Public Water Point Coverage (PI3218)

This metric is intended to capture the number of people in a given coverage region who have access to water primarily through public water points.

Service coverage is a key indicator for water service providers (see aligned IBNET indicator 1.3).

The need to estimate the population served by public water points may affect the confidence that can be placed on the service coverage measure. The WHO Global Water Supply and Sanitation Assessment 2000 defined reasonable access as “the availability of at least 20 litres per person per day from a source within one kilometer of the user’s dwelling.” Water.org recommends that organizations use "population within 250m of a public water point" as the underlying definition for this metric.

This metric may help describe the HOW MUCH Scale dimension, which helps estimate the number of the targeted stakeholders experiencing the outcome. 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. The selection of metrics to measure and describe the five dimensions should be based on best practice and evidence.
