Dad has a water-barrel system setup. The other night, it chucked it down with rain and as luck would have it, both I and my brother were at dad’s flat. Enough water came down that the overflow on the second barrel couldn’t cope, so dumped water out the side.
The perspex panes in the top are to let light through – there is two fish, a couple of mussels, and a few water snails in the green barrel. The fish like eating the mosquitoes who think that the barrel is a brilliant place to keep their larvae ;). Click on the image for the full-size version 🙂
