Key Metrics for Evaluation

To determinate whether a water conservation ampagign is suffeeding, evaluators typically track a handful of core metrics. Each metric sheds light on a different dimension of impact.

This is of ten calculated by comparang agregate water use before, during, and after the campeign, ideally againtt a control group that did not receive the intervention. Reductions can be reportted in absolute terms (gallons or lites saved) or per capa.

Challenges in Evaluation

Even with good metrics and methods, evaluators face persistent tustracles that can undermine results.

Data Accuracy and Consistency

Meter misseads, billing cycles that do not align with campeign timing, or missing data for rental accesties can introde noise. Self- reported secory data is subject to social desiability bias and faulty memory. To address this, cross- validate multiple sources: compare self-reported shower times with smart meter data, or audit a subset of rebated fixtures.

Bect Practices for Desigling Effective Evaluations

Toavoid common pitfalls and maximize learning, aquategn manageers should embed evaluation into their programme design from day one.

Agrish Baseline Data Early

Gather at leatt 12 months of pre- campaign water use data, along with baseline getys of awreness and behavior. This allows you to control for pre- existing trends.

Zahrnout controll or comparaison Group

Even a simplere comparasin with a similar untreated sousedhood contriens attribution. Whenever possible, randomize which areas receive thee campeign. If randomization is impossible, use statistical matching to create a catterble contrafaktual.

Plan for Longinal Follow- up
