Andrew and my dad have installed 3 new tanks in our front yard, so we can water our new edible front garden and driveway. The tank in the second photo has an identical one behind it, and they are connected, so they will have equal amounts of water in them. We've gone from one big tank with 4,500L capacity, to 4 tanks with a total of 11,700L capacity. After all the rain we had over the last 2 weeks, including nearly one month's worth on Friday, the tank on it's own is full, and the other 2 are well on the way to being full. Water security...check.
