Adaptive approaches are required to counteract the mounting threats to water security. Demand management will feature centrally in such adaptation. The increase in use of smart meter technology offers an improved way for utilities to gauge consumer demand and to
supply consumers with consumption feedback in (near) real-time. Such feedback can
decrease the discrepancies between perceived and actual water usage. In contrast to the
energy sector, however, where the advantages associated with smart meter consumption
feedback are extensively documented, few studies have focused on the usefulness of such
feedback when it comes to managing water consumption. This review assesses the evidence
base for the effectiveness of water usage feedback technology in encouraging water
conservation. The review highlights the potential value of high-granular smart-meter
feedback technology in managing domestic water consumption. Findings from the papers included in this review (N = 21) indicate that feedback was associated with decreases of between 2.5% and 28.6% in water use, with an average of 12.15% (SD = 8.75). A single paper reported a 16% increase in consumption associated with smart-meter feedback. The benefits for water utilities are highlighted, but the costs for utilities need to be considered further. Overall, more work is needed to conclusively pinpoint the most effective type of feedback in terms of information content and granularity, frequency of delivery and medium, and how water consumption is linked to energy consumption. This information is needed to make concrete recommendations to the water industry about the costs and benefits of
investment in smart metering and consumer feedback.
