Water Efficiency
At the annual Sourcing USA Summit (a biannual meeting, jointly hosted by Cotton Council International and Cotton Inc., that “gathers global leaders along the cotton supply chain for an open exchange of ideas”), Erik R. Peterson, Senior Vice President, Center for Strategic and International Studies gave a presentation entitled “Outlook for Global Water: Can We Stay Above the Surface?”
Why do cotton growers care about water supplies, and why are their concerns relevant to the rest of us? Considering that agriculture accounts for 70% of water use, it behooves us all to stop and listen to what our farmers and growers have to say. Especially when, as Peterson points out, “the food production target for 2025 will require the flow of more than 100 Colorado Rivers.” Considering the contention and acrimony already surrounding water rights along the mighty Colorado, the prospect of coming up with 100 times the amount it already supplies to the western US is daunting and – hopefully – mobilizing.
With demand increasing and supply decreasing, efficiency and conservation naturally come to the forefront – only those solutions that incorporate smart water use, treatment, and delivery will help us not only sustain our current needs, but adapt to future challenges and opportunities. As Peterson points out, “One flush of a US toilet equals one day’s water use in a developing country. The bottom line is that water policy goes beyond altruism. A far-sighted study will help define the impact of dislocation and will identify areas of competitive advantage.”
Although it may appear at first that municipal water providers and the agricultural industry operate in two separate universes, their mutual dependence on a safe, clean, and reliable water supply binds them together – one cannot operate without considering the actions of the other. It’s often said that water is a shared resource, which makes me wonder if the current balkanization of our water supply – that clear demarcation between ag interests and muni interests – makes sense. Isn’t about time we present a united front against the challenges of scarcity and demand?

Wondering After a Winter Break

Water Efficiency
I’ve just returned from a trip to Spain, a country that’s certainly seen its share of water woes. Spain has suffered a water shortage for almost two years, and by spring of 2008 it had only received a third of the average seasonal rainfall. With reservoirs less than half full, the country is gripped in its worst drought since the 1940s. And in Catalonia the situation is even worse: Reservoirs are less than a fifth full, and, in April, Barcelona – a city known for its efficient infrastructure – was forced to import water by ship and train to prevent a water crisis prompted by extreme drought. The water was brought in from Marseilles, France and from desalination plants in southern Spain. And Barcelona is not alone, for many years now the island of Mallorca has depended upon imported water to meet its needs – especially the spike in demand during tourist season.
I was lucky enough to spend some time in Barcelona and Mallorca, as well as a few other destinations in southern Spain. What struck me while I was visiting was the ubiquity of low-flow fixtures throughout the region. Every hotel – whether it was a small, family-owned pension or a large, commercial chain – had bathrooms outfitted with dual-flush toilets and low-flow showerheads. In larger cities, like Madrid, the hotel rooms were also adorned with the requests for conscientious water usage that we often see here in the US.
Unfortunately, many times that’s as far as it goes – just a postcard asking you to hang up your towel and maybe turn the faucet off while your brushing your teeth. And yet, the traveler is an important demographic when it comes to public outreach and water efficiency. Studies have shown that when people are on vacation they tend to throw caution to the wind and put aside daily habits – including their normal water conservation efforts. It’s certainly an unwanted twist on “what happens in Vegas stays in Vegas.”
Tourism is big business in the US. According to a report by the Department of Commerce’s International Trade Administration, in 2007 “56 million international visitors from 213 countries during 2007, up 10% from 2006.” And that’s just international travelers. When you add domestic tourism to the mix, you can begin to see how much impact water-wasting tourists can have on a local economy and water parched region – be it California, Nevada, Georgia, Florida, National Parks, and just about any city, town, or hamlet situated near an attraction or interstate.
If the people of Spain are willing to mitigate the impact of tourism on their water resources by investing in water-saving technologies and low-flow fixtures, shouldn’t we, in the US, be doing the same before it gets to the point where our most water-starved communities are actually forced to import water to meet their needs?

Virtual Water

Water Efficiency
Discussing imbedded water costs and the influence of free trade and a global economy -
Let’s talk about “virtual water.” Defined as “imbedded water costs,” the idea behind virtual water is that any product – be it food or commercial goods” – requires a certain amount of water to be produced. Once a water scarce region identifies goods that come with a high virtual water cost, they can develop regional partnerships with their neighbors, who can produce the same item without the same strain on their own water resources.
The concept of virtual water has found its niche in the area of global trade. According to recent studies, 800 billion gallons of virtual water are traded each year. Most of that trade revolves around food and other farm products. And the potential impacts are dramatic – it takes 1,000 liters of water to make 1 kilogram of wheat, and a country able to import, rather than grow this crop itself, frees up water for other, more pressing needs. For countries with scarce water resources, virtual water allows a switch from an ag-heavy water use system to water-based sanitation services and drinking water.
For countries who are not in dire straights yet – like the United States – virtual water provides data that can be used for future planning. For example, according to Maude Barlow – Canadian water activist and senior advisor to the UN on water issues – the US is currently exporting a third of its water through the export of goods. (By contrast, both England and Japan import most of their virtual water.)
Does a third seem too high? With devastating droughts on the rise and a continuing struggle between urban and agricultural demand, should the US move toward a more balanced virtual water portfolio?

Water and Compromise

Water Efficiency
“Whiskey is for drinking. Water is for fighting over.” – Mark Twain
As with any scarce resource, water is valued – and fought over – throughout the world. With exponential population growth, an ever-increasing consumerist class (and all their attendant demands and requirements), and longer, dryer droughts deviling every continent, those fights over water are only going to get more and more extreme.
This week, an editorial by Brahma Chellaney in The Times of India warned about the growing tension in Asia over China’s water resource management. As that editorial points out, with its control over the Tibet plateau, China can direct and impact the flow of several major river systems – rivers depended upon by many countries in Southern and Southeast Asia. Because the region is already facing severe water shortages, Chellaney predicts that Asia will morph into “most likely flash-point for water wars, a concern underscored by attempts by some states to exploit their riparian position or dominance.”
But not all disputes over water are preordained to become international incidents. Case in point, the Mississippi Basin. This week, Arkansas and Missouri announced that the two states have come to an agreement to jointly study ways to protect watersheds and aquifers that share their state boundaries, the status of which will be released in a biennial report by officials from each state. Under the agreement, both states have also pledged to develop quality programs for their shared watersheds.
According to Arkansas Governor Mike Beebe, this agreement is designed to avoid the more contentious relationship that currently exists between the state and Oklahoma (including lawsuits filed against Arkansas poultry industry over water use and water quality). By contrast, the Missouri/Arkansas agreement promotes interstate cooperation, by laying the foundation for a systematic approach to prioritizing projects and coordinating monitoring and modeling efforts.
“This is an historic agreement between Missouri and Arkansas,” said Missouri Governor Matt Blunt. “Water quality is critical to jobs, economic growth, our environment, and the quality of life for citizens of both states. Watersheds and aquifers know no state borders, and interstate collaboration is essential to protecting our streams, providing healthy drinking water, and planning for future water needs. Stronger communication today will help avoid conflicts tomorrow.”

The Nine Steps
(Originally posted on waterefficiency.net)

Water Efficiency
On October 22, 2008, Washington-based American Rivers released its report on the Southeast’s water crisis. Entitled “Hidden Reservoir: Why Water Efficiency Is the Best Solution for the Southeast.” The report essentially states that improvements in water efficiency—demand reduction, pipe and pump rehabilitation, low-flow fixtures, and smart irrigation—will result in a bigger return on investment than large-scale infrastructure projects.
Overall, there are nine essential water conservation tactics outlined in the report:
*Stop leaks from aging and broken water pipes.
*Raise the price of water.
*Meter all water users.
*Retrofit buildings with water-efficient toilets, faucets, and appliances.
*Install drought-resistant landscapes, require meters for sprinkler systems, and charge more for irrigation water.
*Educate the public about ways to save water.
*Design new buildings that can capture rainwater to water landscaping, and recycle shower and sink water in the toilet.
*Determine how much water can be safely withdrawn from rivers and lakes, and don’t take more.
*Involve water users in water-policy decisions.
(nine steps summary courtesy of ajc.com)
In fact, American Rivers’ report calls the plan to build dams throughout the southeast—like the controversial Flint River project south of Atlanta—expensive as well as destructive. Ultimately, it’s the hit to the region’s pocketbook that might be the most persuasive. According to statistics provided by Hordan, Jones & Goulding, water conservation efforts would cost no more than $250 for every 1,000 gallons of water saved. The dam? That price tag would be significantly higher: an eye-popping $4,000 for every 1,000 gallons of water saved.
Dams are a popular “go-to” solution when the going gets tough, and a community finds itself at the losing end of a dried-up water source. In Georgia, for example, the Metropolitan North Georgia Water Planning district has its heart set on four new dams in four different counties. Then again, with credit markets drying up as fast as a Georgia river bed (sorry – I couldn’t help myself!), the great “dam plan” might be stuck in a holding pattern, at least for the time being.
And that may provide a much needed cooling-off period. The “nine steps towards reducing water consumption and protecting water resources” delineated in the American Rivers’ report shouldn’t be taken as suggestions, but, instead, treated as mandates—not just for the Southeast, but for the entire country. Now is not the time for extravagance of thought or action. We’re going to have to tighten our belts and protect all of our dwindling resources because—as we are all now painfully learning—treating your assets (be they money, fuel, or water) with wild abandon does not build a foundation for a better future, but actually erodes any progress made and puts us all in jeopardy. So what do you say, are you ready to make the “nine steps” your mantra?

The Wall Street Ripple Effect

Water Efficiency
Scary story #1: Due to the collapse of the US housing market, mayors in many parts of Florida have been warned that their municipal tax base will likely shrink by $1.5 trillion this year.
Scary story #2: Last week, Buffalo, NY’s comptroller’s office confirmed that rising interest rates on the variable rate bonds used to finance improvements to the municipal water system have cost the city an additional $90,000 in borrowing costs.
We all know these examples are not isolated incidents.
It looks like the Wall Street meltdown is the gift that keeps on giving, including – it appears – the harsh reality that the cost of retrofitting, repairing, and rehabilitating our aging infrastructure just got a whole lot more expensive. If this isn’t a crisis, I don’t know what is. After all, in 2005 the American Society of Civil Engineers released a study indicating that over the next five years the US would need to spend over $1.5 trillion to whip US infrastructure into “reasonably decent shape.” And the EPA has said that it’s going to cost upwards of $440 billion over the next 20 years to repair our water and wastewater systems.
Shrinking tax bases, rising interest rates, and a tightened credit market – not the ideal environment for promoting infrastructure investment. There’s been lots of talk by pundits, news anchors, and candidates about Wall Street versus Main Street, but is it really an either/or situation? As the examples above prove, the financial and institutional health of our communities is directly dependent upon the wellbeing of our financial markets. Nobody got into this mess alone, and it’s doubtful that one-sided solutions will be strong enough to pull us out of this economic nosedive.
We need innovative thinking, multi-layered propositions, and a commitment to continue to invest in our country – its people, its structures, and its foundation – even in the face of frightening statistics and skittish investors. Now is not the time to freeze cityworks, shelve construction plans, or curtail in any way the repairs that must be made, the retrofits that must be installed, and the rehabilitation that our water and wastewater systems desperately need.

De-Centralizing
(Originally posted on waterefficiency.net)

Water Efficiency
Whether you like it or not, we are in the middle of a water crisis. You can blame it on climate change or aging infrastructure or green-lawn addicts, but whichever devil you choose the outcome is still the same: a diminishing supply struggling to meet an ever-growing demand.
Decentralized water systems (both treatment and delivery) can attack the problem of a shrinking water supply in two ways. First, advances in water reuse now allow for pristine, potable-quality water to be discharged back into the water supply, thereby curtailing the amount of water “lost” to pollution. Secondly, when onsite water treatment is combined with water reuse, we can insure that valuable drinking water is not squandered on green lawns in the desert or urban carwashes.
While municipal water treatment and delivery systems are most often associated with centralized systems (like city sewers or water utilities), the refinement of treatment technologies, ever-grander land development, and the push to “green” public and private industry is sure to change all that: one day onsite water treatment will go beyond the backyard septic system and bleed into the municipal market where it can reach its full potential and vastly improve the management and conservation of our water resources.
In Europe, that day has already come…
The public sewer systems in Germany are over 100 years old and rapidly deteriorating. Experts warn it could take years and several billion dollars to rehabilitate the centralized systems currently in place. The high cost associated with maintaining the existing centralized systems has prompted the exploration of alternative treatment systems. “As with an old car,” explains Dr. Harald Hiesll of the Fraunhofer Institute for Systems and Innovation Research ISI (Fraunhofer-ISI), “if the costs for repairs and renovations start to increase, you should think about whether to make further investments in the old system or whether a new system would be more sensible in the long term"
In April of 2003, the Fraunhofer-ISI initiated the AKWA 2100 project in order to “investigated alternative water infrastructure systems.” The study concluded that although rehabilitating the current centralized system was the least expensive option, abandoning a centralized system altogether in favor of a combination of decentralized water treatment and water reuse was the better option. According to Dr. Hiessl, the sustainable aspects of combining onsite water treatment with water recycling far outweighed the 5-15% increase in cost.
Although this study was conducted in Europe, it has international implications. The conclusion drawn by the study – that decentralized systems in an urban environment are “technologically and economically feasible”– should serve as a clarion call to municipalities around the world.
There are several reasons for a municipality to encourage onsite water treatment. A decentralized system allows for greater flexibility when it comes to growth and development. Onsite water treatment facilities also allow for the development of previously inaccessible areas, opening up development opportunities for communities bursting at the seams. Of course, as cities expand, the strain on water resources increases. What better way to mitigate increased water demand than to combine water treatment with water recycling?

Personal Responsibility Versus Government Action
(Originally posted on waterefficiency.net)
By Elizabeth Cutright

Water Efficiency
It’s an age-old argument: How much should we be held accountable for as individuals, and at what point should the government step in to help? When it comes to water conservation and efficiency, the question becomes even more complex: Can public outreach and a call to action be enough to inspire change, or will real results happen only after rules and regulations are enacted and enforced?
We’ve highlighted several successful public outreach programs in the magazine. Communities like Denver, Co and Seattle, Wa are just two examples—both cities have made great strides in encouraging involvement and stirring enthusiasm for water conservation and efficiency amongst its citizens. In Seattle, the Saving Water Partnership program—which is sponsored by a group of local utilities that fund water conservation programs in Seattle and King County, and includes workshops and a Web site—promotes the 1% Water Conservation Initiative, a plan to reduce personal and business water consumption 1% every year for 10 years. (For more information, go to www.savingwater.org) In the meantime, Denver’s citywide billboard program, with slogans like “Be Responsible” and “Use Only What You Need,” serve as a constant reminder to residents to stay aware and vigilant about their water usage. (For more information on Denver’s program, go to http://useonlywhatyouneed.org).
These programs work, but are they enough?
At one point, will we have to take a serious look at local, state, and federal conservation, and efficiency statutes and regulations? Some cities and states have already begun to make and enforce water conservation laws. In Georgia for example, the Georgia EPD regulates the withdrawal and use of Georgia’s ground and surface water resources and has the authority to prohibit residential outdoor water use. And in Texas, several water conservation house bills have been enacted, including rules imposing new conservation prerequisites and easing the way for greater use of “graywater” for landscape purposes. In fact, in most drought-stricken areas you can find some type of rule or law that dictates at least some facet of water usage and conservation.
Local control appears to be somewhat effective, but can we leave it up to the Cities and States, or is it time for the Federal Government to step in?

These programs work, but are they enough?
At one point, will we have to take a serious look at local, state, and federal conservation, and efficiency statutes and regulations? Some cities and states have already begun to make and enforce water conservation laws. In Georgia for example, the Georgia EPD regulates the withdrawal and use of Georgia’s ground and surface water resources and has the authority to prohibit residential outdoor water use. And in Texas, several water conservation house bills have been enacted, including rules imposing new conservation prerequisites and easing the way for greater use of “graywater” for landscape purposes. In fact, in most drought-stricken areas you can find some type of rule or law that dictates at least some facet of water usage and conservation.
Local control appears to be somewhat effective, but can we leave it up to the Cities and States, or is it time for the Federal Government to step in?

Water Efficiency
At the AWWA’s training seminar Water Demand and Conservation Management: Planning, Policy, and Rates in April of 2007, participants were encouraged to speak up about the issues and problems they faced. I will never forget the frustrations described by the water utility manager of an affluent New England community. He told us all about his utilities’ many failures: the pleas for conservation that fell on deaf ears, the tiered-rate schemes that did nothing to diminish demand. He blamed his lack of success – in part – on the wealth of his customers; a majority of which were ready, willing, and able to use as much water as they needed and pay whatever price charged just to keep their lawns green.
Recently, my local online newspaper reported on a similar issue. According to Rob Kuznia, Noozhawk Staff Writer, two of Santa Barbara County’s high-end communities – Hope Ranch and Montecito – hit record water usage amounts for 2007.(Click Here to read more.) County officials expect demand to continue to increase through 2008, just in time for reductions in water supplied to them by California’s State Water project.
Increasing demand and decreasing supply obviously puts both water districts in a tight spot, and it was their customers who put them there. In the 1990s, residents of neighbouring Santa Barbara, Goleta, and Carpinteria all voted to reject the State Water project in favour of living within their means from a water resources standpoint. Voters in the Hope Ranch (serviced by the La Cumbre water district) and Montecito took a different tack, choosing instead to join the State Water Project in the hopes of tapping an unlimited water supply. This decision may have eased worries in the short term, but undoubtedly it led to the situation both districts are now facing: the illusion of unlimited water goading demand and codifying usage that would be considered extraordinary in any other context.
In fact, while the city of Santa Barbara receives most of its water from the local reservoirs and aquifers, the Montecito district receives about 22% of its water from the state water project. La Cumbre is even worse off, with 60% of its water coming from the State.
What I find most shocking is that, so far, neither district is using a tiered-rate system. As a result, the big water users pay flat rates (some of the cheapest in the country) and waste with impunity – with a majority of their water going to landscaping. It’s also important to note that both districts use two to three times the amount of water consumed by the rest of Santa Barbara County’s residents, yet they pay bargain basement prices to keep their lawns green while yards across the country wither and die (many to be reborn through smart irrigation and xeriscaping…but that’s a story for another time).
Apparently, both districts are considering adopting a tiered-rate system similar to the one employed by the city of Santa Barbara – in which case customers will pay for their water use based on a scale that raises the price per unit once higher-usage threshold has been hit. It’s your basic, the more you use the more you pay, scheme, that will – hopefully – catch the attention of the folks writing the checks. In light of how much water is being used by these communities, there’s no doubt a tiered-rate scheme will help raise revenue for the La Cumbre and Montecito water districts. But one has to wonder; when money is no object will high rates do enough to encourage conservation?

Water Efficiency
For the last several years, the Southern Nevada Water Association (SNWA) has experienced great success with its turf replacement program. Under the program, SNWA pays property owners $1.50 per square foot for grass removed and replaced with a water-efficient landscape, including artificial turf. According to its Web site, SNWA estimates that by replacing thirsty lawns with “water-smart” alternatives, the average property owner can save thousands of gallons per year.
No doubt inspired by SNWA’s success, the Metropolitan Water District of Southern California recently began its own rebate program. As of July 1, 2008, both commercial and residential property owners are eligible to receive a 30-cent rebate for replacing grass with synthetic turf. The district anticipates similar water savings, about 33,000 gallons per year for a 750-square-foot parcel.
Similar turf replacement programs have sprouted up across the country as water scarcity and extreme drought conditions have pushed many communities to look for water-saving alternatives to traditional lawns and other water-intensive landscaping. The Synthetic Turf Council estimates that upwards of 3,500 synthetic playing fields exist throughout the nation, with another 800 installed annually at universities, parks, and stadiums.
As an artificial turf user myself – I’ve got about 20 square feet laid out on a rooftop patio at home – one of the most attractive features of artificial turf is that it stays green year-round with no irrigation needed. We’ve all felt that sense of satisfaction when a previously dry patch suddenly blooms with color, even if that color is fake. But now it appears the pigment used to keep this grass green contains lead chromate, which many of you might remember from the massive Chinese toy recall that happened earlier this year.
In fact, a Center for Environmental Health (CEH) study, released on June 23, 2008, included test results showing high levels of lead in all kinds of artificial turf – from the type used on big, stadium-like installations, all the way down to the stuff you can buy one yard at a time at your local home improvement center. Reaction to the test results was swift: On June 25, the CEH initiated legal action against the retailers and synthetic turf companies under California’s Proposition 65 law.
This is not good news for the MWD, but the storm’s been brewing for a while. In May of this year, the California Senate passed a bill sponsored by Senator Abel Maldonado (R-Santa Maria), calling for a state study investigating the health and environmental impacts of natural versus synthetic turf fields. And earlier this year, the Centers for Disease Control (CDC) released its own warning about potential lead exposures from turf, stating that “As the turf ages and weathers, lead is released in dust that could then be ingested or inhaled, and the risk for harmful exposure increases.”
Additionally, when the New Jersey Department of Health and Senior Services (NJDHSS) closed several artificial turf fields, one of the potential hazards cited was the possibility of ingesting the turf dust created from dissolved turf fibers. And although the artificial turf industry continues to assert that its products are safe, the US Consumer Product Safety Commission (CPSC) has launched its own investigation into the potential risks of lead poisoning from artificial turf.
So what is the solution? On the one hand, there is no denying that replacing real grass with artificial turf can save thousand of gallons of water … but at what price? Are our kids really at risk, or this just another “shark week” moment – just one more opportunity for the media to ramp up the hype and induce consumer hysteria?

Titans of Industry - Should Big Business Control The Tap?
(Originally posted on waterefficiency.net)

In many parts of the country, water utilities depend on tiered rate structures to promote water conservation: the idea being that as the gallons increase, the cost goes up and the water usage will decline. This works…sometimes. There will always be that one customer who cherishes his lawn and is willing to pay whatever it takes to keep his jewel green.
In the United States, 3/4ths of water systems are public, which affords us the luxury of using water rates to promote conservation. Other countries are not as lucky. In fact, many struggling nations with crumbling infrastructures have chosen to turn over their water utilities to private companies. Known as the “Water Barons” or “Big Water,” these companies build and/or manage municipal systems for profit.
Some of the more successful private water companies offer a virtual genie’s lamp of promises. Just turn your system over to us, they imply, and watch as new pipes are laid, old leaks are fixed and every man, woman and child gains access to pure, plentiful tap water. All this while instituting a rate system they argue will fund system improvements and promote water conservation
The reality is not so pretty. Although there have been some successes, privatization of water utilities has resulted in a long list of tragedies: in China citizens are sometimes forced to pay a quarter of their annual income for barely usable water; in South Africa those unable to pay turning to untreated lakes and streams (resulting in the worst Cholera outbreak in the nation’s history); and in South America, unfinished projects are often abandoned in the wake of civil unrest, leaving the task of reinstating the defunct and barely functional municipal systems in the hands of under-funded and fragile new governments.
Can increasing the cost of water decrease water waste? Of course, especially if the rate increases are combined with conservation education and government-sponsored tools (i.e. low-flow rebate programs and free water audits). But when you are dealing with a region experiencing extreme water shortages and substandard or nonexistent infrastructure, rate increases can be counterproductive and even cruel.
What is the answer? I think it depends on whether or not you are asking the right questions. Although water can be a commodity – something to be bought and sold based on the balance of supply and demand – that is not its only identity. End users in the third world struggle to meet the daily demands of survival. There is no expendable income to fund an ornamental rose garden or patch of vibrant green sod. They count themselves lucky if the well has yet to run dry. Ultimately no one can forgo water and survive: it’s not just a “want” it’s a basic need.
So the question is not “can water rates promote water conservation?” We first need to determine whether we are committed to fair, equitable, and cost-effective water distribution that rewards conservation where possible but does not deny access in the process. Within that context, I think it’s fair to then ask, “should water delivery be a for-profit undertaking?”
