Public Perceptions of Household IoT Smart Water “Event” Meters in the UK—Implications for Urban Water Governance

Abstract

Cities around the world are facing water availability challenges, intensified by increasing populations and climate change. Technology, such as household smart meters measuring domestic water consumption, can play a role in demand management, yet a deeper understanding of public expectations and the practicalities of city-wide implementation is required. This article explores public perceptions of smart water meters that use Internet of Things (IoT) technology and machine learning to profile household water use “events” and anomalies. By leveraging insights from an online survey implemented in the UK (n = 558), this article explores factors influencing the likelihood of citizens choosing to have this type of meter installed along with potential societal barriers and opportunities. Nearly half of the participants said they would choose to have such a meter installed and logistic regression showed predictive variables were younger ages, being male, those with existing water meters and those with other smart devices. The likelihood of choosing this type of water meter was also associated with preferences to have control over data privacy, whether the meter would reduce water bills and whether it was provided free of charge. We locate these results within other contemporary experiences of smart meters and water grids in urban contexts to discuss practical challenges of using real-time environmental data for urban water governance. Policymakers and water resources planners should continue to monitor public perceptions, implement urban experiments and cost-benefit analyses to better interpret the wider benefits of such technology for behavioral and educational interventions within a more digitized and increasingly data-centric water grid.

Is smart water meter temporal resolution a limiting factor to residential water end-use classification? A quantitative experimental analysis

“…Ultimately, disaggregating and classifying water events obtained from residential smart water meter data reveals detailed information about how water is consumed within households. Understanding water consumption profiles and performance of different resolutions presents opportunities for improved residential water conservation and efficiency and long-term water resource sustainability (Attari 2014, Inskeep and Attari 2014, Goulas et al 2022. Our study presents an experimental example of how using smart water meter data can provide end-use information to pinpoint opportunities for improved efficiency within residential buildings.…”

An Exploration of Customers’ Satisfaction with Water and Wastewater Services in the UK

“…So, while trust might be hard to shift through occasional factual communications (such as water quality reports, Johnson 2003), social media campaigns might have some role to play in the longer-run in improving engagement and CS (particularly in younger age groups), under the caveat that social media more generally is also vulnerable to the spread misinformation that can foster distrust (Limaye et al, 2020). Emerging findings elsewhere suggest opportunities to explore the use of interactive data through digital water sensors and smart water meters as ways to promote transparency and perceived procedural fairness to help build trust and improve satisfaction (Beal & Flynn, 2015;Goulas et al, 2022)…”

AI explainability and governance in smart energy systems: A review

“…This parameter is about investigating AI governance's role in promoting sustainable energy and sustainable development without putting essential energy requirements at risk and considering strategies to fight climate change. It captures different dimensions of "Sustainable Energy and Climate," including AI-powered solutions to achieve sustainable energy (Saheb et al, 2022), the aspects of water governance in urban areas (Goulas et al, 2022), the significance of AI in promoting sustainable development in the water, food, and energy industries (D'amore et al, 2022), sustainable education and society in the energy domain (Skowronek et al, 2022), and the governance of AI to confront climate change and achieve sustainable development (Raper et al, 2022).…”
