A £72M sludge treatment facility which will generate enough renewable energy to power 8,000 homes has been given the go ahead by Leeds City Council.
Civil engineering firm Black & Veatch and Clugston Construction will deliver the anaerobic digestion facility at Knostrop waste water treatment works, which will be capable of processing 131t of dry sludge a day when it is complete in 2019.
It will contribute to a target of recycling 94% of the region’s sludge by 2020, and will offer renewable power production from the waste water effluent.
“This is the single biggest investment of our current investment period (2015-2020) and will not only provide increased treatment capacity for our sludges but will also deliver significant operational cost savings enabling us to keep customer bills as low as possible,” said director of asset management Nevil Muncaster.
“Knostrop is designated as a strategic waste site so by increasing the future sludge and bio-solid treatment capacity of the works the project will support also growth in the Leeds sub-regions.”
The new facility will provide 55% of the site’s energy needs and is expected to result in a 15% drop in carbon emissions across the company.
It will replace the existing sludge and bio-solid incinerator which was constructed in 1993, although the Knostrop waste water treatment works has been treating sewage for around 100 years.
