Local utilities are among the largest power users in their communities.  This is why power companies make agreements with utilities at reduced cost if the utilities will install backup power supplies.  The peak power generation capacity as well as backup capacity is at the local utilities and other large users.  Power companies can delegate this capital cost to large users without the investment concerns.  It works for both parties.  In addition, power companies spend effort to be more efficient with current power supplies, because recovering the costs for new, large plants is difficult, and in ways, cost prohibitive.  Hence small increment options are attractive, especially when they are within high demand areas (distributed power).  The use of localized wind, solar and on-site energy options like biogas are cost effective investments if sites can be found.  That is where the utilities come in.  Many utilities have sites.  Large water utilities may have large reservoirs and tank sites that might be conducive to wind or solar arrays.  Wind potential exists where there are thermal gradients or topography like mountains.  Plant sites with many buildings and impervious areas could also be candidates for solar arrays and mini-wind turbines.  Wastewater plants are gold mines for digester gas that is usually of high enough quantity to drive turbines directly.  So utilities offer potential to increase distributed power supplies, but many water/wastewater utilities lack the expertise to develop and maintain these new options, and the greatest benefit is really to power companies that may be willing to provide as much money in “rent” to the utilities as they can save.   Power entities obviously have the expertise and embedded experience to run distributed options optimally.  So why don’t we do this?

I would speculate several reasons.  First, the water/wastewater utilities have not really considered the option, and if they do there is the fear of having other folks on secure treatment sites.  That can be overcome.  The power entities have not really looked at this either.  The focus in the power industry is to move from oil-based fuels to natural gas to accumulate carbon credit futures, the potential for lower operating costs and better efficiency of current facilities to reduce the need for capital investments.  Power entities operate in a tight margin just like water/wastewater utilities do so saving where you can is a benefit.  There are limited dollars to invest on both sectors and political and/or public service commission issues to overcome to invest in distributed power options at water/wastewater facilities. 

But a longer-term view is needed.  While fossil fuels have worked for us for the last 100 years, the supply is finite.  We are finding that all that fracking might not give us 200 years, but more like 20-40 years of fuel.  We have not solved the vehicle fuel issue and fossil fuels appear to be the best solution for vehicles for the foreseeable future which means they will compete directly with power demands.  Natural gas can be used for vehicles fairly easily as evidenced by the many transit and local government fleets that have already converted to CNG. 

The long-term future demands a more sustainable green power solution.  We can get to full renewable power in the next 100 years, but the low hanging fruit need to be implemented early on so that the optimization of the equipment and figuring out the variables that impact efficiency can be better understood than they are now.  For example, Leadville, CO has a solar array, but the foot of snow that was on it last September didn’t allow it to work very well.  And solar arrays do use water to clean the panels.  Dirty panels are nowhere near as efficient as clean ones.  We need to understand these variables.

Area that are self sufficient with respect to power will benefit as the 21st century moves forward.  There are opportunities that have largely been ignored with respect to renewable power at water and wastewater facilities, and with wastewater plants there is a renewable fuel that is created constantly.  Wastewater plants are also perfect places to receive sludge, grease, septage, etc which increase the gas productions.  There are examples of this concept at work, but so far the effort is generally led by the wastewater utilities.  An example is East Bay Municipal Utility District (Oakland, CA) which produces 120% of its power needs at its wastewater plant, so sells the excess power back to the power company.  There are many large wastewater plants that use digester gas to create power on-site to heat digesters or operate equipment.  Others burn sludge in on-site incinerators to produce power.  But so far the utilities are only reducing their cost as opposed to increasing total renewable power supplies.  A project is needed to understand the dynamics further.  If you are interested, email me as I have several parties wishing to participate in such a venture. 


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!  


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


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.


Graduation is two weeks away for students in the Fall semester.  The good news is that unemployment is down which means more students may find jobs.  We see my students, civil engineers, nearly fully employed for the second straight semester.  That is a good sign that economy is bouncing back. 

Many are being hired by utilities and contractors.  The utilities are starting to spend money after several years of lean revenues.  Unfortunately many of these utilities were lean because their local governments have increased general fund contributions to reduce tax burdens of residents.  Reducing tax burdens by moving more money from utilities to general funds hits the utility twice – infrastructure improvements get delayed and catchup on deferred maintenance mean the hit is double the pay as you go policy.  It is no surprise that our infrastructure condition continues to deteriorate when funds are diverted for other purposes.  Hopefully the trend will reverse, but I am not optimistic. 

Contractor hiring is more interesting.  It seems that contractors are having many of the same issues as utilities have talked about for a number of years:  an aging workforce in the upper levels of the organization.  However the contractors are seeing that young engineers have a skill set not currently existing in many contractor organizations.  Contracting in lean times is a limited profit margin business.  Competing for low bid contracts further limits profits.  However when 40% of the cost for construction is often associated with materials, and 20-25% of materials may be wasted, finding a way to be more efficient can save a lot of money.  Engineers know software and some schools, like FAU, have their students use 3 dimensional (3D) BIM software for their design projects.  The BIM software allows contractors to merge drawings into 3 dimensions, finding conflicts, solving them early and identifying means to reduce materials.  For example, many pieces could be cut out of gypsum board, but often only one is cut.  The rest is tossed.  Saving big on materials creates added profits at the same price.  The benefit is seen as being well worth the cost to contractors.  As more contractors move this direction, more engineers will the hired; a good trend.

The engineering profession should benefit from this change.  As contractors hire engineers, there is the potential for better communication between engineers on contractor teams and design engineers.  The only question is getting the engineering community to adopt the same kind of attitude toward the new software tools like 3D software.  At present, far too many engineers do not believe the risks are reduced sufficiently by the costs of the software.  But adopting new methods for design will help communication with contractors and other engineers.  That communication has a benefit in saving dollars and limiting the potential for claims against design firms when conflicts are found in the design drawings.  We find that establishing a partnering mentality on projects fosters a better working relationship.  Great things can be accomplished. 


I worked for a while in rural North Carolina.  I confronted two issues there that are instructive. The first was that many people did not value education because for the most part they expected to do menial labor activities on farms or in construction.  They figured they did not need much education. That was the adults!!  Kids in such situations have little hope of succeeding academically when their parents do not value education, and in some cases may either ridicule their efforts or at least be un-supportive of same.  The second was the idea that the “guys” who could not work anywhere but needed a job should get a job with the “city.”  Wow, I’d like to hope we are past both of these, but the Census statistics clearly show we are not on the education part at least.  Census data indicates that when you look at educational spending, per capita income, graduation rates and unemployment rates, the bottom 10 states are:

North Carolina

Tennessee

South Carolina

Nevada

Kentucky

Alabama

Mississippi

West Virginia

Louisiana

Arkansas

All but Nevada (#35) are in the bottom 12 in spending per student and the academic achievement of their students appears to indicate the efforts are inadequate.  For the most part these are largely rural southern states, so my experiences 25 years ago may be no different now. Kids see low wages, higher unemployment and figure what does education get them?, so it perpetuates the myth of their parents. Or maybe it is not a myth afterall?  Interesting these are primarily the states with the highest number of students in poverty, lead my Mississippi’s whopping 71%.  All are over 50%. All among the states with highest rates of food stamp recipients.  So the kids are living the low income expectations.

Where I currently am I periodically interact with inner-city kids. No surprise, there is a similar mindset – the kids see their future as minimum wage jobs that require no skills, or the expectation that the violence of their surroundings will catch up to them (crime, welfare, etc).  None of their expectations require education (although it is surprising how sophisticated their understanding of all of these issues are), so many do not pursue learning with vigor after 10 or 12 years old. Skipping school, suspensions, lower scores and grades are common.  Too many parents do not encourage their kids and the mindset creates deterioration of urban schools. Periodically I have students who are actively trying to escape the stereotypes, but they will confirm that school is not a priority for far too many  inner city kids.  No surprise they learn this from their parents who are often underemployed or lack good employment because they never obtained the education needed to escape the neighborhood. 

In both cases the problem is lack of employment expectations. The kids look around them and figure they have no hope of escaping the minimum wage, limited skill jobs. Unfortunately our job resurgence indicates that these are the jobs we are producing the most on far too many areas.  In the past 2 years, the State of Florida suggests that 90% of the jobs created are minimum wages jobs.  The local casinos are advertising for hundreds of jobs – as waiters, kitchen help, maintenance, etc. most starting at or just above minimum wage rate.  The hospitality industry is full or low wage, limited skill jobs. So is agriculture in rural areas. The problem is the message sent to kids?  Education is not rewarded, so why bother.

So what does this have to do with utilities?  Utilities are everywhere and inn every community. Education affects utilities because as technology grows, we need better job skills from workers.  Gone are the days of hiring people to dig ditches that may not need to read, write or do math.  We are computerizing everything.  As a result all of our jobs, regardless how much labor may be involved, need skills.  Utility field people are the face of the utility.  We need qualified, employees to can represent the utility well, not uneducated, ignorant people who can’t answer questions or who cannot communicate with the public about what they are doing.  The question is how to solve this problem especially in rural areas where education may not be valued. 

First, we need to get into the schools.  Not colleges, but middle schools.  That is where many students appear to be lost.  They get to be 16 and drop out.  Hanging out, not working, gangs, crime, drug cultures, etc all appear to be “easier” than going to school and then working to earn a living.  We need to create value in all of our jobs.  Certainly not all jobs need a college education, but  a high school diploma with basic abilities to read, write, do math and communicate to the public are needed to create value for us. We need to impress on rural communities and inner city kids that we provide desirable jobs and encourage them toward us.  That may mean internships, student efforts in schools, tours, and lots of interaction with teachers.  It takes time, but may be worth our while on many levels.  

Happy 91st Pop! It’s been 2.5 years since you were last with us, but it’s funny how many things popped (no pun intended) up today that connect to you. Clearly you are still watching what goes on. We had a family summer cottage located 8 miles east of Grayling Michigan. So today I came across an old book entitled the Old AuSable written in 1963 by Hazen Miller, a U of M doctor (you were a U of M aerospace engineer) who wrote about the area back in the day (1870s to 1920s), just before your father purchased property along the AuSable River. It mentions the great grandfather of my dad’s summer playmates, one of whom just died last summer - his obit came up in my email today. Reminded me of many places I went as a kid. Funny it also reminded me of some of the old “names” that are now being lost to time, but created what exists today. It also helped with some perspective on a proposal I have been working on regarding water supplies and quality. The grayling fish disappeared by 1912 as a result of hanged on water quality (warming and silt), human impacts of logging on the fish and the introduction of other species. My proposal looks at impacts of human activity on SE Florida, especially as it relates to sea level rise and the need to capture additional soil storage capacity through infiltration trenches. The water cannot be discharged to tide due to Human-induced nutrient and roadway pollutants of the potential exists to impact fish populations. So we are looking at moving the infiltrated water to water plants in the future. We can treat the water there, cost effectively while solving another problem – diminishing water supplies for urban populations. This would diminish our need to deal with desalination and the disposal of concentrate, another proposal. Funny how sometimes it all comes together….Good times back then and up there. Making progress today. Thanks and keep on watching out for us!!


I recent Wall Street Journal article outlined where growth is likely to be coming.  Of no surprise, Arizona, Las Vegas, Central Valley, San Antonio, Dallas, Houston, Denver, Albuquerque, Boise, Pensacola, Tallahassee, Raleigh, Atlanta, and the Washington DC area.  Only one of those areas is has water much water availability.  It means that all of these communities are in areas that are water limited.  We already know that Texas, Las Vegas and Arizona have lots of water problems.  Most of these areas have had issues in the past as well, and will have more in the future. 

Low growth areas:  Detroit, Cleveland, Chicago, Buffalo, Cincinnati, Omaha, and a variety of areas with plenty of water, but old infrastructure and limited funding.  So the big questions is how do we redirect development to areas with plenty of water as opposed to allowing development in areas where we know that there will be serious water supply consequences in the future?  It’s a leadership issue, but local officials and states are so in need to the growth we have discussed in prior blogs, that the long-term realities of water supply limits overrides the short term need to show growth in the communities to delay tax increases, water increases and the like.  But is delays the inevitable, with potentially serious future impacts.

 


In front of house

The doorbell rang and it was 1:30 am on a Saturday morning.  It was my neighbor telling me about a small problem on the street.  I looked out and the entire block was flooded.  Water was moving. It was dark, and while my street light was working, it shed little light in the blackness.  However I figured out the old AC pipeline in front of my house had sheared and the block’s leak was actually my problem.  We had no water.  Fortunately the water department was able to get the main repaired in a couple hours.

The next morning we were not as lucky.  Another break on the next street over had shut us down again.  AC water main, but this time under a tree.  They had to remove the tree before fixing the line.  We were out all day.  The water plant guys and the repair crew said that the lines were supposed to be replaced a couple years ago, but that the City had delayed the replacement for budget problems.
