Abstract

This paper carries out an evaluation of Brazilian services water supply and sanitary sewers in the years 2002, 2007 and 2012 based on the principles and guidelines of public governance. For this we used the methodology Data Envelopment Analysis (DEA) with guidance product, where it was the efficient frontier and the relative of service providers efficiency taking into account the use of public resources over the scope of services and financial performance before and after the implementation of the National Basic Sanitation Law - LNSB subsequently applied the Malmquist Index to analyze the dynamics of factor productivity between years, there was an improvement in productivity in all periods analyzed, however the period after LNSB showed less improvement over the previous period, a fact attributed to greater reduction of the pairing effect coupled with low growth in displacement effect. In addition there was less improved productivity in the aggregate period (2002-2012) than in the two other periods where despite having the greatest effect annealing of the intervals, we observed technological regression.
