I have been testing this DIY rainwater collector and it seems to be working quite good:
The 200 litre water container is of course situated downhill and after a good rain, the container was overflowing with water. The container also have a water tap and a overflowing valve to add a series of containers in a row, when i really need a lot of water in the summer:
