Our Vortex Bladders™ make removing solids easy

We are the  only bladder/flexible tank supplier currently to offer an effective solution to removing solids from the water bladder. We have developed the Vortex Bladder™ with help from RCY in France, and worked on the installation and base requirements to address what is already an issue with other bladders here in NZ that draw the liquid from outlets around the sides of the bladder. Heres what we offer.
  • A central drain hole in the bottom of the bladder makes it easy to drain the bladder out completely.
  • Installing the bladder onto a concaved rather than a flat sand base which helps to gravitate solids and liquid to the central drain hole.
  • Then by creating a vortexing motion of the liquid and solids within the Vortex Bladder the solids are driven to the centre of the bladder where the drain hole is. This only needs to be done periodically and not every time you pump from the bladder

This combination is a very effective way of addressing the build-up of solids that will occur without an effective method of removal.

  • They are quick and easy to install, and don’t require major civil engineering work
  • Cost competitive to pond construction on difficult soils such as peat
  • You can install them on peat, with very little earth and preparation work
  • They are easy to shift to another location if required
  • They are safe, there's no risk of anyone falling in
  • Eliminates unwanted odours
  • Retains all of the valuable nitrogen, rather than losing it into the atmosphere
