Kelda Water Services and its sister company Yorkshire Water are supplying the council with the biogas, which is produced at their sewagetreatmentworks in Sheffield.
The scheme includes one kilometre of embankment and provides flood protection for Keadby Power Station, three sewagetreatmentworks, two railway lines and three stations, the A614, the A616 and the M18 motorway.
There is a strong suspicion that if this oestrogen is not removed during sewagetreatment (some works do, some do not), it causes serious damage to rivers and lakes.
