Pumps oxygenate the sewage water at Daveyhulme waste water treatment works in Manchester, UK. United Utilities Daveyhulme plant process's all of Manchester sewage and deals with 714 million litres a day. The sewage sludge from the plant is put in huge biodigesters which produce biogas from the human waste. This biogas is 70% methane a potent greenhouse gas that is more than 20 times efficient as a greenhouse gas than C02. The biogas is burnt on site in a heat and pwer plant, preventing its release into the atmosphere. The plant generates around 7 megawatt of electricity per day from the renewable biogas.
