Finally - water in sight

After much searching we finally located somebody who sells second hand IBC's locally. We picked one up and now have to decide where to put it and how to connect it. It holds 1000L and as soon as it's placed we can start filling it with tap water from the house until it's connected to the rainwater system.

Not sure if I want to put it underground or else how to hide it, as I really don't like the sight of it. Also the water will turn green if it stays out in the sun. Decisions...decisions....
