Steel rainwater tanks

rainwater tank

As we head into the cooler months in the Southern states, we are getting more rainfall, so it is an ideal time to look at getting a rainwater tank. This will mean it has time to fill up for garden use in the drier months, or allow you to plumb the tank into the toilet or washing machine for year round use.

With a range of tank materials out there, we thought that it is worth considering why steel is one of the most common materials used in tanks.

Benefits of steel rainwater tanks:

  • Strong and durable, usually lasting for up to 25 years
  • 100% recyclable
  • A good looking and stylish garden feature
  • Modern steel tanks include a polymer protection to prevent corrosion
  • Consistent thickness preventing stretching or bulging

There are some limitations to consider:

  • The polymer coating on the inside of a steel tank is not resistant to prolonged exposure to sunlight so you will need to make sure you have a cover on your tank
  • Some chemicals used to prevent mosquito larvae can also affect the polymer so you may not be able to use these chemicals
  • A minimum of two metres of plastic pipe should be between the tank and any copper fittings as they cause corrosion.

Michael Smit recently caught up with Stuart Heldon from Tankworks to talk some more about the benefits of their rainwater tanks. Stuart talked about how their tanks are designed to order, so no matter how small the space someone has in their yard, they can build a tank to fit.
