Yorkshire Water is to invest £30m in its waste water treatment works in Saltend, Hull to improve the site’s operation.
The work, which will begin in December, with completion late Autumn 2020, will help the firm produce more sludge.
Sludge is a bi-product of waste water treatment and the anaerobic digestion process produces bio-gas which is used to fuel a Combined Heat and Power engine which heats water for the process and generates electricity.
This electricity will be used to power the site and any surplus electricity will be transferred to the electricity grid.
Yorkshire Water is also looking at alternative uses of the bio-gas such as, after cleaning, injecting in to the gas grid to provide renewable energy to homes and businesses.
Yorkshire Water Senior Project Manager, Mike Smith, said: “We are delighted to announce this investment which will make a huge improvement to the performance of the site.
“This investment shows our commitment to invest in renewable energy and benefit the environment as we look at ways of becoming more efficient and self-sufficient and help keep customers’ bills low.”
The site will also have a new inlet works, which will make the site more resilient by giving the firm greater ability to remove unwanted items from the incoming waste water.
