Resumen
Water utilities provide water and sanitation services in monopolistic conditions. Hence,
assessing their performance through benchmarking is crucial for proper regulation. This
research addresses the limitations of self-evaluation Data Envelopment Analysis (DEA)
models commonly used for benchmarking water utilities’ efficiency. Given that these mod-
els often lead to overestimated efficiency scores, our study introduces a cross-efficiency
analysis framework integrating both self and peer-evaluation perspectives. This innovative
approach, applied to a representative sample of Chilean water utilities, uniquely consid-
ers unplanned water supply interruptions and sewerage blockages as undesirable outputs,
emphasizing service continuity. Average techno-economic efficiency scores based on self-
evaluation, and peer-evaluation were 0.681 and 0.388, respectively. Hence, significant
techno-economic efficiency overestimations in self-evaluation scores are evident, with
implications for regulatory challenges and potential service quality compromises. The
data also highlights a considerable opportunity for improvement in water and sanitation
continuity in Chilean water utilities. The findings not only shine a spotlight on the inherent
biases of prevalent benchmarking techniques but also highlight a substantial avenue for
bolstering water and sanitation service continuity within water utilities.
