United Utilities, Davyhulme WWTW, CHP Plant


At the Davyhulme wastewater treatment works (WWTW) in Greater Manchester, United Utilities is generating renewable energy from sewage gas that is created from sludge left behind after the treatment of wastewater. United Utilities spent £100 million on the programme that leaves the sludge behind to be used to power the site. At the site 90,000 tonnes of sludge is being processed a year. Clarke Energy has supplied 2 new GE’s Jenbacher JMS620 GS-BL gas engines and re-located 3 x JMS620 GS-BL existing engines to Davyhulme for this project, together creating 12.0MW of renewable power. This is the equivalent of powering over 10,000 typical UK homes.
