The present invention consists of a device consisting of a hollow membrane cylinder (1) that enters, like a plug, into a hole of a tank containing sewage. Said device is equipped, on its inner portion, with a membrane (3) easy to break, so that by pressing a nozzle, or other element, onto said membrane (3), it tears, so making the water contained into the tank easily flow out. The nozzle that breaks the membrane is hollow and connected to a collecting bag, therefore the water flows into the bag hygienically and preventing the operator to enter into direct contact with it. <IMAGE>
