Sludge Power for Riverside Treatment Works in Rainham, Essex, UK

WET News - THAMES WATER is planning to upgrade its sludge treatment facilities at Riverside Sewage Treatment Works in Rainham, Essex to run on renewable energy.

The plant will treat the solid waste left behind after the sewage treatment process and use it to power the entire site.

Nick Fawcett, project manager for Thames Water, said: "All the sludge which is currently produced at Riverside is pumped through an 8km underground pipe to Beckton Sewage Treatment Works where it is incinerated and used to generate renewable energy to power that site.

"However, because of population growth in the area and proposals to extend the treatment works at Beckton - which will inevitably produce more solid waste - we now need to have better facilities to fully treat waste at Riverside. We are planning to digest sludge on site, using anaerobic digestion."

Subject to approval, construction will begin in early 2009, and end by 2010.
