Our Solutions


Recognising its significant contribution to the UK’s carbon footprint, the water industry has committed to a target of net zero emissions by 2030.

Delivering on this commitment will require carbon impacts to be factored into all current and future decision making. Innovative, sustainable wastewater treatment solutions are urgently needed to meet the net zero challenge; a challenge that is particularly tough in today’s regulatory climate of increasing discharge constraints.

PWS products and processes are a powerful example of the kind of integrated solutions that are needed. We help deliver net carbon savings at the same time as significantly higher quality discharges to meet today’s tougher consent limits.

Our technologies create a fraction of the emissions of traditional wastewater treatment processes. Our unique sludge treatment processes also make a significant contribution to achieving net zero carbon through reduced energy use, reduced sludge volumes, smaller footprint, lower treatment and transportation costs and enhanced energy recovery opportunity.
