Resum:	In recent decades, the debate over the optimal mode of public service delivery has gained increasing relevance, particularly in the case of drinking water supply. This study offers a comparative analysis of the technical efficiency of direct and private management models, explicitly incorporating environmental factors as conditioning elements. A non-parametric order-m methodology based on the Free Disposal Hull (FDH) model is employed, enriched with conditional models, metafrontiers, and an order-m variant using simulation to mitigate the influence of outliers and strengthen the robustness of the results. Efficiency is estimated over a four-year period, allowing for the assessment of both average performance and adaptability. Findings indicate that, on average, direct management achieves higher levels of technical efficiency. However, private management exhibits greater adaptability to contextual changes, suggesting it may be more suitable in dynamic or complex environments. This research contributes to the ongoing discussion on public service efficiency and underscores the importance of accounting for environmental factors in service performance evaluations.
