What does it take to understand the benefits of safe water and wastewater system? Droughts, floods and famines?
We were discussing the recent flooding tragedy in Pakistan and I was struck by the discussion, being not a quite a year from the floods that wreaked such havoc in Cobb, Douglas and Paulding Counties, I found the discussion illustrative of the differences in our countries. The floods here were devastating; I was one of the fortunate. My home was not affected, and I was not charged with the difficult task of speaking with our citizens who had seemingly lost everything. I was fortunate to watch the technical skills, dedication, and technological advances we have put into action to avert a far greater tragedy than the loss of homes. These professionals continued to provide safe drinking water and sanitation. Yes, there were tragic effects; there were lives lost, there was massive property loss, and there were a few public advisories to boil water because systems had been washed out and compromised. The longest lasted 6 days. We had wastewater treatment plants that went down or lost tertiary treatment, but plants were back on line in a week. The amazing and largely unknown part of the floods was what did not happen. As citizens fled the flood waters, water professionals remained at plants inundated with those same waters, were out running temporary services where lines had been washed out or making emergency repairs to ensure continued service. Lastly, they deployed all the technical knowledge at our disposal with a level of dedication every citizen should know about to ensure that the foundation of our way of life, our water treatment and distribution system and wastewater treatment and conveyance systems, remained viable.
It is often what we as American citizens do not know that would make the greatest impact. Look at the reality and aftermath of the Pakistan floods. We never had to call for 15 million water disinfection tablets and receive only 3 million. We did not have to set up special medical centers to stem the outbreak of Cholera, a water-born disease. Our citizens did not have to take to supply drop sites to find bottled water to slake their thirst.
As a water professional I am often challenged by how we make the average citizen understand not the cost of water down to the penny of their bill, but the value of water to their very way of life. Is the message in showing them what they don’t know? The privileges they take for granted. The talk we had yesterday went on for about a half an hour. That means in the developing world 83 children died of water born diseases while we discussed the luxuries afforded to us by the water and wastewater profession in the US. Do our citizens ever mark the time by thinking while I ate my lunch 166 children in the US grew, played, and went to school because of what water professionals do?

Why Water? - A reminder in the Face of Tragedy

Most of the citizens in the United States have been affected by the coverage of the devastation in Haiti resulting from the recent earthquake and aftershocks. The loss is raw and devastating. As a water provider I was struck by a recent article by the associated press on the relief recovery and staging at the Haiti Airport outside of Port Au Prince. The article covers much of what anyone would expect. The airport is not designed to accommodate the amount of air traffic arriving with medical aid and supplies, etc. Within all the expected facts and figures on landings per hour, is a striking sentence and an important reminder for those who have chosen this profession. The U.S. military coordinator, who has taken the role of relief air traffic controller, is discussing the priority landing schedule and simply says “planes carrying water and water purification land first.”
This sentence was probably missed by most readers. Those that noticed may even have thought, “well of course. You can’t live without water. We learned that in kindergarten.” As an individual who chooses everyday to work in this field because of a deep sense of purpose, I sadly wonder how many of us who learned this years ago, live it today. Haiti is an epic reminder of what the absence of water can mean (rioting in the street, desperation, violence, and even death) just some of what the Haitian people have suffered. In the U.S. we have had glimpses of the importance of clean available water: severe droughts, recent floods, and Hurricane Katrina are just a few. In the face of tragedy I believe people help and people learn what is really valuable. The people of Haiti need water before medical supplies, before shelter, and even before food. It is a good reminder for us to appreciate what we have as citizens of this country and it starts with and is built upon the water and wastewater treatment and conveyance infrastructure.
Next time I am asked why I choose this profession I think the answer is simple “water lands first.”

What's it worth to have that 'chemically treated' lawn?

Who doesn't like a beautiful weed-free lawn in their front yard? We believe an attractive lawn earns us the approval of our neighbors. Dave Barry, the syndicated columnist said, “The average American home owner would rather live next to a pervert, heroin addict or communist pornographer than someone with an un kempt lawn.”
But the question is what is it worth to have that ‘chemically treated’ lawn or how large a price will we continue to pay for our manicured green carpets?
As Americans, we spend $40 billion per year caring for our turf and lawns- that’s ten times more than is spent on school textbooks! But it smells so good when it’s cut, it’s so pleasant to look at, it’s fun to roll and run on, it’s alive, it’s green and natural. Botanically speaking, a lawn is far from natural. Turf grass is a monoculture, developed to suppress, and out-compete all other species that would normally germinate in its place. If you choose to plant and maintain turf grass, you are essentially eliminating diversity in your home garden.
Well, I will keep the biological diversity issue for some later discussion but let’s focus on the nutrients and fertilizers that we have been applying to our lawns.
Did you know that :
The hazardous lawn chemicals are drifting into our homes where they contaminate indoor air and surfaces, exposing children at levels ten times higher than pre-application levels.
Of 30 commonly used lawn pesticides, 19 are linked with cancer or carcinogencity, 13 are linked with birth defects, 21 with reproductive effects, 26 with liver or kidney damage, 15 with neurotoxicity, and 11 with disruption of the endocrine (hormonal) system.
Of those same 30 lawn pesticides, 17 are detected in groundwater, 23 have the ability to leach into drinking water sources, 24 are toxic to fish and other aquatic organisms vital to our ecosystem, 11 are toxic to bees, and 16 are toxic to birds. With numbers like this, the only logical question becomes: is this really necessary and what can we do to stop or prevent this kind of contamination?
Some 100 million pounds of pesticides are used by homeowners in homes and gardens each year, even more when commercial companies are added in. Suburban lawns and gardens are known to receive far heavier pesticide applications per acre than most other land areas in the
As far as I remember, storm water run-off from non-point sources (such as farms, residential lawns) contribute to anywhere from 60 to 80% of the nutrient loading in our streams. How? It is as simple as rain falling on the chemically treated and overly fertilized lawn and running down the roadside gutter to the nearest creek. Big rain events result in major nutrient and chemical ‘shock’ to the urban creeks and streams and result is really worrisome.
The world is rapidly changing and with it are perspectives on the use of toxic lawn chemicals and the hazards they pose to our children, families, neighbors, wildlife, and drinking water sources?
I am NOT advocating against having a lawn or a green yard. Rather, they are important from preventing soil erosion. What I am advocating is putting a simple thought behind the ‘routine’ practices. Educate our selves and be more responsible about our actions for preserving our environment and be responsible for sustainable future for us and coming generations.
Resources are out there to help you out.
Mulching, planting native plants and shrubs, customizing the fertilizers per your soil / garden’s needs rather than blindly applying fertilizers, going ‘organic’ route for weed control and fertilizing are just a few simple ways to have environmentally friendly lawns.
In most cases, doing ‘the right thing’ is economical is the long run and may be even short run. Just give it a careful thought!

Let's have a debate....who is using that water?
Somehow our discussion on 'consulting' turned to 'water issues' in general.
I was amazed how many very interesting topics we touched on....each one of them worthy of having a debate.
I am hoping to pose these questions and issues to the readers of this blog and I am inviting you to have a dialogue or at least express your opinion.
First on the list is - Who is using that water?
Jay mentioned to me that he recently moved to a community where he did not receive any water bill. Water and sewer charges were included as part of the HOA (Home Owners Association) fees.
At first, this sounds great.....no water bill! How wonderful...
Think about it for a moment and the picture becomes clear.
Although, there were no individual water meters on homes, the 75-home community had one common water meter and water bill was evenly distributed to all residents. Cost of the water and equivalent sewer bills were included as part of the HOA payment.
So, I asked him...
Does everyone in your community have a lush green yard?
The obvious answer was Yes. Beautiful lawns.
Second question, how many people do you have in your house and how about the next five houses on your street?
Jay said - we are two but our neighbors on both sides have three kids.
And sure enough....he got the gist of where I was going with these questions.
The point is....with such arrangements, people don't have any incentive to value water. Why would someone fix their leaky toilet at home? Fixing it might cost them close to $100 versus letting it run and the let everyone in the neighborhood pick up the tab for the water wastage.
What about an underground leak on the pipe within the neighborhood? No one would see if, no one would feel it (in form of water bill) - it will never get fixed.
Jay understood the issue very well and did make a note to bring this up in the next HOA meeting. Although, water is not a significant component of the HOA fees right now, it could and I would say....it would in a near future if the community continues to operate this way.
He has quiet a few uphill battles to fight still. Installing a water heater on every home is a significant upfront cost. In some cases, water utilities / providers will charge anywhere from $2,000 to $3,000 to tap the line and install a new water meter.
So, who would pay such upfront cost?
A lot of the water utilities (providers) have water conservation plans.
However, my hunch is the water utility may not want to play ball in this case.
Installing water meters on individual homes will eventually lead to lesser water consumption. Less water they sell, less money they make. Every utility is virtually hurting for revenues and unless they increase the water / sewer rates.....they can't make up for the deficit.
The other side of the question is - why would any utility (water provider) even allow such development?
Whose responsibility is it to promote 'water-wise' development? How do you think this issue can be resolved?
Back to the bigger issue here...
Atlanta has very limited resources and water being the number one in my list. We are paying far too less for water to be thinking about it and preserving it. Drought of last three years had brought much needed attention to the value of water but......we are back to the 'same - old - habits' after the good rain in the spring this year.

GAWP Scholarships and you!
With current state of economy and market conditions, a lot more people are going back to school to get further educations and students are taking longer to graduate. School enrollments are approaching new highs. However, with dwindling funds, the school endowments are also dropping fast. Research grants have been cut back and a very few students are getting assistantships or funding.
In such tough times, students' should seek various innovative ways to get the funding for their education.
One such way is to get a 'scholarship'. Some of the scholarships may not be significant in amount, but in a tough economic drought, every drop counts!
GAWP offers a variety of scholarships to full time students. A list of available scholarships is provided below:
• GAWP’s Undergraduate Scholarship
• GAWP’s Frontline Undergraduate Scholarship
• GAWP’s Graduate Scholarship
• GAWP’s H2Opportunity Undergraduate Scholarship
