Water & Waste

It's Blog Action Day again - and 2010 has a timely theme: water.

Change.org|Start Petition 


It's a theme that was prominent at the 2010 Climate Leadership Summit of the American College & University Presidents' Climate Commitment (ACUPCC), which took place this week in Denver.

Keynote speaker James Woolsey, former CIA director, focused his talk on the national security implications of our energy use (as well as the social and environmental implications).  Of course you can't have that conversation without talking about climate disruption and water.

During the business roundtable, moderated by ASU President Michael Crow, water was again a focal point.  Jonathan Lanciani, COO of Organica Water spoke about the need that companies like his have for sustainability-literate graduates.  He also spoke about the serious water challenges our world faces - 2.5 billion people live in "water stressed" areas, global demand continues to grow, and large parts of our energy system (including some clear renewables) are water-intensive.

Organica has an exciting approach - essentially taking the "living machine" concept and creating systems that are small, efficient, and suitable for urban and institutional use.  Waste water goes in the system, and comes out the other end clean, and ready for re-use as grey water (for toilets, irrigation, etc.)

Living organisms do the work - bacteria, microbes, plants, and animals eliminate the need for toxic chemicals and energy-instensive systems.   The systems are aesthetically pleasing, reminiscent of botanical gardens.  And they're odor-free, with upfront costs comparable to traditional systems, and lower operational costs for the life of the system.

Organica's system is just one example of how sustainability constraints can drive innovation - and how we can create economic opportunity and improve the quality of life for everyone by taking a proactive approach to moving towards sustainability.

Stay going.

The Birthday Barrel


So, it's my birthday, and I just had to brag on my present right away - a rain barrel! As you can see, it's pretty much just a big plastic barrel (of which the dog is very skeptical), but it's got a top that serves as a big filter so you can simply place it under the downspout of a gutter and fill 'er up. Looks like that filter-top comes off pretty easily too, which should be good for clearing it out, and cleaning the inside of the bucket now and then, if needed.

It'll stay in the basement for a couple more months, as we're still snowed in here, with more icy rain expected today, but come spring we'll be collecting our roof water for irrigating the back yard permaculture "farm".

Anyone guess which sustainability principle this helps out with? ...primarily SP3, as we use too much water we're essentially degrading the natural system of the water cycle by physical means. Also, as we put stuff (like our waste and chemicals to treat it) in the water and contaminate it we're getting into SP2 territory, and of course, in many areas and instances irresponsible water use can have serious SP4 consequences.

Anyway, anyone with a house or suitable apartment should get one of these and rig it up - helps cut down on run off saves water, pretty cheap and easy to set up. Happy birthday to me! Stay going...
