A descriptive social norm intervention using neighborhood comparisons reduces average water consumption in the first two postintervention months by 4.9 percent relative to the control group, while a planning postcard intervention reduces consumption by 4.8 percent. A descriptive social norm intervention using a town-level comparison also reduces water consumption by 3.2 percent, but this effect is not statistically significant. Finally, the study's one-time interventions continue to generate statistically significant reductions in water use for up to four months after they are implemented.CC BY-NC-ND 3.0 IGOWATER CONSERVATIONWATER UTILITYSOCIAL NORMSBEHAVIORAL ECONOMICSJournal ArticleWorld Bank10.1596/36718
