Water utilities in low-income countries operate in an accountability vacuum: no standardized performance data, no public comparisons, no link between efficiency and access to financing.

The Utility Efficiency Index creates a global public scorecard covering five dimensions — NRW rate, cost recovery ratio, service continuity (hours per day), connection rate, and customer complaint resolution time.

Utilities are scored annually, results are published openly, and UEI scores are integrated into MDB and development finance institution loan eligibility criteria: a utility above a threshold UEI score qualifies for concessional financing; below it, financing requires a performance improvement plan.

The index creates three simultaneous incentives: government pressure to improve publicly visible scores, utility management motivation to hit financing eligibility thresholds, and civil society tools to hold utilities accountable with data rather than anecdote.
