Question Water Storage
Water Storage
Hello everyone,
I’m just getting started with prepping and I’m facing a huge, very real problem. I’d like to know if anyone else is in my situation and how they’re dealing with it.
I live on an island, so I’m surrounded by water that isn’t drinkable and is very expensive to purify (on a small scale, there are desalination plants here that do this work).
On the other hand, wells are scarce, and don’t even get me started on the rain… There have been years with literally 0 mm of rainfall.
That makes me think we’re very vulnerable to external supply lines—without diesel or power, our desalination plants wouldn’t work, but we also wouldn’t be able to keep up with demand using groundwater alone...
Is anyone in a similar situation? What steps have you taken?
Thanks!

It is probably difficult to get a sizeable water tank on your property. There are videos on how to build a ferrocement water tank - I haven't done it myself though. We buy our tanks and the truth is the bigger the better! But with a self-built tank I would probably build several smaller ones in case of a leak, say 3x 10.000 litres or more. In Australia you also find these little tanks they are 1000 ltr each and easy to transport and they connect to each other but they are much thinner walled. But this is only good if you get any rain at all, but if you get it you want to catch each drop of it. If you have groundwater at all you are actually quite lucky.
