What is the Ecoflo biofilter?
The Ecoflo biofilter is the most sustainable wastewater treatment system on the market thanks to its 100% natural, renewable, and compostable coco filter.
Whether you’re installing a new septic tank, upgrading an existing one, or looking for tertiary wastewater treatment, the Ecoflo biofilter offers a simple, compact, and energy-free solution.
Forget about the hassle of a drainage field — with Ecoflo, you can legally discharge effluent directly into the ground or a watercourse, all while complying with the General Binding Rules.

This system is ideal for:
- homes and rural holiday cottages
- singular and multiple glamping sites
- camping sites
- hotels
- stately homes and castles
- golf courses and off-grid sporting facilities
- off-grid locations
Why choose the Ecoflo biofilter?
In an effort to protect our watercourses, rivers, streams, ecosystems, and ultimately our planet, the UK is enacting stricter effluent standards for septic systems.
The Ecoflo biofilter offers distinct advantages depending on your needs and the type of septic system required on your property.
Combine it with a septic tank
The Ecoflo biofilter can receive effluent from your new septic tank and treat it according to regulations.
Even better, it can be used as a bolt-on option for existing septic tanks, helping you conform with the General Binding Rules without the hassle or expense of replacing your entire system or installing a new drainage field.
Drainage field | Ecoflo biofilter | |
Lifetime installation | No | Yes |
Low usage of garden space | No | Yes |
Designed to prevent blockages | No | Yes |
Effluent monitoring and sampling | No | Yes |
Warranty | No | Yes |
PIA certification | No | Yes |
Combine it with another sewage treatment plant
The Ecoflo biofilter is ideal for tertiary wastewater treatment. If you already have a sewage treatment plant, add the Ecoflo biofilter to elevate your system's overall treatment performance.
It removes suspended solids and other pollutants from effluent, giving you a highly effective solution that is future-proof if stricter standards are introduced later.
How does the Ecoflo biofilter work?
The Ecoflo system filters wastewater through all-natural coconut husk fragments. No energy is required for treatment, making this sewage treatment plant the sustainable and economical system of choice.
Step 1: Wastewater inflow
Wastewater flows from your septic tank or existing sewage treatment plant into the Ecoflo biofilter for additional treatment.
Step 2: Non-mechanical tipping bucket
Inside the Ecoflo biofilter, a non-mechanical tipping bucket scatters wastewater across perforated distribution plates. These plates allow wastewater to evenly trickle across the coco filter.
Step 3: Coco filter
The coco filter is the heart of the Ecoflo biofilter. It creates a physical treatment barrier that cleans effluent to an even higher standard.
Step 4: Final discharge
After percolating through the all-natural coco filter, wastewater is safely discharged into the environment.
