| Summary: | This paper utilizes information from the
2015 Nigeria National Water and Sanitation Survey to
identify the extent, timing, as well as reasons for the
failure of water points. The paper finds that more than 38
percent of all improved water points are nonfunctional. The
results indicate that nearly 27 percent of the water points
are likely to fail in the first year of construction, while
nearly 40 percent are likely to fail in the long run (after
8-10 years). The paper considers the reasons behind these
failures, looking at whether they can or cannot be
controlled. During the first year, a water point's
location -- the political region and underlying hydrogeology
-- has the greatest impact on functionality. Other
factors—specifically, those that can be controlled in the
design, implementation, and operational stages -- also
contribute significantly. As water points age, their
likelihood of failure is best predicted by factors that
cannot be modified, as well as by the technology used. The
paper concludes that, to improve the sustainability of water
points, much can be done at the design, implementation, and
operational stages. Over time, technology upgrades are important. |
