pricing Initiative Project” has been funded in part by the Australian Government’s Water Smart Australia Program. It has involved the installation of over 20,000 residential AMR water meters in phases since 2006 and the set-up of the associated data capture, billing and management systems. This AMR Project represents an extremely important step forward in understanding how this rapidly emerging technology can be used effectively in water planning and management. The experience of WBWC can be used to provide insight into how the implementation process has and could be undertaken but also to assist in setting direction for future AMR systems taken up in Australia.

Due to growing water needs, depletion and degradation of existing water resources and climate change, the need for sustainable and efficient management of the available water resources is more urgent than ever. Considering the urban use, the lack of reliable data of water use metering is one of the most important issues that complicate this effort. Water flow meters are the main instruments to provide monitoring of the actual amount of water consumed. The majority of water utilities choose to use flow meters with low measuring accuracy. This results in under-registration of the actual water consumption, creating thus actual consumption demand deficiencies and significant revenue losses for the utility. Meanwhile, the metering data are usually collected three or four times a year and as a result their use is limited to the billing process of the user's consumption. Aiming at the reduction of the amounts of non-revenue water, the continuous monitoring of consumption and the automation of the operational processes, the Water Supply and Sewer Utility of Thessaloniki (E.Y.A.TH.) is orientated to the adoption of new metering technologies and the creation of databases with consumption patterns. In this perspective, an experimental application of fourteen positive displacement meters (oscillating piston meters) of high measuring accuracy, in conjunction with an automated system for recording and transmitting consumption data, has been developed in collaboration with the water utility. The positive displacement meters were installed in serial to the existing velocity meters (single jet meters). From the analysis of the metering data of these flow meters, the amounts of non-revenue water and the financial losses of the utility are measured for specific period of time, namely thirty days, four months and a whole year. Simultaneously, an estimation of these amounts is made for a larger amount of connections that have the same characteristics. The amounts of non-revenue water that were detected are at such high levels that is considered more appropriate and at the same time more effective to replace the existing flow meters with new, of increased metering accuracy. The detailed analysis of the collected data has revealed the periods of increased consumption activity during the day, giving thus the opportunity of useful recommendations for a more efficient use and a targeted pricing policy according to the consumers' water consumption characteristics.

SmartH2O is a software platform that creates a virtuous feedback cycle between water users and the utilities, providing users information on their consumption in quasi real time, and thus enabling water utilities to plan and implement strategies to reduce/reallocate water consumption. The SmartH2O platform adopts a gamification paradigm to motivate users to change their water use behaviour and different incentives (virtual, physical, and social) are used to stimulate the competition among users. The SmartH2O platform, developed during the EU-FP7 project that bears the same name, has been deployed in two test sites: in Terre di Pedemonte, a small municipality in Tessin, Switzerland, and in Valencia, a large urban centre, in Spain. Thanks to its use it has been observed an average reduction in consumption of 10% in Switzerland and of 20% in Spain among the platform adopters.

We explore the state of the art in solutions for low power wide area (LPWA) networks and technologies serving the Internet of Things (IoT) and Connectivity for Everything markets. These networks are forecast to capture up to 55% market share using battery-powered devices operating up to 10 years and link distances measured in tens of kilometers. In this paper, we survey two LPWA technologies; ultra-narrow band solutions by SigFox and the LoRa technology by Semtech. Both technologies operate in the licence-exempt industrial, scientific, & medical (ISM) bands (EU 868 MHz / US 915 MHz). We survey both solutions in terms of physical layer (PHY) and associated medium access control (MAC) capabilities from an end-to-end system viewpoint. We then proceed to explore coverage ranges in eastern Ireland. We present results indicating a potential coverage area of 3, 800 km 2 and from a real-world experimental test case involving the use of SigFox's technology operating over a 25 km test link between a 25 mW LPWA client test and a basestation. Finally, we provide example results demonstrating a received SNR consistently exceeding 20 dB over this test link distance.

The fundamental role of policymakers when considering Advanced Metering Infrastructure (AMI), or ‘smart meters for energy and water infrastructure is to investigate a broad range of complex interrelated issues. These include alternative technical and non-technical options and deployment needs, the cost and benefits of the infrastructure (risks and mitigation measures), and the impact of a number of stakeholders: consumers, distributors, retailers, competitive market operators, competing technology companies, etc. The scale and number of potential variables in the AMI space is an almost unprecedented challenge to policymakers, with the anticipation of new ancillary products and services, associated market contestability, related regulatory and policy amendments, and the adequacy of consumer protection, education, and safety considerations requiring utmost due-diligence. Embarking on AMI investment entails significant technical, implementation, and strategic risk for governments and administering bodies, and an active effort is required to ensure AMI governance and planning maximises the potential benefits, and minimise uncertainties, costs, and risks to stakeholders. This work seeks to clarify AMI fundamentals and discusses the technical and related governance considerations from a dispassionate perspective, yet acknowledges many stakeholders tend to dichotomise debate, and obfuscate both advantages and benefits, and the converse.

Reliance on the standard cumulative kilowatt-hour metersubstantially compromises energy efficiency and demand response programs.Without advanced metering, utilities cannot support time-differentiatedrates or collect the detailed customer usage information necessary to (1)educate the customer to the economic value of efficiency and demandresponse options, or (2) distribute load management incentivesproportional to customer contribution. These deficiencies prevent thecustomer feedback mechanisms that would otherwise encourage economicallysound demand-side investments and behaviors. Thus, the inability tocollect or properly price electricity usage handicaps the success ofalmost all efficiency and demand response options. Historically,implementation of the advanced metering infrastructure (AMI) necessaryfor the successful efficiency and demand response programs has beenprevented by inadequate cost-benefit analyses. A recent California efforthas produced an expanded cost-effectiveness methodology for AMI thatintroduces previously excluded benefits. In addition to utility-centriccosts and benefits, the new model includes qualitative and quantitativecosts and benefits that accrue to both customers and society.

Few means currently exist for home occupants to learn about their water consumption: e.g., where water use occurs, whether such use is excessive and what steps can be taken to conserve. Emerging water sensing systems, however, can provide detailed usage data at the level of individual water fixtures (i.e., disaggregated usage data). In this paper, we perform formative evaluations of two sets of novel eco-feedback displays that take advantage of this disaggregated data. The first display set isolates and examines specific elements of an eco-feedback design space such as data and time granularity. Displays in the second set act as design probes to elicit reactions about competition, privacy, and integration into domestic space. The displays were evaluated via an online survey of 651 North American respondents and in-home, semi-structured interviews with 10 families (20 adults). Our findings are relevant not only to the design of future water eco-feedback systems but also for other types of consumption (e.g., electricity and gas).

Automatic meter reading (AMR) is the remote collection of consumption data from customers' utility meters over telecommunication, radio, power-line and other links. Electric utilities are exploring the usage of AMR data for outage management for distribution systems. Signals from automated meters can provide additional information in the outage detection and determination processes as well as restoration phases of outage management. However due to its low quality, AMR outage data cannot be fed directly into outage management systems. This paper details the development of an intelligent information filter for automated metering systems. The filter prevents false outage notifications in addition to improving the quality of outage data. The nature of wireless communication in the AMR system introduces uncertainty issues in the query process. This uncertainty has been modeled using probabilistic and fuzzy engineering techniques. The filter has also been tested using historical outage data
