Abstract: A company is using tap water previously demineralised for their productive process. Now, is considering the possibility of demineralize the water from the wastewater treatment plant (WWTP), that is currently spilt onto the sewage system (SS), and the water from two wells and use them in the process in order to reduce the consumption of tap water and the cost the use of it involves. The aim of this project is to plan the closing of the water cycle (production-WWPT-production) and verify if it’s profitable, which means, check if the initial investment will be amortized and, what’s more if the project will suppose an economic saving in a long-term. This project has been realised taking in account the only two premises that the company has imposed. The first one is the initial investment of the project has to be minimum and the second is the new installation has to require the minimum maintenance and attention of plant’s operators. According to these premises, the process designed for achieve the aim of the project consists on a vessel, a filter and a pump. Finally, the initial investment of 25,000 € is returned in 2.5 years and the company will save 11,000 € per year
