RESUMO

This work intends to maximize the rain water precipitation collection and use it in the gardens and sanitaries besides the production process of the TDI unit in Camaçari, Bahia of the Dow Quimica. Due to the seasonality of the rain water, an storage tank becomes necessary if the usage in the production process will happen. Using the methodology to research and identify all the places where water is necessary with its respectively demands, besides all constructions and buildings where will be possible to collect the rain water with small changes and investment in the current layout of the company unit site, the following results were obtained: investment of R$ 352,991.00 for just all the changes which does not involve the condensate return to the steam provider and R$ 1,302,991.00 if all the changes will be included. The Return of the Investment (ROI) for these two options above will be R$ 871,305.00 per year for the first case and R$ 2,298,845.00 per year for the second case. All two options will give an immediate and permanent return of the investment once implemented. This is classified as high attractive investment by the company. Another alternative would be to invest less initially and promote just small changes. In this case the investment would be R$251,419.00 and the ROI would be R$ 680,709.00 per year. This option is also very attractive. The final conclusion is that all the options showed will give a very good and quick environment and capital ROI. A reduction of more than two hundred thousand of water cubic meter per year and in all the years were estimated after the changes will be implemented.
