WATER: Self-healing systems

Self-healing water systems: rebuilding water. Image: water pipes, wikimedia commona.

Houston is rebuilding. A severe winter storm knocked out power, in February, leaving families and businesses huddled for elusive warmth. The Electric Reliability Council of Texas (ERCOT), supplier to 26 million people, proved not as reliable as its name. Collateral damage from the power outage: water problems. In the cold snap, water pipes cracked, causing water contamination and outages. Houston’s mayor admitted pipes were not insulated, also the case with power plants: disaster was foreseeable: “Our system in Texas is designed primarily for the summer heat, and not necessarily for a winter event. The reality is climate change is real, it is real, and these major storms can happen at any time.” (Turner 2021) Houston will have to rebuild its water system. United States’ declaration of disaster released federal funds. Rebuilding offers a chance not just to restore but to rethink. Could new technologies for self-healing systems offer options?

“Platelets.” Tieroardi 2005. wikimedia.

Self-healing pipes are inspired by human biology. When we experience a cut on the body’s skin, blood comes to the surface and then clots. It’s the work of platelets. That is what inspired engineer Ian McEwan of the University of Aberdeen, and now Scotland’s Brinker Technology to develop “artificial platelets” made from elastomeric material that can be injected into pipelines. When a leak occurs, the pressure change conveys the platelets to the leak, and they clog it. developed for pipelines carrying fuel and tested by British Petroleum and Shell, be adapted for municipal water systems? The method is currently being adapted to use in water pipes in the United Kingdom (UK) where 3,600 million liters of water leak out of pipes every day, causing water companies to repair by digging and replacing water pipes.

The Alaska Pipeline, completed in 1977, carries a different liquid; pipes are half buried underground and half above on elevated supports: a design innovation due to permafrost. Through the pipes are “smart pigs,”a playful name for serious devices housed in pipe interiors. If corrosion or leaks occur, smart pigs send a signal warning of disaster before it happens.

America is rebuilding. The United States has over a million miles of water supply mains – equal to 26 miles of water mains for every mile in the US federal highway system. It’s an old system: US pipes leak a full day’s water for every seven days, losing one of every seven gallons of drinking water. (Fishman 2014) Worldwide, 600 million people lack access to safe drinking water sources and systems. United Nations’ Sustainable Development Goal on water and sanitation urges safe access for all by 2030. As we address water access for all, installing new plumbing for some areas and rebuilding older systems in others, can we utilize smarter, self-diagnosing, self-healing water delivery systems?

WATER: World Water Day 2021

“Water Drop” by José Manuel Suárez, photographer, 2008. Image: wikimedia.

World Water Day, begun in 1993, calls us to honor and preserve the world’s freshwater supply. Water, in the form of drinking water and safe sanitation, is the #6 Sustainable Development Goal of the United Nations.  Environmental historians observe that human history can be traced by innovations in water systems. Aqueducts built by the Romans brought fresh spring water to a growing city when the Tiber river became threatened. In England, the New River was one of the world’s first built watercourses, bringing potable water to the burgeoning city of London. The Colorado River Compact defined the rights and use of water for the American states of the Upper Basin (Wyoming, Colorado, Utah, New Mexico) and Lower Basin (California, Arizona, Nevada); sovereign peoples of the Navajo, Havasupai, Walapai, and several others; and México.  Rights of the Whanganui River of New Zealand established legal personhood in 2017, confirming a growing awareness of the rights of nature. Today’s World Water Day 2021 is dedicated to our personal use of water. While 71% of the world has access to safe drinking water, only 45% have use of safe sanitation. To access the country data where you live, the United Nations invites you to explore the world water database here. To tell your own story about how you experience water, record your views here.

WATER: How much do you use?

How much water do you use? Image: “Blue question mark,” wikimedia commons.

Only 1% of water on Earth is drinkable (actually, it’s 2.5% but only 1% is readily accessible). The rest of the water on the planet rests in the sea, but it is salty and therefore requires desalination to use for drinking or agriculture.

New River, a fresh water supply and a fresh idea. Image: wikimedia.

Ever since the most ancient times, humans have invented ways to find, distribute, use, and power with water. From the Roman Aqueducts and the New River of England that brought fresh water to the growing cities of Rome and London, respectively, to the water use agreements of the Colorado River of the USA and Snowy Mountains Hydroelectric of Australia, the story of civilization is the story of water.

With populations growing and climate changing, water will become more scarce and more important for uses for drinking, agriculture, industry, and energy. While macro systems that deliver water to our taps are large in scale, each of us can do something to protect and conserve water.

WATER: How an idea for Mt. Everest could help 4 billion people

Mt. Everest: could an idea conceived on the summit improve the health of 4 billion people? Image: wikimedia.

Mt. Everest – a mountain so legendary that everyone wants to climb it. But mountaineers bring more than gear: they leave  28,000 pounds of human waste. Some is dumped in open pits, threatening water supply safety. That’s when Zuraina Zaharin, Everest climber and environmentalist, came up with an innovative idea. Partnering with Imad Agi, inventor of a waterless sanitation system using microbes to turn human waste into fertilizer so safe it can be used as fertilizer in organic farming, the duo launched EcoLoo. The system could be a solution for the 4 billion people worldwide who do not have in-house sanitation. And as water grows scarce in climate change, cutting consumption (we use 141 billion liters of fresh water daily just to flush toilets), EcoLoo could provide an alternative. Bill Gates sponsors a prize to reinvent the toilet, saving 432,000 lives lost each year to disease caused by inadequate sanitation. Water and sanitation have been linked to many advances in civilization, from the Roman Aqueducts to the New River. EcoLoo is now installing systems in remote locations like mountain environments, island vacation retreats; there are several at UNESCO World Heritage site Petra, and the company is planning to make units available for disaster response.

CITIES: Dangers in Deltas

New Orleans, Louisiana, USA. “KatrinaNewOrleansFlooded” by Kyle Niemi, U.S. Coast Guard, 29 August 2005. Image: wikimedia commons.

New Orleans, Louisiana, USA: it’s an unprecedented situation. New Orleans, a city on the Mississippi River Delta, is under threat. The river, normally about 7 feet high in the summertime, sits presently at 16 feet, the result of spring flooding along the waterway. Add to that a virulent storm barreling towards the city, driving a surge of 2 to 3 feet. If so, the river may crest at 17 feet. On land, there may be as much as 10-15 inches of rain from the storm, a dangerous followup to the 9 inch downpour that inundated the area the same week. Storm storage, high rivers, and rain – it’s a deadly combination. Delta cities, like New Orleans, may be in peril with climate change.

Cities, throughout history, have been built on coasts, offering access to trade through ports and waterways.  Singapore may be the quintessential city upon the waters, developed as one of the first Specialized Economic Zones. New York (and Brooklyn) became leading business centers when their place on the Atlantic Ocean became linked to inland towns, the the Great Lakes, through the Erie Canal. But now, rising seas, threaten coastal cities. In 2019, the Northeast Atlantic will experience a 140% increase in coastal flooding, compared with two decades ago. Worse still, the Southeast will suffer a 190% flood increase, according to a report by the National Oceanic and Atmospheric Administration (NOAA). And that’s just the USA.

Worldwide, cities are sinking and seas are rising; Jakarta, Indonesia may suffer some of the the worst effects of climate change; Indonesia’s capital might need to relocate. According to the World Economic Forum Global Risk Report 2019, 90% of all coastal areas in the world will be affected by climate change; some cities will combat sea rise 1/3rd above mean level. The bigger the cities (more heavy buildings), deeper sinking.

Delta cities, like New Orleans, are in danger; the list includes:

DELTA CITES ENDANGERED BY SEA RISE:

Dhaka

Guangzhou

Ho Chi Minh City

Hong Kong

Manila

Melbourne

Miami

New Orleans

New York

Rotterdam

Tokyo

Venice.

Source: Muggah, 2019. World Economic Forum 2019 states “Even if we keep global temperatures from rising more than 2 degrees centigrade by 2050, at least 570 cities will be damaged.” That means people, drinking water and sanitation, mass transit, power, roads, homes, businesses, hospitals, schools.

Dhaka, Bangladesh, a Delta City. Image: wikimedia.

It’s a sad business but a big one: coastal flooding could threaten 2 million homes in the United States, worth $882 billion. Worldwide, rebuilding or relocating coastal cities will take cause spending of $100, 000 Billion – per year. Is there any hope? Some historians observe that change and innovation  often are the result of crisis, citing examples as diverse as the Roman Aqueducts in response to a water crisis when the Tiber became not only polluted but endangered by terrorism (a threat of an enemy poisoning of the city’s water supply) to the intense research and development of the Manhattan Project resulting in the harnessing of Atomic Energy. Today, we face a similarly serious threat: will innovation save the day, or the century?

Rising seas, increasingly intense storms and hurricanes, are among forces eroding coastal cities, like New Orleans (or Jakarta). Saving sinking cities will demand significant innovations in urban harbors and cityscapes; cities with canals may lead the way to a better future. According to Henk Ovink, Special Envoy for International Water Affairs for the Netherlands and team leader of Rebuild by Design, “Worldwide, water is the connecting issue, the number one global risk and the opportunity for comprehensive cultural change.”

WATER: antibiotics on tap

Pills of antibiotic cefalexin. Photographer: Sage Ross, 2014. Image: wikimedia commons.

Feeling sick? It may the drugs you just took when you drank a sip of coffee or a glass of water. Affecting not just humans but aquatic life, medications are entering the water as fast as plastic – they’re just harder to see.

Antibiotics have been found in 65% of over 70 world waterways tested. For example, a site in Bangladesh showed Metronidazole present at levels 300 times the safe limits (20,000 to 32,000 nanogram per liter (ng/l) guidelines set by AMR Industry Alliance). The most frequent contaminant? trimethoprim found at 301 of 711 river testing sites. Most prevalent antibiotic found at dangerous levels: Ciprofloxacin, in 51 of the 72 countries tested.

Chao Phraya River Drainage Basin. Image: wikimedia.

Rivers all over the world show similar results: Chao Phraya, Danube, Seine, Thames.  Some areas of the world suffer infected water more: Bangladesh, Ghana, Kenya, Nigeria, and Pakistan ranked highest of sites monitored. In general, Asia and Africa frequently exceeded safety limits for antibiotics but problems were also found in Europe, North and South America. In other words, it’s global.

Of course, antibiotics save lives. But that’s just the problem: growing global resistance to antibiotics, anti fungals, antivirals caused 700,000 deaths yearly due to drug-resistant diseases, among them tuberculosis. The United Nations’ Interagency Coordination Group on Antimicrobial Resistance predicts that by 2030, over one million people will die every year due drug-resistant diseases.

PROBLEMS: Individuals are in no small part responsible: a study in California revealed half of all medications are discarded, often into the water supply. Another problem: even if we don’t intend to, individuals deposit drugs into the water supply.  People take a lot of drugs, both prescription and over-the-counter; our bodies metabolize only a percentage of the intake, excreting the rest into wastewater systems. And then there are the larger systemic depositors: hospitals try to return unused drugs to manufacturers obtaining a credit or at least assured safe disposal, but care and nursing facilities may not have such arrangements. Certainly drug manufacturers generate highly concentrated waste; downstream of a New York State pharmaceutical manufacturing plant, antibiotic concentrations showed levels 1,000 times higher than normal. And then there’s agriculture: poultry and livestock farming are responsible for two trillion pounds of animal waste filled with the hormones and antibiotics fed to the animals to optimize growth and marketability.

Antibiotics harm fish and aquatic life. Image: Giant Group, Georgia Aquarium, Wikimedia.

Other ways animals are affected? Aquatic life itself is changing: so much estrogen has entered rivers and ponds that male fish are showing genetic changes including the development of intersex fish, especially downstream of wastewater treatment plants: notable is Washington’s Potomac River.

Filters are one approach: water treatment plants have been successful at filtering out ibuprofen but couldn’t catch diclofenax, another pain reliever. Chlorine used in drinking water treatment does reduce bacteria and also degrades acetaminophen and the antibiotic sulfathiazole, and also carbamazepine (by 75%). Still, chemicals are getting into our bodies simply by turning on the tap: Southern Nevada Water Authority found antibiotics, antipsychotics, beta blockers, and tranquilizers in the drinking water as far back as 2010. It is only getting worse.

SOLUTIONS

Pharmaceutical systems include manufacturing, distribution, consumption, disposal, and waste treatment: each step of the process offers opportunities for intervention and innovation. Regulations, at a national, local, or global level, can be effective: compliance is now an industry with consultants like Stericycle with programs “designed to meet regulatory requirements.” Of course, pharmaceutical businesses have in-house programs and systems, including segregating hazardous waste pharmaceuticals that are then sent to a Treatment, Storage, and Disposal Facility (TSDF). It’s a big business: UBS and Vanguard are investors, along with 500 other financial funds. Stericycle has 22,000 employees: competitors include Republic Services with 36,000 and Waste Management with 42,000 employees. It’s a business of the future: pharmaceutical use shows no sign of decreasing, although there is a movement to encourage safer drugs.

Jardine Water Purification Plant, Chicago, Illinois, USA. Image: wikimedia.

Nations and cities can take action. Water facilities such as the Jardine Water Purification Plant in Chicago, Illinois, world’s largest by volume, draws water from the American Great Lakes for distribution to 390 million urban residents. Research and innovation here could lead the way. In Europe, Germany invested one billion euro in the last two decades to water infrastructure including wastewater collection and treatment, in some ways advancing beyond the EU’s Council Directive 98/83/EC.1

Waterways themselves can innovate. When the Roman Aqueducts were built, it was due to an increasingly polluted Tiber River. When London’s water supply from the Thames became problematic, a public-private system was developed: the New River. Will the Grand Canal of China, part of the Belt and Road Initiative, lead research and action to improve the aquatic environment ? Might Inland Waterways International champion ways to improve the health of rivers and other created waterways?

SOLUTION: YOU – What can you do?

Don’t purchase bulk or volume packaging, avoiding accumulation of unused or expired chemical formulations.

Never flush unused medications, vitamins, or supplements down the drain.

When you must dispose, trash/landfill is preferable to flush/water. First, remove pills from container (recycle container),  then crush the pills, add a bit of water, and seal the result in a strong plastic bag before placing in trash.

Water Rights

Yamuna River, India, now has personhood rights. Image: wikimedia

We are the water planet. Throughout history, we have determined water rights in agreements and laws like the Colorado River Compact and Itaipú. But now, perhaps we are reaching a new era of respect for water. Does water itself have rights? New Zealand granted “personhood” rights to the Whanganui River, sacred to the Maori people and to the environment. India followed that precedent, establishing personhood rights for the Ganges and Yamuna rivers; India granted rights for the rivers as a whole including regulation of construction of damsColombia mandated the rights of Amazon forest and the Atrato River, setting a law for an intergenerational pact for the Colombian Amazon. In the USA, Ohio will vote on personhood rights for Lake Erie. Bolivia may have established the broadest environmental rights with the Ley de Derechos de La Madre Tierra (Law of the Rights of Mother Earth). It would seem that precedent has been established. What waters will next be granted rights?

WATER: Labeling the Future

Should we label products for water, land, and environmental facts? Image: wikimedia

Look at the fine print. Many items on grocery store shelves commonly have labels revealing the amount of carbs, sodium, or sugar in the product. Is it time to label information about environmental, land, and water use? For example, dairy milk, one glass per day for a year, requires 7,000 square feet (650 sq. m) of land – that’s the same size as two tennis courts. That year’s worth of dairy milk also requires water use: 2,588 gallons (9,800 liters) of water  – that’s the same amount as 150 bathing showers, each lasting a luxurious eight minutes. Switch to almond milk? It requires less water to produce than dairy, or soy, milk; but soy generates more greenhouse gases than almond.

Rome’s Trevi Fountain. Image: wikimedia.

There’s precedent for labeling environmental water sources. One of the features of water from the Roman Aqueducts was the taste and freshness of each particular spring flowing from the surrounding hills. Water surveyors used methods such as studying the health and complexions of village folk, determining water quality by such evidence. In the urbs, labeled and name-branded waters competed for consumer preference. Even today, there is a cafe in Rome advertising cappuccino made from the sweet, fresh waters of the Aqua Virgo.

The global food supply chain generates 13.7 billion metric tons of carbon dioxide, or 26% of human-caused greenhouse gas emissions, according to Poore and Nemecek. Agriculture covers 43% of arable land; 2/3rds of the freshwater withdrawals are for irrigation. The United Nations illustration, above, indicates systemic factors regarding water, energy, and food. Wonder what you’re consuming – in food and natural resources? Even if governments don’t require such labeling, could industry groups initiate the trend? The beverage and brewing industry recently agreed to display nutrition information on beer products, but most is in small-type or hidden at the bottom of a six-pack. Coors, Corona, Guinness, and Heineken complied, and now Bud Light will display more visible listings of the amounts of barely, hops, rice – and water. According to VP of Marketing for Bud Light, Andy Goeler, younger consumers want to know and are “really in tune to ingredients.”

Building the Vegetable Kingdom

“Carrots of many colors” Image: USDA, Agricultural Research Service, IDK11611-1. Wikimedia commons.

Building a better world – with carrots. That crunchy veggie could be used to strengthen concrete, improving construction techniques, and the environment. Blending carrots into building products makes those materials as much as 80% stronger, according to Mohamed Saafi, Professor and Chair in Structural Integrity and Materials at Lancaster University. Not only stronger, carrot-fortified concrete also develops fewer cracks – the carrots seem to act like superglue – so less cement is required, resulting in a lower carbon output. Could it make a difference in our world? Yes. Cement is the source of 7% of global carbon dioxide emissions.

Ancient Rome built superior roads and bridges by using materials strengthened by a mix-in of volcanic ash. The Great Wall of China was initially built by compacting reeds and mud, a combination that proved stronger and easily scalable, since the materials were available onsite, important when building a 13,000 mile wall. Bridges on the Grand Canal are another example. Mix-ins have long strengthened building materials.

Meanwhile, the next time you munch on a carrot, consider what Christian Kemp-Griffin, CEO of CelluComp, explained: “Those fibers have strength characteristics in them. It’s the building blocks of the strength of a vegetable.” Because carrots contain so much water, only a very small amount of cellulose of a carrot will alter the property of cement, because water changes as cement hardens. Kemp-Griffin continued: “It’s not the physical fiber that’s causing the strength. It’s the way it holds water. There’s a chemical reaction happening between the fibers and the cement.”

Finally, it’s free, or almost free. CelluComp uses industrial leftovers: carrot peels from those machines that give you pre-cut carrots. Beets are next; there’s a lot of beet pulp after sugar production; 20% of the world’s sugar is made from beets. Brazil leads in sugar production (mainly cane sugar, the other 80%); but building markets may take note of Russia, France, USA, Germany, and Turkey, largest producers of sugar beets. Or, building big with carrots may happen in New Zealand, home to Ohakune, and the big carrot pictured above.

Voice of the Future 2018: Stephen Hawking

15 June 2018, Westminster Abbey, message sent: 15 June 5518, 1A 0620-00, message received. As Stephen Hawking’s mortal remains were interred between Isaac Newton and Charles Darwin, the visionary physicist’s words were sent, with music composed Vangelis for the occasion, to the black hole closest to earth, 3500 light years away.

Hawking’s Voice of the Future is “a message of peace and hope, about unity and the need for us to live together in harmony on this planet,” stated Lucy Hawking, the physicist’s daughter.

Black Hole 1A 0620-00 calls home a binary system with an orange dwarf star. According to Günther Hasinger, European Space Agency’s Director of Space, “when Stephen Hawking’s message reaches 1A 0620-00, it will be frozen in the event horizon.”

Ave atque vale is a phrase credited to the Roman poet Catullus, who wrote in elegy numbered 101: Atque in perpetuum, frater, ave atque vale, meaning “And for eternity, brother, hail and farewell.” In 2018, the poet’s words rang along with the chimes of Westminster.

Stephen Hawking, who wrote A Brief History of Time, may have changed the definition of the temporal dimension.  For Hawking’s TED Talk, “Questioning the Universe,” click here.
