Submersible Tank

If you have a liquid storage problem in a remote area then Polyworld’s Submersible Underground Liquid Tanks are your solution. We have designed these tanks to conveniently fit a six or twelve-meter shipping container and are easily moved on-site. The Subby is modular and can be manufactured in any configuration of hemispheres and centre cylinders. Extra strong, ideal for water or sewerage treatment. We also do ultra-heavy duty underground storage, using a massive double wall HDPE pipe – 10,000L and bigger.
