Poly Tanks - Daintree Range

As of 1 January 2004, the State Government made it compulsory to install a rainwater tank with all new dwellings.

Scroll down for sizes and dimensions ...

Our Upright, Slimline, Squat and Inground poly tanks are strong, light and maintenance-free. 

The tanks are made from food grade, UV stabilised polyethylene, using only premium quality Australian materials for Australian conditions. All materials conform to AS 2070 and Water Standards AS 4020. And we believe that the quality of our poly tanks is second to none.

The tanks are manufactured using an environmentally friendly process and can be recycled. Brass fittings are used and are installed in the factory under controlled conditions . . . no leaks!

Benefits include

• New generation Polytank Technology includes computer-aided, correctly designed rib design.
• No vertical join lines, offering extra strength and virtually eliminating the thin spots that can occur in some other designs.
• The strong dome design top is self-supporting and completely does away with the difficult-to-fit internal supports of other makes.

Delivery

Delivery is free to most areas and an additional 1/2 hour onsite is allowed to unload the tank.

Sufficient manpower must be onsite to help the driver unload. If your package includes the wastewater treatment system and poly tank/s, we will also be present at the time of delivery of the poly tank and will assist with unloading, but you may still be required to provide additional manpower:

Slimline Tanks
100-360 gallons  -  1 person required onsite
440-660 gallons  -  2 persons required onsite
880-1100 gallons  -  3 persons required onsite

Upright & Upright Squat Tanks
75-3000 gallons  -  1 person required onsite
4000-5000 gallons  -  2 persons required onsite
7500 gallons  -  3 persons required onsite

Placement of Upright & Slimline Poly Tanks

Do not use corrugated iron or wooden sleepers for the tank base.
Ensure the base is larger than the base of the tank.

1.  Position tank on a suitable base.

2.  If using a concrete slab, ensure it is even and level. Concrete must be 25MPa and 
     100mm thick with F72 mesh, sand or crusher dust and suitably retained to a depth of
     3-4" (75-100mm) using for instance cement strips, rocks, sleepers.

3.  Alternatively, mount tank on a sturdy hardwood or steel stand with gaps no greater
     than 2".

4.  The base must be larger than the base of the poly tank.

5.  A suitable flexible hose 12" in length must be placed between the gate valve and any
     other plumbing work.

6.  The tank overflow volume must be at least equal to the tank inlet volume, ie 2 x 90mm
     inlet pipes must have 2 x 90mm overflow pipes.

7.  The tank overflow must be piped away from the tank.

8.  It is recommended that you put at least 4" (100mm) of water into the tank or otherwise
     secure your tank from being blown away.

Colour Swatch



Every attempt has been made to faithfully reproduce the colours of the tanks. Bear in mind however that colours vary from computer to computer. If in any doubt, call us.

Inground Poly Tanks 

Our range of Inground poly tanks can be buried in the ground up to three-quarters of the height of the tank ... just ask us for details

Notes for the Inground Poly Tanks

1.   Prepare the hole. Ensure that the surrounding soil left in the walls of the hole is solid, leaving a 6-8" (15-20cm) gap to allow positioning the tank.

2.  If there is major seepage into the hole from the surrounding soil, the site will not be suitable. Make sure the tank site is well drained. Consult an engineer if necessary.

3.  A base of 2-3" (5-7cm) of sand or crusher dust must be placed in the hole and compacted.

4.  The tank must be lowered ino the hole squarely by crane.

5.  Tank must then be filled with water to above ground height, then backfilled with bedding sand or metal dust. Use cement stabiliser in the backfill medium.

6.  It is important that the tank be buried into the ground to ONLY three quarters of its wall height.

7.  It is recommended that your outlet pick up from the tank comes through the tank roof, or alternatively plumbing from the base outlet is needed.

8.  If there are 2 x 90mm inlets coming into the tank, you will need at least the same capacity in overflows.

9.  Overflow/s must be piped away from the tank to avoid undermining the tank base.
