  • No, some houses in rural locations will have a septic tank or something similar which needs to be emptied on a regular basis. The waste is taken to a local treatment works where it is safely processed, and can be used to generate clean energy, or fertilise land.

  • When you flush the loo or empty the sink, or put anything down the drain, this wastewater, along with rainwater from gutters and road drains, runs into the sewer. It flows to a nearby wastewater treatment works where it is processed so the water can be separated, treated and safely discharged back into rivers and the sea. The solids that are separated (called sludge) are increasingly used to generate energy or converted in to fertiliser.

    It is so important that the only things to go down your loo are the three 'Ps' - poo, pee and paper. Anything else, for example wet wipes or sanitary items, block the sewers and cause flooding which is a horrible experience. See our page on sewer flooding for more.
