    The purpose of this work is to design a system to improve the conditions of wastewater from car washers in Ambato City. There is currently a cadastre of 61 establishments dedicated to the washing and lubrication of cars for which a field and experimental research of 10 washing machines is carried out to determine the volume of entry and exit (generated in the washing process), of three types of vehicles (cars, trucks, 4 * 4); a design flow rate of 3 l / min was obtained. Wastewater from car washers was analyzed in the laboratory of the Faculty of Civil and Mechanical Engineering of the Technical University of Ambato, and the result is that the contaminated effluents exceed the maximum permissible limits of the Unified Text of the Secondary Legislation of the Ministry of the Environment (TULSMA), with the exception of settleable solids, with average values of 864 mg / l for COD, 432 mg / l for BOD5, 1533.34 mg / l for oils and grease, 2355.56 mg / l for total solids. Through bibliographic research, it was determined that the treatment processes with the most efficient in reducing contamination, are the implementation of screening or grids, primary sedimentation, grease trap and filtration. The filtering materials were chosen according to theses made by students of the Faculty of Civil and Mechanical Engineering of the Technical University of Ambato, with the best conditions for filtering, peat, volcanic pyroclastic and activated carbon were used as optimal materials. The construction of the treatment system in simple concrete and masonry is proposed with a cost of 2578.88 US dollars.
