Domestic Sewage and Wastewater Treatment Systems

NaturalFlow offers power-free, completely sustainable sewage and wastewater treatment systems for rural homes.

Ground-breaking Home Sewage Treatment Systems

NaturalFlow brings an innovative solution to common issues in home sewage systems. Treating grey water and black water separately, sewage treatment is ingeniously simplified, resulting in a quiet, odourless and smooth-running system.

From primary to secondary treatment, our home sewage systems are built to suit the requirements of your site and give you years of optimal performance with very little maintenance. Operating with power-free treatment processes, the NaturalFlow system can give you great savings from day one. Installation is available nationwide, and you can count on our team to deliver quality support on time, every time.

The NaturalFlow Difference

Aptly named, the NaturalFlow System harnesses free, natural processes to treat domestic sewage and wastewater. An enclosed ecosystem that mimics the forest floor is established to treat your wastewater until it is ready to be returned safely into the soil and environment.

Simply, the NaturalFlow system harnesses and utilises what has been proven effective in composting and decomposition over thousands of years: nature.

Features And Benefits

The NaturalFlow system takes New Zealand’s home sewage systems to a whole new level, providing homeowners with numerous benefits.

Power Free Treatment Processes

The NaturalFlow does not draw on any resources other than nature and operates quietly with no high-tech electronics or complicated mechanics. The system mimics nature, particularly the forest floor, to treat sewage water. With the help of Tiger worms and natural filtration processes, NaturalFlow utilises natural biological purification processes.

Cost-effective

NaturalFlow’s house sewage system offers great savings. Using the sustainable forces of nature, NaturalFlow requires no power to treat sewage and wastewater, helping you save on power bills. And with straight forward installation and minimal maintenance requirement, the NaturalFlow system is cost-effective from day one throughout its lifespan.

Low Maintenance

Just like a natural ecosystem, the NaturalFlow system takes care of itself without requiring constant monitoring and mechanical repairs. Owners simply need to conduct visual checks every so often and follow the dos and don’ts of owning a NaturalFlow system. This gives you the time to focus on more important areas in your life.

How It Works

NaturalFlow combines vermiculture with other natural settling processes to treat black water (from toilets and kitchens) and grey water (from showers and laundries). Depending on your wastewater disposal system, you can opt to have plants in your disposal field.

With the NaturalFlow system, the black water is separated from the grey water at its source, so there is no emulsifying of the solids with the bulk of the wastewater. Through this separation, the wastewater treatment process is greatly simplified and you convert solid waste into fertiliser. You can also have grey water re-use for non-potable uses.

With NaturalFlow, you have a home sewage treatment system that operates quietly and cost-effectively. Designing complete solutions, NaturalFlow can provide your home with a bespoke wastewater treatment system.

Treatment of Black Water

To treat black water, NaturalFlow uses a purpose-designed chamber called the WORMORATOR, which separates solids from the liquid and treats them by way of vermiculture and other power-free, natural processes.

The WORMORATOR is an enclosed ecosystem that mimics the forest floor and uses natural filter media’s that do not rely on any power source. Inside the chamber, a bark medium is used to filter out the liquid and retain solids. Tigerworms break down the residual solids and convert them into water-soluble nutrients. The liquid wastewater and nutrients are further purified and treated through natural media’s until they are safe to reintroduce into the soil.

Treatment of Grey Water

NaturalFlow offers a revolutionary sewage system for homes. Our system allows homeowners to reuse grey water. Having less solid waste than black water (water from toilets and sinks), grey water can be used to irrigate fields or landscaping. Separated from the black water, the grey water goes through a series of natural settling and filtering processes.

Final Disposal

After treatment, the grey water is combined with the black water for final disposal into the soil and into the environment.

Grey water carries minimal solids but has soap scum. NaturalFlow’s grey water treatment process quickly strips the grey water of scum to prevent putrefaction and the growth of anaerobic bacteria. In short, our system is safer for the environment and healthier for your home.

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.
