Well Repair
July 5, July 9
Well repairs have been an integral part of Child Legacy’s mission since the Rogers brought their organization to Malawi in 2008. In its infancy Child Legacy paired with Living Water, a Houston-based organization, to repair the basic afrodare pumps present all throughout the country. Karen Rogers and her sons traveled the country in search of broken or malfunctioning wells. Now Chid Legacy employs a team of five Malawians who have been trained to effectively assess, replace/repair, and document these well repairs. The average cost to repair one well is about $1000 which, along with wages for the well repair team, is funded by donors from the U.S. The well repair was a key part of my initial interest in the CLI placement – I was very impressed that the organization integrates aspects of environmental well-being with health care. Needless to say, I was extremely excited to find out that Sabha and I would be able to join a group of American donors on several well repairs.
The Well Team:
The well team consists of a preacher, a liaison with the village headman, a photographer, a teacher, and a general repairmen. As a Christian organization, the preaching component is critical not only in discussing proper sanitation and hygiene, but also in spreading the Gospel. The team liaison gathers a standard set of information – regarding the village population and the state of the well – which is then compiled for future records. This report includes GPS coordinates, total depth of well, static level, depth of cylinder, time without functioning properly, number of people served by the well (men, women, children), alternative source of water, distance to alternative source, distance to nearest school, and problems encountered with the well. The photographer documents the entire repair to ensure that donors in the US are able to see where their money is going. The teacher’s role on the team is to instruct a responsible member of the community on the well repair process so that they can fix the well themselves should future problems arise. All of the members of the team are trained in the process and aid the general ‘repairman.’ The repair process (simplified version) consists of removing old pipes and rods; measuring the depth of the well and static level; replacing pipes, cap seals, and hanger rods, pouring chlorine as a disinfectant; and replacing the well head, etc.
I learned after the final well repair that there is another critical member of the well repair process – Child Legacy’s development director. This person’s role (at least in the nearby area) is to communicate with local headman to identify which wells are in the most need of repair. They then inform the headman 1-2 days prior to the scheduled repair date. The majority of the repair team was busy in Kasungu (northern) region of Malawi during our stay at CLI, so the repairs that we went on were led by Karen and Sho (the fifth member of the team). While we were unable to see the trained team in action, this did allow for greater participation in the actual repairs and greater interaction with the communities. To give you an idea of how much we slowed down the process – the trained team generally repairs 4 wells a day and we were only able to do 2 per day.
The parts:
Cylinder (pumps the water)
Foot valve (plastic part below cylinder)
Plunger
Rising main (pipe)
Steel rods
Pedestal
Pipe centralizers (stabilize pipe in casing)
Rod centralizers
Rope
Bush bearings
Hanger pin
Fulcrum pin
Handle
Pump head and cover
Bobbin (helps with foot valve and plunger function)
Cap seal (rubber portion around plunger)
O-ring
Other – nuts & bolts, PVC solvent cement, chlorine, cloth, hacksaw, tools (screw driver, etc.)
The Repair:
Sabha and I went on three well repairs (two July 5th and one July 9th) and there was a different root cause for each. In the first village, the rods had rusted and the pipes had been cut so short that they didn’t reach the static water level. The second village had a broken cap seal and the third village had worn bush bearings and worn pipes. Karen informed us that these are very commonly encountered problems. The length of the pipes and hanger rods is very critical. Often the pipes and hanger rods are cut so short that the plunger comes out of the cylinder, bangs on the pipe and wears away at the rubber cap seal. Worn bush bearings can also lead to many, more severe problems from metal hitting metal. When repairing wells themselves, the people often remove the pipes and then reheat instead of gluing the pipes back together. This often causes the centralizers to rub and prevents the rods from working together properly. They always replace plastic plungers with brass and always put in a new cylinder (which should last 5 years if the pump is well maintained).
The Community:
At the first village, I spent the majority of my time talking with the women and playing with the children. One woman gave me a bit of a village tour. She introduced me to her friends, showed me the kitchen where she makes nsima, and brought me to another malfunctioning well nearby. This was my first formal introduction to the full process of making nsima. The maize husks are dried in a straw hut, then the kernels are scraped off and laid out on a mat to dry. Once dry, the grain is pounded into flour and this flour is eventually cooked in pot of boiling water. The most astonishing thing to me was the lack of ventilation in her kitchen, which was a just a small brick room (separate from the living space) with a couple of pieces of wood and some old husks for fuel. She bent down over the fire and blew on the coals to get the fire going, all the while inhaling the smoke pouring out of the fire.
At the second and third villages I got the chance to participate a bit more in the well repair process. While the cause of malfunction may be different from well to well, it appeared that the repair process was pretty standardized – PVC pipes, rods, centralizers, bush bearings, and cylinders were almost always replaced. For me, the most memorable part of the well repairs occurred at the third village. The women and children all began singing and dancing as the repair came to a close. When I asked Lester (who served as the stand-in preacher) what they were singing about he told me that it was traditionally sung at wedding ceremonies as a way of welcoming new members to their family.
