About Waterflow

A 100% New Zealand  owned Family business that cares

Waterflow Logo

We are the manufacturers of the Naturalflow and Econotreat Wastewater Treatment Systems. It all began back in 2006 when we got into Naturalflow Systems, a fledgling product that has been developed and refined to the robust range of systems we now offer to the market. In 2010 the company name was changed to Waterflow NZ Ltd and the Naturalflow name remained as the product brand name, allowing us to add more services to our offering while retaining Naturalflow as a wastewater system; this saw us selling and installing whole projects, including wastewater, stormwater and drainage.

There have been many significant milestones along the journey, with the most notable being the recent acquisition of Waipapa Tanks in 2021. This added the Econotreat systems to our offering, and immersed us in a steep learning curve of pre-casting concrete tanks. With tightening regulations throughout the country, the Econotreat systems has risen to the challenge; having a National Certification they have allowed us to serve our clients in more sensitive locations with stringent requirements.

If you are building rural, we have the answers, nothing to big or too small.

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


“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.
