My last blog was a discussion about surpluses.  The State of Florida will have a $1.3 billion surplus this year and a host of politically expedient answers for where that money goes (tax cuts, pork projects, projects to help election results), but little mention of replenishing trust funds and reserves that were emptied to balance the budget amid tax cuts from 2010 – 2012.  But perhaps it is not the legislators or their constituents that we should blame for not understanding the need for reserves because the truth is that most people are not used to saving.  A recent article I read noted that 72 percent of Americans live paycheck to paycheck and would have difficulty putting $2000 together if needed.  $2000 is not a lot of money these days – it won’t buy you a transmission for example or a new engine for your car.  It won’t cover first, last and a deposit on a rental.  And it won’t cover the down payment on a house or most cars.  There are people who do not receive enough income to achieve some degree of savings, but not 72% of us.  We have come to perceive that having little savings is normal, but it wasn’t always this way and it is not this way everywhere in the world.  Back in the day, American saved more than they do now.  The reason is not that they had more money (they didn’t) or that they had less to spend money on (as things cost more proportionately).  But it was that “rainy day” they all knew would come and when they would need money.  They had been through depressions, recession and losses of industries (remember those Concord coachmakers did not get a federal bailout in trying to compete with Henry Ford).  They knew that there would be times when they needed to rely on themselves to survive and savings was the key.

There are two major differences from the past.  The most important is the fact is that credit was a lot harder to come by back in the day, so you needed cash for those big purchases.  That has changed dramatically in 50 years.  Today we get advertisements for credit cards – in the mail, instant credit at stores, easy credit for cars, and in the early 2000s, no-money-down-no-income-verification loans on real estate.  The need to save evaporated.  The access to easy credit has eliminated much of the need to save for those big expenses.  We can borrow to acquire them.  If we have a job problem, we borrow against the house or life insurance policy.  These are good backstops that help us maintain our way of life.

At the same time as we are being extended opportunities to secure funds to spend, we are barraged by advertisements and flyers and pitches to spend that money on products and services, many of which we probably don’t need, but are “cool” to have.  We are encouraged to compete to have better “stuff” than the other guy, and make sure we have the newest technology.  We all do it.  Just look at all phones can do, while keeping in mind that the old Bell phone I bought in college still works regardless of the situation and still sounds good.  No cool ringtones however, nor photo capability.  All that means we spend less on “needs” and more on “stuff.” 

Given this backdrop it is no surprise the attitude of decision-makers in government toward revenues and expenses.  Re-education of the public is needed as opposed to rhetoric.  We need to move the public discussion away from the concept of a balanced budget being expenses equal revenues to the correct concept of revenues + reserve expenses = expenses plus savings.  At times you use reserves (and savings =0) while other times reserve expenses are 0, while savings are positive. When big expenses come, borrow, but recurring expenses should not be funded through borrowing (credit).  We should seek to avoid is the desire to cut taxes (akin to cutting our salaries) to bring the budget back into balance that if we run a surplus, or spend it on “stuff.”  Such a system leaves room for those lean times when revenues may fluctuate but expenses do not (or increase).  

Surpluses?

It was not so long ago that we were talking about local and state governments suffering major shortfalls in their revenues as a result of the downturn in the economy.  Cuts were being made to police, fire, education and parks.  Politicians were fussing over the need to cut taxes and cut government expenditures in the process.  Employees lost jobs and benefits were cut.   In a prior blog we discussed the fact that economic upticks and downturns were cyclical, and unlike people, there is a tendency for local and state government policy makers to “hang with the curve” so to speak and have government expenses track the economy as opposed to try to stabilize spending by taking advantage of the ups to create reserves in order to take advantage of the downs.  They ignore the old adage that their grandparents told them – save for a rainy day.  And we don’t recognize those rainy days approaching!  It is not a lot different unfortunately than many citizens who spend when they have money, and are short when they don’t.  We are not a country of savers and it hurts us often.

There is however a major benefit for government to have reserves.  When government has reserves, it can take advantage of lower competition to construct or invest in infrastructure in lean times. There are many examples of governments getting construction done at discounted rates based on timing their projects to economic downturns.  A side benefit is that those governments are spending money at the time when they need to keep people employed.  FDR did this during the Great Depression.  Obama attempted to copy him in 2009 with the AARA monies.  In both cases they may not have invested enough, but both were faced with deficits on the federal level and a Congress that was reluctant to spend. 

The economy has rebounded and state and local governments are starting to run surpluses. The South Florida Sun-Sentinel recently reported that the big “challenge” for the Florida Legislature and many other state and local governments, is they are running surpluses.  Recall the last time the federal government ran a surplus, we got tax cuts that immediately put the feds back in the red because they had not built up any reserves, and won’t even with a balanced budget anytime soon.  Well Florida has $1.3 billion extra on hand and guess what we hear in this election year  – tax cuts, more money for special projects, extended sales tax exemption dates, etc.  Those running for office are thrilled with the surplus because it helps their platform but we hear nothing about restocking the trust funds that were raided during the 2009, 2010 and to some extent the 2011 budgets! 

Expect this to be the norm, and the rhetoric should be troubling to fiscally responsible people.   If we have surpluses, times must be better.  In good times we should be encouraging decision-makers to sock money away in reserves, savings and other solid investments, and at the same time restocking those accounts drained to pay the bills during the down time of the Great Recession.   In Florida, our highway trust fund, environmental trust funds and education funds were drained.  They have not been restocked.  In fact the cuts to most of those programs has not been restored either. The next economic downturn will come – will we be prepared to weather storm by spending our savings as opposed to cutting services which magnifies the impact of residents?

As times get better, utilities owned by local governments should pay particular attention to General Fund revenues.  Many of those General Funds increased contributions from the water and sewer funds to make up the difference in losses of property and sales tax dollars.  That prevented utilities from making investments, or forced them to borrow money to cover investments that might otherwise have been paid for in cash.  Time for the General Fund to pay the utility back!  Time to restock the reserves and time to spend money to catch-up with the deferred maintenance and capital.  Of course the costs are not what they were 3 or 4 years ago, and neither are the interest rates, so we all pay more for the same projects because we could not spend the reserves in the down period.

Utilities should always have significant reserves.  Nothing we do is inexpensive, so having reserves makes it possible to fix things that inevitably go wrong.  Reserves are a part of a well operated, fiscally sound utility. Taking money from the utility during down times hurts both the utility and the local government.  Total reserves diminish of the entity, making it less possible to deal with emergencies, cover the loss of revenues, or take advantage of lower costs for construction projects.  Meanwhile, creating reserves and a pay-as-you-go system for ongoing replacement of pipes and pumps is good business.  It insures that ongoing money is spent to prevent deterioration of the utility system.  The reserves allow for accelerated expenditures when times are tough, prices are down and people need work.  When utilities spend money, it translates to local jobs.  But the only way to do this is make convincing argument of the benefits of reserves and spending.  

SEA LEVEL RISE AND FLOOD PROTECTION

Regardless of the causes, southeast Florida, with a population of 5.6 million (one-third of the State’s population), is among the most vulnerable areas in the world for climate change due its coastal proximity and low elevation (OECD, 2008; Murley et al. 2008), so assessing sea level rise (SLR) scenarios is needed to accurately project vulnerable infrastructure (Heimlich and Bloetscher, 2011). Sea level has been rising for over 100 years in Florida (Bloetscher, 2010, 2011; IPCC, 2007).  Various studies (Bindoff et al., 2007; Domingues et al., 2008; Edwards, 2007; Gregory, 2008; Vermeer and Rahmstorf, 2009; Jevrejeva, Moore and Grinsted, 2010; Heimlich, et al. 2009) indicate large uncertainty in projections of sea level rise by 2100. Gregory et al. (2012) note the last two decades, the global rate of SLR has been larger than the 20th-century time-mean, and Church et al. (2011) suggested further that the cause was increased rates of thermal expansion, glacier mass loss, and ice discharge from both ice-sheets. Gregory et al. (2012) suggested that there may also be increasing contributions to global SLR from the effects of groundwater depletion, reservoir impoundment and loss of storage capacity in surface waters due to siltation.

Why is this relevant?  The City of Fort Lauderdale reported last week that $1 billion will need to be spent to deal with the effect of sea level rise in Fort Lauderdale alone.  Fort Lauderdale is a coastal city with canals and ocean property, but it is not so different from much of Miami-Dade County, Hollywood, Hallandale Beach, Dania Beach and host of other coastal cities in southeast Florida.  Their costs may be a harbinger of costs to these other communities. Doing a “back of the napkin”  projection of Fort Lauderdale’s cost for 200,000 people to the additional million people in similar proximity to Fort Lauderdale means that $5 billion could easily be spent over the next 100 years for costal impoundments like flap gates, pumping stations, recharge wells, storm water preserves, exfiltration trenches and as discussed in this blog before, infiltration galleries. Keep in mind that would be the coastal number and we often ignore ancillary issues.  At the same time, an addition $5 to 10 billion may be needed for inland flooding problems due to the rise of groundwater as a result of SLR.

The question raised in conjunction with the announcement was “is it worth it?”  I suggest the answer is yes, and not just because local politicians may be willing to spend money to protect their constituents.  The reality is that $178 billion of the $750 billion economy of Florida, and a quarter of its population, is in the southeast. With nearly $4 trillion property values, raising a few billion for coastal improvements over 100 years is not an insurmountable task.  It is billions in local engineering and construction jobs, while only impacting taxpayers to the tune of less than 1/10 of a mill per year on property taxes. This is still not an insurmountable problem.

I think with good leadership, we can see our way.  However, that leadership will need to overcome a host of potential local community conflicts as some communities will “get more” than others, yet everyone benefits across the region.  New approaches to working together will need to be tried.  But the problem is not insurmountable, for now…

Detroit – Feast to Famine – it there a Lesson to Learn?

I have said before in this blog that my Dad’s family were born and raised in Detroit – not the suburbs, in the City, about a mile north of Tiger Stadium.  My great-grandfather was a butcher.  His sons all became butchers, so my Dad grew up around the butcher shop as a kid.  It was the Depression, but because of the shop, my Dad had food on his table.  My Great-grandmother managed the money, and acquired a number of properties in the area of 13th and Magnolia that the sons, and extended families would eventually move to.  It was a solution to the difficulties outside the shop.  Family was the means to survive the hard times of the Depression. 

Of course Detroit was a booming city – over 100 auto companies were in Detroit at the turn of the last century, and the City was becoming the center of a new mode of transportation – the automobile.  Henry Ford developed the assembly line to allow everyone to own a car, furthering the status of the City.  As the twenties developed, Detroit and Chicago competed to become the “jewel” of the Midwest.  Elaborate stone buildings, expanding infrastructure for roads, trains, water, sewer and storm water were all centerpieces of pride in the City.  Employment and incomes were high, worker benefits were good, the workforce was highly skilled and education was good. Profits were good and the auto industry was Detroit-centric. Detroit was a vibrant City in the first 50 years of the last century. 

Scroll ahead 60 years and how the city has fallen.  The City has lost a million people.  It has $18 billion in debt, and is collecting $0.3 billion less in revenues since 2008.  The tax base has been decimated.  Houses can be purchased for minimal prices.  Churches have been abandoned.  Crime is high.  Employment is down, unemployment remains above the state and national average.  Poverty is up, incomes are down.  Huge areas must be served but serve no one or only a very few.   The City filed the highest profile bankruptcy for a municipality ever.

The television show Low Down Sun last summer provided a graphic look at the City – blocks of the City devoid or mostly so of housing or other buildings, schools no longer in use, roads in disrepair, classic stone buildings with the windows broken out.  You can see what the City was, and the haunting view of the City today are a stark reality.  To add insult to injury, the Sun-Sentinel wrote a recent article about how people are making money doing tours of abandoned buildings in Detroit, or how farming is occurring in the City limits. 

So if Detroit failed, why not Cleveland, Akron, Pittsburgh, St. Louis, Cincinnati or virtually any other large, older Midwestern industrial city?  Sadly many of these cities have lost the industries that made them famous and provided jobs and a stable tax base and incomes.  Many of these cities are also stressed, much as we found Birmingham was.  There are many arguments for what precipitated these losses:  unions, shifts in population, outsourcing offshore, competition within the US, changes in consumer preferences, technology…… the list goes on.  But the reality is it doesn’t matter why, the City must deal with the reality that is.  We all look at Detroit and its recent bankruptcy filings.  Maybe looking at Detroit allows us to feel better about our situations, but we need to learn the lesson from Detroit, Birmingham, Cleveland and others who filed for bankruptcy.  We need to look back to determine where the decisions were that created the issues.  Was it expanding to fast, poor economic assumptions, failure to manage finances better, political failures, failure to raise revenues/taxes/water fees, or failure to maintain or replace infrastructure?  Rarely is it corruption, so it is people trying to do well but failing in their jobs.  The question is why? 

I would start with training.  We need to train our public managers better, but MPA and MBA schools are not teaching about these failures.  In part it may be because we tend to teach positive lessons, versus negative ones, but they would be useful case study of the potential challenges.  In a prior blog I noted that the biggest challenge for government managers is managing in lean times.  Often lean times can be overcome by saving money as fund balances and investing (well), but long-term downturns like Detroit, Cleveland and other cities have experienced cannot be corrected this way.  There are major policy implications that must be overcome. 

From a utility perspective it is important to note that the economic difficulties are not limited to cities and counties but utilities are subject to long-term declines as well.  The problem is particularly acute in industrial communities where a large industry (think mills in the mid-Atlantic states) move away and leave water and wastewater facilities at far less capacity than they were designed for. Small systems may be especially at risk.

As an industry we need to learn from these failures.  We should study the difficult times to determine how the problems can be avoided.  The need to figure out how to manage funds better, deal with customer losses, and define strategies to overcome losses.  If anyone has some thoughts, please respond to the blog, but doesn’t this sound like a research project in the making?

INVESTING IN INFRASTRUCTURE

When we ask what the biggest issues facing water and sewer are in the next 20 years, the number one answer is usually getting a handle on failing infrastructure.  Related to infrastructure is sustainability of supplies and revenue needs.  Resolving the infrastructure problem will require money, which means revenues, and overcoming the resistance to fully fund water and sewer system by local officials, the potential for significant costs or shortfalls for small, rural systems and the increasing concern about economically disadvantaged people. 

The US built fantastic infrastructure systems in the mid-20th century that allowed our economy to grow and for us to be productive.  But like all tools and equipment, it degrades, or wears out with time.  Our economy and our way of life requires access to high quality water and waste water. So this will continue to be critical. 

ASCE and USEPA have both noted the deteriorated condition of the water and wastewater systems.  In the US, we used to spend 4% of the gross GNP on infrastructure.  Currently is it 2%.  Based on the needs and spending, there is a clear need to reconstruct system to maintain our way of life.  This decrease in funding comes at a time when ASCE rates water and wastewater system condition as a D+ and estimates over $3 trillion in infrastructure investment will be needed by 2020.  USEPA believes infrastructure funding for water and sewer should be increased by over $500 billion per year versus the proposed federal decrease of similar amounts or more. 

Keep in mind much of what has made the US a major economic force in the middle 20th century is the same infrastructure we are using today. Clearly there is research to indicate there is greater need to invest in infrastructure while the politicians move the other way.  The public, caught in the middle, hears the two sides and prefers less to pay on their bills, so sides with the politicians as opposed to the data.  Make no mistake, our way of life results from extensive, highly efficient and economic infrastructure systems. 

In many ways we are victims of our own success.  The systems have run so well, the public takes them for granted.  It is hard to make the public understand that our cities are sitting on crumbling systems that have suffered from lack of adequate funding to consistently maintain and upgrade.  Public agencies are almost always reactive, as opposed to pro-active, which is why we continuously end up in defensive positions and at the lower end of the spending priorities. So we keep deferring needed maintenance. The life cycle analysis concepts used in business would help. A 20 year old truck, pump, backhoe, etc. just aren’t cost effective to operate and maintain.

Another part this problem is that people have grown used to the fact that water is abundant, cheap, and safe. Open the tap and here it comes; flush the toilet and there it goes, without a thought as to what is involved to produce, treat and distribute potable water as well as to collect, treat, and discharge wastewater.

Water and Sewer utilities are being funded at less than half the level needed to meet the 30 year demands.  Meanwhile relying on the federal government, which is trying to reduce funding for infrastructure for local utilities is not a good plan either. We need education, research and demonstrations to show those that control funding of the needs. The education many be the toughest part because making the those that control funding agree to increase rates carries a potential risk to them personally.  But there are no statues to those that don’t raise rates – only those with vision.  We need to instill vision in our decision-makers.

Oil Energy and Utilities

Back during the dark days of the late-1970s, when America was being held hostage by Middle East oil interests, the Department of Energy was created, ostensibly to free our economy from the dependence on foreign oil and all that trappings that go with it.  It was a noble goal – the American economy could grow without the risks posed by foreign governments.  Thirty five years later, could we finally be reaching that goal? 

Interesting the often criticized billions of energy company subsidies of the Bush era do not appear to be responsible for solving the issue.  Nor are the prior efforts to subsidize or otherwise encourage investments before.  The energy subsides since 2000 do not appear to be the reason, but the arctic wilderness did not need to be disturbed either.  The success had nothing to do with any of it, but instead a series of private risk takers to a gamble on an unproven technology, to make great strides – fracking.

Based on the success of the development of fracking for natural gas, we have made major improvements.  But it is not just fracking, as many power plants are or have been rehabilitated to convert away from oil and coal to cleaner burning natural gas, thereby developing the market for natural gas.  Local governments have been migrating their fleets to natural gas for years – natural gas can use the same engine with an $8000 conversion kit that allows automobiles to run on both.  The conversions have made the demand for natural gas greater, making the investments needed to frack, more profitable.  The US has significant reserves of natural gas, and fracking has made it easier to capture this resource.  The benefit of natural gas is that the demand for oil is down, creating a glut of oil on the market and a decrease in price (at least for now).

But the question that has been left unanswered is what the domino effect of natural gas is.  Certain advertisements will argue there is 200 years of natural gas available for the US so we don’t need to worry about energy.  Others will argue that only 10-15% of that supply is actually recoverable (it should be noted that this assumes current methods), which is a far shorter horizon.  But in either case, natural gas in the ground is not a renewable resource so the question must be asked – does the fracking boom interfere with investment in truly renewable resources? 

Since 2000, Washington has invested heavily in renewable resources – wind, solar and to an extent waves.  Some energy companies like NextEra have been investing heavily in wind and solar power (they are the biggest investors in renewable power in the US), so what of these truly renewable investments?  Will the rush to frack turn resources away from truly renewables?  Or will renewable continue to be a small fraction of energy demands for the near future?  The question remains unanswered for now.

The bigger question for utilities is whether fracking will divert money away from plans for renewable efforts like digester gas capture, solar cells and wind power at reservoirs and the like that utilities are using to help reduce power purchases.  Will it impact utility efforts to become self-sufficient energy consumers like East Bay MUD?  You see the economy has few favorites.  Government can create favorites, by subsidizing products that would otherwise be too expensive like PV panels. The benefit of subsides can be to reduce costs of emerging technologies that may never otherwise see widespread use.  Subsidizing renewables fit this mode.

Utilities should be concerned that the rush to frack pulls money away from their plans for renewable power.  As the feds look to reduce their contributions to water and wastewater infrastructure, public money to energy does not appear to be decreasing.  And unlike publically owned water and sewer systems, private investment in energy is increasingly available as a result of the potential profits that can be made.  The diversion of funds may decrease prospects for funding water and sewer utility options, especially if interest rates begin to rise.  The Federal Reserve Bank’s concern about rising interest rates was manifested earlier this year when interest rate increased, housing sales decreased immediately.

Of course the issue of fracking goes beyond the potential to disrupt monies for renewable energy.  There are questions about the practice of fracking include water quality impacts, causing earthquakes, land subsidence, etc., issue that have yet to be resolved.  Keep an eye out for a risk assessment that AWWA and others will be involved with to look at these risks.  

Rural Utilities Part 2

In the last blog I talked about the challenge to rural utilities, many of which serve relatively few people and have used federal monies to pay for a lot of their infrastructure.  In this blog we will take a look at the trends for community water systems which are defined as systems that serve at least 15 service connections or serve an average of at least 25 people for at least 60 days a year. EPA breaks the size of systems down as follows:

  • Very Small water systems serve 25-500 people
  • Small water systems serve 501-3,300 people
  • Medium water systems serve 3,301-10,000 people
  • Large water systems serve 10,001-100,000 people
  • Very Large water systems serve 100,001+ people

Now let’s take a look at the breakdown (from NRC 1997).  In 1960, there were about 19,000 community water utilities in the US according to a National Research Council report published in 1997.  80% of the US population was served.  in 1963 there were approximately 16,700 water systems serving communities with populations of fewer than 10,000; by 1993 this number had more than tripled—to 54,200 such systems. Approximately 1,000 new small community water systems are formed each year (EPA, 1995). In 2007 there were over 52,000 community water systems according to EPA, and by 2010 the number was 54,000.  85% of the population is served. So the growth is in those small systems with incidental increases in the total number of people served (although the full numbers are more significant).

b Percentage is relative to the total population served by community water systems, which is less than the size of the U.S. population as a whole.

SOURCES: EPA, 1994; Public Health Service, 1965.

 

Updating these numbers, there are over 54,000 systems in the US, and growth is almost exclusively in the very small sector.  93% are considered to be small or very small systems—serving fewer than 10,000 people. Even though these small systems are numerous, they serve only a small fraction of the population. Very small systems, those that serve 3,300 people or fewer make up 84 percent of systems, yet serve 10 percent of the population.  Most critical is the 30,000 new very small systems that serve only 5 million people (averaging 170 per system).  In contrast, the very large systems currently serve 45% of the population.  Large plus very large make it 80%.  The 800 largest systems (1.6%) serve more than 56 percent of the population. 900 new systems were added, but large systems served an additional 90 million people.

What this information suggests if that the large and very large sector has the ability to raise funds to deal with infrastructure needs (as they have historically), but that there may be a significant issue for smaller, rural system that have grown up with federal funds over the past 50 years.  As these system start to come to the end of their useful life, rural customers are in for a significant rate shock. Pipeline average $100 per foot to install.  In and urban area with say, 60 ft lots, that is $3000/household.  In rural communities, the residents may be far more spread out.  As an example, a system I am familiar with in the Carolinas, a two mile loop served 100 houses.  That is a $1.05 million pipeline for 100 hours or $10,500 per house.  With dwindling federal funds, rural customers, who are already making 20% less than their urban counterparts, and who are used to very low rates, that generally do not account for replacement funding, will find major sticker shock. 

This large number of relatively small utilities may not have the operating expertise, financial and technological capability or economies of scale to provide services or raise capital to upgrade or maintain their infrastructure.  Keep in mind that small systems have less resources and less available expertise.  In contrast the record of large and very large utilities, EPA reports that 3.5 percent of all U.S. community water systems violated Safe Drinking Water Act microbiological standards one or more times between October 1992 and January 1995, and 1.3 percent violated chemical standards, according to data from the U.S. Environmental Protection Agency (EPA).. 

EPA and professionals have long argued that centralized infrastructure for water and sewer utilities makes sense form an economy of scale perspective.  Centralized drinking water supply infrastructure in the United States consists dams, wells, treatment plants, reservoirs, tanks, pumps and 2 million miles of pipe and appurtenances.   In total this infrastructure asset value is in the multi-trillion dollar range.  Likewise centralized sanitation infrastructure in the U.S. consists of 1.2 million miles of sewers and 22 million manholes, along with pump stations, treatment plants and disposal solutions in 16,024 systems.  It is difficult to build small reservoirs, dams, and treatment plants as they each cast far more per gallon to construct than larger systems.  Likewise operations, despite the allowance to have less on-site supervision, is far less per thousand gallons for large utilities when compared to small ones.  The following data shows that the economy-of-scale argument is true:

  • For water treatment, water distribution, sewer collection and wastewater treatment, the graphics clearly demonstrated the economy-of-scale of the larger utility operations versus small scale operations (see Figures 2-5). 
  • The administrative costs as a percentage of the.total budget parameter also demonstrated the economy-of-scale argument that larger utilities can perform tasks at a lesser cost per unit than the smaller utilities (see Figure 6).

Having reviewed the operations costs, the next step was to review the existing rates.  Given the economy-of-scale apparent in Figures 2 to 6, it was expected that there would be a tendency for smaller system to have higher rates.  Figures 2-6 demonstrate this phenomena. 

So what to do?  This is the challenge.  Rate hikes are the first issue, a tough sell in areas generally opposed to increases in taxes, rates and charges and who use voting to impose their desires.  Consolidation is anothe5r answer, but this is on contrast to the independent nature of many rural communities.  Onslow County, NC  figured out this was the only way to serve people efficiently 10 years ago, but it is a rougher sell in many, more rural communities.  Infrastructure banks might help, the question is who will create them and will the small system be able to afford to access them.  Commercial financing will be difficult because there is simply not enough income to offset the risk.  The key is to start planning now for the coming issue and realize that water is more valuable than your iPhone, internet, and cable tv.  In most cases we pay more for each of them than water (see Figure 7).  There is something wrong with that…

As 2014 is only a month away, expect water and sewer infrastructure to become a major issue in Congress.  While Congress has failed to pass budgets on-time for many years, already there are discussions about the fate of federal share of SRF funds.  The President has recommended reduction in SRF funds of $472 million, although there is discussion of an infrastructure fund, while the House has recommended a 70% cut to the SRF program.  Clearly the House sees infrastructure funding as either unimportant (unlikely) or a local issue (more likely).  Past budgets have allocated over $1.4 billion, while the states put up a 20% match to the federal share.  A large cut in federal funds will reverberate through to local utilities, because many small and medium size utilities depend on SRF programs because they lack access to the bond market.  In addition, a delay in the budget passage due to Congressional wrangling affects the timing of SRF funds for states and utilities, potentially delaying infrastructure investments. 

This decrease in funding comes at a time when ASCE rates water and wastewater system condition as a D+ and estimates over $3 trillion in infrastructure investment will be needed by 2020.  USEPA notes that the condition of water and wastewater systems have reached a rehabilitation and replacement stage and that infrastructure funding for water and sewer should be increased by over $500 billion per year versus a decrease of similar amounts or more.  Case Equipment and author Dan McNichol have created a program titled “Dire Straits:  the Drive to Revive America’s Ailing Infrastructure” to educate local officials and the public about the issue with deteriorating infrastructure.  Keep in mind much of what has made the US a major economic force in the middle 20th century is the same infrastructure we are using today. Clearly there is technical momentum to indicate there is greater need to invest in infrastructure while the politicians move the other way.  The public, caught in the middle, hears the two sides and prefers less to pay on their bills, so sides with the politicians as opposed to the data. 

Local utilities need to join the fray as their ability to continue to provide high quality service.  We need to educate our customers on the condition of infrastructure serving them.  For example, the water main in front of my house is a 50 year old asbestos concrete pipe that has broken twice in the past 18 months. The neighborhood has suffered 5 of these breaks in the past 2 months, and the City Commission has delayed replacement of these lines for the last three years fearing reprisals from the public.  Oh and the road in front of my house is caving in next to where the leak was.  But little “marketing” by the City has occurred to show the public the problem.  It is no surprise then that the public does not recognize the concern until service is interrupted.  So far no plans to reinitiate the replacement in front of my house.  The Commission is too worried about rates.

Water and sewer utilities have been run like a business in most local governments for years  They are set up as enterprise funds and people pay for what they use.  Just like the private sector.  Where the process breaks down is when the price is limited while needs and expenses rise.  Utilities are relatively fixed in their operating costs and I have yet to find a utility with a host of excess: workers.  They simply do not operate in this manner.  Utilities need to engage the public in the infrastructure condition discourse, show them the problems, identify the funding needs, and gain public support to operate as any enterprise would – cover your costs and insure you keep the equipment (and pipes) maintained, replacing them when they are worn out.  Public health and our local economies depend on our service. Keep in mind this may become critical quickly given the House commentary.  For years the federal and state governments have suggested future funding may not be forthcoming at some point and that all infrastructure funding should be local.  That will be a major increase in local budgets, so if we are to raise the funds, we need to solicit ratepayer support.  Now!  

Why Build Green?

In the field of engineering, the concept of sustainability refers to designing and managing to fully contribute to the objectives of society, now and in the future, while maintaining the ecological, environmental, and economic integrity of the system.  Most people would agree that structures such as buildings that have a lifespan measured in decades to centuries would have an important impact on sustainability, and as such, these buildings must be looked at as opportunities for building sustainably. When people think about green buildings, what generally comes to mind is solar panels, high efficiency lighting, green roofs, high performance windows, rainwater harvesting, and reduced water use.  This is true, but building green can be so much more.

The truth is that the built environment provides countless benefits to society; but it has a considerable impact on the natural environment and human health (EPA 2010). U.S. buildings are responsible for more carbon dioxide emissions annually than those of any other countries except China (USGBC 2011). In 2004, the total emissions from residential and commercial buildings were 2,236 million metric tons of carbon dioxide (CO2), more than any other sector including the transportation and industrial sectors (USGBC 2011). Buildings represent 38.9% of U.S. primary energy use,72% of U.S electricity consumption (and 10% worldwide), 13.6% of all potable water, and 38% of all CO2 emissions (USGBC 2011).  Most of these emissions come from the combustion of fossil fuels to provide heating, cooling, lighting, and to power appliances and electrical equipment (USGBC 2011). Since buildings have a lifespan of 50 to 100 years during which they continually consume energy and produce carbon dioxide emissions, if half of the new commercial buildings were built to use only 50 percent less energy, it would save over 6 million metric tons of CO2 annually for the life of the buildings. This is the equivalent of taking more than one million cars off the roads each year (USGBC 2011).

The United States Green Building Council (USGBC) expects that the overall green building market (both non-residential and residential) to exceed $100 billion by 2015 (McGraw Hill Construction 2009).  Despite the economic issues post 2008, it is expected that green building will support 7.9 million U.S. jobs and pump over $100 million/year into the American economy (Booz Allen Hamilton, 2009). Local and state governments have taken the lead with respect to green building, although the commercial sector is growing.

Green building or high performance building is the practice of creating structures using processes that are environmentally responsible and resource efficient throughout a building’s life cycle, from site to design, construction, operation, maintenance, renovation, and deconstruction (EPA 2010). High performance building standards expand and complement the conventional building designs to include factors related to: economy, utility, durability, sustainability, and comfort. At the same time, green building practices are designed to reduce the overall impact of the built environment on human health and use natural resources more responsibly by more efficiently using energy, water, and other resources, while protecting occupant health and improving employee productivity.

High Performance Buildings are defined by incorporating all major high performance attributes such as energy efficiency, durability, life-cycle performance, natural lighting, and occupant productivity (EPA 2010). High performance buildings are constructed from green building materials and reduce the carbon footprint that the building leaves on the environment. A LEED-certified green building uses 32% less electricity and saves around 30% of water use annually (USGBC 2011). Building owners know that there is a return on investment of up to 40% by constructing a green building as a result of savings to energy and water (NAU 2012).

The cost per square foot for buildings seeking LEED Certification falls into the existing range of costs for buildings not seeking LEED Certification (Langdon, 2007).  An upfront investment of 2% in green building design, on average, results in life cycle savings of 20% of the total construction costs – more than ten times the initial investment (Kats, 2003), while building sale prices for energy efficient buildings are as much as 10% higher per square foot than conventional buildings (Miller et al., 2007). At the same time, the most difficult barrier to green building that must be overcome includes real estate and construction professionals who still overestimate the costs of building green (World Business Council, 2008).

New data indicates that the initial construction cost of LEED Certified buildings can sometimes cost no more than traditional building practices.  A case study done by the USGBC showed that the average premium for a LEED certified silver building was around 1.9% per square foot more than a conventional building.  The premium for gold is 2.2% and 6.8% for platinum.  These numbers are averaged from all LEED-registered projects, so the data is limited, but demonstrates that in some cases it does not cost much extra to deliver a LEED certified project which greatly improves the value of the building and lowers operating costs (Kuban 2010).  The authors’ experience with the Dania Beach nanofiltration plant indicated the premium was under 3% to achieve LEED-Gold certification compared to standard construction.

So the question is, why don’t we see more green buildings?  We know water plants can be green (Dania Beach Nanofiltration Plant), but that was the first nanofiltration plant in the world to be certified Gold.  The SRF programs prioritize green infrastructure – so why do more people not pursue them?  It may be an education process.  Or maybe the market just has not caught up.  CIties and states are leading the way here.  Utilities may want to look at this as well.Image

Communication in to Often Under-rated with Utilities

Communicating effectively in both written form and public speaking is critical for the success of the utility.  I have been reading several books on leadership and communication remains an ongoing issue throughout.  We see many schools trying to incorporate this into the engineering curriculum, but that leaves far too many outside the training “program.”  The problem is that many people think they communicate well, when in fact they do not.  Nothing is  more of a reality check than college students, too many of which write in “text message form” as opposed to real written words.  Presenting utility concepts and ideas to different audiences is an integral part of the profession and unfortunately the technical nature of many of our issues requires technical people to communicate concepts to non-technical audiences.  This s far more difficult than it appears, which is part of why the message may be lost.  .Knowing this fact, aspiring utility employees must become familiar with using visual aids and computer-based tools to convey the important design details, so that, the client, regulators, politicians, the public and even other engineers can envision what the final product will look like and evaluate their ability to successfully execute the project. 

We tell our students that technical communication for civil engineers is essential to the profession and is a prerequisite for a successful engineering career. It assists in conveying information, serves as a thought process tool, and is arguably just as essential as excellent analytical or computational skills. For some, writing well comes naturally, for others, it can be a struggle. The difference can be experience, confidence, and proper planning. Planning makes writing easier. A good place to start would be to make an outline of topics to adequately cover the necessary content and in the appropriate order that allows the reader to follow along in a logical fashion. Of course too many of them resist outlines and read very little.  

Reading and writing go hand in hand.  If you read a lot, you have a better chance of being a good writer than those o do not.  The saving grace of the vampire books, Hunger Games, Game of thrones and 50 Shades series is that someone is actually reading the books. That is a first step.  Of course the news is another matter.  History, of course no so much.  For utility folks, it is technical materials that must be read, digested and conveyed to the ratepayers.  People are naturally suspicious of those they cannot understand, a huge barrier for the industry to overcome. I remind our students than when the general public is asked what engineers do, more than half answer:  drive trains.  Wow.  the disconnect!

It is important to avoid overly long documents with too much technical detail, jargon or specialized terms, distractions and tangents.The consequences of poor communications clearly justify the amount of time and effort required to write well because, for example, the written word in a document is permanent; therefore, the bad impression left with the reader of sloppy work can be extremely damaging.  We need to engage the public in a positive way.  Communication needs to be a more robust goal for all of us than it currently is to engender that needed support.
