What is the primary purpose of measurement and verification in WUE programs?

• A. To forecast future population growth.
• B. To train new staff.
• C. To quantify actual water savings and verify program performance.
• D. To estimate project costs.

Answer: (C)

Measuring and verifying water use efficiency outcomes is about proving the actual savings and showing that a program is performing as intended. It involves establishing a baseline, collecting measurements before and after interventions, and applying a consistent method to isolate the program’s impact from factors like weather, seasonality, or changes in usage. By quantifying true water reductions and confirming that these savings persist, M&V provides credible evidence for stakeholders and helps guide decisions about program design, funding, and improvements. It isn’t about forecasting population growth, training new staff, or estimating project costs, which serve other purposes in planning and management.
