ALGAESYS in the UK: Proven Municipal Wastewater Treatment in Action
When it comes to innovative wastewater treatment technologies, proof of performance matters. That's why the ALGAESYS municipal wastewater treatment plant at Bolnhurst Water Recycling Centre (WRC) in Bedfordshire, United Kingdom, represents an important milestone for the company globally. Developed in partnership with Anglian Water's @one Alliance, the Bolnhurst facility has moved beyond construction and commissioning and is now operating as a municipal wastewater treatment plant, demonstrating the real-world application of ALGAESYS' algae-based treatment technology.
The facility was designed to treat municipal wastewater using a nature-based approach that combines engineering with biological treatment processes. Through the use of algae and other photosynthetic organisms as the primary treatment mechanism, the system is capable of removing organics, nutrients, pathogens and persistent pollutants while supporting resource recovery and substantial reductions in energy consumption and other operational costs, along with carbon emissions.
Inside the Bolnhurst WRC
For ALGAESYS Australia, the significance of the Bolnhurst project extends well beyond the UK. Across Australia, communities, developers and local authorities are facing many of the same challenges seen in the UK: ageing infrastructure, growing populations, tighter environmental regulations and increasing pressure on water resources.
The successful implementation of the Bolnhurst plant demonstrates that alternative wastewater treatment approaches can play a meaningful role in addressing these challenges. It provides a working example of how decentralised and scalable wastewater treatment systems can deliver high-quality treatment outcomes while reducing reliance on traditional approaches with their high asset management burdens.
Importantly, Bolnhurst showcases how algae-based treatment can be applied in a municipal setting: one of the most exigent environments for wastewater treatment.
The lessons learned through the implementation of the Bolnhurst facility align closely with the work ALGAESYS is undertaking in Australia, including at its Gingin site in Western Australia. Both projects share a common objective: delivering sustainable wastewater treatment solutions that employ natural biological processes while creating opportunities for water reuse and resource recovery.

Where the priority in Bolnhurst was delivering environmental benefits to sensitive bio-diverse chalk wetlands through ensuring high quality discharge, Gingin demonstrates how processedwastewater, recently approved for irrigation can also be a valuable resource that can contribute to healthier communities, improved water resilience and better environmental outcomes.
While each location has its own operational requirements and environmental conditions, the underlying philosophy remains the same: treating wastewater closer to its source, reducing environmental impacts and creating circular water solutions that benefit local communities.
The successful implementation at Bolnhurst is another example of ALGAESYS' growing international footprint across the United Kingdom, Europe, Australia and New Zealand. As communities around the world look for more sustainable approaches to wastewater management, projects such as Bolnhurst provide tangible evidence that nature-based treatment technologies can deliver municipal-scale outcomes while supporting broader environmental goals.
From Bedfordshire to Gingin, ALGAESYS continues to demonstrate that innovative wastewater treatment can be both practical, affordable and sustainable, while helping communities rethink what's possible in the future of water management.
