Amhurst Tanks and Poly Products offer a wide range of Aqualine Steel Lined Tanks. The galvanised tanks have the strength of steel, the corrosion protection of a galvanised product and the real water holding capability of a sturdy polyethylene tank liner. The Aqualine range comes in sizes from 20,000L all the way up to 360,000L and everything in between – see below for a list of the whole range.

Aqualine only use the best raw materials in the manufacture of their tanks and their expert installers ensure that the completed tank is fully assembled and ready to go.

Approced to the AS/NZS4020 standard for potable water the liner and tank are suitable for storing drinking water.

The tanks come complete with a galvanised access ladder, Geotextile liner, lockable access manhole, inlet strainer, 100mm Gal overflow, 50mm outlet and ball valve.
