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.


The Ecoflo biofilter is most often a solution for:

  • primary residences
  • seasonal cottages
  • residential developments
  • apartment buildings
  • campgrounds and parks
  • office buildings
  • schools
  • temporary work camps


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 Québec.
2. Systems installed in low-permeability soil and rated for three-bedroom homes.
3. Distances between installations and required materials assumed to be 60 km for filtration sand and stone, 33 km for backfill.
4. Ecoflo biofilter installations include Premier Tech compact sand filter.

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.

How much does the Ecoflo septic system cost?

When we share the price of the Ecoflo septic system, we refer to the total cost of the project.

The total project cost includes more than just the Ecoflo biofilter. It includes the septic tank, septic drain field, and other expenses that would be added to any septic system budget, such as:

  • soil tests
  • system design
  • permits
  • materials
  • installation
  • labour

The cost does not include tertiary treatment technologies that may be required by regulations in your area.

Total project costs for simple sites

The simplest sites have large surface areas, easy access, permeable soils, and flat ground.

To estimate the total cost of a project on a simple site, let's assume that you choose one of the most popular Ecoflo biofilter models in Canada: the polyethylene unit for a three-bedroom home.

Province New construction System replacement
Alberta $25,000 - $30,000 $25,000 - $30,000
British Columbia $20,000 - $25,000 $20,000 - $25,000
Ontario $22,000 - $26,000 $24,000 - $32,000
Québec $13,000 - $16,000 $13,500 - $16,500


Total project costs for difficult sites

Complex sites may have small surface areas, limited access, shallow or slow-draining soils, or steep slopes.

These factors make it more difficult to move wastewater downstream and return it to the environment. Extra materials and longer installation times may be needed to overcome these challenges.

To estimate the total cost of a project on a difficult site, let's assume again that you choose the polyethylene Ecoflo biofilter for a three-bedroom home.

Province New construction System replacement
Alberta $30,000 - $40,000 $30,000 - $40,000
British Columbia $25,000 - $30,000 $25,000 - $30,000
Ontario $28,000 - $36,000 $30,000 - $38,000
Québec $14,500 - $16,000 $15,000 - $22,000
