Why Natural Flow?

No Power Required

Use the sustainable forces of nature to treat your water and save on power bills. Meaning there’s no power required during the treatment processes and on very flat sites a small pump is all that maybe needed to move the treated water from the NaturalFlow system to the Land Application Field.

Minimal Maintenance

NaturalFlow takes care of itself without constant monitoring and mechanical repairs, just like a natural ecosystem, giving you the chance to spend more time on the important areas in your life. You are assured of a robust, long-lasting system.

Why Natural Flow?

Modular System

The NaturalFlow is a modular system designed to suit your individual site needs. From primary through to secondary treatment, your system is designed for your specific site and your particular needs. With our expert Wastewater Engineers, you are assured of a system that works with optimal performance.

How It Works

Keeping it simple is our philosophy; using power free natural aerating processes, instead of mechanical pumps etc, to treat wastewater to advanced secondary levels.

Nature is one huge recycling mechanism, and the ‘NaturalFlow System’ works with ‘Nature’ by harnessing these forces, that have been quietly working together for thousands of years to break down and decompose waste all around us, and positioning them in an enclosed eco-system that simulates the forest floor, to treat and break down your wastewater until it is perfectly safe to be re-introduced into the environment, via the soil, and of course – ‘Nature’ does all this, for you, for FREE!

Septic Tank Alternative

One of the oldest and most basic approaches to treating sewage and wastewater is the classic septic tank. In this traditional system all your sewage and wastewater goes into one tank for separation. The solids then sink and settle to the bottom and the lighter oils etc float to the top to form a scum layer, a process that the ‘industry’ allows 24hrs to fully accomplish. The middle layer then contains the liquid component that is now ideally clear of solids and can be disposed of out to the soakage field.

The issues we experience with this approach is; as the solids and scum layers build up in the tank over time and the middle layer becomes narrower, the passage of wastewater through the tank is faster, so that the separation process is not fully completed and solids can get pushed out to your soakage field, resulting in the foul odours that septic tanks are famous for. The same thing happens when there’s a sudden influx (or shock loading) of sewage and wastewater into your tank (when the families around), and again the solids do not have time to separate and settle, resulting in solid matter (carry-over) passing through to the fields.

This then has a major impact on the soakage fields as the effluent with ‘carry-over’ from the septic tank causes ‘clogging’ or ‘creeping failure’ in the field which can cause pooling or even runoff. This can result in contamination and overflowing trenches, harmful to both humans and animals.

NaturalFlow presents an innovative septic tank alternative by solving these problems from the start. NaturalFlow’s approach separates the solids and liquid right at the beginning of the treatment process, reducing them down to harmless humus by way of vermiculture and other natural media processes. The liquid, now extremely free of contaminates, is furthered filtered before being returned to the environment.

Unlike septic tanks, which need to be pumped out every 3-5 years, NaturalFlow requires practically no system maintenance, while promising to operate at peak performance for years to come.

What Others Think

“Gee I love you guys :)”

I was called this morning from Rangi to say the 6-monthly inspection is being done at 2pm today.

Your guy doing it has been held up, so he actually called to let me know.
This is never happens normally with tradie type people.

If your company ever needs someone to sell your systems up this end of the woods then give me an interview.
After my experience with all your people, I would be proud to sell it!

What Others Think

“Easy”

“NaturalFlow system is such a basic and easy system to look after and operate. We are very pleased with it and are glad we went with the system. The grey water has certainly been great on the gardens and the black water bed once planted looks after itself. Great!”

What Others Think

“Looks after itself”

“Back in 2008 along with our building projects we decided to go for the NaturalFlow sewage system as it didn’t require any power, on our site. We have been very impressed with the performance of this system, with very little maintenance, it basically looks after itself.
Without hesitation I would recommend the NaturalFlow system to anyone as I have had no difficulties with product or the friendly team at Waterflow NZ Ltd.
