Solar Pump Repair and Maintenance Project

In 1998 the World Vision NGO financed the installation of a solar pump system in the town of Sanadougou. The aim of this project was very straightforward; in this growing market town of more than 4,000 people where the bulk of the population regularly suffers from giardia, dysentery and worms inadvertently contracted by drinking from unsanitary wells, public health could be drastically improved with access to potable drinking water. World Vision hired Bamako contractors to build a groundwater pump, and two water storage towers to be powered by an array of solar panels. The contractors built a pump-serviced livestock-watering trough in the adjacent vicinity of the complex as well as 7 tap posts strategically-located throughout the town; altogether, there are 17 taps – 3 of the posts have room for 3 individual taps while the 4 other posts have only 2 taps. As promising as this system might have been at the onset, the entire system is now essentially useless due to lack of maintenance and necessary repairs. In response to these pressing needs, the Sanadougou Water Committee has petitioned their Peace Corps Volunteer to help them institute a plan to repair and reorganize the entire system.

The solar panels, the pump and storage towers are perfectly fine, but the entire system as a whole is seriously malfunctioning due to breakages at the livestock watering trough and in a way-station in the metal pipe connecting the water pump to the taps in the Filablena neighborhood. These parts cannot be shut off and flow at the maximum rate at all times.



The ever-flowing watering trough and broken way-station overload the capacity of the entire system, directly exhausting the supply of potable drinking water and often leaving the taps dry. Even when there is water left for human consumption the water pressure is significantly diminished, which allows for rust to develop and diminish water quality. Furthermore, the perpetually-flowing components create vast puddles of standing water which serve as a fertile environment for mosquito breeding. Note that the picture above was taken during dry season on a day when most of the overflow had evaporated in the 105-degrees Fahrenheit heat – during cold and wet season, the puddle of overflow from the livestock-watering trough expands almost all the way to the leafless tree in the center-left of the photograph.

The Water Committee has analyzed these broken parts and they have given them to local plumbers to try to weld them back together, but the plumbers have returned to say that these parts are beyond repair; Peace Corps Assistant Water and Sanitation APCD Adama Bagayoko has analyzed these parts as well and independently concluded that the only course of action is to purchase entirely new components. I apologize that I am unable to find the English translations, but specifically, the parts we need are (in French): une ventousse, un compteur, une vanne, un raccord union, une coude MF, un reducteur, une vanne p26, le clapet vapere. We plan on buying these broken parts from the Bamako suppliers SETRA, and we will hire the local welder Smeila Fané to reassemble the malfunctioning parts and weld them onto the rest of the solar pump system. To our understanding, there is no evidence of malfeasance or negligence for the broken parts – this is merely repair which should be expected in such a large system after 12 years of running and is now long overdue.

However, even if we were to replace the broken components at the livestock-watering trough and the way-station, this solar pump system would still be operating well below capacity and with little benefit for public health; only 3 out of 17 taps are currently operational. The problem with the taps is that they are simply too easy to break; children are used to pumping water with the vertical pump handles with such strenuous work that they have to jump up and down to obtain water, and though the horizontal handles to the tap system can be opened with the flick of a wrist, this is a point which apparently has not been conveyed as children have broken all of the tap handles.



Though the direct cause of this problem was of course the children themselves, this result was inevitable when World Vision built this system with the flimsiest, most fragile handles available. And since these little pieces of metal are now gone, the entire solar pump system is now effectively useless, completely wasting the charitable donations of well-minded humanitarians to the tune of about a million dollars. Well, to be fair, it wasn't a total waste - now for a million dollars the cows of Sanadougou could drink better-quality water than their human masters.



Since the townsfolk of Sanadougou cannot access the potable drinking water provided by the solar water pump, they resort to unsanitary, uncovered wells for their supply of drinking water. These traditional wells – which are really little more than holes in the ground – are home to vibrant populations of worms, snails, amoebas, giardia cysts, and in some cases even frogs and fish. In some locations – particularly during rainy season – these unimproved wells are directly polluted with wastewater and contaminated with human fecal matter. The fact that the people must fall back on such substandard water sources is the prime reason why giardia and dysentery are endemic in this community, and why diarrhea is after malaria the most common preventable cause of infant and child mortality.

Of the 3 taps that are functional, they are functional only because certain individuals have put in their own money to buy their own private taps with locks; one being the tap shared by the Peace Corps Volunteer, the doctor and kindergarten teachers, and the other two are adjacent to mechanic shops where they are used to clean motorcycles with potable drinking water. What differentiates the sites of these taps and the other are the functioning ones are used exclusively by a small number of relatively wealthy people who are both willing to spend money on clean water and also confident that their resources will be used almost exclusively by themselves with few (if any) free-riders. Asides from the tap managed by the Volunteer, the two other functioning taps provide little public health benefits to the population as this potable drinking water is used almost exclusively for cleaning motorcycles. As regrettable as this situation might be, it aptly demonstrates the universality of a saying from the American West, that “water flows uphill towards money”; as the rest of the community pays nothing, they are unable to obtain potable drinking water even from the tap system installed next to their homes at great cost.

When World Vision built the solar pump > tap system a decade ago, the NGO agreed to finance the totality of the initial startup costs only because the Mayor agreed that the citizens of Sanadougou would pay for maintenance and operating costs on a pay-as-you-go basis. However, such payments never happened since the taps were free for all to use and break anonymously; and since no one at le Bureau de la Mairie or the Water Committee could possibly know who was and who was not drawing water from the taps, they could not change anyone; without any accrual of maintenance costs, the system of course degraded into oblivion.

With this history in mind, the Sanadougou Water Committee unanimously resolved to 1) replace the broken taps and 2) begin a payment program so that the Committee will be able to garner revenue to finance inevitable maintenance and repairs in the future. The Committee decided that they cannot do only one of these things, they must do both at the same time. And in this way they will capitalize on the opportunity granted them by the need for repairing the solar pump system to fundamentally overhaul its use under the guidance of the Water Committee.

First of all, we need to get new taps that cannot break so easily. After children broke the last tap next to my house I bought a new tap with a hole through the handle so that it can be locked by the user. By limiting the access to this tap to the holder of the three keys, only I, the doctor and the kindergarten teachers next to me could get access to potable water. However, the doctor and kindergarten teachers were really bad about locking the tap after using it. And even when it was locked, children would come to the tap and try to open it – though they could not access water, they could break the handle in trying. After six months, even this tap deteriorated to the point that it could no longer be used.



A month ago I bought another new tap which can only be opened with a key – though unlike the previous model, the key goes directly into the head itself and there is no external handle at all. In other words, there is really no external part on this tap that can be broken by children. What is more, there is only one key to each tap – which means that responsibility unambiguously falls on him or her to maintain it and that they cannot pass the buck to someone else. This model seems promising enough to serve as a model for refurbishing the remaining 14 taps which are currently useless because their handles have been broken off.



Having showed this new tap to the Water Committee, we agreed that we must pair the repairs of the broken livestock-watering trough and way-station with the replacement of all the broken taps with new lockable taps with keys to ensure that the human population can have a sustainable supply of potable drinking water. As my homologue Sidiki Sogoba jokes, “Otherwise, we would spend a lot of money to help only the cows.” And this is the crux for our plan to reorganize the solar pump > tap system. Part of Sanadougou’s community contribution will be to purchase 17 new lockable taps at 3,000 CFA a piece, and these are going to be paid for neighborhood by neighborhood. Likewise, since each tap comes with exactly one key, the Water Committee is going to decentralize the daily operation and maintenance of each tap neighborhood by neighborhood.

Under our plan, each individual tap will be the responsible of exactly one person to whom the Water Committee and village chief – in consultation with the neighborhood – will assign the sole key. For example, the tap post in the neighborhood of Jigila has room for two taps, so we will assign the key to one to the butigitigi whose shop is directly adjacent to the tap post and the other key to a woman next door. Since water collection is primarily the duty of women in Malian culture, we are going to emphasize the assignment of keys to women whenever possible. Very rarely do men ever draw water, so only in circumstances such as this where there is a man who can in fact be counted on to always be next to the tap will we assign keys to men. The Committee agreed that the key criteria in assigning keys should be individuals’ proximity of their home to the tap, reliability of being at that location at any given time, maturity, ability, responsibility, trustworthiness, and of course their interest in volunteering for such a duty. We also agreed that persons of great importance in this community e.g. the chief of the village, the Mayor, the imam and the pastor should expressly not be assigned keys, for their other duties would make them unreliable to be in the vicinity of the tap at all times.

The kletigi – “holder of a key” – would be a position of great responsibility and great power. They have to be willing to open the water tap for all people at all times, to make sure that children to not play with the taps, and to moreover keep a record of who draws water from that tap and how much. Ultimately, the crux of the position of kletigi will be to collect money from every person in the neighborhood who draws water from that tap. The Water Committee agrees unanimously that we have to establish some sort of a payment system to pay for the maintenance and operational costs of the entire solar pump > tap system so that the next time that a pipe leaks or a tap needs replacement, the Committee will have money on hand to pay for any necessary repairs. In so many words, the Sanadougou Water Committee understands that potable drinking water is a valuable commodity that cannot be procured for free, and thus they have taken it unto themselves to transform this useless, broken-down NGO “cadeau” into a functioning utility that bends to the laws of market economics and finance its maintenance and operating costs through user fees.

The Water Committee still needs to work out how exactly they are going to conduct the payment program. There is one camp in the Committee that argues that people should pay a small price i.e. 5 or 10 CFA for every bucket of water so that payment is perfectly conditional to use; another camp in the Committee argues that such a scheme would be impractical to implement and so water tap subscribers should pay a flat monthly rate. The eventual payment policy will probably allow for users to pay for water either by the bucket or by a flat monthly rate. One area of agreement is that on every market day the Committee should assign one kletigi to man the taps next to the market so that they can draw water and collect money from all of the market vendors and customers who would otherwise consume water as free-riders. Each individual kletigi would be responsible for keeping accounts of how much money they collected from each individual and to forward those user fees to the Treasurer of the Water Committee. Another issue that has yet to be decided is whether the kletigi’s should receive any compensation for their work, for the Committee acknowledges that their duties can be an inconvenience, and I voiced wariness that any individual kletigi might pocket user fees which are meant to pay for maintenance and repairs.

One could pose the question of moral hazard in this situation; e.g. “The NGO built this solar pump system on the premise that the village would provide maintenance indefinitely thereafter – why should a foreign development agency pay for the maintenance costs that the villagers agreed to pay themselves?” I can commiserate with this argument; however, it is overlooking a number of important facts: 1) the Mayor's Office which made this original agreement and the Water Committee that wants to revamp the solar pump system are completely separate entities; 2) the World Vision NGO originally built this entire system with easily-breakable taps completely inappropriate for public infrastructure in an African village; 3) the NGO completely dropped the ball in organizing a payment system; 4) the village has never had any experience repairing or maintaining a running water system before. Not to be paternalistic, but the NGO must have had unreasonably great expectations that the Mayor’s Office could be able to effectively manage this complex system without any background experience and without any guidance, training or even suggestions. From my own experience, I can say that World Vision made an enormous mistake by entrusting this responsibility to the Mayor's Office and not the independent Water Committee, because in a rural village it is the traditional, informal government that actually wields all substantial power over public infrastructure - and the Mayor is really just a figurehead who gets paid to be everybody's friend. And le Bureau de la Mairie in question frankly has no genuine interest in managing the public drinking water system. As the Committee explained to me, it was precisely in the Mayor's best interest to just yes the NGO about instituting a payment system and do nothing once they packed up and left, because whereas presiding over a giant new cadeau and not asking anything of anybody is a boon to re-election (even if it evenually falls apart without maintenance), asking the people to pay for public services with user fees or taxes is decidedly not in the best interest of any self-interested public office-holder. Yes, eventually the Water Committee and le Bureau de la Mairie have to be able to eventually manage this system entirely by themselves – but in the meantime, now that one of the two groups has put forward a proposal to get serious about organizing these waterworks and fix what is broken, I think that it is perfectly reasonable to match their own repairs with $483.72 to rebuild a functioning system requisite for sound management.

Altogether, this project will allow the Sanadougou Water Committee to take the long-neglected solar pump system and overhaul it into a functioning water utility, re-organizing it with respect to market forces to benefit the public good. It will respond to the Committee’s desire to repair and reorganize the waterworks by raising funds through the Peace Corps Partnership to pay for new parts for the broken livestock-watering trough and way-station. The Committee will pay for the transportation of the materials from Bamako to the village of Sanadougou, they will hire a local plumber to assemble the parts and a local blacksmith to weld the necessary pieces together. They Committee will also raise money from the villagers to purchase new, lockable heads for the 14 broken taps. And the Committee will follow up by instituting a payment system – probably monthly for certain subscribers, daily for all others, so that they can gain the necessary revenues to pay for maintenance and operating costs in the future. Even after the initial repairs are complete, we will spend the rest of my service working to strengthen the Committee’s accounting and budgeting skills. And if this works out, the Sanadougou Water Committee should be able to build the capacity to effectively manage the solar pump and tap system indefinitely without any need for further foreign intervention.

Operation Sphincter Plug

If you read any literature from the United Nations, World Health Organization, etc. the most widely-used statistic to measure the development of water sanitation infrastructure is the “percentage of the population with access to clean water.” My village of Sanadougou has one water pump which filters out particulate matter, guinea worm larvae, amoebas and giardia cysts – so according to UN/WHO criteria, 100 percent of Sanadougou’s 4,426 inhabitants have access to clean water. And so now everyone is parasite-free and perfectly healthy and there is nothing left for me to do here.

… Just kidding. The Japanese foreign aid agency which funded the construction of the primary school in town was certainly benevolent and forward-thinking in their construction of a water pump and filter next door. So when elementary school kids are thirsty they can drink clean water, and so can I and the few people whose houses are right next to the filtered water pump. But water is surprisingly heavy, and to draw a bucket of water every time you have to take a drink, cook a meal, clean the dishes, do laundry or water the garden, and carrying 50 pounds of water on your head for any distance is an onerous, tedious task. Asides from the cluster of families whose houses are in the direct vicinity of the school, very few people in Sanadougou ever bother to walk all the way to the pump and back.

I would say that 95 percent of the people in town drink well water. And when I say a well, I don’t mean a raised cement-brick structure with a cover and a pulley. When I talk about a well in Mali, I usually mean a hole dug in the ground with water in the bottom – slightly discolored water which looks like the pond you swam in at summer camp. Most people have their own well in the family compound, which means that it is situated on the dirt floor probably equidistant from the kitchen, the chicken coop and the donkey stable. So when your typical Malian is thirsty, the nearest woman drops a bucket into the hole in the ground, pulls it up and drinks whatever is inside. Sometimes people just crouch down in the nearest mud puddle, cup their hands and slurp up the contents.

Hence even though everyone in Sanadougou technically has “access to clean water” provided by the most state-of-the-art Japanese-built pump, if people prefer to drink from their neighborhood mud puddle, the concept of water sanitation here is really little more than a figment of the imagination of some bureaucrat sitting in an air-conditioned office in Geneva. And likewise, it is not very difficult to understand why diarrhea is after malaria the most lethal cause of infant mortality in this country. Some nights when I can smell the telltale sulfur wafting in the air, if I can gauge the direction from which the wind is blowing I can tell precisely which of my neighbors has giardia – my olfactory hypothesis at this point is approximately 70 percent of the good people of Sanadougou.

Some old, dead white guy once said that “Politics is the art of the possible.” My mission over the next two years is to design and implement an affordable and feasible plan to reduce the number of people in this village suffering from water-borne diseases, and methinks that the most doable stratagem within my reach for reducing the number of children who die from dehydration before their parents carry their tiny bodies to the clinic next door in vain is to concentrate on combating diarrhea. The threat of HIV/AIDS, cancer, tuberculosis, African river blindness, and even Al-Qaeda in the Islamic Maghreb pales in comparison to the threat to Malian well-being posed by diarrhea, and so it is this doer of evil towards which I am for now concentrating my labor. And so I call my current campaign Operation Sphincter Plug.


I am absolutely anal retentive (pun intended) about what I drink, so any drop of water which gets anywhere near my mouth – unless it was previously in a boiling teapot – comes first from the Japanese water pump, then I filter it again with my own personal two-tiered charcoal filter to be doubly protected against undesirable water-borne organisms, and then I treat it with an ample dose of chlorine bleach. If the Republic of Mali could purchase one of these babies at maybe 50 bucks a pop for each and every one of its 11 million concitoyens, then cholera, dysentery, amoebas, giardia and every single malady which leads to juvenile diarrhea and infant mortality would plummet. However, the World Bank’s inflation-paranoid lending policy has commanded that Mali keep government spending to an absolute minimum – thus no such program could conceivably exist so long as their development policy is restricted to the free market orthodoxy of the Washington Consensus.

I could also organize the farmers of Sanadougou to put aside all of the profits from their peanut and cotton harvests from now on, spend none of it on food and medicine and instead put those profits away in one of the local banks which does not give out interest, and pray that maybe 80 years from now there will be enough accumulated enough capital to construct a new water pump in the center of the village. If this plan works, then the World Bank would be very pleased as the invisible hand of capitalism develops without government interference.

Accepting the fact that people are going to drink from their wells until a more convenient source of water appears in their family courtyard, and acknowledging the cruel realities of my financial constraints, the first forward offensive of Operation Sphincter Plug to eradicate juvenile diarrhea in the village of Sanadougou has been rather modest. Since I can't buy everyone their own personal two-tier charcoal water filter, I am endeavoring to replicate the chemical reactions which occur in the bottom tier of my charcoal water filter: chlorine bleach treatment, a method which works against microscopic pathogens but not larger parasites like guinea worm. I am spending most of my time now going door to door and talking to housewives about how they can treat their well water with chlorine bleach available at any every butigi (the Malian equivalent of a bodega).

Though the concept of microscopic pathogens is not widely understood – many people believe in witches and warlocks – there is a Bambara term banakise which means “bad seeds”. Nobody seems to know what these “bad seeds” are or where they come from, but they are undoubtedly very, very bad. Every Malian I talk to accepts that banakise - whether created by nature or by black magic - can cause sickness. I am never going to be able to get people to stop believing in sorcery, but I’m not a missionary and I don’t care if people believe in ghosts or goblins or the Easter Bunny so I’m not even going to try. Without challenging people’s beliefs or skimping on the science, I explain that chlorine bleach kills the banakise. So far people seem to be receptive to the idea, and they are much more receptive to my suggestions in regards to treating water with chlorine bleach than they are to washing their hands with soap.

I am also trying to teach people how to treat their wells each month with a larger amount of bleach, and this is tremendously more difficult as it involves math. In order to treat well water with the appropriate amount of bleach, one must first ascertain the volume of water in the well. As anyone who has ever taken a junior high school geometry class could probably figure out, this entails measuring the diameter of surface, measuring the depth of the water with a rope tied to a rock, and calculating the volume of a cylinder. Using the Bambara words for “depth” – dunya - and “diameter” - fie, one calculates the volume of well water with the formula

V = d x [π ( f2 / 4)].

Some people in town can understand this concept very well; i.e. people who use math on an everyday basis such as the math teacher, the doctor, carpenters. But the majority of people in Mali are illiterate. I don’t mean illiterate as in people who get their news from the graphs in USA Today – I mean illiterate illiterate, as in people who sign their name with an “X” - if they even know how to hold a pencil. Though the schools in Sanadougou are free of charge, many people simply don’t go because their family needs them to herd cattle and till the peanut fields, and therefore illiteracy is simply a fact of life. In a society where the ability to read and do math beyond simple arithmetic is quite rare, to many people the expression: V = d x [π ( f2 / 4)] is absolute gobbledygook. And so I am engaged in the tedious process of doing the calculations for every family's well and writing a table so all that they have to do is measure the depth of the well water.

That's not all. If you think that it might only be difficult to explain the concept of measuring volume in cubic meters, try explaining the concept of what a meter is. Few people besides carpenters even have any means to make a precise measurement - a peanut farmer who makes the equivalent of 400 dollars a year has little reason to invest in a meter stick. So for many families, I have actually made them meter sticks by simply taking a flat board or pole and copying the hashmarks on my own.

At this rate, I will have explained the treatment of well water with chlorine bleach to every household in Sanadougou in one year; if everyone to whom I teach this practical water sanitation method actually employs it, maybe - just maybe - the number of kids in this village who die from diarrhea-induced dehydration will decrease. Now if only I could convince everyone to wash their hands with soap...
