What is the Ecoflo septic system?


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.

Why is the Ecoflo biofilter sustainable?

From production and shipping to installation, maintenance, and usage, the Ecoflo biofilter has the lowest carbon footprint of any comparable product on the market  and the numbers to prove it.

Table Total carbon footprint after 50 years

1. Based on analyses of septic installations in Pennsylvania.
2. Systems installed in very-low-permeability soil and rated for four-bedroom homes.
3. Distances between installations and required materials assumed to be 40 miles for filtration sand and stone, 20 miles for backfill.
4. Ecoflo biofilter installations include final dispersal to at-grade bed.

How does the Ecoflo biofilter 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.
