Polyethylene or plastic water tanks vs steel tanks

advantages of poly water tanks
There are advantages and disadvantages of both plastic or polyethylene water tanks and steel water tanks. Here are some points to consider before buying:

Advantages of plastic water tanks

  • Generally, poly tanks are less expensive than steel tanks; even the highest quality polyethylene tanks (such as those made by JoJo Tanks in South Africa) are still comparatively cheaper than similar sized galvanised steel tanks and much cheaper than stainless steel tanks.
  • Plastic tanks are lighter than steel tanks and are therefore easier and less expensive to transport.
  • When it comes to installation, plastic water tanks are generally easier to manoeuvre and require less labour to install when compared with steel water tanks. This makes installation less costly.
  • High quality, rotational-moulded poly tanks like JoJo water tanks have a similar service life expectancy when compared to galvanised steel tanks.
  • Plastic water tanks are available in a wider range of shapes, types and sizes.
  • Aesthetically, plastic water tanks can be better than steel water tanks as a wide range of different coloured plastic tanks are available. This makes plastic tanks easier to blend with the surrounding environment and comply with building codes where certain colours are specified or prohibited.
  • Polyethylene tanks are basically inert and do not react with most chemicals or salts that may be found in the water (even so-called ‘stainless’ steel tanks can react with certain salts and chemicals).
  • Rotational-moulded or ‘roto-moulded’ poly tanks, such as JoJo tanks, are made from one piece and therefore there or no seams to crack or split. Steel tanks are usually made with panels – the joins are inevitably weak areas and the first to corrode.

Advantages of steel water tanks

  • Stainless steel water tanks will probably have a longer service life (although at a much increased initial cost when compared to a good quality poly water tank).
  • Steel water tanks are fire-resistant – perhaps an important advantage where bush fires are common.
  • Being far heavier than poly water tanks, steel water tanks are a more difficult target for thieves.
  • Steel tanks are more difficult to vandalise or damage compared to plastic tanks

As can be seen from the above points, a good quality polyethylene water tank has many more advantages than a steel water tank (even when compared to expensive stainless steel water tanks).
