3. Why should I consider a rainwater tank?
Australia is one of the driest continents on earth. As rural
and urban population growth expands, our demand on
existing water resources will increase. It is everyone’s
responsibility to reduce our footprint on earth and reduce,
reuse and recycle. This includes harvesting water for
personal and industrial use.

4. Why should I purchase a Team Poly tank?

5. What do I need to consider before I buy a rainwater
tank?
Try to select the largest possible tank capacity for the area
you have available. In rural locations, space is not always a
problem and so a traditional round tank is the best solution.
However, in residential areas space can be a real problem,
particularly if you are limited to locating the tank down the
side of a house or in a small back yard and so a Slimline tank
may be more practical.

6. How do I calculate my rain harvesting capacity?
10mm of rain on an area 100 sq. metres (10m x 10m) of your
roof area will provide 1,000 litres of rainwater in your tank.
Log on to www.teampoly.com.au to use the ‘Rain Harvesting
Calculator’ for your specifications or refer to page 4 of this
catalogue for further information.

7. What are Team Poly tanks made from?
Team Poly rainwater tanks are made using high quality UVstabilised
food-grade polyethylene.

8. Is my roof surface suitable for collecting rainwater?
The most suitable roofing materials for collecting potable
water* are:
• Colorbond® steel sheets or tiles
• Zincalume® steel sheets or tiles
• Glazed tiles well fired
• Concrete/cement tiles
• Clay tiles
• Composite tiles - bitumen based
[* Potable water is water fit for human consumption - safe
drinking water.]

9. Do poly tanks split at the seams?
There are no seams in poly tanks. Lines may be visible on the
outside of the tank that look like joins. This is where the two
parts of a mould join together. Team Poly tanks are not made
from two sides joined together, they are formed as one solid
piece during the polyethylene manufacturing process.

10. Are mosquitoes a problem with Rainwater Tanks?
To prevent mosquito breeding and contamination, it’s vital
guttering and pipe work should be self-draining and fitted
with drainage points and screens.

Site Preparation

There are many factors that will determine the most appropriate location of your rainwater tank. First walk around your house and note the locations of your downpipes. The closer the tank is to a downpipe, the simpler and cheaper the installation will be. Once you have selected an appropriate site, you can begin to prepare this site for the tank.

1.
Check the relevant regulations relating to rainwater tank installation with your local council.

2.
Your Team Poly rainwater tank should be handled with care. When moving into position, avoid rough and sharp surfaces.

3.
The site must be a solid, level, compacted base, that extends beyond the diameter of the tank that will not be eroded by wind or rain. Suitable bases include brick, concrete, gravel or solid dolomite surface between 300mm and 400mm in depth.

4.
Water tank stands can be used but must be designed by a qualified consulting engineer.
Plumbing Please ensure your tank is installed by a qualified plumber in accordance with you local council regulations.

Insert a length of flexible pipe to absorb shocks and movements of pipe fittings from tank. Position pipe directly into ground to avoid running over pipe and damaging fitting and/or tank.

Unsupported pipe work puts excessive strain on fittings and tank wall.
Note: Team Poly warranty may be voided if tank placement or plumbing is not installed as specified.

Gutters & Roofing
The guttering on your roof is a key component in your rainharvesting system and will need to be regularly cleared of any leaves or debris. Damaged guttering should be repaired. On some existing houses, the guttering may need to be adjusted to direct the water to the corner of your house where the tank will be installed.

Tank overflow must be piped away from tank to avoid undermining tank base.

1. SELECTING A TANK
Our quoted lengths and widths are the dimensions when the tanks are empty. The tanks will get
narrower and shorter as they fill. The quoted height is what the tanks will reach under gravity fed
stormwater. The height of the tanks can also be limited – see below. The required clearance above
the tank is 30mm (3cm). The quoted volume is the volume when the tank reaches its quoted height.

2. PLACEMENT AND GROUND PREPARATION
Wet Earth Bladder Tanks are specifically designed for placement under houses or verandas, but can
be used in other locations as long as the following conditions are satisfied.
For under house use the most important aim is to prevent any water from getting under the house.
These guidelines are designed to prevent or minimise the chances of water loss under the house.

2.1. Level Ground
The aim is to position the bladder tank so that it will not roll or slip. We do not recommend locating
a bladder on a surface with an angle greater than 5 degrees (12:1).
Where the bladder tank is to be placed on a surface with a slope, digging a 20cm deep channel
about half the width of the bladder tank along its length will provide additional stability. Care must
be taken when digging near walls and supports so that these are not destabilised.

2.2. Ground Type
The ground surface should not have sharp edges, or be of a material that causes slipping or
scratching.
Sand is an ideal surface, and in many cases soil is also good. Concrete is generally ok, but some
concrete surfaces might scratch the surface of the tank over a number of years.
Tanks are supplied with a Geotextile Tank Protector which provides additional protection from
puncture, slipping and scratching.

2.3. Don't Lean
We do not recommend that bladder tanks lean against walls or structural supports as they can weigh
a significant amount when full and could contribute to movement over time.

2.4. Minimise Sunlight
To maximise the lifespan of your tank we encourage you to minimise direct sunlight exposure to
your tank. While the tanks are UV stabilised, the heat and drying effect of direct sunlight can
impact the material over time.
In most cases tanks are located under a house or veranda/deck which reduces exposure so sunlight
protection is not necessary. If a part of your tank is exposed to direct sunlight we recommend
covering it eg with shade cloth.

3. CONNECTING YOUR TANK
The aim of connecting your tank is to maximise water collection, while allowing water to overflow
into your stormwater when your tank is full. It is also important to take into account that bladder
tanks change shape as they fill and hence the fitting locations on the tank can move. All our tank
inlet and outlet fittings are located on the tank ends which minimises this movement.
The following diagrams show possible ways of connecting your bladder tank. These diagrams use
our Bladder Tank Pipe, which has some flexibility while being almost impossible to collapse.

Overflow Height

3.1. Inlet and Outlet Fittings
Our tanks have three (3) 50mm male threaded connections. The tanks have two (2) 50mm male
threaded connections on one end and a single 50mm male threaded connections on the other end.
This allows for the inlet and outlet to be at the same or different ends. Tanks can also be supplied
with female connections on request.
When putting thread tape on fittings you should put enough on the fitting so that it makes it hard to
manually turn. In some cases this may require up to 20 turns - clockwise when thread is facing you.

3.2. Air Release
Our tanks come with a 15mm barbed fitting in the middle at the top. This fitting allows air to escape
as the tank is filling. This improves the rate at which the tank can fill. To prevent any water coming
out of this when your tank is full we recommend connecting some 15mm clear pipe, 12mm garden
hose or 13mm poly pipe to it and making sure the top of this pipe is above your overflow level. This
is shown in Diagram 1 on page 2.

3.3. Bladder Tank Pipe
Our Bladder tank pipe is unique in that it is flexible and can be shaped, yet it will not collapse. A
1m length of pipe can be bent into a circle without collapsing.
We recommend using a 1-2m length of pipe with a 90-degree bend as shown in the images above.
To change the shape or straighten the pipe it is necessary to warm up the pipe. Once warmed up and
reshaped the pipe will retain its new shape and will provide flexibility around that new shape. The
easiest way to reshape the pipe is to leave it outside on concrete/paving in the sun for about an hour
before attempting to reshape. Poring boiling water over it can also help.
To connect Bladder Tank Pipe to fittings we recommend putting some water-based lubricant (ie KY
Jelly) or dish-washing detergent (less preferable) on the fitting to make it easier to slide into the
pipe. You will need to dip the end of the pipe in fresh boiling water for 60 seconds. Make sure that
the boiling water covers at least as much of the pipe as the fitting needs to slip into. The pipe will
become soft and stay soft for about 10 seconds and should slip over the fitting.
It is important to ensure that you bladder tank pipe has a bend in it as shown in the diagrams above.
This allows three-dimensional movement of the tank fitting which ensures stable connections.

3.4. Tank Height
The heights we list for the tanks are the heights at which they will achieve their quoted volume. The
tanks will actually fill higher than this level. You can limit your tank to this height or lower if you
do not have the height space. You do this by the height you position the overflow system
(illustrated in the diagrams) so that the tank will overflow when it reaches the required height. Your
overflow should be no more than 200mm above the quoted height of the tank.
Tanks should never be filled above their quoted height using a pump. Doing this will void the
bladder tank warranty. Bladder tanks are designed to support gravity filling pressures and will not
support pump filling pressures.

3.5. Leaf Filter and First Flush Devices
We strongly encourage the use a Leaf filters to keep leaves and other debris out of your bladder
tank. Wet Earth suggests the use of the Frogmouth Filter or Leaf Eater/Leaf Beater to keep leaves
out of your system. These items can be found on our website in the water tank section.
We suggest that you consider installing a first flush diverter system. Whether this is required will
depending on local regulations, your location and what you plan to use your water for. Wet Earth
has the Rain Harvesting First Flush Diverter on our website. Note that in many cases it is easier to
use a Leaf Eater or Leaf Beater with your First Flush device than a Frogmouth Filter.

3.6. Cascading Tanks
Wet Earth Bladder tanks can easily be joined together. The tanks have a 50mm female threaded
outlet fitting on each end, which allows the outlet connection to be at either end of the tank.
To connect your tanks together we recommend using our Bladder Tank Pipe. Depending on your
situation you may need to use some of the following fittings. These fittings are all on our website
under: Water Tanks > Flexi Bladder and Pillow Tanks - Domestic Fittings.
· NyGlass Threaded Elbow MF (male/female) 50mm (used to keep the bladder tank pipe bent)
· NyGlass Hose Tail 50mm
· 50mm Bladder Tank Pipe (per m)
· 50mm Bladder Tank Pipe Clamp

4. LEGAL
Most areas in Australia require work on stormwater systems to be undertaken by a licensed
Plumber. As a result Wet Earth strongly encourages you to get a Plumber to do the actual
connection to your downpipe / stormwater system.
