Hi, I live in the lowerbluemountains SYD, (10 mins Penrith) and really
want to splurge on a large watertank 9000 - 20000litres. (snip)

The poly tank does seem reliable and robust and is easy to transport
and move if you decide it's original placement is not quite right. (snip)

It's instructive to examine brochures from a number of poly tank
manufacturers. If you are getting a tall tank, you'd want to make
sure that its wall thickness increases towards the base of the tank.

(snip) As for being thicker at the base, that's a load of bullshit, and
the guy that suggested that has no bloody idea.
How do I know all this. I've been on tank water for the last 25 years, and
all by tanks are now Poly.

What rot.

Tanks with thicker plastic at the bottom and lower part of the walls is
preferred by experienced rural dwellers as many farmers have found that poly
tanks that aren't thicker on the bottom and lower walls split.
