  I haven’t manage to go to sewers very often – I mostly go the treatment plants (where the sewers end up) but the strangest/grossest thing I’ve ever seen is a FATBURG! They are HUGE balls of fat and grease that can something get down the kitchen sink and build up in the sewers – they are very stinky and hard to remove!
