You are gonna need them. One to transport water and the other to store. Need pump.
Yeah have not decided how I want to setup water yet and still have a lot of research to do on how to treat it etc, but I know I'll need them either way. These ones had diesel exhaust fluid in them so probably not suitable for potable water but it's non toxic so probably find as general use water after I clean them out.
At the very least I'll want to setup some water for general use like washing hands after going to the bathroom, mixing cement, etc.
And yeah need to look into pumps. 12v ones will be handy for filling tanks from a lake and then filling the tank at the camp.
This property is probably going to end up costing me a lot at the beginning.

But I technically have the money to pay it off cash, I just don't know the best way to transfer it yet so I don't get killed with taxes. First world problem...
