Green Options

LEED, for Leadership in Energy and Environmental Design, has become the alpha acronym when referring to green, or eco-friendly, buildings. The standard, from the U.S. Green Building Council, recently went 3.0.

Washington University in St. Louis, Missouri, is taking the green diploma to an even higher degree. University officials are betting a new Living Learning Center will meet the Living Building Challenge, the world’s most stringent green building rating system from the Cascadia Region Green Building Council, a chapter of the USGBC and its Canadian counterpart.

Do you have a rain barrel for your home?

More and more homeowners are using rain barrels to conserve water while collecting soft, non-chlorinated rainwater to nourish grass and plants.

This weekend, in Calgary, Canada, Clean Calgary Association, in partnership with the City of Calgary, will hold its 8th Annual Rain Barrel Sale.

With spring coming, local residents there are thinking about their lawns and gardens. Water usage in Calgary doubles in the spring and summer due largely to lawn irrigation.

Looking outside my window, the sky is cloudless, bright, a slight breeze. And it’s December, normally a time of frequent rain. While we here in the Sierra Foothills are not yet facing a water shortage, many people in the world are. And in places that do get sufficient rain, they may be lacking in opportunities to be physically active during the rainy season.

The Watree addresses both of these issues, in a device that some would say looks like an upside down umbrella. While mechanically complex, the idea is simple - Able to be stored in a retracted form, the Watree unfurls to become a large bowl to capture rain, which is then directed to a series of storage tanks underground, ready to be processed as drinking water, or later used to irrigate land.

A woman who set-up a simple system to catch and purify rainwater from her rooftop says that she gathers nearly enough water to avoid using the tap in her Austin, Texas home.

Just as technology continues to infiltrate the masses, becoming less and less a geeks toy, so environmental consciousness and awareness continue to spread. For some, it might be as simple as bringing calico bags to the supermarket. For others, it is taking your house off the grid and growing your own veggies.

But one area that a lot of families and households are stepping up in is the collection of rainwater.

It isn’t like this is a new activity either. Our ancestors would have spent a lot of effort to collect rainwater, to save themselves the need to trek down to the river or well. But now, it’s happening because across the planet, drought conditions are making life more and more difficult.

Editor’s note: Just like our friends at Low Impact Living, we’ve got passion for saving water… so we were very happy to see this post about a new technology for homeowners interested in doing just that! LIL writer Jason Pelletier originally published this post on Wednesday, May 28, 2008.

I’m often pleasantly surprised at how much interest and passion you (our visitors) display for water-saving technologies. Renewable energy is sexy, and eco-friendly cars are top-of-mind for most people these days, but graywater systems? Rain barrels? Rain gardens? Even water-conserving toilets and showerheads? They’re pretty hot too … I for one am thrilled, for not only have I spent a good part of my career designing stormwater treatment systems but I believe that water shortages are a pretty pressing and difficult environmental challenge that doesn’t get enough attention in these days of $4 gasoline and global warming.

The beauty of any of these water-saving technologies is that a) they achieve multiple benefits, saving water while reducing wastewater or stormwater runoff and b) you can see the results right at home. It’s pretty satisfying to open the valve on a rain barrel, see the water flow out and know that you reduced pollution downstream and also prevented water from being siphoned from lakes or rivers tens or hundreds of miles away.

There are some challenges, though. In order to really make a dent in your runoff, you might have to use ten or more rain barrels - not so great if you don’t have space or your downspouts are on the visible side of your house (or if you’re not Ed Begley Jr and just don’t care!). Cisterns give you more capacity, but you’re talking about a real construction project with some possible permitting hurdles.

Rainwater catchment is an ancient practice used widely around the globe to harvest and store rainwater for human consumption and irrigation. Dating as far back as 4,000 B.C., it is now commonly used in Australia, New Zealand, parts of Europe, Japan, India, Sri Lanka and Thailand as well as the Caribbean, Central and South America.

With more than 250,000 practitioners in the U.S. alone, rainwater catchment is experiencing a revival in parts of North America including Alaska, Washington, Oregon, and Canada. Hawaii, North Carolina and the more dry regions of New Mexico, Arizona and Texas already boast government incentive programs. Although maintaining water supplies for increasing population demands is one of the California’s biggest challenges, the Golden state does not have government-backed, financial incentives for rainwater catchment.
