Tag Archives: water and sewer


Earlier this year the Journal for AWWA had several articles about water use and infrastructure needs.  One of the major concerns that has arisen in older communities, especially in the Rust Belt and the West is that demands per person have decreased.  There are a number of reasons for this –the 1992 Energy Policy Act changes to plumbing codes that implemented low flush fixtures, the realization in the west that water supplies are finite and conservation is cheaper than new supplies, a decline in population, deindustrialization, and climate induced needs.  But all add up to the result that total water use has not really changed over the past 30 years and in many locales, water sales may have decreased.  Water utilities rely on water sales for revenues so any decrease in sales must be met with an increase in cost.  Price elasticity suggests the increase will be met with another decrease in sales, etc.  It is a difficult circle to deal with.  So less water, whether through deliberate water conservation or other means, creates a water revenue dilemma for utilities.  A concern about conserving to much and eliminating slack in the system also results.

Less water means less money for infrastructure.  Communities do not see a need for new infrastructure because there are fewer new people to serve.  Replacing old infrastructure has always been a more difficult sell because “I already have service, why should I be paying for more service” is a common cry, unless you are in my neighborhood where the water pipes keep breaking and we are begging the City to install new lines (they are on my street J)  Educating customers about the water (and sewer) system are needed to help resident understand the impacts, and risk they face as infrastructure ages.  They also want to understand that the solutions are “permanent” meaning that in 5 or 10 years we won’t be back to do more work.  Elected officials and projected elected officials (the tough one) should be engaged in this discussion because they should all be on the same page in selling the ideas to the public.  And the needs are big.  We are looking at $1 trillion just for water line replacement by 2050 and that is probably a low number(2010 dollars).  The biggest needs are in the south where infrastructure will start hitting its expected life.  The south want west will also be looking for about $700 billion in growth needs as well.  All this will cause a need for higher rates, especially with ¼ less low interest SRF funds avaialalbe this year from Congress.


Public water and sewer systems have the responsibility to protect the health, safety and welfare of the public they serve, just as engineers do.  This is includes not just complying with regulatory mandates (they are minimum standards), but enacting such precautions as are needed to address things not included in the regs.  Unfortunately we continue to pay too much attention on regulatory compliance and evaluate the condition of the system using unaccounted for water losses or leaks fixed in the system as a measure of condition.  That may be an incorrect assumption.  The problem is that unless we understand how the system operates, including how it deteriorates with time, the data from the past may well be at odds with the reality of the future.  For example, that leak in your roof can be a simple irritation for a long time if you ignore it.  But ignoring it creates considerable potential for damage, including roof failure if too much of the structure underneath is damaged.  With a water system, pipes will provide good service for many years will minimal indication of deterioration.  Then things will happen, but there is little data to indicate a pattern.  But like your roof leak, the damage has been done and the leaks are an indication of the potential for failure.  Bacteria, color, pressure problems and flow volumes are all indicators of potential problems, but long-term tracking is needed to determine develop statistical tools that can help with identifying end of life events.  Basic tools like graphs will not help here.

Construction to repair and replace local water, sewer and stormwater infrastructure is expected to reach $3.2 and $4.8 billion respectively for water and sanitary sewer. The federal SRF programs are only $1.7 Billion in SRF loans, 24% below 2012 and well below the levels identified by the federal government to sustain infrastructure condition.  The only reason for the decrease seems to be a demand by Congress to reduce budgets, especially EPA’s budget where this money resides.  But the 2008 recession and its lingering effects to date have deferred a significant amount of infrastructure investments, and the forecast does not rectify the past deficits, and likely does not address the current needs either.  Few water and sewer systems are flush with funds to update infrastructure and borrowing has become a difficult sell for many public officials.  Lake Worth, FL just had a $60 million bond issue for infrastructure redevelopment defeated by voters two weeks ago.  The officials know they need this infrastructure, but the public is unconvinced because few serious problems have occurred.  We have to get the public past this view so we can improve reliability and public safety.  Those are the arguments we need to demonstrate.  The question is how.

 


So what does this mean for water and sewer utilities. First, we’d love to stay out of the fray. Water and sewer utilities recognize that they are the “peak” power supply for electric utilities. The means to expand power supplies is made difficult by the rules for capital recovery for power utilities that penalizes peak and redundant power supply construction. It must be used and useful to qualify for a return. Hence NextEra builds inexpensive, small increment renewable wind systems to be made whole and encourages residents to reduce demands so they do not need to build more large scale capacity. That works as long as access to renewables or increases in efficiency are available. The use of federal subsidies encourages the used of new technology but without the subsidies, expect the construction to slow.

The European Union is looking to phase out renewable power subsidies by 2017, which may have fairly significant consequences for the European renewable market. The Koch brothers and the Tea Party operatives they fund through many organizations like the Institute for Energy Research, Americans for Prosperity and the Heritage Foundation, are fighting federal tax credits for wind, while backing tax credits for oil and gas. Why do the Koch brothers keep showing up? Because as we noted in a prior blog – they stand to lose profits if the US depends less on oil and gas IT si a problem with big money interests using that money for self preservation as opposed to progression of technology and ideas.

Think what would have happened 100 years ago if big money was allowed to control progress. And I have just the perfect scenario pitting two sides of my family. My mother’s great uncle made Concord coaches. As long as horse drawn carriages and coaches were the primary transportation options, they made money. OF course many cities and towns found that they spend much of their tax money cleaning up after the horses, one of the all-time yuckiest jobs. Tons of horse poop was cleaned up nightly on the streets on many cities. Images are available on line. Of course there was also the stench, disease, vectors, etc associated with all that poop.

Then came Henry Ford. My Dad’s side of the family were Detroiters. They got jobs in the Ford factories, and made money from services to autoworkers as well. The cities loved having cars – less poop. In fact Henry’s cars worked so well, that very quickly cities didn’t have to pick up poop. And the stench and disease decreased. Of course back then, my mothers’ family did not have the same means to buy influence to prevent Henry Ford from producing cars. My uncle went broke, but America and my father’s family in Detroit, benefitted greatly as a result of the new technology. I think we all benefitted from the automobile. Thankfully the coachmakers didn’t have money.

Using politics and influence to resist new technology seems unAmerican. Using subsidies to encourage is seems far more beneficial to society as long as those subsidies actually benefit society. Subsidies have long been a means for governments to alter consumer and corporate behavior and encourage new technologies. Subsidies for recycling steel, aluminum, glass, paper and other materials remained in place until the technology was cost effective to compete with new materials. Now recovered steel is cheaper than new steel materials. The subsidies had their effect. The same is true with aluminum and glass. Subsidies in the form of grants encouraged water and sewer utilities to upgrade treatment and install pipes to serve new customers. Now those are low interest loans because most of the cost effective connections have been made. It benefitted society.

Subsides have been used for years in the US and Europe to encourage renewable power use. The result is a reduction in renewable costs as more people invested in the technology. Greater supply means lower costs (economy of scale, and, theory of economic supply and demand), and subsides are designed to reduce purchase prices sooner than the market might otherwise. Otherwise most of these industries never get off the ground because they cannot get to cost effective production levels. Stay tuned.


In the last blog we discussed 10 planning steps for sea level rises.  When planning 50-100 years other factors can come into play as well.  As a result, to allow flexibility in the analysis due to the range of increases within the different time periods, an approach that uses incremental increases of 1, 2, and 3 feet of SLR is suggested.  Hence infrastructure is built to meet milestones, not arbitrary dates lessening the potential for stranded assets.. The increments can work as threshold values in planning considerations in terms of allowing planners the ability to know ahead of time where the next set of vulnerable areas will be to allow a for proactive response approach that can be matched to the observed future sea levels.

But prior to developing infrastructure plans, the local community needs to define an acceptable level of service (LOS) for the community. A level service would indicate how often it is acceptable for flooding to occur in a community on an annual basis.  1% is 4 days per years and for a place like Miami Beach, this is nearly 2 ft NAVD88, well above the mean high tide.  The failure to establish an acceptable LOS is often the cause of failure or loss of confidence in a plan at a later point in time.  The effects of SLR of the level of service should be used to update the mapping to demonstrate how the level of service changes, so that a long-term LOS can be defined and used for near-term planning.

With the LOS known, the vulnerability assessment is developed using a GIS based map of topography and the groundwater levels associated with wet and dry season water levels.  LiDAR is a useful tool that may be available at very high resolution in coastal areas.  Topographic maps must be “ground-truthed” by tying it to local benchmarks and transportation plans.  USGS groundwater and NOAA tidal data from local monitoring stations to correlate with the groundwater information. Based on the results of these efforts, the GIS-based mapping will provide areas of likely flooding.

GIS map should be updated with layers of information for water mains, sewer mains, canals, catch basins, weirs and stormwater facilities.  Updating with critical infrastructure will provide a view of vulnerability of critical infrastructure that will be funded by the public sector. Ultimately policy makers will need more information to prioritize the needed improvements.  For example, a major goal may be to reduce Economic Vulnerability.  This means identifying where economic activity occurs and potential jobs.  At-risk populations, valuable property (tax base) and emergency response may be drivers, which means data from other sources should be added.

The next step is to analyze vulnerability spatially, by overlaying development priorities with expected climate change on GIS maps to identify hotspots where adaptation activities should be focused. This effort includes identification of the critical data gaps which, when filled, will enable more precise identification of at risk infrastructure and predictions of impacts on physical infrastructure and on communities. The final deliverable will include descriptions of the recommended concepts including schematics, cost estimates, and implementation plan.

So why go through all this.  Let’s go back to the beginning.  It has to do with community confidence in its leaders.  Resident look at whether their property will be protected.  Businesses look at long-term viability when making decisions about relocating enterprises.  The insurance industry, which has traditionally been focused on a one year vision of risk, is beginning to discuss long-term risks and not insuring property rebuild is risk-prone areas.  That will affect how bankers look at lending practices, which likely will decrease property values.  Hence it is in the community’s interests to develop a planning framework to adapt to sea level rise and protect vulnerable infrastructure through a long-term plan.  Plan or….


The rainy season has sort-of started in south Florida and with it comes flooding and discussions of the falls end of season and concurrent high, high tides for the year, flooding and the impact of sea level rise on low-lying areas.  Much focus has been spent on the causes of sea level rise and the potential flooding caused by same.  However the flooding can be used as a surrogate to impacts to the social and economic base of the community.  By performing vulnerability assessments, coastal areas can begin planning for the impacts of climate change in order to safeguard their community’s social, cultural, environmental and economic resources. Policies need to focus on both mitigation and adaptation strategies, essentially, the causes and effects of climate change. Policy formulation should be based on sound science, realizing that policy decisions will be made and administered at the local level to better engage the community and formulate local decisions.

Making long-term decisions will be important.  Businesses look at long-term viability when making decisions about relocating enterprises.  The insurance industry, which has traditionally been focused on a one year vision of risk, is beginning to discuss long-term risks and not insuring property rebuild is risk-prone areas.  That will affect how bankers look at lending practices, which likely will decrease property values.  Hence it is in the community’s interests to develop a planning framework to adapt to sea level rise and protect vulnerable infrastructure through a long-term plan.

While uncertainties in the scale, timing and location of climate change impacts can make decision-making difficult, response strategies can be effective if planning is initiated early on. Because vulnerability can never be estimated with great accuracy due to uncertainty in the rate of warming, deglaciation and other factors, the conventional anticipation approach should be replaced or supplemented with one that recognizes the importance of building resiliency.  The objectives of the research were to develop a method for planning for sea level rise, and providing a means to prioritize improvements at the appropriate time.  In addition the goals were to provide guidance in developing a means to prioritize infrastructure to maximize benefit to the community by prioritizing economic and social impacts.

Adaptation planning must merge scientific understanding with political and intuitional capacity on an appropriate scale and horizon.  According to Mukheibir and Ziervogel (2007), there are 10 steps to consider when creating an adaptation strategy on the municipal level.  To summarize, these are as follows:

  1. Assess current climate trends and future projections for the region (defining the science).
  2. Undertake a preliminary vulnerability assessment of the community and communicate results through vulnerability maps (using GIS and other tools).
  3. Analyze vulnerability spatially, by overlaying development priorities with expected climate change on GIS maps to identify hotspots where adaptation activities should be focused.
  4. Survey current strategic plans and development priorities to reduce redundancy and understand institutional capacity.
  5. Develop an adaptation strategy that focuses on highly vulnerable areas. Make sure the strategy offers a range of adaptation actions that are appropriate to the local context.
  6. Prioritize adaptation actions using tools such as multi-criteria analysis (MCA), cost-benefit analysis (CBA) and/or social accounting matrices (SAM).
  7. Develop a document which covers the scope, design and budget of such actions (what they call a Municipal Adaptation Plan (MAP)).
  8. Engage stakeholders and decision-makers to build political support. Implement the interventions prioritized in the MAP.
  9. Monitor and evaluate the interventions on an ongoing basis.
  10. Regularly review and modify the plans at predefined intervals.

 

The strengths of this framework are the initial focus on location-specific science, the use of both economic and social evaluation criteria, and the notion that the plan is not a fixed document, but rather a process that evolves in harmony with a changing environment.  The final two steps occur at regular intervals by the community with associated adjustments made.  The next question is how to develop the data and priorities.


In the last blog I commented on the Donald Sterling, Thomas Sowell and Clive Bundy comments the week before. I wonder if letting the hate out just a way to keep us from looking at the bigger picture from a political (and maybe business) perspective? And should utilities we concerned? The answers may be yes, and yes an dhere is why. An August 2012 Pew Research Center report noted that only half of American households are middle-income, down from 61 percent in the 1970s. The shift was downward, not upward as the very rich (0.1%) control 58% of the wealth in the US. In addition, median middle-class income decreased by 5 percent in the last decade, while total wealth dropped 28 percent. The need for social programs, despite cutbacks and revisions to the welfare programs in the Clinton era, have increased – since 2000 Medicaid has increased from 34 million people to 54 million in 2011 and the Supplemental Nutrition Assistance Program (SNAP, or food stamps) from 17 million to 45 million in 2011. Keep in mind that income drives qualification for these services so it means that incomes are down for millions in America. The increase in people needing help is no surprise since there is an ongoing increase in the number of lower-wage service jobs like food preparation, retail and service industry, but the number of middle-class occupations, like teaching and construction, have declined. Since 2010, the State of Florida has added 400,000 jobs, impressive except that the vast majority are service and retail jobs that pay just above minimum wage. The job growth in low wage jobs does not replace the loss of middle income jobs which is why 47% of households did not earn enough to pay income tax in 2103. It is not because they don’t want to, it’s because they don’t get paid enough. And we have tens of millions of these low wage jobs that don’t pay enough for the recipients to pay taxes. Just the opposite of what some of the political discussion would have you believe.

The loss of wages is felt locally more than nationally. It means that local officials hear about costs more because water, sewer, power, etc competes for an ever larger portion of the shrinking paycheck. So we see more attention paid to affordability indexes, the ability to pay. The concept of affordability is to take your annual water and sewer bill and divide it by the average or median local income. The goal is water plus wastewater is under 3.5% of the median income. Keeping the percent low is great and easy when people are making more money, but creates a lot of difficulty when the incomes are static or dropping. An our costs are rising due to the increasing need to maintain and upgrade infrastructure that has been neglected since 1980 (the annual investment is under 1.4% for most of the US infrastructure for the last 30 years. We need to invest above 2.3% to keep up according to GAO).

When income drop, costs become more important, and local water and sewer costs are often easier targets to limit than groceries, rent, power, telephone, cable or other services that are not subject to local official votes. So it is in all of our interests to work with local officials, colleges, vocational schools, public schools et al. to attract or build a economy that features higher income jobs, to get everyone employed, and to provide training, infrastructure, outreach, health care and other help to establish a competent, highly skilled workforce in a community. That means that utilities must support the local efforts to effect social change in the community, to help meet the needs of residents not just with water, but with respect to the local economy as well. Does that mean we are actually agents for social change?


Good Day!  There are over 350 people that receive this blog via WordPress, Linked and Facebook.  Thank you.  .

So I want to let you know about a project I am working on to develop some measures to identify leadership perceptions in the industry.  So we have created an online survey that I would like to have you participate in.  It should take no more than 10 minutes of your time, but will help us formulate a larger survey of the industry.  I would love to get 100 responses.  I will report the results.  Your help is appreciated.

I had to share this, from a nonscientific survey of people adamantly opposed to any consideration of changes to our climate:

1. I can’t do anything about it so I don’t care about it
2. People can’t alter what is happening with the earth because it is too big
3. It’s natural, so we can’t do anything about it
4. It’s not an issue now, so it’s somebody else’s future problem
5. The science is inconclusive so why do anything yet. Let’s see what happens
6. Trying to address it will cut jobs
7. We won’t be competitive (i.e our profits will drop)
8. It requires changing our business model (energy)
9. If we talk about it no one will develop in our community
10. Costs too much

I had to post this as many of you will have comments. But before you do, these about this a minute……

The first five are based on no facts, but a desire to ignore the issue entirely. The second five are more poignant because aren’t these pretty much the same arguments to deny the need to correct water pollution concerns in the 1930s? Or 1950s? Or even 1970s? Or even today with hog farms, frack water, acid mine waste, coal dust slurries, etc.? Or actually pretty much every regulation? I seem to recall Tom Delay making this argument when he was in Congress before he was indicted.

Now think about the Clean Water Act, Clean Air Act, Safe Drinking Water Act, and others. These regulations are designed to correct ills of the past that were simply ignored due to the first five arguments above, ignoring the fact that prevention is always less costly than cleanup afterward. To we pass regulations to clean up problems and protect the public health going forward. Otherwise why have a regulation?

So let’s talk about that jobs impact. The reason is that after the passage of these regulations, didn’t the number of professional jobs (like civil and environmental engineers, environmental and other scientists – STEM jobs) increase? Isn’t increasing STEM jobs a priority? So won’t dealing with climate issue perhaps create a similar increase in STEM jobs? Yes, costs for water increased and the cost for the effects of climate changes will cost money, but don’t these challenges create opportunities? Isn’t this akin to dealing with problems with development from the past? Just asking…..


Let’s start with the basic premise of this conversation – fracking is here to stay!  It doesn’t matter how many petitions you get in the mail, fracking is going to continue because the potential for gas production from fracking and the potential to fundamentally change our energy future, near or long-term, far outweighs the risk or economic and security disruptions from abandoning fracking efforts.  It looks like there is a lot of trapped gas, even if the well exponentially decay production in the first three years, although many well can be recovered by refracking.  It is an issue that residents and utilities need to accept.  The question is really how to assess the risks to water supplies from fracking and what is what can we do about it?

There are a number of immediate regulatory issues that should be pursued, none of which Vikram Rao (2010) suggests are truly deal killers.  They start with the disclosure of the fracking fluids, which for most legitimate companies that are fracking are relatively benign (and do not include diesel fuel).  Baseline and ongoing monitoring of formations above the extraction zones, and especially in water production zones is needed.  Research on water quality treatment solutions is needed because t may be impossible to completely eliminate escaping gas is needed.  Requirements to improve and verify well construction and cementing of formation is needed in all states (they are not now) and recycling frack water and brine should be pursued to avoid impacts on streams and wastewater plants, which limits the loss of water due to fracking operation and the potential for contamination of surface water bodies.  It will be important to push for these types of regulations in states like Ohio and West Virginia that need jobs and are likely places for fracking to occur, but they are also likely places where there will be political pushback that is afraid of discouraging job investments, but in reality this is unfounded.  The gas is there, so the fracking will follow. The question is will the states implement needed regulations to protect the public.

More interesting will be the ancillary issues associated with gas and wet gas.  A lot of by products come from wet gas, like polyethylene which can be used as stock for a host of plastics.  “Crakers” are chemical processing plants that are needed to separate the methane and other products.  Where will those facilities be located, is an issue.  Right now they are on the Gulf coast, which does not help the Midwest.  Do we really need to ship the gas to Louisiana for processing or do we locate facilities where the gas and byproducts are needed (in the Midwest)?  The Midwest is a prime candidate for cracker location, which will create both jobs as well as potential exports.  Also stripping the gas impurities like ethane, DEM and others needs to occur.

So what do utilities need to look at the potential impacts on their water supplies and monitor.  If the states will not make the fracking industry do it, we need to.  Finding a problem from fracking after the fact is not helpful.  We need to look at potential competition for water supplies, which is in part why recycling frack water brine is needed.  Eliminating highly salty brine from going to a treatment plant or a water supply are imperatives.  Sharing solutions to help treat some of these wastes may be useful – something we can help the industry with is treating water.

We also need to look at the processing plants.  We need to be looking at the impact of these facilities in light of water and sewer demands (and limitations). Wet gas facilities will require water as will plastics and chemical plants. Historically a lot of these facilities were in the Midwest and the research and skill sets may still be present.  How can these industries can be merged into current water/sewer scenarios without adverse impacts.  Communities will compete for these facilities, but good decisions may dictate that vying is not the best way to locate a plant. 

But there is another impact to utilities and that affects green technologies. The cost of gas is low and looks like it will remain low in the near future.  Low gas prices mean that renewable solutions like solar and wind will be less attractive, especially if federal subsidies disappear.  Wind is the largest addition to the power generation profile in the last 5 years, while many oil facilities changed to gas.  Cheap gas may frustrate efforts to create distributed power options at water and wastewater treatment plants throughout the country which can directly benefit utilities, not just where fracking occurs. So we need to be cognizant of these cost issues as well.  And you thought the fracking discussion might not affect you….

 


So Detroit defaulted on it’s debt obligations.  Do does that impact you?  Well, that depends on whether you are a utility looking revenue bonds, a city looking for general fund bonds or some combination.  The issue in Detroit with debt is that they pledged the full faith and credit of their taxing authority to repay the debt.  Their taxing ability was insufficient to accomplish this goal, which means that there could now be distrust in that promise for other cities.  So if you are a city and you are making this pledge, Detroit could impact you, or at least create more review on your balance sheets.  If you are a utility that is pledging revenues that have no limitations on amount, the concern is likely less.  Of course in either cases, the question is what the rest of your balance sheet looks like.  If you have no reserves, do not charge the full cost for service, have a heavy debt load, have high rates already, or send a lot of funds to the general fund, that could be a problem.  If you have avoided these pitfalls, the bond market will see much less of an issue. 

Keep in mind that Detroit is not the only default – another big one is the Birmingham and several other create questions about general fund uses of funds, which makes it of greater importance to keep our financial house in order.  IN part this can be done by creating the appropriate enterprise funds and remove those services from the general property tax fund.  That permits local focus on the true cost of general taxing users and creates a delineation between general fund and enterprise costs.  That can help elected officials focus on the true general fund issues:  police, fire, EMS, administration without hiding those costs with subsidies from other funds.
