efficiency of public utility enterprises under state ownership or local government jurisdiction, such as cities and municipalities. These enterprises
are tasked with delivering high-quality public services to citizens at affordable prices. Achieving this goal necessitates efficient management and
judicious use of public resources. The research evaluated the efficiency of public water utility enterprises in the Federation of Bosnia and Herzegovina
using the Data Envelopment Analysis method. Three indicators were used as inputs in the model: asset value, number of employees, and total expenses. The
output indicator was total revenue, which reflects the number of users under relatively uniform service tariffs. The findings reveal that 92.31% of
these public utilities exhibit technical efficiency levels above 90%. Additionally, 53.85% demonstrate 100% technical efficiency in input utilisation.
The results highlight enterprises that inefficiently use assets incur above-average costs or employ more workers than necessary. The study concludes
that the Data Envelopment Analysis model effectively identifies state-owned public utility enterprises that consume above-average resources to deliver
the same scope and quality of services. KEY WORDS CLASSIFICATION
