    sensors Article Design and Implementation of a Self-Powered Smart Water Meter Xue Jun Li *,†,‡ and Peter Han Joo Chong †,‡ Department of Electrical and Electronic Engineering, Auckland University of Technology, Auckland 1010, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +64-9-921-9999 † Current address: C-46, 34 St Paul Street, Auckland 1010, New Zealand. ‡ These authors contributed equally to this work. Received: 18 August 2019; Accepted: 19 September 2019; Published: 26 September 2019 Abstract: Smart cities require interactive management of water supply networks and water meters play an important role in such a task. As compared to fully mechanical water meters, electromechanical water meters or fully electronic water meters can collect real-time information through automatic meter reading (AMR), which makes them more suitable for smart cities applications. In this paper, we first study the design principles of existing water meters, and then present our design and implementation of a self-powered smart water meter. The proposed water meter is based on a water turbine generator, which serves for two purposes: (i) to sense the water flow through adaptive signal processing performed on the generated voltage; and (ii) to produce electricity to charge batteries for the smart meter to function properly. In particular, we present the design considerations and implementation details. The wireless transceiver is integrated in the proposed water meter so that it can provide real-time water flow information. In addition, a mobile phone application is designed to provide a user with a convenient tool for water usage monitoring. Keywords: water meter; smart city; automatic meter reading; energy harvesting; flow measurement 1.

Unfortunately, despite the large number of solutions available on the market, the lack of an open and widely accepted communication standard means that vendors typically propose proprietary data collection solutions whose adoption causes non-trivial problems to water utility companies in term of costs, vendor lock-in, and lack of control on the data collection infrastructure. There is the need for open and interoperable smart water metering solutions, capable of collecting data from the wide range of water meters on the market. This paper reports our experience in the development and field testing of a highly interoperable smart water metering solution, which we designed in collaboration with several water utility companies and which we deployed in Gorino Ferrarese, Italy, in collaboration with CADF (Consorzio Acque Delta Ferrarese), the water utility serving the city.

  • 2019 Watersmart Water and Energy Efficiency Project Descriptions
    2019 WaterSMART Water and Energy Efficiency Grants Arizona Colorado River Indian Tribes, Colorado River Irrigation Project SCADA System Modernization Reclamation Funding: $250,000 Total Project Funding: $500,000 The Colorado River Indian Tribes, located in southwest Arizona, will modernize its Supervisory Control and Data Acquisition (SCADA) system on the Colorado River Irrigation Project, including the replacement of 17 pieces of legacy radio telemetry equipment with new high-speed radio telemetry units and 5 remote terminal units. To best utilize the new SCADA system, a new computer and the appropriate software are also included as part of the project. These measures will enable enhanced irrigation water control and management, which are expected to result in annual water savings of 10,000 acre-feet that is currently lost to operational spills and evaporation. This area of Arizona is vulnerable to drought and the Tribes rely on the Colorado River as their sole source of water. The water conserved will be utilized by the Tribes primarily to meet demands on the Reservation, within the limits of their existing water rights. Grover's Hill Irrigation District, GHID Water Delivery Improvement Project Reclamation Funding: $1,500,000 Total Project Funding: $3,141,115 The Grover's Hill Irrigation District, located in Apache County, Arizona, will replace 5.95 miles of existing earthen canals with pressurized high-density polyethylene pipe. The District will also install pressure control valves and 21 flow meters to measure water usage. The District estimates that 51% of their system volume is currently lost due to seepage and evaporation. Once complete, the project is expected to result in annual water savings of 1,705 acre-feet.

Richards, Master of Science Utah State University, 2009 Major Professor: Michael C. Johnson Department: Civil and Environmental Engineering The use of residential secondary or dual water systems for irrigation purposes is common in the western United States where water supplies are scarce. While the use of non-potable water in secondary systems has successfully curtailed demands on potable systems, experience has shown that overall water use actually increases with the introduction of a secondary supply because users commonly pay a fixed fee and have unlimited water use.

Megdal Received: 10 March 2017; Accepted: 23 May 2017; Published: 28 May 2017 Abstract: To reduce the gap between groundwater demand and supply caused by agricultural groundwater over-exploitation, the Prepaid Smart Meter System (PSMS) is being strongly implemented by the Chinese government in northern China. This study reports the analysis and results of PSMS field surveys in six typical provinces in northern China as well as domestic literature reviews. Based on the architecture and implementation policies of the system, the implementation differences between areas and the influencing factors were analyzed, particularly the acknowledgment of farmers, the installation proportion of tube wells, the social benefits. Great achievements have been gained in the implementation, and the management targets have been achieved, including accurately metering overall irrigation groundwater production, assisting in the total amount control and quota management, reducing groundwater exploitation, and improving water use efficiency. However, shortcomings remain in the implementation process, such as single initial investment channels, imperfect policy system construction, a lack of retrieving and analyzing data, and the unbalanced development between areas.

  • Unauthorised Domestic Water Consumption in the City of Alicante (Spain): a Consideration of Its Causes and Urban Distribution (2005–2017)
    water Article Unauthorised Domestic Water Consumption in the City of Alicante (Spain): A Consideration of Its Causes and Urban Distribution (2005–2017) Álvaro-Francisco Morote 1,* ID and María Hernández-Hernández 2 ID 1 Department of Geography, University of Santiago de Compostela, 15782 Santiago de Compostela, Spain 2 Interuniversity Institute of Geography, University of Alicante, 03080 Alicante, Spain; [email protected] * Correspondence: [email protected] Received: 15 May 2018; Accepted: 24 June 2018; Published: 26 June 2018 Abstract: Since 2014 and 2015 numerous projections and macroeconomic indicators have shown sustained growth, allowing governments to affirm that the economic crisis has been overcome. In Spain, the onset of the crisis and the bursting of the real estate bubble (2008) have caused a profound impression on the country and society in recent years. The aim of the study is to analyse the evolution and the determining factors of unauthorised domestic water consumption and its geographic distribution in the city of Alicante (south-east Spain). Methodologically, data have been examined regarding this topic in the city of Alicante for the period 2005–2017 and according to their location and the type of residential property (compact or dispersed). In conclusion, it should be indicated that in Alicante unauthorised consumption is recorded in all social classes and neighbourhoods, especially in the properties of the North District of the city (a lower economic income neighbourhood) but also in those ones that are home to the better-off social classes who reside in detached houses. In the latter, residents commit unauthorised consumption to reduce the high levels of water consumption, aggravated by the current drought (the need to provide greater volumes of water for outdoor uses) and by the increase in the price of water over the last decade.

  • Use of Water Consumption Metering As a Tariff Policy Tool: Moldova’S Experience
    Use of Water Consumption Metering as a Tariff Policy Tool: Moldova’s Experience by S. Drozdov - “Moldova $S &DQDO´ $VVRFLDWLRQ RI :DWHU 6XSSO\ DQG 6DQLWDWLRQ 8WLOLWLHV This report was developed by “Moldova $S &DQDO´ $VVRFLDWLRQ RI :DWHU 6XSSO\ DQG 6DQLWDWLRQ Utilities, incorporating 37 water supply and sanitation utilities of Moldova. The Report highlights the major trends of laws and regulations, underlying application of consumption-based billing in the recent decade, as well as technical and institutional issues, pertaining to installation and use of water counters. Our analysis was based on two typical water supply and sanitation utilities (from the point of view of water metering arrangements and their relations with consumers) - i.e. water utilities that serve Chisinau municipality (the capital of Moldova, 706 thousand residents) and Orkhei municipality (37 thousand residents). We have analysed the growth of measured water sales in 2 recent years and impact of water meters on their consumers (first of all, urban residents). The report reflects the range of problems, associated with reliability of consumption-based billing of water consumers at the level of individual apartments. These problems should be addressed in the course of development of underlying draft laws and regulations for metered billing, as well as for development of tariff policies, forecasts, and water demand management. The document was prepared for the 1st workshop on the municipal water tariff reform in NIS (Paris, February 25-26, 2002). The executive agency: the EAP Task Force of OECD.

  • METERING in CALIFORNIA September 2014
    NEED TO KNOW METERING IN CALIFORNIA September 2014 The drought is prompting a closer look at the use and management of the state’s water resources. One area that has come under increased scrutiny is the use of water meters. While water meters have been in use for decades in most California communities, they are not yet universal. Even in California, more than 219,000 urban water connections remain unmetered. Additionally, the majority of multi-family units have a single meter for all units. Studies show that metering, when coupled with effective pricing structures, reduces water use by 15% to 20%. Additional water savings are possible through improved management of the water system, particularly the identification and repair of leaks in the distribution system. Water savings from metering all connections in California can produce considerable water savings at the local level, reducing vulnerability to drought and other water supply constraints. Moreover, water savings in previous years would have been left in storage. Metering is an essential water management strategy and expanding and improving metering should be a priority for all California utilities. METERING IS ESSENTIAL FOR EFFECITIVE WATER MANAGEMENT Metering is an essential element of effective water management. In the absence of meters, customers are billed at a flat rate – meaning that they pay the same amount regardless of how much water they use. Metering enables utilities to use pricing to encourage water conservation and efficiency. Charging customers by volume sends a price signal to customers to use the resource more efficiently (Renwick and Green 2000; Beecher et al 1994).
