Garden Designers are always looking for ways to return water to the ground naturally through infiltration back into the ground, rather than sending it off into storm drains.
Many are taking up the challenge to 'disconnect the downpipes' to prevent water ending up in underground drains. By disconnecting your downpipes, you can store water in a rainwater butt for use in the garden, channel it off to top up a water feature, or use it to irrigate your garden planters directly.
One of my favourites tricks is to use a traditional Japanese-style rain chain, or kusari doi.
Rain Chains break the fall of the water from the roof, guiding it visibly downward to the ground, or into a rain barrel for storage.
There are an excellent selection of Rain Chain available at UK Garden accessories supplier Garden Boutique and at RainChains.com or Gutter Supply in the USA
Rain chains can be beautiful as well as useful in a garden scheme
