Can you install my water tank?
We only manufacture and deliver Aqua Tanks® however we do provide an in-depth installation guide for anybody that would like to install the tank by themselves. A registered plumber or drainlayer can also install your water tank.
Where can I install my water tank?
Depending on what your tank will be used for you can install your tank at the most convenient location for its use.  The base the tank sits on is more important and must be flat with a bed of compacted Gap 7 or sand.

If you are laying a concrete base for your tank to sit on, the minimum depth should be 100mm, ensuring the sub-base is compacted prior to pouring the concrete.

Our larger tanks (16,000L and above) can be buried 700mm deep.

How do I keep my water clean?
The best ways to keep your water clean are:

  • Using a pre-tank filter to prevent debris from getting into your water tank.
  • Cleaning your water tank yearly.
  • Using a UV filter after your tank allows you to have clean water in your house.
