摘要：Water treatment and its reuse process has gaining space specially in large urban centers where scarcity represents high investments and running costs for water harvesting and abduction at large distances. The present article describes how the civil construction industries realize the water treatment and its reuse process applied in their production. The aim of this article is to make the industries aware to treat and to reuse water present in their production through decantation, a viable and very much used resource currently assumed by companies. The methods and techniques employed in the research field were: documental analysis, interview and direct observation where collected and analyzed data were tabulated and reviewed in several sectors of the company as: management, supervision, management of quality and production laboratory. The results consisted on conscious consumption of water, in most rigorous controls to the means used in its treatment and reuse. By adopting that treatment and reuse management process the company will save around 70% to 80% of that water reuse and a saving in the energy bill since the new technology that is applied in the processes of decantation will guarantee a good quality water with low energy consumption bringing economic, social and environmental benefits.
