OFWAT Water Breakthrough Challenge

Transforming the Energy Balance of Wastewater Treatment

Wales AD Centre researchers are collaborating with water companies to demonstrate and evaluate a novel low temperature wastewater treatment process that not only drastically reduces the energy used to treat sewage, but also allows for the recovery of phosphorous and ammonia, and reduces the amount of surplus sludge produced. The result is a process with greatly reduced GHG emissions compared to current standard technology.

The project, which is led by Thames Water Utilities and also includes Dwr Cymru Cyfyngedig, South West Water Limited, United Utilities Water Limited, Scottish Water, Northumbrian Water Limited, Yorkshire Water Services Limited, Southern Water Services Limited, Uisce √Čireann and Severn Trent Water Limited will demonstrate the process using an industrial pilot plant at two wastewater treatment plants. The Wales AD Centre will be providing laboratory based support to assist the team with specifying and demonstrating the nutrient recovery aspect of the process, as well as providing academic expertise in the performance and evaluation of anaerobic wastewater treatment.

The project is funded by OFWAT and is expected to be completed in 2026.
