Consumption-based feedback has been demonstrated to encourage water conservation behaviors. Smart meters and digital solutions can support customized feedback and reinforce behavioral change. Yet, most of the studies documenting water conservation effects induced by feedback and smart meter data visualization evaluate them in short-term experimental trials only. Here we show that water conservation behaviors promoted by smart meter-based consumption feedback and digital user engagement interventions might persist in the long term. We developed an analysis of 334 households in Valencia, Spain. We find that approximately 47% of the households engaged in our water conservation program achieved a long-term 8% reduction of volumetric water consumption, compared with pre-treatment observations. Water conservation behaviors persisted more than two years after the beginning of the program, especially for the households receiving sub-daily smart meter information. Our results provide empirical evidence that smart meter-based water consumption feedback and digital user engagement can effectively promote durable conservation behaviors.

通过基于智能仪表的反馈和数字用户参与来促进长期节水

基于消耗的反馈已被证明可以鼓励节水行为。智能电表和数字解决方案可以支持定制的反馈并加强行为改变。但是,大多数记录反馈和智能仪表数据可视化引起的节水效应的研究仅在短期实验中对其进行了评估。在这里,我们表明,基于智能电表的消费反馈和数字用户参与干预所促进的节水行为可能会长期持续。我们对西班牙巴伦西亚的334户家庭进行了分析。我们发现,与预处理之前的观察相比,参与我们的节水计划的家庭中,有约47%的家庭长期减少了8%的用水量。自该计划开始以来,节水行为持续了两年多,特别是对于那些每天都收到智能电表信息的家庭。我们的结果提供了经验证据,表明基于智能电表的耗水量反馈和数字用户参与可以有效地促进持久的保护行为。
