Swimming pools demand bigger water tanks, especially in our long dry springs. Unless of course you want to be single-handedly responsible for the emptying of Lake Wivenhoe. Fortunately squandering Brisbane's safe drinking water didn't make it to my parent's bucket list so they installed three large water tanks to top up their pool over the dry spell each year. This more or less made their little tanks superfluous so when they had their outside paving done they were set aside for someone else's rainy day.
The garage at our new place stands alone from the rest of the house meaning no water or power nearby so I've been making the trek from the house to the shed with buckets of tap water to keep the seedlings from turning into crispy flakes. Thankfully I won't have to do this much longer - those spare tanks from mum and dad's wound their way here soon after we moved and have been sitting patiently next to the shed waiting for the plumber to install them and for some of that wet stuff to fall from the sky (and no I don't mean lorikeet poo, although it is in greater abundance than raindrops at the moment).
