Another reason Quay says the department will continue its education program, is because of the challenge “to be sustainable through drought,” which he acknowledges how research tells them that the drought may last 20–30 years. “Phoenix is in an unusual position, in that, because we’ve done a very good job of planning our water resources, under normal conditions we have adequate supplies to meet existing and future demand,” he says. “If we can’t deliver water to meet the needs of a growing economy during times of long-term drought, then we will have failed to maintain a sustainable community. Attitude is the number one factor in drought response, and, maintaining attitude during normal times is very important when you have to start doing a drought response. Number two is planning. We tell people [that] drought is going to happen. If we’re not in a 20–30 years cycle right now, 10 years from now we may be. Eventually, it’s going to happen and we need to be prepared.

“We tell them there are things they can do today within their homes and businesses to help minimize the impact that will occur when we tell them they have to go into a drought response,” he says. “We tell them to design their irrigation system with the needs of individual plant types in mind. We’re not going to ask them to let their trees die, and they won’t if you have a separate way of watering them from turf—and, by the way, a tree that took 20 years to grow has a lot more value than turf you can easily replace if it goes brown. If you don’t have some type of cushion within your community, you’re in real trouble when drought hits.”

Seattle’s Program Success
Of Seattle's program, Dietemann remarks that, although the population has grown, the city still supplies the same amount of water that they have been for the past 10 years. “Our managers and elected officials look at our efficiency program as a good deal for our customers,” he says. “The average bill is not increasing significantly, and, although our rates do increase, this is balanced out by the fact our customers are using a little bit less water. It’s a zero-footprint philosophy in that adding one-and-a-half percent more people does not translate to greater water demands from our sources of supply. And, this is not only for people, but, also because we have a large responsibility for in-stream flow below our reservoirs for fish and aquatic life.”

The city of Seattle is committed to review their systems, and stay updated on the best methods. “Previously, water managers overbuilt and then sat back and didn’t worry,” Dietemann says. “Today, when our modelers tell us there’s a small chance we might have a problem in six months, we step up our regular efficiency programs, which means, not only customer demand efficiency measures—such as rebates and incentives and educational efforts—but also leak detection and repair work within the utility and how we use water to maintain our system—such as hydric flushing and reservoir overflows for water quality purposes.”

He goes on to discuss their water conservation plan. “As the modelers take a look at rainfall patterns, future snow pack, future rainfall conditions, and likely demands, we continue to make adjustments. If the situation improves, we back off. If the situation intensifies, we intensify our efforts.” By saving water when there is plenty, the city is able to “stock up,” for in the case of drought or dry months, he adds. “We get a lot a rain in the winter and chances are we’ll never get a shortage in winter, but we need to store that water to meet our demands in the late summer and fall.”

Dietemann comments on how the city must prioritize their plan. “If we feel that we need to move into our drought curtailment plan,” he says, “we start with voluntary suggestions and water efficiency tips, and then move into mild mandatory requests. If the situation then gets bad enough, we impose mandatory curtailments, most of which revolve around outdoor water use. For any of this to be successful, your populace has to believe the water system is being managed responsibly, and they’re not being picked upon or asked to make sacrifices because decision-makers haven’t done their job,” he remarks. “This kind of relationship is not something you can just turn off-and-on instantaneously; you build it over the years.”

Dietemann also responds once again to extra pricing. “We find people are fairly responsive to price, and, if you send them the proper price signal, they’ll make a responsible decision without somebody telling them what day of the week they can water,” he says. “We have tiered rates, but I’m talking about here about surcharges. It’s important that people understand the dynamics of the system. Usually a price surcharge will get a significant amount of water demand reduction right away, and this often forestalls the need to go into the more drastic mandatory measures. But, it needs to be significant enough to get people’s attention. It isn’t necessarily the dollar amount, but the concept that they’re going to have to pay 20 percent more. If folks are frugal, they won’t really see much of a change in their bill, but the people who use lots of water will. We try to be fair and equitable, and, after the event has passed, we settle up with people who have special circumstances.

Dietemann acknowledges that the key to the public's respect is to treat them fairly and being honest with them. “Rather than an army of policemen running around writing citations for people who are watering incorrectly, you invest the surcharge money into efficiency measures, such as for people to change out their toilet or change their business process. The beauty of raising the rates before you start building a big tab up doing all this other stuff, is that you are collecting some resources to enable you to get to that next step, which is media.”

Seattle also has developed a large financial incentive program with its commercial and industrial customers, where the utility actually cost shares up to 50% of the total installed expense for a business to change out to a more efficient technology. To facilitate this required convincing state legislature to remove the constitutional restriction that, as a public agency, a utility can’t loan credit or provide financial incentives to private businesses.

“It took educating our elected representatives to understand the philosophy of demand management and efficiency, to the point that it makes sense, to avoid the really significant environmental and dollar costs of new sources of supply, by investing that money to free up water and make it available for future customers—and, so it remains in the rivers for our environmental needs,” Dietemann says.

Cary’s Tier-rate System
How much of the western experience has been transported east? Cary, NC also has established a tier-rate system, so the customers who use the most water pay the most. Customers who want to install irrigation systems (a troublesome, new challenge now that in-ground systems, which used to be a luxury, are being included in new home development) must have their design approved by the city inspection and permit department. In addition to tier pricing, Cary has also imposed water budgets on their commercial accountants and large residential properties. Regulations also require that customers with in-ground irrigation systems must also have separate meters, so the city can track irrigation use. The town hosts waterwise gardening workshops, that emphasize the use of warm season turf for people who value lawns.

“The reason for our success,” says Cefalo, echoing remarks from her western counterparts, “is that we’ve established a steady base. No mater where you turn, you see something about water conservation. We have a well-established program that has created a water efficiency culture in our community."

There should be no difference between drought and conservation - they are the same thing.

In fact, Americans need to be made of aware of just how much water goes into all of their daily lives - both in their activities (ie showers, toilets) but in their products as well.

Hopefully the latest rains and snow won't lull us into thinking we've somehow dodge a bullet. We can still be in a drought situation when the storm drains are over flowing.

Interesting article...we hear all the time the word drought, but come the time water resources are run dry, where will we be then?

I would like to see more articles like this one - drought and resource management obviously go hand in hand.

I just read the article on leaks and when they have to replace all the infastructure that was put in eons ago water rates will skyrocket so get prepared and take matters and your safety into your own hands. Install a cistern from raindrops cisterns as soon as possible. Systems are available and can be installed by the handy home owner. Raindropscisterns.com

Maybe I missed it but I never saw where Rainwater harvesting was mentioned. Raindrops Cisterns has proven that one of the best ways to conserve water is collect rain water which reduces storm water. It dosen't get any easier.

All the way down to 270 gallons per capita? You've got a long way to go before you can begin to discuss conservation.

The float bulb on the flush valve that holds the valve open on most toilets is in need of discussion. If that float bulb is removed, the flushing only occurs while that handle is depressed. In our home this takes less than a second---about a quart, to clear urine. Thus homes that, in these hard economic times, need not go to the expense of a change out of toilets for the newer low flush units, merely a sharp knife and a steady hand to emasculate the toilets bulb is sufficient.

I spent several years as the USAID regional environmental officer in Africa where droughts are common and devastating. Usually land is given up because either water is no longer available or just too expensive. This may accrue to the increasing cost of pulling water from deeper and deeper groundwater resources or just mining out these resources. The end result sees vast areas laid to waste and exposed to the elements. This sees regional dust storms moving tons of soil into the air and thus across vast areas. This tendency toward dust storms is projected to happen more frequently here in the South West and Sun Belt areas. A return to Dust Bowl days. What is not being discussed here is the longer-term impacts of water scarcity on public health. When we start to look at this area we do, in fact, run into the purchased science and dogma of those who would rather not get into these public health discussions for fear of impacts on profits. Admittedly, this is a complex problem and can be viewed from several perspectives. In discussing water availability one needs to look at wastewater, its processing reuse, byproducts and their ultimate disposal. I will discuss two aspects of wastewater. The first is the need to make better use of reclaimed water (recycled water). But to do so, as a society, we need to carefully understand the costs and those costs include external impacts on public health. One aspect of the public health problem is the current inability of many reclaimed systems to exclude pathogens, their genetic fragments, pharmaceuticals, and emerging contaminants from the final product. There are ample peer reviewed papers in the scientific and medical literature that discuss these negative impacts but that body of literature seems to be lost on those controlling the resource---both industry and the regulatory sectors. The second issue lies with the disposal of solids from wastewater treatment. Again, there are ample data within the peer reviewed literature to alert the responsible parties to public health impacts, but this literature for purposes of politics and profit is mostly ignored. But then we have droughts and the thousands of tons of biosolids applied to thousands of acres for decades leaves pathogens, their genetic information, emerging contaminants in that soil. When this soil lifts in regional dust storms, the results from impacted lungs will likely overwhelm the health care system. The impact on infected lungs through multi-antibiotic resistant pathogens will likely see large portions of the population permanently disabled. In closing, the discussions of water and its availability or lack of availability need to be expanded beyond the classic issues of mere potable supply. Dr Edo McGowan

People are not afraid to face - DROUGHT - but to face it unafraid they need full open disclosure of all the issues associated with climate change or global warming, not the selected politically correct mantras of the day. For the past 40 years, we have educated Americans only to accept what is essentially purcha$ed $cience ... where the conclusion are reached first, then every attempt is made to secure facts to support our preconceived conclusions. Just give US the truth, the whole truth and nothing but the truth. Yes, there will be some trying time in the moment, but the future will be a bright and creative one
