I heard a sewage treatment expert talking bout this on CNN (thanks to Finding Nemo) and he basically said that the fish would probably die within minutes inthe sewer, but i he did make it to the sewage plant, he would be shredded by the first stage of treatment, which is a huge spinning stack of blades, named (for unknown reasons) the "muffin grinder," that breaks solid waste into dust-sized particles.
