It describes some of the treatment systems that make possible the recirculation of the effluent deriving from car wash, citing its stages, used processes, advantages and disadvantages. There are some technical information about the implamentation, functioning and maintenance of systems of reuse, observed in technical inspections to a company of transport of passengers and to some ranks of car wash stations, located in the city of Sao Paulo.
