In this paper, four different solutions using nonwoven geotextile tubes are presented. On the first case, the tubes were used to replace slurry desiccation bays from mining. The new alternative increases the efficiency and the quality of the wastewater in the production process. Another case from mining is shown: a mining company that uses filter presses for dewatering sludge resulting from the iron ore processing was experiencing operational difficulties because the equipment required periodic maintenance. As an alternative solution for mining tailings dewatering during maintenance periods, avoiding the shutdown of the production process, the company adopted as a solution pumping the sludge directly to the geotextile tubes that drain and stock the material. The third case was a test performed at a water treatment plant. Currently, the sludge produced during treatment is sent directly to a sewage treatment plant. Thus, to avoid network overloading, as has been happening, solutions are being tested to choose the one with the best cost benefit. In this context, geotextile tubes were installed to evaluate the dewatering of the sludge with and without polymers. The last case is part of a municipal hydraulic revitalization project in Curitiba/Brazil, where a series of works were programmed to silting public parks lakes. In the first lake, the work has started by dredging the material accumulated on the bottom of it. Geotextile tubes were installed on site to receive dredging. Thus, it was possible to retain the sandy fraction responsible for the silting of the lake inside the geotextiles and to drain it, returning the dredged water back to the lake, without disturbing people who go to the park.
