Rich writes about building an incinerator -
Tuesday morning I awoke to the sound of birds calling and cattle lowing. The cattle are grazed by Maasai herders across the stream that is in front of our tent. This is a very pleasant way to wake up, especially if the rest of the day will involve hard manual labor.
Clinic trash is burned in a pit One of the tasks John Sankok felt our team could complete at the Talek clinic was to construct an incinerator to burn the clinic's medical waste. Before I write about building the incinerator, I should educate you about trash pick-up in Kenya: there isn't any, at least for most people. Having your trash hauled away is more expensive than most Kenyans can afford, so they either throw it over the edge of a ravine or burn it. All types of trash is burned, including plastic and glass, usually in a cool, smoldering fire. There is acrid smoke from the burning plastic, and shards of broken glass fill the ashes when they are raked out. The only recycling is in Nairobi, and since most people can't afford trash service, almost nothing is recycled. If you can afford to have your trash hauled away, that just means it is burned in a fire in a poorer part of the city.
There is no trash service in the town of Talek. Trash litters the ground or is burned in one of the two incinerators in town. At the clinic, all of the trash is burned in a pit in the ground at the back of the clinic grounds. Our task was to improve the process somewhat by building a brick incinerator where the trash could be burned.
On our first day of work, not all of the necessary materials had been delivered and the plans were not available. Tuesday morning the fire bricks had arrived overnight and were in a jumbled pile in back of the clinic where the new incinerator was to be built. However, before building up, the first step was to dig down and pour a slab foundation.
Digging the foundation In Webster this would involve excavating with a power shovel to create a foundation below the frost line, then forms would be set up for the slab and cement would be ordered and delivered and poured by a cement truck. That isn't how it's done in Kenya. Mechanization is almost unknown in Kenya. There is a labor surplus, so most people will work for very low wages, which is cheaper than machines to do the work.
The first step for Chuck, Dick, Sarah, and me was to break the sod in an eight-by-eight-foot square using extremely short-handled shovels and pick-axes. After the sod was removed, a hole had to be excavated to a depth of one foot. I now know that the soil of the Maasai Mara is dark, damp, and sticky; we all took turns breaking the soil with the pick-axe and mattock, then shoveling the clumps out of the hole. After the excavation was done, we scoured the clinic plot for Tufa stones, the volcanic rock that is cut and finished to to build almost every building in Kenya is built from, that were leftover from other building projects. These rectangular stones were placed into the hole to make a "rubble foundation."
Chuck mixing concrete In the afternoon Kuria the mason and Josephat the engineer constructed a form around the hole for the slab. Kuria instructed us in the proper technique to mix concrete in a pile of sand and cement on the ground. This involved shoveling and moving large amounts of sand, then mixing in water and cement using the very short-handled shovels.
I asked Kuria if a manual concrete mixer was ever used, and he said it was too expensive; it was cheaper to hire 50 men who could build a house in one day. There is a small building boom in Talek right now, which makes it shockingly apparent how much labor is expended to build anything. The mixed concrete was then shoveled over the rocks and tamped down. Josephat and Kuria screeded the slab smooth to end the day on Tuesday.
We resumed construction the next morning by laying out the locations of the walls and mixing the mortar (more hard labor) that would be used for the walls. Kuria asked Sarah, "Do you want to work?" and started instructing her in how to place bricks and fill the spaces.
Sarah building the walls A woman doing masonry work attracted a large amount of interest in the following days. Over the course of the day on Wednesday, six of the eight courses of bricks for the walls were finished.
On Thursday we completed the remaining wall courses to a height of just under four feet. Kuria had decided that the roof should have a gable, so he and Josephat constructed a form to pour a concrete gabled roof. We mixed more concrete for the roof, lifted it in buckets, and poured it into the form.
By Friday morning, the roof had hardened enough to remove the forms. Kuria instructed Sarah and I in how to build a chimney that stepped in with each course, that we worked on while he "plastered" the roof with a neat edge. After that, our work on the incinerator was finished, because the concrete needs to set for several days before the front and top doors are put into place, and then they must wait 21 days for the concrete to completely cure before the incinerator can be first used.
Sarah and Kuria next to the new incinerator Building the incinerator was very hard work, and it gave all of us a new appreciation for the life of most Kenyans. Most of them work very hard in adverse conditions. No one we worked with wore goggles or dust masks. Items required by law on job sites in the US, such as safety shoes or hard hats, are unknown. One of the most disheartening things I discovered is that tools we take for granted -- screws, power drills, and circular saws -- are not available. Many of the tools and supplies that are available to Kenyans are of very poor quality. One of the Kenyan people's largest impediments to improving their lives is simply that they can not get quality materials to work with. For someone like me with an office job, the blisters I have now will become calluses, and the calluses will soften and disappear, but for the people of Kenya, the hard work goes on.
