    Delivery Requirements:

    Nylex delivery vehicles can exceed 19 metres in length – check to make sure there is sufficient room for the truck to manoeuvre. Nylex drivers will make every effort to unload your tank as near as possible to the tank’s final location. If you need to lift the tank over obstructions, you will need to organise a crane and have it on site during delivery. Nylex provide a driver only so you will need 1 additional person for tanks up to 13,500 litres, 2 people for tanks from 13,500 – 22,700 litres and 3 people for tanks greater than 22,700 litres.

    Given the size of rainwater tanks and the length of our delivery truck and trailer combinations, Nylex is governed by strict Over Dimensional Load regulations. Therefore delivery restrictions and additional charges may apply depending on the size of the tank and your location. Customers in remote locations should confirm the availability and cost of deliveries when placing a tank order.

    • Yes, they can be completely recycled.

      Polyethylene is already regularly recycled and used again in different products. The poly tank industry has shown a real concern for our environmental future by working with Auckland University on finding new ways to make it easy for tank owners to recycle their own tanks at the end of their product life.

    • Rainwater is harvested from roofs, channelled down gutters and through downpipes. These surfaces can also catch dirt, dust and insects that can be captured in your water tank through the water collection process.  Leaf strainers, gutter guards and water diverters all provide protection against dirt and dust entering your tank.

      Over a period of time, your water tank will build up sludge and muck that sits on the bottom and the walls of your water tank (especially if it has corrugated walls). There are many things which contribute to this such as:

      • wood fires (smoke can settle on your roof)
      • high tree areas (sticks and leaves can fall on your roof)
      • high traffic areas (polution from traffic can settle on your roof)
      • some new roofs (they have a clear film which eventually wears off)
      • Animals (dead possums, birds, mice etc)
      • Mosquitos (which can lay eggs and breed)
      • Eucalyptus (from over hanging trees) etc

      It is recommended that you clean out your tank regularly every 2-3 years to avoid such issues occuring.  

      Straight (smooth sided) water tanks are the easiest to clean.  How do you clean your tank?

      1. Once the tank is empty, spray down the inside of your water tank with a hose.
      2. Use a medium bristled broom to scrub down the walls. (do not use chemicals)
      3. Give the wall a final rinse and wash any muck out through the outlet.
      4. Your tank is now right to fill again.

    • Concrete Slab

      The no-compromise solution to base construction is a reinforced 100mm concrete slab.  A slab can be square or round.  The base should always be 100mm larger than the diameter of the tank. Prior to pouring the slab, ensure the ground has been 100% compacted. Your base will be compromised if soil has not been compacted and will affect your tank guarantee.

      Crusher Dust/Sand

      A crusher dust/sand base is considerably cheaper than a concrete slab, but may need to be augmented over time.  Heavy rain falls can erode a crusher dust base and may cost you extra if it needs to be repaired. It’s best to use treated pine sleepers, screwed together at the ends to create a retainer for the crusher dust/sand but many other materials are appropriate.  Ensure base is compact and sturdy prior to laying down the crusher dust/sand. Base should be anywhere from 25mm to 50mm high when compacted.  Crusher dust or sand is available from any landscape material suppliers.

      Pre-Cast Concrete Slabs

      1. A series of pre-cast concrete slabs or pavers on a sealed bed of sand makes an appropriate base for a slim cylinder tank or a tank stand.***Please note that all Wall tanks must be on a concrete base for safety.
      2. Prepare a flat area for your tank. Clear an area that is 300mm wider than the diameter of your tank.
      3. Make sure the ground is 100% compacted and that there are no rocks, stumps, tree roots or anything else that could affect/damage the base of your tank and void your guarantee.
      4. Place sand on base. Put in a bed of sand (packing or river sand) about 25mm to 50mm thick. Bluestone dust is also acceptable, just ensure it is well packed down.
      5. Flat & Level. Make sure your base is flat and level so that the base of the tank is fully supported.
      6. Tank delivery. Once the tank is delivered and fitted, put either sleepers, pavers or bricks around your site and box the sand in. This is important, as it keeps your base stable and prevents the sand from washing away.

    • There are poly tanks that have been giving loyal service storing liquids for over 30 years, however there is no definite "life" period for a poly tank.

      As with any other product you buy, its "life" will depend on how you install and maintain it, after it leaves the factory and what the service environment is like.

      Most tanks will far outlive their warranty period, however the Australian & New Zealand Standard requires a design life of 10 years.

    • There are a few factors to consider when buying your first tank. You many want to consider the following:

      1. What is the tank being used for?
      2. Where will I put the tank and how much room do I have?
      3. How will I put the tank into position? (consider fences and driveway access)
      4. How much water can I catch off my roof?
      5. What is my budget?

    • The size of your tank shouldn’t be determined by either of those things as we’ll never know how long it could be between rain events. So we always recommend looking for the biggest tank you can reasonably fit into your yard & one you can reasonably afford.

    • Plastic, or polyethylene (poly), water tanks are now the biggest selling sector of the booming water tank market.

      Polyethyelene has been developed and tested in the market place over many years for the manufacture of upright water storage containers.

      Polyethylene cannot rot or corrode, and is UV stabilised for Australian & New Zealand conditions. It is also resistant to algae growth as a result of its formulation.

      Water tanks made from polyethylene are available in a range of sizes and designs to suit your needs and to make an attractive addition to your home.
