Rainwater Tanks:

Rainwater harvesting is very popular across Australia, and particularly in Brisbane – our government has been encouraging rainwater tanks for many years now. Most rainwater systems involve collecting rainwater runoff from the roof via rain gutters and storing it in large tanks. The water can be used to irrigate the garden, flush toilets, wash clothes, even fill the pool. Rainwater harvesting also reduces stormwater runoff, helping to reduce local flooding.

Rainwater tanks are a great investment to make. They are good for the environment, as well as your pocket! In areas with good rainfall, the savings on your water bill can be very significant.

There are a few different types of rainwater tank solutions, which suit different situations around Brisbane. At Salmon Plumbing, we install the Eco Sac and Select Water Tanks made of stainless steel and plastic.

Stainless Steel Water Tanks

In Brisbane, some of the advantages of stainless steel tanks are:

  • Durability – they are extremely durable and hardy.
  • Longevity – they do not corrode or crack, providing a quality product for decades.
  • Hygiene – the water stays cool even in hot weather which prevents potentially harmful bacteria and mould from growing in the tank.
  • Flexibility – stainless rainwater tanks can be installed in homes, businesses and rural communities.
  • Range – Custom sizes are available.
  • Environmental – it can be responsibly disposed at the end of its lifecycle.

While the steel water tanks do come at a higher cost, it’s a good idea to consider the long-term benefits  you’ll receive when installing.

Plastic Water Tanks:

Plastic water tanks have increased in popularity in recent years. The advantages of this type of tanks are:

  • Lower cost – they are relatively inexpensive compared to say, a stainless steel tank.
  • Simplicity – plastic tanks are easy to install.
  • Structure – while it does need a firm foundation due to the weight of the water in the tank, the material of the tank itself is light and so the ground does not need as much reinforcement as a steel tank.
  • Mobility – The light weight of the plastic tank also allows them to be moved around if needed.

There are drawbacks to consider of course:

  • In a hot, sunny climate, plastic tanks can warm up the water in the tank, allowing mould and bacteria to thrive and thereby impacting the quality of the water.
  • Responsible disposal at the end of the lifecycle may be a challenge.

The Eco Sac

The Eco Sac is a flexible rainwater storage system that is installed under the floor or deck and remains out of sight. It is called a ‘bladder tank’ because it swells as water enters the tank.  It comes in as many as 66 different sizes, has no moving parts and is relatively maintenance free.

Some advantages of the Eco Sac bladder tank are:

  • It is favoured by architects and designers as it is tucked away under the deck or floor and does not clutter the landscape.
  • The tank stores more water per square meter than any other bladder tank.
  • The tank is contained by a steel frame and harness for safety.
  • There is a wide choice of sizes (65) and can be customised at no premium.
  • A 10-year warranty on material and workmanship provides assurance of quality.
