After a long drought the two water butts filled in a couple of rainy days with some storms. The system uses standard components available from DiY stores. Diverter on the rainwater pipe down from the gutters of half the house, a 2cm diameter flexible plastic tube from the diverter down through the lid of the first 300 litre water butt, a flexible concertina pipe (which comes with water butt systems) from near the top of the first water butt and through the lid of the second which is 200 litres. A tap about 15 cm from the top of the second butt with a garden hose which takes overflow if the second butt fills. The water butts come with taps at the bottom, these are used for filling buckets or watering cans - or a garden hose can be attached.
This way most overflow goes down the garden to water plants, though if there has been a lot of rain the plastic tube from the diverter can be moved to go into a drain.
