Rain Water Collection Update

I've ordered the diverter mechanism that channels rain water from the roof downspout into the tank. It's amazing how much cheaper it was to buy online. The base and the tank are ready, and put together, stand about seven feet tall. I thought I was painting the tank grey, but it turns out that the paint was Sun Microsystems purple. It looks nice, though. The concrete slab is slowly curing. I've also decided to lay bricks in the small space between the house and the slab, so I don't have weeds cropping up later, in hard to reach places.
