FAILURE TO ACT: Economic Impact of Current Investment Trends in Water & Wastewater Infrastructure

Screen Shot 2018-10-07 at 7.14.56 PMEXECUTIVE SUMMARY Of all the infrastructure types, water is the most fundamental to life, and is irreplaceable for drinking, cooking, and bathing. Farms in many regions cannot grow crops without irrigation. Government offices, hospitals, restaurants, hotels, and other commercial establishments cannot operate without clean water. Moreover, many industries—food and chemical manufacturing and power plants, for example—could not operate without the clean water that is a component of finished products or that is used for industrial processes or cooling. Drinking-water systems collect source water from rivers and lakes, remove pollutants, and distribute safe water. Wastewater systems collect used water and sewage, remove contaminants, and discharge clean water back into the nation’s rivers and lakes for future use. Wet weather investments, such as sanitary sewer overflows, prevent various types of pollutants like sewage, heavy metals, or fertilizer from lawns from ever reaching the waterways.

However, the delivery of water in the United States is decentralized and strained. Nearly 170,000 public drinking-water systems are located across the U.S. Of these systems, 54,000 are community water systems that collectively serve more than 264 million people. The remaining 114,000 are non-community water systems, such as those for campgrounds and schools. Significantly, more than half of public drinkingwater systems serve fewer than 500 people.

As the U.S. population has increased, the percentage served by public water systems has also increased. Each year new water lines are constructed to connect more distant dwellers to centralized systems, continuing to add users to aging systems. Although new pipes are being added to expand service areas, drinking-water systems degrade over time, with the useful life of component parts ranging from 15 to 95 years.

Particularly in the country’s older cities, much of the drinking-water infrastructure is old and in need of replacement. Failures in drinking-water infrastructure can result in water disruptions, impediments to emergency response, and damage to other types of essential infrastructure. In extreme situations caused by failing infrastructure or drought, water shortages may result in unsanitary conditions, increasing the likelihood of public health issues.

The United States has far fewer public wastewater systems than drinking-water systems— approximately 14,780 wastewater treatment facilities and 19,739 wastewater pipe systems as of 2008.1 In 2002, 98 percent of publicly owned treatment systems were municipally owned.2 Although access to centralized treatment systems is widespread, the condition of many of these systems is also poor, with aging pipes and inadequate capacity leading to the discharge of an estimated 900 billion gallons of untreated sewage each year.3

The EPA estimated the cost of the capital investment that is required to maintain and upgrade drinking-water and wastewater treatment systems across the U.S. in 2010 as $91 billion. However, only $36 billion of this $91 billion needed was funded, leaving a capital funding gap of nearly $55 billion.

Water infrastructure in the United States is clearly aging, and investment is not able to keep up with the need. This study’s findings indicate that investment needs will continue to escalate. As shown in Table 1, if current trends persist, the investment required will amount to $126 billion by 2020, and the anticipated capital funding gap will be $84 billion. Moreover, by 2040, the needs Failure to Act: The Economic Impact of Current Investment Trends in Water and Wastewater Treatment Infrastructure 5 for capital investment will amount to $195 billion and the funding gap will have escalated to $144 billion, unless strategies to address the gap are implemented in the intervening years to alter these trends.

Effects on Expenses

Even with increased conservation and costeffective development of other efficiency methods, the growing gap between capital needs to maintain drinking-water and wastewater treatment infrastructure and investments to meet those needs will likely result in unreliable water service and inadequate wastewater treatment. Because capital spending has not been keeping pace with needs, the resulting gap will only widen through 2040. As a result, pipes will leak, the construction of the new facilities required to meet stringent environmental standards will be delayed, addressing the gap will become increasingly more expensive, and waters will be polluted. This analysis assumes that the mounting costs to businesses and households will take the form of:

★ Doing nothing and living with water shortages, and higher rates (rationing through price increases); or major outlays by businesses and households, including expenditures incurred by moving to where infrastructure is still reliable, purchasing and installing equipment to conserve water or recycle water, and increasing reliance on selfsupplied water and/or wastewater treatment (i.e., installing individual wells and septic waste systems when municipal facilities and services are not available options), and

★ Incurring increased medical costs to address increases in water-borne illnesses due to unreliable delivery and wastewater treatment services.

These responses to failing public infrastructure will vary by location, household characteristics, and size and type of business. Expenditures due to moving, or from installing and operating new capital equipment for “self-supply,” are estimated for households, commercial establishments, and manufacturers. These costs are estimated at $35,000 per household and $500,000 to $1 million for businesses, depending on size and water requirement, and are amortized over 20 years. Although these expenditures are based on the costs associated with self-supply, the costs are used to represent outlays by some households and businesses in response to unreliable water delivery and wastewater treatment services. This study does not assume that companies or households move outside of the multistate region where they are now located.

However, movement across regional boundaries and relocation of businesses outside of the U.S. is certainly a response that may be triggered by decreasing reliability of public water and sewer systems. Households and businesses that do not self-supply are assumed to absorb the higher costs that are a consequence of disruptions in water delivery and wastewater treatment due to worsening infrastructure. The assumption for this category is that these households and businesses will pay the $84 billion associated with the 2020 capital gap ($144 billion by 2040) in terms of higher rate costs over and above the baseline projected rates for water and wastewater treatment.

Water-borne illnesses will exact a price in additional household medical expenditures and labor productivity due to sick time used. The EPA and the Centers for Disease Control and Prevention have tracked the 30-year incidence of water-borne illnesses across the U.S., categorized the type of illnesses, and developed a monetary burden for those cases. That burden is distributed partially to households (29 percent), as out-of-pocket fees for doctor or emergency room visits, and other illness-related expenses leaving less for a household to spend on other purchases, and mainly to employers (71 percent), due to lost labor productivity resulting from absenteeism. The monetary burden from contamination affecting the public-provision systems over the historical interval was $255 million.

Overall Summary of Costs

The sum of estimated expenses to households and businesses due to unreliable water delivery and wastewater treatment is shown in Table 2. By 2020, the total costs to businesses due to unreliable infrastructure will be $147 billion while that number will be $59 billion for households. The total impact of increased costs and drop in income will reduce the standard of living for families by almost $900 per year by 2020.

Effects on the National Economy

By 2020, the predicted deficit for sustaining water delivery and wastewater treatment infrastructure will be $84 billion. This may lead to $206 billion in increased costs for businesses and households between now and 2020. In a worst case scenario, the U.S. will lose nearly 700,000 jobs by 2020. Unless the infrastructure deficit is addressed by 2040, 1.4 million jobs will be at risk in addition to what is otherwise anticipated for that year.

The impacts of these infrastructure-related job losses will be spread throughout the economy in low-wage, middle-wage and high-wage jobs. In 2020, almost 500,000 jobs will be threatened in sectors that have been traditional employers of people without extensive formal educations or of entry-level workers.4 Conversely, in generally accepted high-end sectors of the economy, 184,000 jobs will be at risk.5

The impacts on jobs are a result of costs to businesses and households managing unreliable water delivery and wastewater treatment services. As shown in Table 3, between now and 2020, the cumulative loss in business sales will be $734 billion and the cumulative loss to the nation’s economy will be $416 billion in GDP. Impacts are expected to continue to worsen. In the year 2040 alone, the impact will be $481 billion in lost business sales and $252 billion in lost GDP.6 Moreover, the situation is expected to worsen as the gap between needs and investment continues to grow over time. Average annual losses in GDP are estimated to be $42 billion from 2011 to 2020 and $185 million from 2021 to 2040.7

The Role of Sustainable Practices

In all likelihood, businesses and households will be forced to adjust to unreliable water delivery and wastewater treatment service by strengthening sustainable practices employed in production and daily water use. The solutions already being put forward and implemented in the United States and abroad include voluntary limitations or imposed regulations governing the demand for water, as well as technologies that recycle water for industrial and residential purposes (e.g., using recycled shower water for watering lawns). These types of policies have reduced the demand for water and wastewater, and, therefore have lessened the impacts on existing infrastructure.

Screen Shot 2018-10-07 at 7.18.33 PM.png

The most recent Clean Watersheds Needs Survey (EPA 2010) incorporates new technologies and approaches highlighted for wastewater and stormwater: advanced treatment, reclaimed wastewater, and green infrastructure. In contrast, the most recent Drinking Water Needs Survey (EPA 2009) does not include new technologies and approaches, such as separate potable and nonpotable water and increasing efficiencies.

American businesses and households have been using water more efficiently, and they can continue to improve their efficiency during the coming decades. As shown in Figure 1, though the U.S. population has continued to grow steadily since the mid-1970s, total water use has been level. Overall, U.S. per capita water use peaked in the mid-1970s, with current levels being the lowest since the 1950s. This trend is due to increases in the efficiency of industrial and agricultural water use and is reflected in an increase in the economic productivity of water. These trends in industrial water use can be explained by a number of factors. For example, several water-intensive industries, such as primary metal manufacturing and paper manufacturing, have declined in the U.S., thereby reducing water withdrawals. Other industries have faced more stringent water quality standards under the Clean Water Act, which may have led to the implementation of technologies or practices that save water.8

Nationally, water use in the home has remained stable since the 1980s. Efficiency and conservation efforts have reduced per capita household consumption in some states and regions. Domestic water use has become more efficient through the use of new technologies such as water-efficient toilets that use one-third of the water of older toilets. In addition, new technologies and approaches may reduce future water infrastructure needs. For example, many cities have recently adopted green infrastructure approaches to wet weather overflow management. Green roofs, grassy swales, and rain gardens, for example, are used to capture and reuse rain to mimic natural water systems. Such techniques often provide financial savings to communities.

Nevertheless, demand management and sustainable practices cannot solve the problem alone. These efforts are countered by increasing populations in hot and arid regions of the country—including the Southwest, Rocky Mountains, and Far West—where there is greater domestic demand for outdoor water use.9 In this study, a second scenario was run, which assumed that there would be a general adjustment by businesses and households as the capital gap worsened.

In this scenario, negative economic impacts mount for about 25 years—roughly 2011–35, though at a slower pace than the earlier scenario—and then abate as increasing numbers of households and businesses adjust to the reality of deficient infrastructure, including net losses of 538,000 jobs by 2020 and 615,000 jobs by 2040. In this scenario, job losses peak at 800,000 to 830,000 in the years 2030–32.

In addition, GDP would be expected to fall by $65 billion in 2020 and $115 billion in 2040. The lowest points in the decline in GDP would be in 2029–38, when losses would exceed $120 billion annually. After-tax personal income losses under this scenario are $87 billion in 2020 and $141 billion in 2040, which represents a rebound from $156 billion to $160 billion in annual losses in the years 2030–34.

The Objectives and Limits of This Study

The purpose of this study is limited to presenting the economic consequences of the continuing underinvestment in America’s water, wastewater, and wet weather management systems. It does not address the availability or shortages of water as a natural resource or the cost of developing and harnessing new water supplies. Joining water delivery and wastewater treatment infrastructure with the costs of developing new water supplies is an appropriate and important subject for a more extensive follow-up study. This report assumes that the current regulatory environment will remain in place and no changes to current regulations will occur. Finally, this work is not intended to propose or imply prescriptive policy changes. However, many organizations and interest groups, including ASCE, continue to engage with policy makers at all levels of government to seek solutions to the nation’s infrastructure problems.


Well-maintained public drinking water and wastewater infrastructure is critical for public health, strong businesses, and clean rivers and aquifers. Up to this moment American households and businesses have never had to contemplate how much they are willing to pay for water if it becomes hard to obtain.

This report documents that capital spending has not been keeping pace with needs for water infrastructure, and if these trends continue, the resulting gap will only widen through 2040. As a result, pipes will leak, new facilities required to meet stringent environmental goals will be delayed, O&M will become more expensive, and waters will be polluted.

There are multiple ways to partially offset these negative consequences. Possible preventive measures include spending more on existing technologies, investing to develop new technologies and then implementing them, and changing patterns in where and how we live. All these solutions involve costs. Separately or in combination, these solutions will require actions on national, regional, or private levels, and will not occur automatically.



Study Finds Microplastics In 93% Of Bottled Water

20180315_Plastic_WaterLowest and highest number of plastic particles found per liter of bottled water (location & brand)

The World Health Organization (WHO) has announced that it is launching a review of the potential risks of plastic particles in drinking water, after a study found tiny pieces of plastic in more than 90% of samples from the world’s most popular bottled water brands.

That analysis was conducted by the State University of New York in Fredonia as part of a project from the U.S.-based journalism organization Orb Media, and it involved 259 bottles of water from 11 brands across nine countries. They were bought in China, Brazil, India, Indonesia, Mexico, Lebanon, Kenya, Thailand and the U.S.

Of all the bottles tested, only 17 were found to be free of plastic. On average, each liter sold contained 325 pieces of microplastic, including polypropylene, nylon, and polyethylene terephthalate. In one case, a bottle of Nestlé Pure Life contained more tahn 10,000 pieces of microplastic. High levels were also found in bottles of Bisleri (5,230), Gerolsteiner (5,160) and Aqua (4,713).

According to WHO officials, there is no evidence that the consumption of microplastic fibers has an impact on human health, but it remains an emerging area of concern.

90% of Americans Receive Drinking Water from Public Systems – $1Trillion Needed to Fix

Screen Shot 2018-10-07 at 7.11.36 PMDrinking water is delivered via one million miles of pipes across the country. Many of those pipes were laid in the early to mid-20th century with a lifespan of 75 to 100 years. The quality of drinking water in the United States remains high, but legacy and emerging contaminants continue to require close attention. While water consumption is down, there are still an estimated 240,000 water main breaks per year in the United States, wasting over two trillion gallons of treated drinking water. According to the American Water Works Association, an estimated $1 trillion is necessary to maintain and expand service to meet demands over the next 25 years.



Florida high school students discover traces of a cancer-causing algae



Misspelled words, confused information. This article would be incredibly flattering if it were correct.  Let me, please, set the record straight:

(1) the hundreds of samples came from Joseph R. who was testing for NITRATES (fecal matter), COPPER (fecal matter from fertilizer), and IBUPROFEN (fecal matter from humans) in surface water grab samples. Of his samples 98% had nitrates, and of that 98%, approx. 50% came up with ibuprofen and copper. MEANING, human waste from septic is seeping from groundwater into the intercoastal and beaches. MEANING, a surface water grab sample would heavily dilute concentrations = there is a great deal of human waste and fertilizers in the water. THIS is what feeds the blue-green alga (microcystin) and the red tide (K. brevis). THIS is what tells us the sources for remediation.

(2) The microcystin was found, post plume, in the INTERCOASTAL, NOT the river near Sewell’s point. MEANING, the tides are pushing in and up into the intercoastal both K. brevis and microcystin. BIG DIFFERENCE than what she is reporting. This does NOT encourage my trust in their news “making”…

Bottled water from major brands like Aquafina, Nestle, and Dasani contains tiny plastic particles — here’s what that does to your body

  • Studies suggest disposable, plastic water bottles can harbor hundreds of tiny bits of plastic, and we’re drinking them down with bottled H2O.
  • Microplastics are all over the place: in our salt, contaminating our seas, and running out of our taps, too.
  • But there are even more of them lurking in bottled water, which is concerning.

You’re drinking plastic, I’m drinking plastic, we’re all drinking plastic. Bottled water drinkers may be drinking the most plastic of all.

A new study released by Orb Media estimates that on average, a liter of bottled water from big brands like Dasani, Aquafina, and Nestle, contains roughly 10.4 plastic particles.

The world drinks them in swiftly, consuming roughly a million plastic bottles a minute, as the Guardian estimates. And researchers think there are probably even more, much tinier plastic bits swimming in the bottles that are nearly untraceable.

In our modern, plastic-brimming world, these little plastic bits — many thinner than a human hair — are ubiquitous.We don’t know exactly what these plastic parts are doing to our bodies, but we’re drinking them in anyway. That’s an alarming prospect, because in the ocean, these little plastics are doing harmful things to fish. In some species, they’re even slowing down growth and reproduction.

While there isn’t clear evidence yet that the plastics in disposable water bottles can increase cancer risk, we know that bottles containing a chemical called BPA do. The endocrine-disrupting hard BPA plastics in certain re-useable water bottles can lead to higher instances of infertility, breast and prostate cancer, and early puberty. And a few studies suggest the softer kinds of disposable water bottles can have similar, endocrine-disrupting chemicals inside.

The World Health Organization says there’s no clear evidence yet that microplastics are bad for us. But there has also been very little study of microplastic drinking. WHO spokesman Tarik Jašarević told Business Insider there’s “very scarce available evidence” about what microplastics do inside our bodies, but the health organization wants to do more thorough research about the potential health risks of drinking little pieces of plastic.

Aquafina and Dasani both told Business Insider their bottled waters are tested to strict standards and pass through high-quality filtration systems. Nestle said the company hasn’t found microplastics in its water bottles beyond a “trace level,” disputing the new study numbers. Evian did not immediately respond to a request for comment.

The particles aren’t just in our bottles. They come out of our taps, too (though in smaller amounts than plastic bottle concentrations, according to the most recent study). The tiny plastics are alsoswimming in the seas and disrupting the way fish eat. In Turkey, microplastics are even slipping into the salt markets. Even water bottler Dasani wrote in its statement: “It’s clear the world has a problem with plastic waste.”
