Why our Bio-Bubble STP Surpasses BS-EN-12566 Standards

At the heart of our work is a commitment to excellence and sustainability. The Bio-Bubble treatment plant is designed not only to meet industry expectations but to surpass the BS-EN-12566 standard. This European benchmark sets requirements for small wastewater treatment systems, but our technology goes far beyond those minimum thresholds.

Exceeding Standards
The Bio-Bubble incorporates advanced engineering and innovative design features that deliver higher efficiency, reliability, and environmental protection than the BS-EN-12566 standard requires.

Our systems are built to achieve superior treatment performance, ensuring cleaner discharge and a reduced ecological footprint.

Every plant is constructed with durability and long-term resilience in mind, offering peace of mind for decades of operation.

Why Testing Isn’t Applicable
Unlike mass-produced systems, the Bio-Bubble is a bespoke solution. Each plant is individually designed and built to suit the specific site, flow rates, and customer requirements. Because of this tailored approach:

It is not possible to send a Bio-Bubble unit off for standardized laboratory testing.

No two plants are identical, meaning the conventional “one-size-fits-all” certification process does not reflect the true performance of our installations.

Instead, our assurance comes from proven engineering principles, rigorous in-house quality control, and the consistent track record of successful installations across diverse environments.

Recognised and Approved
Importantly, the Environment Agency (EA) is fully aware of this bespoke approach and has approved the Bio-Bubble system for installation at 100’s of sites across the country. In addition, many local council planning departments have also recognised and approved our technology, giving customers confidence that our plants meet regulatory expectations.

Our Promise
Choosing a Bio-Bubble STP means choosing a system that is engineered to exceed expectations. While the BS-EN-12566 standard provides a baseline, our bespoke design philosophy ensures that every plant is optimised for maximum performance, environmental responsibility, and customer satisfaction.
