The present study aimed to evaluate the municipal management efficiency of water supply and sanitation using the approach of Data Envelopment Analysis. We evaluated 53 municipalities' service providers of potable water supply and sanitation, as definitions of Law 11.445/2007, with resident population between 50 thousand and 100 thousand inhabitants and from the sample of the National Information on Sanitation. Were used 33 indicators to evaluate the performance whose the results were transformed into dimensionless measures the interval [0, 1]. Of the total sample, nine services potable water supply and three sanitation obtained evaluation with index equal 1 and efficient classification, and the others had a lower valuation, in other words, lower than 1 and inefficient ranking. In the aggregate evaluation of the management sanitation (water supply and sanitation), only one municipality had efficiency classification.
