Water Savings from Services Sold (PI2884)

This metric is intended to capture the water savings to consumers from their purchase of the organization’s water-conservation offerings. For example, an organization that helps identify products and methods that conserve water (such as low-flow products, rain-collection devices, irrigation timers, or leak correctors) would report the total water savings to its clients resulting from these provided services.

Organizations should take care to use the same reporting period for both the number of clients and the average water savings per client.

In some contexts, this metric can serve as an indicator of whether the outcome being sought by an investor or organization is occurring (the WHAT dimension of impact). For more on the alignment of IRIS metrics to the five dimensions of impact, see IRIS+ and the Five Dimensions of Impact (https://iris.thegiin.org/document/iris-and-the-five-dimensions/). No single metric is sufficient to understand an impact; rather, metrics are selected as a set across all dimensions of impact. When possible, the selection of metrics to measure and describe the five dimensions should be based on best practice and evidence.
