Round or Slimline Tanks?
These days many states require you to have rainwater storage , unless you have access to recyled water.
But which type of tank will be best
In addition to the standard round tanks there are a whole range of alternative rainwater storage tanks available.
One popular shape is the slimline tank which will fit in a narrow space. I have even seen a row of them used as a boundary fence.
Before you make a choice it could be worth thinking about finding out if you can find room for a round tank.
Round tanks cost less because they are easier to make and use less material.
Typically the cost increase for a slimline tank over a round tank of the same volume is at least 50%.
A comparison from my local builders merchants:
- $1,200 for a Slimline 3,000 Litre tank
- $800 for a Round 3,000 Litre tank
If you haven’t the width to fit a 3000L tank you could perhaps look at getting two round 2,000Litre tanks for a similar price as the 3,000Litre Slimline tank.
Other advantages of the round tanks are they are a lot stronger, and easier to clean out.
