  "....the only bladder tank solution supplied in a steel frame with pipe work fixed via a steel mounting plate...."

The eco sac® water bladder tank (PDF) (1 Mb) is the preferred water bladder solution of architects, designers and hydraulic engineers - and it is the best under house and under deck water storage solution for you because: 

  • it stores more water per square metre than any other bladder tank so you can ensure you have the most amount of water storage
  • it has the largest range of standard sizes available in the market. And if a standard size won't fit in your home or premises we will make a custom size for you (we don't even charge a premium for custom made bladder tanks!)
  • it gives you "peace of mind" because you know your bladder tank water storage solution is contained within a steel frame and harness ensuring it will not move or touch any part of your home
  • the eco sac® material is independently tested and accredited to the Australian drinking water standard (AS/NZS 4020)
  • all pipe work into and from your bladder tank is fixed and secured in place by a unique steel mounting plate attached to the frame so there is no risk of the weight of the water cracking your pipes
  • eco sac® bladder tanks are Australian owned and made. They come with a 10 year prorata warranty on material and workmanship


Why is eco sac® better than other water bladder tanks?

The market leading eco sac® bladder tank is the only framed bladder tank available in Australia. The design of the eco sac® bladder tank (patent pending) is widely recognised as the best bladder tank solution because:

  • the steel frame ensures that it will not move. It is really important that a bladder tank does not touch any part of your home or building structure as 1000 litres of water weighs 1 tonne!
  • the steel mounting plate (patent pending) fixes the pipe location and removes any stress from the pipes. It is critical that rigid pipes connected to bladder tanks are not put under any stress
  • the one piece geo textile harness protects and holds the bladder tank within the steel frame and helpsnto maximise capacity as the bladder fills into the shape of the harness
  • the side entry fittings (inlet and outlets) are standard plumbing fittings that plumbers "connect to" every day & that comply with the plumbing standard (AS3500).
  • the connections are all permanently accessible for on-going maintenance
  • the eco sac® inlet is a market leading 100mm standard overpipe fitting ensuring the maximum amount of rainwater is delivered to your bladder tank without the risk of water backing up your downpipes (whih happens if you have a tank with a 50mm inlet)
  • the eco sac® air vent is the largest standard air vent in the market to allow air to escape when water flowing through downpipes pushes air into the bladder. Large air vents are critical to ensure that bladder tanks are not put under pressure.
  • All welds are overlapped and corners folded for maximum strength
  • No issue of sediment being regurgitated through the tank as happens in bladder tanks where the inlet is underneath the bladder
  • each and every eco sac® bladder tank is tested before it leaves the factory and is assigned a unique serial number for warranty tracking

All eco sac® rainwater bladder tanks are available via the Waterplex national network of resellers in Sydney NSW, Melbourne VIC, Brisbane QLD, Adelaide SA, Perth WA and Canberra ACT.
