When you write about something like water, you run the risk of the material being biased with your point of view. I have realized my point of view is about water, just plain old water:  Conservation, reuse, cost of energy generating clean water, availability and contamination of water   I just read an article, which I found confirms what we all know about the US.  We consume more than any other country, and of course that means we probably waste more than any country. 

We Americans are a people that are the most giving and charitable on this planet, yet we waste more than some will ever have.  You cannot give water to other nations and people in need, but you can conserve for our future.  Please check out this link http://www.yesmagazine.org/issues/water-solutions/just-the-facts-water-footprints from YES magazine’s new issue to see how much we consume and think that we could save 30 to 40% of our personal residential use by recycling our greywater to flush our toilets. 

Hello to all those who read my blogs. 

We were written about and we did not even know it.  The best kind of publicity is truly word of mouth and unsolicited.  Thank you to Michele Melio for her kind words.  To view her article check out this site http://www.examiner.com/examiner/x-5397-Denver-Green-Initiative-Examiner~y2009m11d15-Colorado-Green-Tech-MeetUp-Green-Grey-water-recycling

The Denver Water Board is raising the rate you pay for water by 13%.  Additionally, water users should expect to see increases continually for next couple of years.  This information is noted in the Denver Post’s editorial page on November 15th , 2009.  www.denverpost.com/opinion/ci_13776994?source=pophome

Water Legacy asks:  Should we be concerned?

Our mission is conservation through reusing greywater to flush your toilets. Reusing greywater causes less water (up to 30%) therefore reducing your consumption of fresh residential water.  In Denver, the water rates have already gone up 81% since 2001.  The biggest challenge facing water conservation is that people expect the price of water to be cheap and the supply abundant.  As prices increase, one will look at reduction of cost and that is through conservation. 

We ask that Denverites and citizens of the west become more fully aware of methods of water consumption reduction and take time to evaluate the use of greywater to flush your toilets.

FORT COLLINS - Graywater - nonpotable water from showers, handwash sinks and laundry - is used for residential landscape irrigation in a number of states in the Southwest; however, little is known about long-term effects of this practice, according to Colorado State University civil engineers.

Sybil Sharvelle and Larry Roesner, professors with the Urban Water Center in Colorado State’s College of Engineering, are in the first year of a three-year $370,000 graywater study awarded by the Water Environment Research Foundation to investigate the effects of using household graywater for residential landscape irrigation. They are sampling soil, plants, and water at homes with graywater systems in California, Arizona, Texas and Colorado. Four of the homes have graywater systems that have been in place for more than five years, and four additional homes will have new systems installed before spring of 2009.

Three homes with systems in place for more than 5 years - in Colorado, California and Texas - have been tested to date.

The study is one of four projects that Roesner and Sharvelle are leading on campus. The team also is working with the CSU Department of Facilities Management on several projects involving campus facilities including:

-Construction and monitoring of a wetlands treatment system for graywater at the Atmospheric Chemistry building on the Foothills campus. Students planted bull rushes and cattails last summer that, so far, are removing nearly all of the pathogen indicator organisms in sink and shower water, Sharvelle said. Researchers are also hauling shower and laundry water from a university residence hall to the Foothills campus to increase the quantity of water treated.

-Installing an anaerobic digester at the Atmospheric Chemistry building to treat toilet water or “blackwater” and test it as a source of renewable energy. Anaerobic processes generate methane, which can generate electricity.

-Plumbing one wing of the new residence hall, under construction, for complete capture of graywater from sinks, showers and laundry water; in addition, water supply lines to toilets are being plumbed to use either domestic water, or non-potable water (irrigation water or conditioned graywater) for toilet flushing. Studies by Sharvelle and Roesner will determine what level of treatment of graywater is required to make it suitable for toilet flushing. They are working with Water Legacy, a Colorado manufacturer of graywater treatment systems.
