Sewage system of Helsinki is under threat of mobile phones drowned in lavatory pans. Amount of mobile phones which end their life in sewage system increases in capital of Finland and its suburbs. It is impossible to say if these incidents are accidental or made on purpose. At refinery in Viikinmaki, Finland, thousand tons (200 full trucks) of solid wastes are collected annually. Besides mobile phones dentures, toys, cameras, torches are found. These things are hard to remove and they cause obstructions in sewage systems.
