Most homes these days have gutters along the perimeter of the roof that collect rain water and send it through downspouts. In some communities this water runoff is sent directly into the local sewer system where the water is then sent elsewhere. In other communities the water just drains out onto the property, ideally away from the house so that it won't cause any damage to the foundation (I've seen some of the damage that poorly maintained downspouts can cause - it's not pretty).
Recently I've seen two alternative methods for handling rain water that are smart and Eco-friendly. The reason I say that they are smart is because these are very simple methods for using this free resource, rain water, instead of using up resources to send it somewhere else, or just letting it flow onto your property creating a puddle.
The Rain Chain
According to research I've done on the Internet, rain chains originated hundreds of years ago in Japan. They are considered a decorative alternative to regular downspouts. Here are some photos I found - as you can see they can be very decorative. Some of these decorative rain chains can produce pleasant sounds as the water flows down. The ones that I saw in person were very plain, just a chain hanging down from the gutters and connected to the ground where they "fed" a rain garden.
Rain chains can drain into a variety of receptacles like basins, bowls, saucers, barrels or pebbles. They cannot replace conventional downspouts in all situations - it is recommended that they hang away from the wall of your house by about three feet. Not all homes have eaves that are far enough away for rain chains, through some people figure out a way to improvise and make it work. You can find more information at these sites and others:

Rain Garden
A rain garden is an planted area filled with plants that prefer moist soil. The rain garden should be arranged so that the water from the rain chain or a cistern flow naturally (by gravity) into the garden and away from the house.
Cistern
When I heard that some homeowners in Highland Park were using a Cistern to capture rain water, I envisioned a big ugly tank on the property somewhere, or on the roof. I was pleasantly surprised when I had a tour of the home and found a cistern with a beautiful stone facade at the front of the home. This cistern collects rain water from the roof of the home - all of the gutters feed into the cistern, which can hold over 80 gallons of water. This home is situated on a bluff overlooking Lake Michigan. During heavy rains, this home is not contributing to flooding or erosion and there is no water going into the local storm sewers. Using a low-tech gravity system, the water from the cistern is drained into a rain garden on the property by the home owner (by opening a simple spigot), and then it goes into the underground natural aquifer, as nature intended. Since none of the other plants on the property need any watering, the cistern provides all of the water required for outside usage. No sprinkler system needed here! (I will be writing about other Eco-friendly aspects of this lovely lake-front home in Highland Park in future posts! The homeowners provided an inspirational tour of their home.)
If you are building a new home or remodeling you have a great opportunity to do something to help the environment - water management is just one area to consider in your plans.
I would love to hear about any other Eco-friendly ideas for utilizing rain water. Please post your comments!
