sustainability


ASCE came out with more bad news about infrastructure.  60 Minutes did a piece about deterioration of bridges. The magazine American City and County has published a couple articles about the risks of aging infrastructure.  Asset management is practiced by few governments, and even fewer small ones.  The public doesn’t want to foot the bill and lobbyists want taxes cut further.  Where does it end?

The infrastructure crisis is a political and business leadership crisis.  Or vacuum.  The economy of America and much of the developed world was built on advanced (for their time) infrastructure systems constructed by governments with a vision to the future.  Some of this infrastructure was repurposed (federal interstate system for example), but much of it has addressed critical issues that hampered our development.  For example, the lack of water severely inhibits many third world nations.  Even when they have water, it is unsafe to drink or use.  In America, at the turn of the 20th century 1:100,000 people DIED each summer from typhoid.  Just typhoid, not all the other waterborne disease options.  Many more were sick.  And the population was much smaller.  Talk about reduced productivity.  Now we have advanced water systems, disinfection practices that protect people and pipes, and few event get sick from contaminated water.  Those that do, become headlines.  You don’t want to be a headline.  Productivity is up.  But we expect good water and can’t see the pipes.

Sewer is an even better example.  People just don’t want to know.  Flush and it’s gone.  But the equipment, treatment and materials may be even more complex than the water system.  But few people get sick from sewage because of the systems we have built.  Now think about third world examples.  Or conditions you have seen in documentaries, the news or movies.  Being in sewage is not a great place to be.  Even the manhole thriving cockroaches agree..

Stormwater is probably the laggard here, in part because changes in development patterns have overwhelmed the old systems.  Miami Beach experienced this when redevelopment replaced small houses on permeable lots with large housed with mostly impermeable property.  Oops.  Meanwhile road and bridges have received a lot of funding – with much to do (see bridge that collapsed on I-75 in Cincinnati a few weeks back).  Most states fund transportation at a magnitude more than water and sewer.

What is the problem?  Local officials do not convey an understanding of these complex system to the public very well.  In part this may be because understanding the maintenance needs is difficult and highly variable.  And many do not fully comprehend the assets they have, their condition, life expectancy or technological needs.  No one knows when things will fails, so maintenance or replacement of some equipment or pipeline is always the thing cut in the budget, with no real understanding of the consequences.

The public does not see the asset, assumes it will have a long life, so is unconcerned until they are affected.  Then it is personal.  The public does not understood the impact or value that these assets have to society – they tend to be personal focused, not societal.  That is a leadership issue.  That leadership starts with vision and communication from those that understand the issue to the elected officials that need to advocate for their infrastructure.  Elected officials need to take ownership of infrastructure.  It is like your house – you need to upgrade and protect it constantly.  You do not let that roof leak keep leaking!  Elected officials that do not invest in infrastructure, are letting the roof leak.  Making is someone else’s problem for political expediency is not leadership.

Despite the infrastructure crisis, the good news is that construction of piping is increasing – both new and replacement.  Every so many months, the magazine Utility Contractor will note current trends and pipe seems to be going up.  That’s good but there is a long way to go.  Better news – the construction of buildings is increasing.  That could lead to more revenues.  In Florida, all of a sudden finding experienced construction workers is a problem.  Things are definitely better economically, but are we taking advantage to improve the local infrastructure, or is you economy simply an infrastructure disruption away from another fault?


Orange County, FL has become the second school district I know of that has decide that giving students a zero on a assignment causes the kids to lose hope of passing so they just quit.  To address this problem, the worst grade you can give them is a 50 instead of a zero.  That way they can recover from one missed assignment.  Huh?!?!  No, you read this right.  The school superintendent was quoted in the SunSentinel as saying that only 43 percent of the students who received a 50 actually recovered to pass the class with a D.  I have several questions.  First, how does this policy teach these kids any responsibility?  For the kids that do their work, how is that fair?  What message does this policy send to the kids?  Be a lazy dumbass and do nothing and you can still pass?  That reinforces the concept of entitlement which we all agree is a problem in society that we need to overcome.  Finally, if one missed assignment causes the kids to fail, why are there not more assignments so missing one is not fatal?  That is what happens with my students (who still get a zero for not doing an assignment).

It would seem that such a policy is not based on an educational goal but more like a political one to improve school perception.  That is as bad an idea as having kids beg for money for uniforms and class trips etc.  Kids do not sell anything they just beg for money.  So are we teaching them that begging and panhandling is an acceptable career?  Seriously what impression does that provide to these young minds?  How does either experience prepare kids for the real world where doing nothing gets you fired, not rewarded, and begging for money vs actually work is also not rewarded.

Once upon a time, education was the purview of the wealthy.  American businesses argued that a basic education was needed to train a workforce for industrial jobs.    The American public education system was created with this in mind- to train the next generation of workers.  With education came great social and economic advancement.  We clearly are deviating from that goal.  Students need a good foundation in math, writing and reading (in English!), civics and science so they understand social responsibility, can communicate, understand how things work the world and can solve complex problems.  They do not need pseudo-science or politicized science, but real science.  Business understands this.  But where is the business community on job training in schools?  It would seem the business community has abdicated their responsibility to local districts who are trying to meet political goals, not economic goals.  Why are we not using all the extensive testing to figure out the strengths of students and encourage them to play to those strengths? Not every kid can go to college, or should, but that does not mean they cannot achieve or be successful.  They may need different training to hone their strengths.

Back in the day my Dad told me that as the education system was developed in his hometown of Detroit, students were given aptitude tests.  I was also.  The kids were divided up based on skills and aptitude.  Students were even sent to different schools as they got older that tailored programs to their interests and skills set.  Kids that the schools system felt had the aptitude to succeed in college had different courses than students that were less academically included but perhaps more mechanical, more artisan, more labor, clerical, etc.  Different kids go training to help them succeed with their skills.  Less academic did not mean less inclined to succeed or be successful. just differently.  And they had a better chance to be successful.  We seem to miss that today.

Today we have parents insisting that everyone be treated the same, and that no kid gets left behind.  But putting kids with different aptitudes, maturity, and academic inclinations in one class is destined to either fail for all, or fail for everyone but the average.  Such a protocol begets policies like Orange (and Broward) County that direct teachers to adjust grades so “Little Johnny” doesn’t feel bad.  Extensive college prep testing and disconnected learning discourage the less academic kids, leading to dropping out, or other behaviors.  Such policies and expectations by parent and political leaders are not helpful for building an educated society.  Instead we need to search further into the root causes.  Are there too few assignments?  Are they too disconnected for students to appreciate?  Should we sort out strengths and treat different students differently to discourage disinterest?  How do we assess their strengths and design programs to help students succeed.   And who takes responsibility for these kids?  And perhaps we should revisit some of the lessons learned from the early years of the industrial development (1930s) to figure out what they did well, and see how policies today frustrate those goals.  Maybe the way forward is rooted in the past.

How did southeast Florida not end up on the list of US cities with the worst drivers?  This seems like an annual rite for us and if you have lived down here you know why.  Things have not improved, so what does that say for Worcester, MA, Boston, Washington DC and Springfield MA that they took the top 4 spots?  Sometimes it is good not to be number 1!  LOL

A group called Idaho for Wildlife requested and got approval for a hunting contest open to children on public lands whereby they will attempt to be the child who kills the most wolves.  What could possibly go wrong here?  First the only ones with guns are children.  Those children are running around public lands trying to shoot the most wolves.  We assume there are people with them, but since they are trying to kill the most wolves, I would expect more shooting than normal.  So what if the critter is a coyote or fox or missing German shepard or guy working on a water system?  And aren’t we trying to bring wolves back because we have figured out that eliminating them vastly impacts the ecosystem negatively.  Maybe if Idaho for Wildlife (interesting misconcepted title) thinks there are too many wolves, wouldn’t trapping a few and releasing them in a place that maybe needs some would be a better idea?


Have we passed peak diamonds? Just as a prior blog outlined the concept of peak oil, gas, metals etc, the recent news not suggests that diamond miners are decreasing their exploration investments because the number of new finds is decreasing each year, and those found are far more expensive to extract than the current values.  Sounds like oil?  We find less each year, it is more expensive and current oilfield yields are on the decrease.  Phosphorous is similarly situated which is why there is much research taking place to find means to recover phosphorous from ag lands and wastewater effluent – recover phosphorous meant to be resold to ag interests as fertilizer as the price of phosphorous continues to increase as a result so increasing demand and decreasing supplies.

We are also being told that while peak diamonds have passed perhaps chocolate will become scarcer and the demand for chocolate is outstripping the supply, and the available land for cropping is being out competed by more lucrative crops in South America.  At some point the available land for many crops will be exhausted.  It is then that we reach peak agriculture?


2014 is almost over.  Hard to believe.  I have been attending or annual Florida Section AWWA conference, meeting up with old friends, making new ones and learning new things.  Conferences and connections allow us to do our jobs more efficiently because as we learn how to solve problems or where we can find a means to solve whatever problem we encounter.  It is a valuable experience that I encourage everyone to get involved with, especially young people who need to make connections to improve their careers.  The technical sessions seemed to be well received and popular.  That means that there are issues that people want to hear about.  Things we focused on were alternative water supplies, water distribution piping issues, disinfection byproducts, ASR and reuse projects.

The reuse projects focused on Florida efforts to deal with 40 years of reuse practice and a movement toward indirect potable reuse. This is the concept where we treat wastewater to a standard whereby it can be put into a waterway upstream of a water supply intake or into the aquifer upstream of wells.  The discussion was extended to a number of discussions about water shortages and solutions for water limited areas.  Florida averages 50-60 inches of rain per year as opposed to the 6-10 inches in areas of the southwest or even 15-20 inches in the Rockies which makes the concept of water limitations seem a bit ludicrous for many, but we rely on groundwater that is recharged by this rainfall for most of our supplies, a lack of topography for storage and definitive wet and dry seasons that do not coincide with use.

The situation is distinctly different in much of the US that relies on surface waters or is just plain water limited.  We have a severe multi-year drought going on in California and huge amounts of groundwater being used for irrigation in many rain-challenged areas.  That is what all those crop-circles are as you fly over the Plains states and the wet.  Where you see crop circles, think unsustainable water supplies.  They are unsustainable because there is no surface water and the recharge for these aquifers is very limited.  Most leakance factors in aquifers is over estimated and hence water levels decline year after year.   Water limited places need answers because agriculture often out-competes water utilities, so in the worst of those areas, there are discussions about direct potable reuse (which occurs in Texas).

Direct and indirect potable reuse are offered as answers which is why this topic was popular at our conference.  A recent 60 Minutes presentation included a tour and discussion of the Orange County Groundwater Replenishment program, where wastewater is treated and injected into the ground for recovery by wells nearer to the coast.  They discussed the process (reverse osmosis, ultraviolet light and peroxide) and they took a drink.  “Tastes like water” was Leslie Stahl’s comment – not sure what she expected it to taste like, but it provides a glimpse into the challenge faced by water utilities in expanding water supplies.   Orange County has been injecting water for many years into this indirect potable reuse project.  The West Coast Basin Barrier Project and several others in California have similar projects.  South Florida has tested this concept 5 times, including one by my university, but no projects have yet been installed.

But until recently, there were no direct potable reuse projects where wastewater is directly connected to the water plant.  But now we have two – both in Texas with a number of potential new projects in the pipeline.  Drought, growth, water competition have all aligned to verify that there many are areas that really do not have water, and what water they do have is over allocated.  A 50 year plan to manage an aquifer (i.e.. to drain it) is not a sustainable plan because there may not be other options.  But Texas is not alone.  Arizona, Nevada, New Mexico, Utah, Colorado, The Dakotas, Kansas Oklahoma and I am sure others have verified water limitations and realize that sustainable economic activity is intrinsically linked to sustainable water supplies.  Conservation only goes so far and in many of these places, conservation may be hitting its limits.  Where your rainfall is limited and/or your aquifer is deep, replenishable resource is not always in the quantities necessary for economic sustainability.  Water supplies and economic activity are clearly linked.

So the unimaginable, has become the imaginable, and we now have direct potable reuse of wastewater.  Fortunately we have the technology – it is not cheap, but we have demonstrated that the reverse osmosis/ultraviolet light/advanced oxidation (RO/UV/AOP) process will resolve the critical contaminant issues (for more information we have a paper we published on this). From an operational perspective, RO membranes, UV and chemical feeds for AOP are easy to operate, but there are questions about how we insure that the quality is maintained.  The technical issues for treatment are well established.  Monitoring is a bit more challenging – the question is what to monitor and how often, but even this can be overcome with redundancy and overdosing UV.

But drinking poop-water? The sell to the public is much more difficult.  It is far easier to sell communities without water on the idea, but the reality we need to plan ahead.  There are no rules.  There are no monitoring requirements, but we MUST insure the public that the DPR water they are drinking is safe.  WE are gaining data in Texas.  California and Texas are talking about regulations.  The University of Miami has been working of a project where they have created a portion of a dorm that makes its own water from wastewater.  Results to come, but the endeavor shows promise.


“If the assumption of all economists, government officials and investors is that the population must increase exponentially, what does that suggest for our future?” was a question asked a few days back.  Did you ponder this at all?  I suggest we should and here is why.  An exponential growth rate assumes a certain percent increase every year.  That means the increase in population is greater the farther out you go.  That doesn’t really make sense except perhaps at one point in Las Vegas (but not anymore).  The economy cannot really expand at a rate greater than the expansion of the population because there is no one to buy the goods or increase the demand, which is why increasing the US population is going to be viewed favorably by all politicians regardless what they say today.  House values do not increase faster than population increase unless they are in a bubble, nor does the stock market really (inflation adjusted).  Your water sales will not increase faster than your system’s population increase for any extended period of time either, so an assumption of ever increasing water sales is likely to be an overestimation sooner as opposed to later.  And then what – you have to raise rates, and keep raising rates to keep up because your demands are too low?

And what if your growth stagnates, or goes backwards as many did in 2009/2010?  That was a severe problem for most entities, causing layoffs and higher prices, pay cuts and deferral of needed improvements, mostly because no one had reserves because people thought the good times would roll on forever.  Layoffs, price hikes, pay cuts and deferral of needed improvements do help society (of course if you had lots of reserves, you weathered the recession without a problem, but too many did not).  Keep in mind the repair, replacement, and maintenance needs, along with ongoing deterioration, do not diminish with time or lack of new customers.  We have relied on new people to add money to solve old as well as new problems for many years.  What is the contingency if growth stops?

So a growth scenario makes us feel better and more confident when we borrow funds.  But if growth does not stop, where is the water to come from?  What are the resources that will be used faster?  Where does the power come from to treat the water or cool the houses?  And the cooling water to cool those power plants?  Even renewable resources are limited – most metals and oil have likely passed their peaks as far as production and water does not always fall consistently.  We have overstressed aquifers and over allocated surface waters, especially in the west.  So while growth makes us feel good financially, we need answers to the growth scenario despite the fact that we may have more funding.  Many resources are not limitless, but an exponential growth pattern ignores this.  Locally growth maybe less of an issue, but society wise?  Maybe a societal problem, or maybe we get into extreme completion with each other.  Some how that doesn’t look like a solution either


Once upon a time, people worked until they died.  But the longer people lived, the more infirmities impacted older people, and the concept of stopping work came into play.  So these folks labored all their lives, put some money away in a safe place, like a bank, where someone else would watch over an manage their money until they needed it.  Then one day, they found out that the banks have gambled and lost on real estate, and their money was gone.  There was no government to bail anyone out.  So the people had to try to go back to work, became beggars and destitute or died.  The government thought this was unfair to those older folks who had worked so hard, but through absolutely no fault of their own, had lost everything.  So the government decided that it would “tax” people a portion of their income, and put it into a retirement system.  People could retire at 65, and of course they were only expected to live another r3 or 4 years.  There were 16 people laying in for every person taking out.  And the government told the banks that they could not gamble with people’s hard earned savings, passed legislation and created an insurance pool to backstop losses by criminal or unethical activity.  All was good and the people were happy.

As time went on some things changed.  For one, people lived more than 3 or 4 years.  The population retirees increased, and the ratio dropped to 1:10 and then to 1:6 ration of retirees:workers, but the “tax” did not go up, but investments were made that increased the pool.  It was called good management.  The government also encouraged people to save money by deferring taxes, which they did, and the banks used it to make money.  All good as long as the investors gambled well.  They gambled so well, they were able to talk the government into undoing the anti-gambling rules from the past, so their pool to invest was twice as much.  And the markets grew and the portfolios grew and the people were happy.

And then it came to pass that the banks again gambled on real estates, and created complicated investment tools to hide the risk, but the risk was exposed and half the money was gone overnight.  And the retired were wondering about jobs again.  But there were no jobs.  And the employed now had fewer jobs.  So less people paid into the system.  And the people were sad.  And mad because they thought they were being protected from the gambling of the past.  They did not understand.

And the government could supply no answers because they had changed the rules and they knew the people would be unhappy, so the government felt there was no choice, so they borrowed money, and bailed out the banks.  And some people were happy.  And some people were concerned about all that debt.  And some people wondered why it was that history could repeat itself and put society at risk.  And some people asked why people who did bad things were not punished.

And none of these questions has been answered.  Good thing that these fairy tales don’t depict anything real right?


Some recent reading led me to the following items that seem to crop up when municipalities have fiscal problems that are not otherwise created by the economy or federal or state government decisions:

Assuming high returns of retained earnings (Orange County, CA)

  • Pension systems that are underfunded (Portland OR, and others)
  • Lack of appropriate financial advisors (many)
  • Assuming growth will be exponential
  • Failure to address deterioration of infrastructure (many)
  • Getting involved in complicated credit swaps and revenues tools involving borrowing (Detroit).
  • Declining use by customers that are economically stressed (many)

Food for thought… or caution.


A Ponzi scheme is an illegal program whereby investors are promised big return son investments in a short period of time, and where the underlying basis for this return is deliberately mis-stated.  We continually find people who perpetrate Ponzi schemes and when they are finally caught, they get put in jail.  For those unsure, a Ponzi scheme is defined as a scheme where the scheme operator says they will pay a high return to its investors from their original investment, but instead uses money from new capital paid to the operator by new investors rather than from profit earned by the operator.  Hence it is a flow through of money from people putting money in to people who are getting out.  To get returns on the investments for the earlier investors, the pool of new people must increase with time, so that there are always more people paying in that there were previously.  It that does not occur, then we have a problem.

What is a retirement system?  A retirement system is a form of deferred compensation used to attract and keep workers, by deferring a portion of their pay 10, 20 30 or 40 years from now.  It is part of the compensation to the employee.  With a retirement system, people pay into a program, where their money is invested.  A retirement system tends to rely on the fact that the number of people paying in increases exponentially so that the actual invested dollars are never touched, instead the new proceeds exceed the monies paid out.  For a pension, plan it assumes your invested dollars remain invested and profitable, and that the revenues from the new people in the system, exceed the monies paid to retirees.  What is the difference?  Well, the retirement system actually supposedly has assets while Ponzi scheme does not.  Otherwise, the systems work similarly – dollars paid in generally go out to others, and there is an assumption that the number or payees increases exponentially (a percentage every year).

So what happens to a pension plan when the number of employees decreases from 6.7 million to 4.4 million over 40 years?  Would you expect there to be a pension plan problem?  And if so why?  And who is at fault?  That is exactly what has happened to federal government employees since 1967.  And many states have seen reductions in the last 20 years as well.  So it is any wonder why these pension systems might be at risk?  The push to privatize services ensures that the basic assumption that the number of payees in a pension plan increases exponentially will be violated, which makes the pension plan vulnerable.  And ho is at fault.  I would suggest the people pushing privatization, who look only at short term consequences as opposed to long-term impacts.  Perhaps this needs to be part of any such discussion going forward.  Just a thought…


In my last blog I outlined the 10 states with the greatest losses since 2006.  Florida was not among them, yet given our legislature’s on-going discussion and hand-wringing with the state run Citizen’s insurance, you would  think we have a major ongoing crisis with insurance here.  Maybe we do, but I will provide some facts.  Citizens,averaged between 1 and 1.5 million policies over the last 8 years.  according the the South Florida SunSentinel, the average person pays $2500 per year for windstorm coverage.  Somehow I think I want that bill because my insurance is about $6000 through my private insurer and when I had Citizens it was $5700/yr.  But I digress.

Let’s assume there is 1.2 million policies over that time paying the #2500/yr. That totals.$3 billion a year in premiums.  That means Citizens should have reserves of $24 billion because they have not paid-out since 2006.  They have $11 billion according to the SunSentinel sources.  So wher eis the rest of the money?  We can assume there are operating expenses.  They pay their executives very well for a government organization.  I am sure they pay the agents as well.  I asked a couple friends in the industry and they indicate that for private companies, about half your premium goes the the agent who writes the policy.  That’s only Citizens.

Let’s assume there are conservatively another 8 million policies in Florida and since many of those are inland, let’s day they average $1500/yr.  If you have it for less, check out your policy!.  That means there is another $12 billion collected each year for a total of $15 billion per year.

Now let’s look at storms.  According to Malmstadt, et al 2010, the ten largest storms 1900–2007, corrected for 2005 dollars are as follows:.

Rank   Storm                         Year        Loss($bn)

1 Great Miami                        1926       129.0

2 Andrew                               1992        52.3

3 Storm                                  1944       35.6

4 Lake Okeechobee               1928       31.8

5 Donna                                1960       28.9

6 Wilma                                  2005       20.6

7 Charlie                                2004        16.3

8 Ivan                                     2004        15.5

9 Storm # 2                            1949        13.5

10 Storm # 4                          1947       11.6

So for all bu the top 9 storms in a 107 year history,the annual receipts exceed the losses for a storm.   The total over the period is $450 billion (adjusted to 2005 dollars)  That means an average of $4 billion per year.  So what is the issue?  Sure a big storm could wipe out the trust fund, but that is what Lloyd;’son London, re-insurers and the ability to borrow funds is all about.

I suggest that the fuzz is really about is this.  Most people do not understand the concept of an insurance pool.  That includes many public officials.  The idea of insurance is to pool resources is to collect huge sums of money so that if something bad occurs, there is the ability to compensate people for their losses.  Insurance is a good thing but individually we hope it is never us that needs to be compensated because that means something bad happened.  But we expect our premiums to pay into that pool, build large pools of money, and have money when you need it. The more people that pay in, the more the  risk is split and lower the likelihood that any individual suffers a loss.  Hence the lower risk should lower premiums.  And people who live in high risk area should pay more than those who don’t.  Flood plains, dry forests, coastal areas, high wind areas, tornado alley, etc are all high risk.  Florida is one, but clearly there are many others,

So Citizens has a pile of money. Most private insurance companies should also, although their money is invested and they expect most of that will not be paid out.  I suspect the concern is a fear that the pile of cash will create a public furor, but that shows a lack of communication and education.  Cash is good.  Lots of it is better.  It’s like running surpluses in government or in your personal savings account. The idea is to have money when you need it.  Running at a point where you never have surpluses guarantees you will have deficits that require cuts in services,and possibly losses of jobs when the economy tanks again.   For insurance, those losses occur when big event hit.  Fortunately those are infrequent, but they have and will happen.  We need the cash pools on hand to protect our citizens just in case.    In the meantime we need some leadership and education of the public.
