Water Sanitation Begins at Home

After spending two years working to develop water and wastewater infrastructure in Mali, I have been back in New York for two months and have learned to see the place that I call home in a brand new light. People often ask me how I am adjusting back to America, and if I don’t have time for a real conversation I tell them “It’s really cold!” or “I really enjoy going to the supermarket!” But if you have the time to listen, I would like to share with you how after everything I’ve seen and done in the most underdeveloped corners of Africa, being back in America is in some ways quite unsettling – I would be dishonest if I didn’t tell you that I am thoroughly disappointed with my local tribe and clan.

In Mali I lived amongst a society of isolated, impoverished, unlettered farmers who have spent the past however-many millennia suffering and dying from completely preventable giardia and dysentery. I would go to a Minianka family’s house and see that they arranged their compost pile full of donkey manure only a few meters from the uncovered well from which they drew all of their drinking water, or that they had dug their well on one side of a mud-brick wall and that on the other side of that wall the neighboring family had built a latrine. I will admit that in moments of weakness I sometimes succumbed to pejorative views of the local culture – I thought that my community’s nonchalance, disinterest and at times visceral resistance to modern methods of sanitation were exclusive to the Minianka tribe. I would share these frustrations in letters to my friends back home and they would express their disbelief; one wrote back “My dog and your cat understand that they shouldn’t shit in their drinking water – how is it that these people haven’t figured out such a basic instinct of animal survival?”

Now that I’m back in America I can rest assured that the people of my home country aren’t simply pulling down their pants and defecating in the streets like many did in Sanadougou, and just about everyone in New York can tap water from groundwater wells or municipal water grids with indoor plumbing systems in the comfort of their kitchens. But apparently even in the supposedly-developed West, in the wealthiest corners of the wealthiest states in the wealthiest country in the history of human civilization, even my fellow tribesmen have yet to act on the basic truth that my friend’s dog and my cat grasped so well.

This rude awakening came to my attention when I visited my friend at her home here in South Salem, New York and asked for a drink of water – and she proceeded to take a bottle of Poland Spring out of the refrigerator.

“That’s not necessary – I prefer tap water.”

“No, actually it is necessary.” my friend explained, “Our tap water is unpotable!”

I was dumbfounded. “You mean to tell me that I just spent two years working to bring potable drinking water to an obscure tribe in a remote corner of Africa – but here in New York we can’t drink the water?”

“I’m afraid so. Give it a taste.”

I filled a glass with water from the sink, took a sip and spit it out in disgust. “This water is so salty it tastes like contact lens solution!”

“That’s because our chloride levels are off the charts! I’m pretty sure that it’s because in 2008 the Town of Lewisboro discontinued the use of sodium chloride to de-ice the roads during the winter, so beginning in the winter of 2008-2009 they started using magnesium chloride under the reasoning that it is less harmful to the environment. However, magnesium chloride is only half as effective in reducing ice as sodium chloride – so they had to use twice as much.”

She pointed out the window, “If you see right there – that’s our well, and it’s only a few meters away from the road. So when the snow and ice melt, much of the magnesium chloride flows downhill as runoff and then percolates down to the groundwater – the groundwater our well pumps up as our drinking water. Our chloride levels went through the roof – that’s why our water is so salty! ”


My friend explained that she started going to the supermarket to buy bottled water in bulk – but she needed to transport such an unwieldy mass of water every week, soon she found herself having to go to the supermarket every three or four days that she and her husband realized that they needed a more practical long-run solution. They signed up for Nestlé Waters to deliver five 5-gallon bottles of Poland Spring to their door every month for $39.95. Even though they are paying taxes to the Town of Lewisboro to ensure clean water – and de-ice the roads – they also to pay $479.40 every year to Nestlé Waters in recurring water expenses.


My friends in South Salem have to use Poland Spring not just every time that they want to drink a cup of water, but every time they make a pot of coffee and every time they cook spaghetti and every time they brush their teeth. Their dishwasher was leaving white saline residues on their dishes, it was corroding their stainless steel knives – and dishwashers can only operate with tap water, so if they didn't buy a water softener they would have to do their dishes by hand with Poland Spring.

The tap water is so salty here in this neighborhood that it can only be used for bathing, washing clothes, flushing the toilet and irrigating the lawn and garden. Though in all fairness, perhaps the drinking water supply in South Salem is not as bad as the foul wells my erstwhile neighbors drank from in Sanadougou in that at least it isn’t soiled with fecal matter. But that’s a lot more than they can say in Amherst, Massachusetts…

I recently drove up to my old college town to say hello to some old friends, including my Professor Jessica Wolpaw Reyes. If there is anyone in America who understands the value of clean water, it would be Professor Reyes; she is an economist specializing in the niche subjects of environmental economics, the economics of water and health and how these subjects intertwine. In fact, she has been making waves with a seminal paper in which she linked the levels of lead in the drinking water to crime rates. Her latest research is concerned with the adverse health effects of plastic packaging of food and beverages.

When I arrived at the Reyes’ household, I was surprised to watch my Professor open up the fridge and serve her kids from a plastic jug of Poland Spring. “Isn’t the conclusion of your next paper that we should stop drinking plastic-bottled water?”

“Yes, it is pretty terrible and I would certainly prefer not to, but my choices are limited. The town just discovered E. coli and fecal coliform in the drinking water, so unless I am going to boil or chlorinate every last drop of tap water we use to drink and cook and clean the dishes – which is quite impractical, frankly – I have no choice but to buy bottled. As much as drinking from plastic bottles might cause some forms of disease in the long run, at least it won’t cause immediate gastroenteritis…”

“… So you’re telling me that the municipal drinking water supply is contaminated with fecal matter – here in Amherst, Massachusetts…?”

“That’s precisely what I’m telling you. If you thought that these problems were exclusive to Africa, then you have a lot to learn about the sorry state of water policy in America.”

It turns out that the presence of E. coli and coliform in the Amherst water supply was probably fostered by three successive water main breaks over the course of October. Since these breaks were located fairly close to the water treatment plant they leaked vast quantities of chlorinated water, and as chlorine kills bacteria and microorganisms it breaks down itself, so as the newly-chlorinated water was flowing out of the broken mains chlorine levels in the later segments of the municipal water grid dropped to such low concentrations that E. coli and fecal coliform cultures could flourish unabated.

Just as a chain is only as strong as its weakest link, the quality of water provided by a given plumbing system is only as reliable as its weakest pipe. All there needs to be is one single pipe which over the years (or only months) of chemical or physical duress has degraded to such a degree that it can no longer withstand the pressure of the water being pumped through it; eventually cracks form and the pipe will begin to leak. The pressure at the end of a hydraulic system is contingent on there being a constant volume of water inside, so if water is coming out at multiple apertures, pressure will drop accordingly. If there’s just a tiny little trickle at the end of a remote line, water pressure will reduce somewhat and water quality will decline – but in the grand scheme of things that’s not so terrible. What’s terrible is when a plumbing system has cracked in so many places or there’s one break so big that water is gushing out in such massive volumes that the pressure of the hydraulic system plummets so low that it becomes negative.

Negative pressure means that instead of pushing out the hydraulic system will be sucking in – usually air, which leads to rust buildup. This is what happened with the solar water pump-to-tap system we renovated in Sanadougou; the pipes were so damaged that water pressure was usually so insufficient that one could hardly get any water from the taps, and when the water did come it was so discolored and bad-tasting that no one wanted to drink it. If a plumbing system marked by leaking pipes and negative pressure were surrounded by nothing but air, it would probably be contaminated with only iron, manganese and iron bacteria – which is certainly bad, but it’s not the superlative worst thing that could happen to the water supply.

Off the top of my head, I can’t think of any kind of water that I would be less enthusiastic about drinking than water contaminated with fecal matter. Writing from personal experience, take it from me that E. coli, coliform, giardia cysts and amoebas rank among the bottom of things that you ever want to down in your water glass. Okay… Vibrio cholerae would be worse – though I have no personal experience with cholera to serve as a reference point… Mercury, selenium, plutonium would be much worse – but these kinds of high-tech pollution are fairly complicated, and to be frank we Americans are nowhere near close to mastering even the basics of sanitation so for now I’ll just stick to the fundamentals; e.g. how to keep shit out of our drinking water supply.

Likewise, the most immediate problems of water sanitation are related to the fact that the water mains transporting potable drinking water from the treatment plant aren’t the only pieces of infrastructure that break. Just as water mains corrode and crack, so do the outflow pipes transmitting blackwater from toilets and greywater from sinks and washing machines and dishwashers to the municipal wastewater treatment plant. Or in low-density communities where wastewater is disposed via decentralized septic tanks and leach fields, a household’s sewage is jettisoned directly into the soil under the assumption that the wastewaters will be transmitted in such modest volumes that the soil will have the capacity to remove all of the impurities and the wastewaters can eventually merge with the groundwater without contamination.

However, all too often the effectiveness of a septic system is grossly overestimated or plots of land are subdivided and a neighborhood becomes exponentially denser with no commensurate improvement in wastewater infrastructure, and as the inadequate wastewater infrastructure is overused the ground becomes supersaturated with sewage.

If the water table is high and the capacity of the septic systems is insufficient for the population, then the groundwater will probably be contaminated with sewage and all of the dangerous bacteria and microorganisms that come with it.

This was precisely the case in the community built around Peach Lake in nearby North Salem. The oldest houses along the shore of Peach Lake date back from the 1900s, 1910s and 1920s when this community was just a small cluster of wealthy Manhattanites’ summer cottages – and when these oldest houses were built a century ago they were equipped with small septic tanks intended to be used only a few months every year. Though by the 1950s the sprinkling of summer cottages along Peach Lake had developed into full-blown suburban neighborhoods with more than 700 homes inhabited year round, they had grown to such a size and density that they really needed a municipal sewer system and a wastewater treatment plant – but all of the residents of this lakefront community were still disposing of their sewage with miniscule septic tanks meant to service the occasional Coolidge-era vacationer.

Lakefront communities are almost by definition situated on top of extremely high water tables – and Peach Lake was no exception – so all of their raw sewage was overloading the soils and contaminating the groundwater which in turn flowed to the lake. And eventually the pollution had built up so badly that by the 1970s Peach Lake had become a veritable cesspool; phosphorus levels were so high that algae blooms choked off the rest of the aquatic ecosystem, bacteria counts were so high that the town of North Salem had to forbid swimming and close the beaches.

If this kind of water pollution had happened to just any old pond, that would be pretty bad for the ecology of the pond and the health of the families in its immediate vicinity; however Peach Lake is not just any old pond – it’s a part of the Croton Watershed which contributes to the system of reservoirs which provide the supply of drinking water for New York City.

Consequentially speaking, the sanitary practices of my fellow New Yorkers in North Salem were really no better than those of the Haitians who are shitting upstream and drawing their drinking water downstream in the same Artibonite River. The only reason why people in the Bronx and Manhattan aren’t suffering from a cholera outbreak like there is now in Port-au-Prince is that the NYC Department of Environmental Protection operates what is one of the grandest water treatment systems ever established in the history of human civilization.

But I digress – back to water mains. A broken water main per se is such a grave threat to public health because a disruption in the supply of treated water can disrupt the chemical equilibrium throughout the rest of the entire water grid, and if chlorine levels fall like they did in Amherst this past October then the quality of the water in the main is free to return to its natural state i.e. full of bacteria. But keep in mind that if so much water is being lost that the pressure is not just low but negative, the hydraulic system is going to suck in whatever matter it can in the immediate vicinity of the break. Maybe the hydraulics will only suck in oxygen – not the end of the world. But imagine what happened when water mains inevitably broke around Peach Lake in North Salem…

Most households connected to a municipal water system are also connected to a municipal sewer system. When crews of masons and pipefitters and plumbers build one set of pipes, they usually build the other along the same routes because it is the most efficient method of construction. Hence it would be more than fair to say that most water pipes are built in the same neighborhoods as each other – usually they are built one on top of the other. Without proper maintenance, water pipes break. Without proper maintenance, sewer pipes break. And thus without proper maintenance, the water mains which were built to bring potable drinking water to its consumers can break and develop negative pressure and suck in raw, untreated sewage.

This scenario is more than just a hypothetical possibility; seeing that water pipes are generally laid in the same places where sewer pipes are laid – or septic systems, or storm drains or fire hydrants where dogs defecate, or fields enriched by organic fertilizer, or woods where wild animals lay their droppings – it would be fair to assume that any significant water main break is going to lead to some form of contamination of the water supply at least downstream from the aperture. This happens all the time in towns and cities far and wide in every region and climatic zone…

I cannot emphasize enough that every time a water main breaks like this – even when it doesn’t rupture with such sensationalist bravado – it carries grave implications for public health. A broken water main isn’t like a pothole in the street; it’s not a nuisance that we can just deal with until the next scheduled maintenance. Every time that a water main breaks, at least the portion of municipal drinking water supply downstream from that main should be considered as though it is contaminated with sewage. When you see a water main break in the United States of America, that means that everybody who depends on this system for drinking water is now at risk for the sort of waterborne diseases that you would expect to see in some Third World country – because when our massive water systems malfunction we might as well be drinking from some fetid hole in the ground. Every time that a water main breaks it is in all probability not just a freak occurrence – it is most likely an indication that the entire water and wastewater infrastructure upon which that populations depends is old and decrepit and that it has probably been grossly neglected and shortchanged of tens of billions of dollars and however many decades of necessary repairs.

So think of the ramifications that decrepit infrastructure led to in a small town like Amherst or North Salem and try to imagine how those problems could intensify and cascade in a much larger, more densely-populated metropolitan area of multiple millions of people. A good case study would be to see what happened this last May when a 10-foot wide underground water main connecting the Quabbin Reservoir to the municipal water system serving Boston and its suburbs ruptured in Weston, Massachusetts. To call this a “leak” would be an understatement – the broken main was dumping 8 million gallons of water into the Charles River every hour for 8 hours until the Massachusetts Water Resources Authority was able to shut the valve and cap the flow.

Governor Deval Patrick issued a state of emergency and boil water orders for over 2 million people in 30 communities; “This water is not safe for drinking” he declared. Mayor Thomas Menino also issued a state of emergency in Boston, alerted residents about the boil water order through the city’s reverse-911 system, distributed fliers and sent police officers to the streets declaring the boil water orders with bullhorns.

Unlike in Amherst where a boil water order was an inconvenience, in a densely-populated metropolitan area the size of Boston this was a full-fledged public crisis. Even if the city and the state issue boil water orders, this is not an option for the hundreds of thousands of Boston residents who don’t have functioning stoves or students who aren’t allowed to have hot plates in their dormitories. Not only private households but businesses were not able to function without immediate access to tap water; for restaurants, hotels, movie theaters and baseball stadiums that need water as an input in the food and beverages they sell, which have to be able to serve food and beverages at a certain temperature in large quantities, boiling water was simply impractical. The only way that people could go about their daily life was by stockpiling bottled water.

But the fact of the matter is that the free market in commodified bottles of water – in all of its efficient glory – has proved unable to meet the demand for potable drinking water. Living off of bottled water might be feasible in a small town like South Salem or even a large town like Amherst, but only because these are communities where the majority of residents are either college students whose respective schools provided for bottled water supplies in their dining halls and dormitories or they have cars and can drive down the road to a shopping center. Even if the local Stop N’ Shop is sold out of Poland Spring, those with cars can just drive to the supermarket in the next town over beyond the boil water order zone. Though in a city like Boston where the majority of residents don’t have cars and the T doesn’t go anywhere beyond where the boil water order was in effect, the stocks of bottled water sold to supplement the municipal tap system were too modest to supply the entire metropolitan population of 2 million. Stores were even sold out of sparkling water! Bostonians had to resort to brushing their teeth with seltzer! Bottled water was in such short supply that Governor Patrick had to call up the Massachusetts National Guard to deliver emergency drinking water supplies.

Bottled water has its virtues; it’s convenient, it carries the dependability of any brand-name consumer item, and it’s cheaper in the short run than investing in the durable infrastructure necessary to make tap water potable. Professor Reyes – as much as she’s against it – drank Poland Spring for the duration of Amherst’s boil water advisory. Some households – like my friends in South Salem – have given up on tap water entirely and have been drinking bottled water exclusively for years now. But as individuals and moreover as a society, we really cannot afford to rely on bottled water for our long term needs. I’m not even addressing the environmental costs of generating so much unnecessary plastic waste; to subscribe to Nestlé Water’s home delivery services, one has to pay a deposit of $20 for the dispenser – $22 for the stainless steel model, one has to pay the continued subscription costs of $32.96 for three, $39.95 for four, or $46.80 for five 5-gallon bottles of Poland Spring delivered to your doorstep every month. A year’s supply of home-delivered Poland Spring for a family of four would cost $581.60 – plus taxes. For a family with two professional-salaried breadwinners, $581.60 isn’t going to break the bank. But for a middle class family that makes $50,000 a year, the $581 of bottled water would add up to 1.7 percent of their total household budget – that’s a significant sum of money. In comparison, the Bush tax cuts of 2001 saved a family making $50,000 per an average of $1,825 each year.

My cousins Bob and Jane in Stamford, Connecticut have had chronic water problems with the water in their house that is pumped from their 50-year-old well; the water is turbid and acidic and it is full of high levels of iron, iron bacteria, manganese, nitrates and chlorides. They technically can drink their tap water – it is potable – but the water looks opaque, it tastes terrible, the chlorides are corroding the pipes and Bob’s doctor thinks that the high iron levels might be the cause of his blood pressure problems. So for 21 years they have been subscribing to Poland Spring’s home delivery services for the total cumulative cost of more than $12,000.

But recently Bob and Jane decided that enough was enough and they are now hiring plumbers to install a brand new well storage unit for $1,800 and a water softener for $2,800. “Wells were never meant to last forever – to just keep putting and putting this off is sheer insanity!” Bob explains, “It’s costing me an arm and a leg, but compared to what bottled water costs these investments are actually quite reasonable.”

We as a people have to start approaching our national crisis of inadequate water infrastructure the same way as my cousins Bob and Jane addressed the problem with their well and realize that it’s not a matter of paying or not paying. The choice we have to make is whether we are going to pay indefinitely for the damage caused by dilapidated water systems and tremendously expensive band-aids – or whether we are going to address the root of the problem and invest in durable water infrastructure so we can have clean drinking water now and save money and improve our economy in the long run.

Back to North Salem, after decades of environmental consultations and town meetings and board resolutions the communities around Peach Lake are finally getting the wastewater infrastructure that they need. Last year Congressman John Hall was able to secure $7 million of funds from the American Recovery and Reinvestment Act to pay for the construction of neighborhood sewage collection systems, a pump station and a treatment plant.

“Funding clean water infrastructure is a smart investment that will help protect public health and create long term value for years to come. This project will create local jobs and reduce the burden on local property taxpayers” Congressman Hall explained, “When I cast my vote earlier this year for the American Recovery and Reinvestment Act, this is exactly the kind of investment that I knew we needed in the Hudson Valley.”

We need to implement this kind progressive clean water agenda on a national scale. Our water infrastructure is falling apart because much of it dates back from before the Roosevelt administration – the Theodore Roosevelt administration. Especially in older cities like Boston, New York, St. Louis and Chicago many of the water mains and sewer pipes date from the Civil War era. Almost everywhere we need to step up monitoring, maintenance and basic repairs, but in many places after more than a hundred years of use and neglected maintenance the infrastructure has degraded so badly that it is beyond the point of no return. Here in Westchester County, much of the Croton Watershed which provides New York City’s drinking water supply dates back to its original construction in 1842 – in some places, the population of Manhattan’s drinking water is still transported via wooden aqueducts. Assuming that technology might have improved after a hundred years or so, the mere upkeep of antediluvian infrastructure will not suffice for our present needs. If we are to have a functioning society and economy we have to build significant swaths of our grids anew and lay brand new water mains and sewer pipes and construct treatment plants utilizing modern 21st century technology.

There are some members of Congress and elements of this administration who do understand the gravity of our inadequate water systems and who have begun to take action to finally invest in the modern infrastructure that we need. Though experts on these matters are contending that the Obama administration’s actions thusfar have been a good start – but nowhere near enough to repair, replace and modernize all of our corroded water mains, decrepit sewers and obsolete treatment plants. In 2002 the Environmental Protection Agency released a report estimating that the United States will have to spend as much as $390 billion over two decades simply to replace outdated wastewater infrastructure systems and replace them with new ones. In 2008 the Agency reported that the nation’s publicly-owned water treatment plants alone needed roughly $202.5 billion worth of investment. The American Society of Civil Engineers goes even further and estimates that in order to simply maintain our current levels of sanitation and drinking water quality we will need to invest $255 billion in our water and wastewater infrastructure – $109 billion more than currently-projected outlays – just over the course of the next five years. These numbers might sound staggering, but when you consider that over the past decade Congress has allocated $751 billion in emergency spending measures to fund the war in Iraq and $336 billion for the war in Afghanistan, an additional $109 billion in emergency spending to fund critical investments in our water and wastewater infrastructure in America actually seems quite modest.

As the 112th Congress convenes in January and begins what is certain to be a long, drawn-out budget showdown, lawmakers would be wise to heed the advice of the Environmental Protection Agency and the American Society of Civil Engineers and provide for increased spending on water and wastewater infrastructure. Understandably, this is a time when public officials are going to have to make tough choices between tax cuts, military bases, schools and roads – and water and wastewater infrastructure might unfortunately take the cut because the very most public of public goods doesn’t have a constituency as well-organized as the Oil Lobby, the Farm Lobby or the Defense Contractor Lobby. But unlike tax cuts for millionaires or the next generation of nuclear weapons, we don’t have a choice as to whether or not we are going to pay for our water systems.

We can choose to pay to maintain and repair and modernize our infrastructure now when it’s merely expensive, or we can choose to pay for our infrastructure later after all of our sewage treatment plants have collapsed and all of our drinking water systems are contaminated with fecal matter and all of our infrastructure is so unsalvageable that we have to replace everything from scratch – then it’s going to be really¸ really, really expensive. Paying for adequate maintenance is an incredibly more frugal policy than putting it off until we have to pay for more expensive repairs, paying for repairs is likewise more frugal than just letting systems collapse and having to pay for unnecessary new construction. I cannot emphasize enough that the rationale for investing in water infrastructure now as opposed to later is inherently conservative in nature. This goes out to all of you who can't stand wasteful spending; if we don’t invest in necessary public infrastructure, can you imagine how much more the American people would have to spend on Poland Spring home delivery? If you think that Medicare, Medicaid and Obamacare are expensive now, can you imagine what the costs would be like when the American people are suffering from endemic gastroenteritis and giardia and dysentery?

Back in Sanadougou, my friends in the Minianka tribe stoically accept these waterborne diseases and the ensuing poverty and misery and death that define their lives as simple facts of life. When the Peace Corps sent me to live amongst them, my role in this foreign society was to shine a light on these problems that no one wanted to talk about, to connect the dots between the causes and the symptoms, and to show the Miniankas that if only they open their minds to change and invest the time and resources necessary to obtain clean water, then we could completely and thoroughly prevent all of this disease and stagnation from ever existing in the first place.

And now that I am back home, I think that my role in my own society might be more or less to same – though maybe it might be more complicated as my countrymen seem to think that the sheer mass of our GDP or our military might somehow set us apart from the basic facts of pathology. Indeed, we might have advanced computer technology and a developed commercial economy centuries and millennia ahead of Haiti, Kenya, Afghanistan or Bangladesh – but that doesn’t make the American people immune from the same bacteria and parasites that are keeping the various cultures of the Third World mired in disease and poverty. The presence of these contaminants in our drinking water does not have to be a fact of life, we can very easily change our practices and improve our infrastructure without sacrificing our cultural heritage and without breaking the bank, but with the same combination of obtuseness and reckless pursuit of absolute convenience, we – like the Miniankas who refuse to wash their hands with soap – act as though we are content with living amongst our own filth. I can forgive the Miniankas for their inadequate sanitation so long as they can plead ignorance to the science of disease transmission; I cannot extend that same generosity to my fellow Americans.

Do we in America really live in an incomparably advanced civilization? Are our ways in fact superior to the Germans, the Russians, the Chinese, the Indians… the Miniankas? Or are we just conceited by the intoxicating sophistry of American exceptionalism?

I think that in evaluating the relative greatness of a society, a good place to start would be to analyze the development of their sanitation practices and infrastructure. Upon this rude awakening to the realities of our water policy in America, I cannot help but share the sentiments of my late Grandpa Leon who used to shake his head and conclude, “We’re still swinging from the trees”. Though I would like to hold out hope that my people will be able to evolve in our ways – perhaps to the level of my friend’s dog or my cat – and that one day we will finally begin to keep our shit out of our drinking water.

Help Fund Pilar's Nyegen Project!

Though the eponymous hero of this blog can no longer volunteer his own ditch–digging skills, the brave activists of Operation Sphincter Plug continue their valiant effort to rid the world of gastrointestinal disease. Continuing this imperative work in another village down the road from Sanadougou is Peace Corps Volunteer Pilar Lyons of Pine Bush, New York. Pilar is a civil engineer with a special zeal for water and wastewater infrastructure!

Pilar’s village is much smaller than Sanadougou – only about one thousand people; however, it has even more dire sanitation needs. This particular Minianka village lies atop soft fertile soils adjacent to a series of seasonal ponds with a very high water table – only 1.5 meters below ground in some places. Though this is a prime location for agriculture, since the water table is so high and the soft soils are not supported by solid rock, their “traditional latrines” built from mud and logs often rot and collapse while some unlucky person is squatting on top of them. Even worse, the high water table and soft soils mean that the groundwater which feeds this village's wells is particularly susceptible to contamination from the unlined latrine pits; in other words, their drinking water is directly polluted with human fecal matter. Without any means of containing wastewater, raw sewage flows out into standing puddles in the street which serve as fertile breeding grounds for malaria-spreading mosquitoes, as well as filth flies and cockroaches which carry giardia cysts and amoebas into the people's food and drinking water.

Inadequate sanitation in a Minianka village is not just something icky – it is the reason why giardia, dysentery, hookworm and malaria are absolutely endemic in this society, it why two out of every five children die before the age of five, it is why so many adults cannot work in the fields because they are sapped and emaciated by dysentery. Without the monetary wealth to purchase reinforced concrete and plastic tubing necessay to build adequate sanitation infrastructure, these poor Miniankas are mired in a cycle of filth, disease and poverty.

A few months before I packed my bags for Ameriki, Pilar biked over to the mud mansion of Xanadu with two masons from her village both named Daniel Dembele. They came to inspect the many dozens of nyegens and soak pits we had built throughout town. My main man Sidiki Sogoba taught the two Daniels how he assembles proper latrine platforms so that they could apply this trade in their own community. Sidiki doesn't mind the competition, because "We need so many skilled masons in every village in Mali. Even near Sanadougou, we need so much work that I could never do it all."



Now Pilar and the two Daniel Dembele’s are committed to organizing a village–wide sanitation campaign similar to the one which Sidiki and I conducted in Sanadougou. With your help, they would like to build 30 concrete latrines with lined latrine pits to safely store solid waste and a combintion of soak pits and infiltration trenches to safely store liquid waste underground in such a way that it does not directly contaminate the groundwater and it cannot be spread by flies and vermin to indirectly contaminate the food and water. The villagers who would like to participate in the program will have to procure all of the sand, rocks and gravel and either contribute or pay for all of the necessary labor; 27 percent of the total cost. Funds donated through the Peace Corps Partnership will go to pay for cement, rebar, plastic pipes, plastic sheets and a few masonry tools which the town does not have at their disposal.

Trench Peacefare

This one trick pony has expanded his repertoire. As loyal readers should know, the people of Mali suffer from completely unnecessarily high rates of giardia, dysentery and explosive diarrhea because the raw sewage from their “traditional latrines” flows out into the streets and the entire population is exposed to the dangerous pathogens which cause these illnesses and continue the positive feedback loop by making their way into other people’s mouths. Sewage is both a danger to public health and also a necessary byproduct of human life itself, and so this blog’s eponymous hero is busy spending the prime years of his youth and your tax dollars building modern latrines equipped with concrete floors and soak pits: a rudimentary septic tank technology appropriate for cultures in this harsh Sahelian climate with few financial resources and building materials.


In the flat center of Sanadougou where I live, the water table lies almost perfectly uniformly between 7.5 meters below ground level at the peak of hot season and 4 meters below ground level after the groundwater has been recharged by 4 months of rainy season. In the center of Sanadougou where about 3,800 of the 4,400 permanent residents live, development-minded villagers have been digging soak pits 1 meter deep and varying in diameter (usually about 1 to 1.5 meters) depending on the number of people in their households and the volume of wastewater generated by their respective nyegens. Since the pathogens originating in wastewater can usually seep up to half a meter through hard-packed soil and sedimentary rock, the water table should never come closer than 2.5 meters to the sewage generated by these modern latrines and thus the groundwater consumed through wells and pumps should be adequately protected from direct contamination by human fecal matter.

However, even within the demarcated borders of Sanadougou there are some places where the soak pit is an inappropriate technology. Namely, there is an outlying neighborhood called Filablena which is significantly lower in elevation than the rest of the town and sits around a couple of large seasonal ponds. Here the water table varies between 5 meters below ground level at the peak of rainy season and 1.5 meters below ground level after rainy season.


The wells here are so shallow, and with less rock they are cut into nothing but soft soil which is much more permeable and conducive to groundwater flows. The pressure in a well is somewhat less than within the soil, so the water levels of wells are slightly higher than the water table; in Filablena during rainy season, the well water surface is only slightly less than a meter below ground level.


If we built 1 meter deep soak pits here like we have in the rest of Sanadougou, soak pits would in fact exacerbate the water sanitation problem by directly polluting the groundwater with raw sewage. That contaminated groundwater would then eventually make its way to people’s wells from which they get the bulk of their drinking water. The absolute worst-case scenario would be that contaminated water makes its way into the seasonal ponds and – though it probably wouldn’t be as obvious as the ones which form behind "traditional latrines" – render them into gigantic seasonal cesspools.

In Filablena we are just beginning to introduce a specialized technology: the infiltration trench. An infiltration trench serves the same function as a soak pit in that it contains the wastewater emitted from “traditional latrines” underground so that it cannot serve as a fertile breeding environment for filth flies and mosquitoes and cockroaches and a vector for all sorts of disease. It has to be able to store roughly the same volume of wastewater as a soak pit, but in an environment where the water table is prohibitively high an infiltration trench must be dug at a much smaller depth. In truth, the volume of a soak pit is only really important so long as it briefly stores wastewater before in seeps into the surrounding soil and rock; what is much more important is the surface area which determines the rate of discharge into the ground where it is safe and isolated from human water and food supplies. Where there has not been a lot of room to maneuver, we have solved this problem by simply reducing the depth of our soak pits and increasing the diameter accordingly.

Infiltration trenches take that ideal of minimal depth and maximum surface area even further. First I found a group of Filablenakaw interested in rebuilding their nyegens, measured their dimensions and assigned them lengths of plastic piping between 4 and 6 meters in length. Then we took an afternoon and pierced holes in them; we took a dozen large nails and placed their ends in the fire until they became red hot, and with protective work gloves we held pliers to hold the hot nails and melted lines of holes down the length of the pipes. With these hole-ridden pipes, wastewater should flow out over a more evenly distributed area and facilitate more rapid and less concentrated wastewater seepage into the soil.


Instead of small circular pits, Filablenakaw have been digging 4- to 6-meter long trenches which begin about 20 centimeters and eventually expand to a maximum depth of no more than 50 centimeters. We fill them in with rocks in such a way that the plastic pipe is on a gradual incline downwards and wastewater flows all the way down. Then we fill them with more rocks to keep the pipe stable, and cover the end of the pipe with a large flat rock to protect it from closing up.


Eventually we’re going to cover the trenches all up with plastic sheeting and cover them with the dirt that was dug up in the first place so that the sewage is contained underground, people and animals can walk over them without falling in, and every year or so homeowners can open up their infiltration trenches to inspect them and clean them as necessary.

However, there are some negative aspects of this process which make the construction of an infiltration trench an unattractive option. The biggest down point of this technology is that burning holes in the plastic pipes produces noxious fumes and is fairly harmful to anyone who isn’t wearing a respirator – I covered my face with soaking wet handkerchiefs while doing this work, and even then I came down with really bad headaches. Infiltration trenches also require more than 6 times as much plastic piping and sheeting than your average soak pit – but the plastic materials are so cheap compared to the cement that goes into the nyegens that the cost of an infiltration trench cannot be prohibitively expensive to anyone who is building or revamping an entire nyegen. Nevertheless, in communities sitting atop extremely high water tables, infiltration trenches are the most practical, cost-effective technology available for sound wastewater management. It is unlikely that we will be able to completely sanitize Filablena's latrines with such infiltration trenches, but my hope is that the few models which we are building will serve as an example for the entire community to one day safely contain their waste underground and away from the rest of the water supply - insh'allah.

Liquid Gold

One of my investment banker friends wrote to me musing how a poor country like Mali could escape its current stagnation; “Africa will need to diversify its economy away from commodities and raw materials into manufactured products if it has any hope of prospering”, he said, and when it comes to advancing from a subsistence agriculture economy to industrialization, “the bottom line is capital investment.” My friend saw the problem of African poverty in terms of underperforming GDP, a lack of final goods sold at market for currency to be saved in banks to accumulate with compound interest and re-invested so that capital can regenerate and expand unto itself. His view from Manhattan was fairly typical of anyone who makes their living in the trade of credits and debts, who views economic development in terms of developing a monetary economy and a self-contained industry of finance.

However, here in the muddy village of Sanadougou, most economic activity occurs in village without currency ever changing hands. Here the bulk of the population spends most of their labor planting and harvesting millet and rice and corn for their own family’s consumption. When the farming season is done, men spend the next largest chunk of their time building and rebuilding their own homes and granaries with mud and rocks and sticks that they find out in the fields. Women toil day in and day out drawing water and cooking and cleaning and taking care of their many, many children. Gross Domestic Product is such a grossly inadequate means of measuring economic development in this economy, for the food and housing and family networks which make up the bulk of the people’s tangible wealth are never sold as final goods on any marketplace.

The work done by Malian villagers that does count towards the monetary economy is decidedly secondary to food production, house construction and child rearing. In the relatively fertile Sikasso and the southern portions of Ségou, Koulikoro and Kayes provinces, surplus fields are allocated to farming cotton as a cash crop to be sold to the textile mills. In villages like Sanadougou, farmers produce such an excess of peanuts that they can sell them to urban populations who cook tigadegana. During rainy season women also gather shea nuts to cook a butter which is used to make soap and moisturizing cream. And of course all families raise some combination of cows, sheep, goats, chickens, guinea hens or rabbits for meat – only on holidays or weddings could most people ever justify slaughtering an entire goat, so villagers raise livestock mostly to sell to urban butchers. The money these villagers earn in exchange for these cash crops is what pays for their tea, sugar and gasoline. Altogether, the majority of such basic commerce is not transacted between villagers, for it consists of producing raw materials for the consumption of the urban merchant class or for manufacturing into finished goods by multinational corporations.

The most significant cash business in the traditional village economy which stays in the village for local consumption is the tilling of vegetable gardens. Most families have a small plot in their concession fenced in with sticks where they keep a papaya tree, a banana tree or two, and during rainy and cold seasons they can raise an annual patch of onions, tomatoes, lettuce, cabbage, sweet potatoes, yams or manioc. People tend to specialize in one or two crops and sell most of their output from garden season at market, but since tomatoes could never last the 57-kilometer motorcycle ride to the nearest city let alone pay for the cost of the gasoline, perishable produce can only be sold to other villagers. Fruits and vegetables are just about the only cash crops which are consumed in village and therefore insulated from the vicissitudes of global commodity prices and the distortion of First World subsidies. And thus in rural villages the most sustainable economic development takes the form of building gardens and improving their yields. Not only do improved garden yields increase monetary income, but since those yields are consumed in village they increase the population's intake of Vitamin A, Vitamin B, Vitamin C, potassium, phosphorus, etc. An investment in gardens is an investment in economic development and public health.

The World Bank and USAID and NGOs get this quite well. The Western bureaucracies of Third World development love investing in vegetable gardens because not only does it beget economic activity that can be measured by capital-centric indicators like GDP, but building vegetable gardens sounds less like impersonal business and more like good ol’ American humanitarianism.

Unfortunately, the Humanitarian-Industrial Complex understands the value of vegetable gardening only so much as it can be conducted from the confines of their air-conditioned offices in Bamako. If the only tool in in your tool belt is a hammer, then every problem looks like a nail - and at times it seems as though the only tool at their disposal is a big wad of capital that can only be spent on high-tech contractors also based out of the capitol city. So they buy hundreds of thousands of dollars of hardware, pile into SUVs and swoop into villages and construct elaborate irrigation pump systems and build long chain-link fences for the Malians to plant gigantic community gardens.
But they never stay long enough to teach the people how to maintain the pumps – or they try as best as they can in French to a community that speaks only Bambara. So the pumps inevitably fall apart and no one can fix them and the “beneficiaries” of this big agricultural development projects can benefit themselves in no perceivable way other than dismantling the LEED-certified, solar-powered irrigation pumps and selling the parts as scrap metal. The professional vegetable gardening consultants designed their entire plan on the premise of a functioning irrigation pump, so they didn’t bother investing in quaint technologies like wells and pulleys, so even manual irrigation of this gigantic community garden is now impossible. With no irrigation system this vast plot becomes agriculturally useless, so the villagers pull up all the fence posts and use them to make fences around their own private gardens that they can water by hand. And thus the financial largesse of taxpayers and well-minded donors is all but wasted in a gargantuan orgy of cadeau give-aways and outright theft which does little more than enrich the most enterprising of bandits, discredits any future development efforts, and saps the motivation for truly impoverished people to do anything more than sit on their butts watching Akon music videos on their iPhones and wait for the next SUV full of white people handing out presents.

What the Humanitarian-Industrial Complex doesn’t seem to grasp is that if there is ever going to be sustainable economic growth on the village level, it has to be done without massive infusions of Western capital; in fact, if an economic development project requires the investment of foreign capital, it is going to end once the money dries up and is therefore almost certainly unsustainable in the long run. One guy with a cousin who works high up in the national bank might somehow be able to land enough cash to buy a tractor, but mechanized farming equipment is still much too expensive to serve any foreseeable benefit to the masses with no savings, no landed property to secure vast sums of credit and no connections to defy the natural laws of capitalism. The only way that truly sustainable economic growth is going to occur on the village level is if Malians adopt methods of augmenting their own gardens’ yields with technologies so cheap that they are practically if not one hundred percent free, simple technologies that they can assemble themselves, technologies that are literally too small to fail.

Often when I am walking through my village’s filthy, disgusting, sewage-filled streets, I think of how "underdevelopment" is just a fancy way of saying that resources aren’t being utilized adequately. But this isn’t South Africa or the Congo; there aren’t any valuable mineral resources underneath Sanadougou’s meager soils and sandstone. There really isn’t much to be employed here besides sand, dirt, mud, crumbly rocks and sunlight. Hell, this economy is suffering because water is scarce…

I also think of the profound dilemmas of sustainable development while I’m micturating, stircumating and taking bucket baths in my nyegen. I wonder what of economic value there could possibly be here that Malians aren’t already capitalizing upon…

After such profound thinking sessions, one of the first things I see when I exit my nyegen is my soak pit – still purposefully unfinished – and one of my four papaya trees. They have become such fixtures of my everyday life that I don’t really give them much thought. But after a while I started to notice something…

Way back in November of 2008 after the late James Brown I's inspirational urination and my digging of Sanadougou’s first ever soak pit, the adjacent papaya tree wasn’t much to sneeze at. It was a wimpy, pathetic looking thing.



But a year later, after 12 months of my peeing and bathing and washing all my urine away into that soak pit, something breathtaking has occurred – that wimpy-looking papaya has blossomed into the most prolific fruit tree in my entire garden!



It is the most magnificent papaya tree in all of Sanadougou!



It is full with more than 30 football-sized fruits!



When I’m toiling away in my garden, the neighbors walk by and marvel at the papaya tree and wonder how it is that I make it bloom so. They assume that I went to the city and bought sacks of “Tubabu fertilizer”, because it is well-known in this country teeming with livestock manure that white people are known to spend exorbitant amounts of money on imported, factory-produced chemicals to fertilize their gardens.

“Well, I water it just the same as the other papaya trees, and I don’t feed it with any more cow poop than the other papayas. The only difference that could explain this one papaya’s great fruits is the fact that it is planted right next to my soak pit, so all of the sewage from my nyegen just happens to flow underground directly towards the papaya’s tap roots. It must be the economical reuse of my own wastewater that is reaping Allah’s blessings upon my garden!”

“Your papayas are dirty!” some neighbors say “Do not eat them!”

Au contraire, my nyegen-fueled fruit is perfectly safe and perfectly delicious! There are few things more rewarding than slurping the flesh of a juicy ripe papaya and knowing that the fruit which I am eating was fertilized with my very own urine.


Out of all seriousness, the use of human urine as fertilizer is a wonderfully efficient and absolutely cheap means of increasing the yields of most garden crops. Many individuals might have religious scruples about fertilizing food for human consumption with human waste, many more might be repelled by the “yuck” factor because it almost sounds like humans are directly consuming their own sewage and all of the pathogens associated with it. But that’s not the case – only intermediary plants are consuming the valuable nutrients which urine contains, so these nutrients are simply being recycled. When you think about it, there really isn’t any substantive difference between using human waste and the waste of other animals as fertilizer – there are minor variations in the chemical content of the excreta of different species and especially depending on their own food consumption, but excess nitrogen passed through homo sapiens is no different than that passed through a cow or a sheep.

The most significant matter to consider when choosing between fertilizers is the N-P-K ratio: the relative proportions between nitrogen, phosphorus and potassium contained in the mixture. The reason why chicken manure is such a more productive fertilizer than the manure of other farm animals is because chickens don’t separate solid and liquid waste through a urethra and rectum – birds dispose of it all at once in one N-P-K-rich smattering with one multipurpose cloacae. Compared to human feces, human liquid waste is remarkably richer in all three nutrients – especially nitrogen. In different proportions, the urine of all mammals is more nutrient rich than their feces. The only reason why animals feces are used exclusively for traditional fertilizer and not animal urine is that it is very easy to send a boy out with a bucket to collect cow poop days after the cows have grazed over a particular field – though to collect livestock urine would either require training those same cattle to pee in a bucket, or for that boy to wait underneath the bovine nether-regions in anticipation of those valuable showers of gold.

We humans, however, have over millions of years of evolution developed the ability to control our bodily functions with behaviors conducive to avoiding disease and enhancing food supplies. Not just agriculture but also sanitation is one of the hallmarks of an advanced civilization. The Bambara people have on their own initiative pieced together mud and sticks for the basic nyegen technology which contains fecal matter underground and disposes of liquid waste out into the village streets. My introduction of more sanitary concrete platforms and soak pits is a significant improvement of their pre-existing technology in so far as further reducing human exposure to dangerous pathogens; however, unless everyone in Sanadougou plants their gardens directly adjacent to their soak pits, even this sanitary infrastructure is a tremendous waste of valuable nutrients which could be used to improve the yields of their fruits and vegetables.

The next step in improving Minianka society's waste management practices is to promote an appropriate technology which renders human urine into a usable, portable fertilizer that can easily be transported to the nearest garden. Merely walking out to the cabbage patch and taking a whiz doesn’t suffice because undiluted urine is so acidic that it is harmful to most plants, and moreover, peeing all over cabbage significantly reduces its desirability to potential customers at market.

I invested 4,500 CFA (~$9) worth of plastic and rubber sold in Sanadougou’s weekly market and made a simple contraption which changes the whole equation. I took a 20-liter plastic gasoline drum and spent a week cleaning and treating it extensively so that it is so antiseptic that I could store drinking water inside it. I filled the drum with 4 liters of water and marked off the water line so that I could know when it was 1/5 full. Then I took a plastic funnel and fastened it to the drum’s opening with sliced-up motorcycle tire inner tubes. With this, I could now pee into this plastic drum and store it with ease.

However, my urine storage tank was still incomplete. What makes urine fertilizer so effective is its rich nitrogen content, but if urine is exposed to the air then most of the nitrogen will escape in gaseous form. So I took five sturdy plastic bags, placed them inside one another and filled the inner-most bag with water so that they would seal the opening of the funnel.



Now when I have to go #1, I just simply aim for this funnel instead of the ground-level aperture of my nyegen. It is no extra hassle – if anything, it’s more convenient because there is less of a risk of splash-back for those of us men with superb aim. Though do not think that urine fertilizer is a technology limited to those endowed with dexterous urine-aiming devices – numerous phallicly-challenged Peace Corps Volunteers have overcome their disadvantage by peeing into a cup and then pouring the contents down into their urine storage tank up to the 4-liter mark.

Then I fill the urine storage tank almost all the way to the 20-liter mark in order to fully dilute the urine so that its pH is acceptable to the plants in my garden. It is important to let this mixture sit for a good length of time so that the urine and water are evenly distributed. And then I use the nyegen like normal for the next three days until application.

The use of human urine as fertilizer is much less of a health risk than using untreated human feces, which can transmit giardia, dysentery, hookworm, roundworm, etc. if applied directly to garden crops and is therefore quite dangerous to the gardener and as well as those who consume their fruits or vegetable. Pure urine, on the other hand, is so acidic that bacteria cannot live very long in it; it is so sterile that in extreme situations where freshwater is inaccessible humans should drink their own urine. The only disease that one should really worry about transmitting via urine fertilizer is schistosomiasis, and for this reason after reaching the 4-liter mark I let my liquid gold sit for at least two if not three days before application. The logic behind this is that schistosomiasis is a disease transmitted by infected persons urinating in bodies of water where other people are bathing or swimming; if an infected person were to directly apply their urine fertilizer in, say, an extra-large banana furrow, the schistosomiasis cercariae could penetrate the skin of another gardener working in that banana furrow later that day. But if the water-borne parasites do not find another carrier within 48 hours of their initial urination into a body of water, they die. If I wait until the third day until applying, urine fertilizer is perfectly safe.

There must be a structured means of applying urine fertilizer as well. It must be applied directly to the soil as close to the roots as possible so as to avoid potential contamination of the edible fruits and vegetables, and so the acidic urine does not damage the plant itself. Directly after application, each recipient plant should be irrigated extensively to ensure that the nitrogen, phosphorus and potassium percolate down into the soil. One should apply only modest amounts fairly evenly amongst all plants, and to alternate fertilization with many non-fertilized irrigations so as not to overload the soil.

This practice is good for most garden crops; I use it for my papayas, guavas, oranges, lemons, bananas, zucchini and butternut squash – all of which have grown tremendously since I began this practice. Urine fertilizer is especially effective on crops which respond to nitrogen levels such as lettuce and cabbage – though with vegetables which are usually eaten raw in salad one must be particularly careful to not splash any diluted pee on the plant itself. There are only a few crops that should not be applied with urine fertilizer, most obviously nitrogen-fixing plants like beans and peanuts, and also rice because paddies are usually flooded with water and those cultivating it would have to wade through potentially schistosomiasis-carrying urine.

The end result is that gardens fertilized with diluted urine can see dramatic multiplications in output. Finnish agricultural chemists found that tomatoes fed with urine fertilizer saw 4.2 times as much yield as the control samples, and calculated that the urine produced by one average adult in one year contains enough nutrients to increase a cabbage crop by 160 cabbages (141 pounds) more than a cabbage crop fertilized with standard commercial fertilizer. And the intensity of urine fertilization has profound effects as well; all of my papaya trees are fertilized with urine – but the one directly adjacent to my soak pit has such a reliable daily stream of nutrients that it has borne 6 times as many fruit (and much larger fruit) than those that have been only mildly fertilized.

The potential of urine fertilizer to jump-start Mali’s gardens and its stagnant village economy is enormous. If a small gardener here were to multiply their tomato yield 4-fold or their papaya yield 6-fold, if they grow an additional 160 heads of cabbage (141 pounds) in one gardening season, they could augment their family’s nutritional intake accordingly. And if they can’t consume an extra 160 heads of cabbage, well, let’s just say that that’s more cabbage than what is sold in Sanadougou’s market over the course of an entire year. Even if just a handful of gardeners in my village were to take urine fertilization to their own plots, it could significantly expand their yields, increase these farmers’ incomes, maybe even lower the price of fruits and vegetables to such an extent that they could become a more regular addition to Malians’ carbohydrate-based diet and improve the health of this entire malnourished society. And the practice of urine fertilization doesn’t require anyone to take out any loans, it doesn’t require some NGO to swoop in and build some overly complicated contraption – all that it requires is the purchase of $9 worth of plastic and rubber, the construction of a nifty little urine storage tank, and for gardeners to pee in it.

If that's not sustainable development on the organic village level, I don't know what is.
