FOUNDING PRINCIPLES
Soil Microbiology
▪ Nature uses soil to purify water
▪ Nature uses microbes in the soil to process dead matter, this
is called decomposition
▪ Soil typically will buffer water to a neutral pH
▪ Soil bio-technology consumes very little energy and produces oxygen
▪ Bacteria in the soils help to destroy organics which may be contained
in the effluent
▪ Soil filters are optimised to significantly reduce nutrient/pollution loads
▪ Combined with plantings will release large amounts of water into the
atmosphere through transpiration
▪ Worms feed on bacteria and maintain the microbes of the soil
We do it simpler, Natures Way…
FOUNDING PRINCIPLES
Water Treatment
▪ Water cannot sustain dead matter
▪ There is no dead in water
▪ Anything that deceases in water will make its way to soil to be
de-composed
▪ Very costly to oxygenate to support aerobic bacteria

UNDERSTANDING
VERMICULTURE
The Mighty ‘Tiger Worm’…
The scientific name is Eisenia foetida, also known as Redworm,
Red Wiggler, Brandlings or Manure Worm
▪ The Tiger worm is an Epigeic worm, i.e. they live on the surface of the soil
▪ Closely related to the common earthworm but are much more aggressive
▪ Tiger Worms thrive in rotting vegetation, compost and manure
▪ Are usually found feasting on heaps of animal manure, rotting leaf mounds and
other organic materials that are on top of the soil
▪ Tiger Worms possess all the characteristics needed for composting and have proven
to be the most effective in the composting process
▪ The gut of the worm is teeming with bacteria and enzymes with which it digests its food
▪ Are capable of producing casings that are 100% natural

UNDERSTANDING
VERMICULTURE
The Mighty ‘Tiger Worm’ cont…
▪ Are able to dig deep into the soil (up to inches to be exact) allowing a more
loosened and aerated soil
▪ Consume half or even as much as their body mass daily, its weight being from
0.5 to 1 gram
Temperatures
▪ Tiger worms can easily tolerate temperatures from 3 to 27 degrees Celsius and will burrow
down to protect themselves, if needed.
▪ Natural Flow’s worms are bred in Cromwell where the temperatures
range from between, -7 – 38oC
Lifecycle of Tiger Worms
▪ Tigers take 53 to 76 days to reach sexual maturity and are bi-sexual
▪ The eggs take 2-3 weeks to hatch.
▪ As a guide, in ideal conditions, you can expect to double the
weight of your Tiger worm population in 3-4 months.
▪ 1 kg of adult worms would contain around 2,000 worms.

PLANTINGS & TRANSPIRATION
What is transpiration?
Transpiration is the process by which moisture is carried through
plants from roots to small pores on the underside of leaves, where
it changes to vapour and is released to the atmosphere.
Did you know?
▪ Up to 95% of the water absorbed by roots is lost via transpiration through
plant leaves
▪ 5% is retained by the plant for growth
▪ Studies have revealed that about 10 percent of the moisture found in the atmosphere
is released by plants through transpiration. The remaining 90 percent is mainly supplied
by evaporation from oceans, seas, and other bodies of water (lakes, rivers, streams)
▪ An acre of corn gives off about 3,000-4,000 gallons (11,400-15,100 litres) of water each
day, and a large oak tree can transpire 40,000 gallons (151,000 litres) per year
We do it simpler, Natures Way…
PLANTINGS & TRANSPIRATION
How fast does water move through plants?
Transpiration rates depend on two major factors: 1) the driving force for
water movement from the soil to the atmosphere and 2) the resistances to
water movement in the plant.
Driving force: The driving force for transpiration is the difference in water
potential between the soil and the atmosphere surrounding the plant.
The drier the air around the plant, the greater the driving force is for water to
move through the plant and the faster the transpiration rate
Breeze or air movement will greatly enhance transpiration
Accessing nutrients from the soil: The water that enters the root contains dissolved
nutrients vital to plant growth, like nitrates, ammonia etc.
It is thought that transpiration enhances nutrient uptake into plants.

HOW IT WORKS
GREY WATER MODULE
The grey water is separated at its source and
flows to the grey water module where it is
filtered through a matrix filter which retains soap
scum hair and fine particles and is disposed of
quickly to prevent petrification. Storing grey
water will only cause problems and unpleasant
odours.
WORMORATOR & DOSE MODULES
The black water is separated at its source and flows to
the WORMORATOR® module which mimics natures
most economical and efficient way to filtrate and
decompose solid matter.

INSTALLATION
▪ Waterflow NZ Ltd cares for it all!
▪ Waterflow NZ Ltd will facilitate this from the beginning to the end, starting with Certified
Natural Flow Installers to full completion sign off when install is complete
▪ All installations will be performed by an registered drainlayer and certified
Natural Flow System Installer
▪ All Installers are required to complete a Natural Flow System training course and will
be ‘Certified’ when they have completed this to the standard required
▪ All installers nationally will also receive ‘hands on’ installation training onsite before
they can become a certified ‘Natural Flow System Installer’
▪ All work carried out on any site must be done and completed in a professional manner
with diligence being shown to the last detail
We do it simpler, Natures Way…
INSTALLATION
▪ All installs to be signed of according to Waterflow NZ Ltd’s,
Installation Compliance Report and filed with Waterflow NZ,
Head Office, which will also be used to facilitate their
committal to a ‘culture of continuous improvement’
▪ All work undertaken by any of Natural Flow Installers must
be also in accord with the current regulations including the
NZ Building Code, AS/NZS 1547:2012 and all relevant local
government requirements
We do it simpler, Natures Way…
SYSTEM
MAINTENANCE
At Waterflow NZ Ltd we never advertise or teach that any wastewater treatment
system is a ‘set and forget’ – a culture of neglect is no culture at all!
Rather - Waterflow has developed a system that is very robust in terms of shock
loading and capacity, has the ability to deal to a garbage grinder, and will deliver
consistent results even under pressure
Nature does look after herself!
However…
Although Natural Flow is a natural living system,
as with all living organisms a little care will ensure
that it will run at peak performance for many years.
Virtually maintenance FREE
We do it simpler, Natures Way…
SYSTEM

Natural Flow System and greatly encouraged to maintain periodic checks of their
system.
This mainly involves simple visual checks;
▪ Worm numbers and tray loading
▪ Any pump alarms (if applicable) are working
▪ Dose siphon operation (if applicable)
▪ Condition of plants in Plant Filter (if applicable)
▪ Disposal field operation
We do it simpler, Natures Way…
