Innovation based on experience
We support forward-thinking global clients using our comprehensive understanding of wastewater heat recovery (WHR).
From owning and operating the UK’s first commercial WHR system to completing detailed feasibility studies for global WHR projects, our knowledge and experience is shaping the low-carbon future of heating and cooling.

Since 2019, we have owned and operated the WHR system at Borders College in Galashiels – the first commercial system of its kind in the United Kingdom. Commissioned in 2015, the system comprises a 500m heat network that supplies up to 800kW of heat to the site’s five boiler rooms.
We completed a feasibility study assessing viability of WHR as a low-carbon heating solution for the Worthing Civic Quarter Heat Network (WCQHN). Once complete, the WCQHN scheme aims to deliver heat into a newly-built district heat network responsible for heating nearly 30 public sector buildings in central Worthing.
Centrio, the largest core-competency district energy operator in North America, engaged us as the technical expert for a WHR scheme at Denver’s National Western Center – the largest sewer heat recovery project in North America. We were tasked with peer reviewing designs and providing advice based on our experience with WHR operations in the UK.
As part of a low carbon heat generation study, Max Fordham and Camden Borough Council commissioned us to complete a feasibility study assessing the viability of a WHR system that, once complete, will provide heat to a heating network serving the residents and community centre of the Maiden Lane and York Way Estate, London.
We acted as the technical expert advising McKinstry Construction on the design of Seattle's first WHR system. The system will abstract wastewater from a nearby 84 inch diameter municipal sewer and deliver heat to four residential and commercial buildings.
