Analysis of the energy efficiency guidelines contained in the Brazilian norms used in the sanitary sewage pumping station (EEE) project. The research was developed in three stages. Initially, a bibliographic review was carried out, with an analytical character, of the design and component parts of EEE. In step II, the standards of the Brazilian Association of Technical Standards (ABNT) related to the sanitary sewage system were identified, verifying the items with orientation of energy efficiency for the EEE project. In the last stage, the guidelines of sanitation companies for the elaboration of EEE projects were analyzed. It was found that the energy efficiency information is deficient in the 12 analyzed standards. Documents from sanitation companies were also identified to guide the preparation of EEE projects. With the research, it was found that designers need to evaluate the increase in the sewage detention time in the humid well, the installation of hydraulic and electrical parameters meters and the dimensioning of the EEE motor and pump assemblies, observing the peak hours established by the electricity sector. Among others. Thus, it is opportune to review and update NBR12208/1992 “Sanitary sewage pumping stations project-Procedure” and complementary norms, to provide recommendations that meet the technological evolution with the consideration of energy efficiency still in the design stage of the EEE.
