Biogas will be supplied by a pioneering system by 2011.

Waste water sludge will be used to produce bio gas within two years.  The new plant at Davyhulme should produce enough gas to supply 500 homes in Manchester.


National grid and United Utilities who have begun work on a pioneering project centred on the Davyhulme wastewater treatment works.  Under the £4.3 million pilot scheme, anaerobic digestion will be used to produce bio methane for injection into the local gas grid and as fuel for a fleet of sludge tankers.


The bio gas will be treated to remove carbon dioxide and race elements.  Before being released into the gas distribution system the bio gas will be conditioned with propane and odorants.
