Metering and Submetering
A water meter is a device used to measure the amount of water consumed. The Alliance for Water Efficiency supports full metering of all urban water customers. Installing meters and billing according to usage is the single most effective water conservation measure a water utility can initiate. While many water purveyors are fully metered, there are a surprisingly large number of water providers with unmetered residential customers -- still charging customers flat rates -- even in water scarce regions of North America. As measured recently by utilities who have installed meters, unmetered water consumption can be reduced 15% to 30% when metering and commodity rates are implemented.
