RENEWABLE ENERGY GROUP CALLS FOR WASTEWATER HEAT TO BE USED
15th June 2017
Scotland’s sewers contain enough heat to warm a city the size of Glasgow for more than four months a year, according to figures by a renewable energy group.
A total of 921 million litres of wastewater and sewage – enough to fill 360 Olympic swimming pools – are flushed down toilets and plugholes in Scotland every day.
Capturing warmth contained in discarded water could prevent more than 10,000 tonnes of harmful CO2 entering the atmosphere every year, new analysis has claimed.
Statistics produced by Scottish Water Horizons for Scottish Renewables show how technologies such as heat pumps and wastewater recovery systems could harness that energy potential.
Renewable energy experts said water in UK sewers can be as warm as 21C (69.8F) and maintains a constant temperature throughout the year which “could heat a city the size of Glasgow” over a four-month period.
