Hi Kim,
Dont use a shipping container for water,do you know
what was been in to over the last 3 years,?? no I didnot
think so,
If you have a high water table like you said then why dont
you use a pump,?build a small tank from brick, render the inside
it will save a lot of problems in the future.
I’m thinking of the long term aspect of a container in the ground
and any toxic material that was in the container could contamanate
your water supply over the years.”Please don’t use a container”
use somthing else.
Have a look around there could be a water system for sale,
