What is the Ecoflo septic system?

Ecoflo PACK open

The Ecoflo biofilter is the most sustainable septic system available and the best way to protect your property and the environment for the future.

This energy-free treatment system gently removes wastewater pollutants with a filter made of coconut husk fragments or a combination of coco and peat moss. Both materials are natural and compostable, and coco is 100% renewable.


The Ecoflo biofilter offers many advantages over other septic systems:

  • fast and easy to install
  • up to 50% smaller than other systems
  • never damages your landscaping
  • no full-system replacements
  • maintains selling value of your property

Why is the Ecoflo biofilter sustainable?

How does the Ecoflo septic system work?


Wastewater first flows into a septic tank. Solids settle on the bottom of the tank and liquids flow into the Ecoflo biofilter for treatment.

Inside the Ecoflo biofilter, a non-mechanical tipping bucket scatters wastewater across perforated distribution plates. Wastewater drips through these plates and falls across a filter made of coconut husk fragments or a combination of coco and peat moss.

This filter is the heart of the Ecoflo septic system. It creates a physical barrier that captures and removes wastewater pollutants.

After percolating through the all-natural filter, wastewater flows downstream for additional treatment or for safe discharge into the environment.
