The water company is looking to more than double the size of the ‘fat vat’ scheme, which has been running in Bradford since March.
A total of 85 residents in the Bradford Moor area signed up to the initiative which asks people to collect used cooking oil in 5 litre containers rather than pouring it down the drain.
Since then, more than 500 litres of used cooking oil have been collected and converted into biofuel and the area, which has previously experienced more than 80 sewerage blockages in the past five years, has not suffered a single blockage.
Yorkshire Water is now looking to expand the project to another 50 houses on nearby Byron Street.
Duncan Woodhead, network protection technician at Yorkshire Water, said: “The response from the local community to this trial has been excellent and people really do understand the difference they can make by changing their behaviour.
“We’ve been delighted with the amount of liquid we’ve managed to collect already and are looking forward to offering this to more people, which will help us generate more renewable energy and further reduce the amount of fats, oils and greases entering our network.”
