Specialising in biological wastewater recycling using the biomimicry-based and pond-looking TreeWell system.

A paradigm shift in how wastewater is treated and reused. Be smart with water.

We offer property developers and owners the opportunity to reduce water bills and ensure water resilience, without any capital cost. We do this by delivering a wastewater recycling service, powered by TreeWell, a biomimetic system that treats water for use in irrigation, sanitation or air conditioning.

Sludge-free and low maintenance. All sludge is absorbed as nutrition by microbes and plants in the tank, leaving only minerals in the treated water.

Compact in size. One system of two tanks treats 25kl of water a day, taking up as little as 9m2 surface area.

Aesthetically sound. Selected plants placed in the secondary and only visible treatment tank creates a garden-like feature.

A wastewater recycling service? 

Yes. We simply install the TreeWell at zero capital cost and bill for the service on a pay per use basis, at a discount to municipal rates = lower costs, a more resilient site and a green building. Find out how it can benefit your site.

How does it work?

TreeWell is a biomimetic wastewater treatment system that optimises and condenses natural processes of decomposition and metabolism to treat wastewater. A standard module consists of two tanks, one aerobic and one anaerobic, taking up as little as 9m2 surface area.

Step 1: Aerobic

Pollutants found in the wastewater are broken down and metabolised by microbes, which are then in turn consumed by larger organisms in the constructed microbial ‘food web’. This process continues up the trophic levels of the constructed ecosystem, until small insect larvae in the roof of the second tank allow biomass to exit the system.

Step 2: Anaerobic

The second tank is open, with plants growing in the roof. The plants absorb some of the pollutants contained in the wastewater as well as the plant root zone providing optimum conditions for the microbial interactions which drive the system to take place.

Step 3: Clean water

The use of these biological processes allows for a treatment which leaves no residual sludge – unlike practically all other wastewater treatment systems. As a result, the TreeWell has a very low maintenance burden. The system can be customised to treat water from different waste flows and to meet requirements for discharged water.

Core component 1: Tanks

These are specially designed from a CE certified thermostatic polymer to optimise the flow conditions to emulate hydraulic patterns in wetlands.

Core component 2: Plants

Plants are drawn from widely distributed families of flora typically found in wetlands. They can be sourced from nurseries or directly from wetlands. No maintenance of the plant growth is required apart from for aesthetic reasons. Once the system is in operation the plant growth and decay will reach a homeostatic equillibreum.

Core component 3: Microbes

This includes a specially selected mix of microbes which metabolise waste components in sewage and nematodes, cilliates and other protozoa. The microbes included are cosmopolitan, meaning that they are found in most regions of the world and do not present a risk of environmental contamination. The insects referred to above which feed on the microrganisms at higher trophic levels are small aquatic insects, as opposed to flies or mosquitoes .

Core component 4: Mechanical

The system contains one sewage pump and one aerator.

Current project in for Venda University in South Africa. 18 TreeWell tanks will treat wastewater from over 1000 people. Next step: install the plants in tank 2 and cover over tank 1.
