Birmingham - Minworth

Severn Trent owns and operates Minworth Sewage Treatment Works (STW), a site that aims to be one of the most sustainable and energy-efficient in the UK. It is Severn Trent's biggest sewage plant, treating wastewater from more than 1.6 million homes and businesses.  

Minworth commissioned Cambi's thermal hydrolysis process system in 2018 with the aim of increasing renewable energy production. The plant intended to become a source of sustainable energy for internal processes and the community.   

Minworth also takes an innovative approach towards nutrient recovery from sludge. Biosolids resulting from sludge treatment are pathogen-free, low-odour, and can be used as Class A biosolids fertiliser for application in agricultural land.  

Across the company we currently generate around 34% of all of the energy we use as a business, and the thermal hydrolysis process will move us closer to our target of making that 50%.
