The increasing concern with the environment and specially with the use of the water resources resulted in the increasing valorization of the drinking water as well of consumption. Innumerable are the activities that use this resource, one of them, the Car Wash Station (CWS), object of this research. In Brazil, about 32,700 CWS approximately consume 3.7 millions of cubical meters of water per month that transform it in wastewater. In this context, this work had, as general objective, the development of alternative technology for wastewater treatment aiming the recovery of the water from car wash station. For so much, the methodology had as base seven main aspects: 1) diagnosis of the current situation around the activity of CWS; 2) characterization of the crude wastewater generated by CWS; 3) mathematical modeling to identify the critical factors of project; 4) development of the prototype; 5) researches of patents to verify the innovation; 6) elaboration of the process for patent request and 7) specifications of the criteria for development of installation and operation manuals of the wastewater treatment system. In the case of Toledo/PR city, from the 47,155 registered self-driven vehicles (of the whichonly 27% pass for CWS), with a medium consumption of 2682,5 m3 water per month, it was verified a generation of 2.921,14 m3 wastewater per month with highly variable characteristic, having only 97% of the CWS some treatment system. The inefficiency of the conventional systems was verified and the analysis resulted in the proposition/development of two technologies (patent request number MU8701195-6 23/07/2007 and number MU8701196-4 23/07/2007) having, among their characteristics, the low cost,installation/operation/maintenance easiness, need of little space, efficiency and versatile in application form. In this way, this work should intended to contribute with the minimization of the environmental problem around the activity of CWS
