This research studies the effect of the presence of Sanitation Regulatory Agencies on the efficiency of the provision of water supply and sanitary sewage services in Brazil. For this, we used the Data Envelopment Analysis (DEA) methodology applied to data from the National Sanitation Information System (SNIS), of the Ministry of Regional Development (MDR) for the years 2015 to 2019, supported by the Jackstrap technique identification of outliers. From the DEA scores, a 2nd stage analysis is carried out in order to infer whether regulation and other external factors, such as: nature of the concession, regional location and population density, affect the efficiency measures obtained. The results indicated that municipalities where there is a private concession in at least one of the services tend to be more efficient. This same positive trend of efficiency was verified for population density, in which large urban centers are more efficient than smaller and more dispersed ones. The presence of Public Service Regulatory Agencies did not result in a positive trend in the calculated efficiencies. Thus, it is inferred that regulation in the country may be generating costs that are not yet reverted in an adequate proportion in terms of efficiency in the provision of water supply and sanitary sewage services.
