In several recent blog posts (August 17, September 9), we have written about Rojina, about building her a house, and about the ISSB technology used in the construction of bricks. Now, with the roofing, water collection system, and pit latrine in place, the home is ready for many years of service to Rojina and her family. Completion has come just when Rojina’s old home is collapsing due to rain, wind, and termite attacks. This good news would not be possible without the generosity of donors in USA, a one-year grant for the purchase of equipment, an eco-friendly brick maker manufactured by a Ugandan firm, the vision and skill of OCHAN’s building contractor–Alfred Angel, and the labor of local youths training to become house-builders.

In this picture OCHAN’s President, William Boto, inspects Rojina’s new house which he calls a “signature core house”: “core” because rooms can be added on one side as needed for more space when funds allow; “signature” because it is a model that is ecologically sustainable in this area of dwindling forests and increased climate change; it conserves water and addresses sanitation as well. Through use of ISSB technology, described in detail in previous blog posts, no stripped tree limbs anchor the structure or are tethered as a truss for the roof, no trees are fed into ovens to fire-harden mud bricks, no bundles of dried spear grass (now scarce due to demand) are used to thatch the roof. Instead, a foundation is dug and interlocking bricks are laid up to the gable level. Cement and road lime are mixed into the bricks which allow them to harden in a matter of hours. Use of mortar is minimized due to the strength of the bricks’ configuration to interlock both horizontally and vertically. Snakes will no longer find ready access by slithering over the wall of this home, for there is no air space between the wall and the roof, unlike in traditional huts.

The water tank system optimizes rainwater collection in this semi-arid climate through the style of roof that supports gutters on four sides. Rainwater flows into a tank made of two layers of rock slabs to seal water and keep it cool. Total cost of building and installation is $550. This local money-saving innovation by OCHAN’s building contractor, Alfred Angel, beats plastic , corrugated aluminum, and regular brick tanks of comparable size (3,000 liters) at several levels: a) low cost of materials–about 50% price of plastic tanks; b) infinite durability and no risk of puncture, unlike water tanks made of plastic ; c) no rusting or evaporation of water through pores that characterize brick tanks; d) less costly to install , because rock slabs are already made locally thus eliminating transportation from commercial centers 25-225 miles away. Of great practical significance is the fact that a family’s daily water collection chore, which generally falls to young girls in a household, will no longer necessitate her long walk with a jerrycan to a stream or bore hole.

Here, we see Rojina’s granddaughter in her school uniform at the new tank filling her jerrycan to carry just around the corner to the family kitchen before leaving for school. Now she can be regularly on time for class. Further, the family’s health will be protected by the use of clean water as will that of neighbors who may use it. A full tank can last a family of four for up to six months.
The third attribute of OCHAN’s signature core house is a two-door pit latrine with a small room for bathing at one end. It is so placed that Rojina’s family and neighbors will benefit from improved sanitation, the lack of which can cause debilitating diarrheal diseases. An attempt to cut costs by refurbishing an old single pit latrine nearby was unsuccessful as its floor was unstable and crumbling, so the workers sealed it. The cost of digging a new pit, building the walls, and roofing is $811, including labor.
Opac Village is no longer in Lira District due to redistricting. Now in Alebtong, a newly created district the headquarters of which are not far from this home site, the village leaders and OCHAN hope to market this new type of housing to the district. If the youths, trained by OCHAN to build Rojina’s house, are invited to build in the new district, they will be on their way to house-building careers. For our housing project, youth development is one of OCHAN’s strategies to support peaceful resettlement. Another is to continue, as resources become available, to build homes for the most vulnerable households. In this village of extreme poverty, there are few local resources as yet for community development. The clan leaders of Opac have identified 25 households desperate for durable shelter. Such help for the most needy fits OCHAN’s values and mission. With continued support from our donors and readers, we can address two issues: the human right to adequate shelter, and the use of eco-friendly housing to slow desertification due to the massive loss of trees for rebuilding thousands of wood-based traditional huts in post-war resettlement efforts.
