In this section you will find lots of information about how and where Yorkshire Water produces and treats sewage sludge.
Yorkshire Water is embracing the sludge treatment market as part of an industry-wide effort to drive efficiency, boost resilience and deliver further innovation within the water sector.
The sludge treatment, or bioresources market as it is also known, is estimated to be worth up to £1.6bn in the UK.
Yorkshire Water currently spends around 10% of its annual operating costs treating sludge, this has recently increased as it continues to recover from the Boxing Day floods of 2015. We now plan to offer more opportunities for third-party companies to enhance how it transports, treats and recycles sludge.
Around 150,000 tonnes of sewage sludge are treated each year by Yorkshire Water, with 69 per cent converted into renewable energy through a process known as anaerobic digestion (this will be 100 per cent in 2020).
The renewable energy benefits of sludge treatment is helping us keep costs down for customers. We have continued to invest in anaerobic digestion in a move which will deliver significantly lower operating costs by 2020.
Yorkshire Water has 11 key anaerobic digester plants across the region treating sludge converting it into a fertiliser and also creating a biogas that is then turned into green electricity. This is then used to provide the power to operate our sewage treatment works.
The water industry regulator, Ofwat, has requested that water companies voluntarily share bioresources market information by November 2017. Water companies must publish this information annually from July 2018. Information for interested parties can be found on the links on the right hand side of this page.
We hope that this helps you to understand the scale and details of our operations and encourage organisations who might be interested working with us in this area to get in touch:
