Rural Water Supply
• For more than two decades ,
various efforts have been done
to increase water supply
coverage and to provide safe
water supplies
• The information of failure or
success from constructed
water supply points could be a
lesson to rain water
management systems
• Give an overview of the
survey results of the
performance of the more than
100 rural water supply point

Methodology
• Formal interview, focal
group discussion and field
observation in 2008, 2010
and 2011
• Descriptive statistics based
on percentages and ratios
• Linear regression model
– For example, per capita water
consumption with household size
and distance from the source
– contributions of cash with number
of alternative water sources,
degree of household participation,
and trust on water use committees
Result
• Functionality of schemes:
about only two thirds were
operational
• Amount of water use per day:
Water use was between 10 and
15 l/day per capita
– an increase of household by one
person decreases significantly the
per capita water consumption by
1.5 l/day
– increase in travel by 1 km to the
water source decreased water use
by 6 l/day per capita
Result
• Alternative sources:
– 70% of the 160
respondents in
Semada had more
than one source
– 65% of the villages
from Study B had
unprotected
alternative source
– A unit increase in the number of
alternative sources decreases
the contribution of cash by 0.25

Result
• Operation and maintenance: In about 60% of the
sites in the region, no cash contribution is
observed
• the contributions were not more than 1 birr except
for sites with borehole
• they are poor which is not taken into account
when systems are planned (Carter, 2009) and
• low participation of beneficiaries in the design
and construction as explained by Deneke et al
(2011).
Result
• WUCs: Water Use Committees (WUCs) were
instituted in many villages for governing water
systems
• Ratio is 5 experts for 200 water supply points
• An increase of the level of trust in WUCs by
one unit significantly increases the cash
contributions by 0.19 ETB per month
• Not effective because local indigenous
institutions missing (Deneke et al., 2011)

Most successful RWS
• The Harbu area which is the water scarce
areas described as semi-arid.
• There are no alternative sources such as
springs and shallow wells.
• System is borehole
• 6 Birr/month
• RWS with multiple use
• 6 HDW, one is constructed for
livestock water
• Fontenina springs-developed
by Water Action that have
strong revenue
• Irrigation user safe-guard the
system
Most successful RWS
Conclusions
• The availability of alternative water sources was
an important factor in the failure of the system
– improving unprotected alternative sources near the
houses
• most cash collected for O & M should be spent
on maintenance rather than operation such as
payment for guard
– Operation payments could be in kind by through
participation of all households
Conclusions
• RWS is relatively successful in community that
local leaders participated in the selection of site,
project scheduling, and important decisions
during construction
• Improving the functioning of the Water User
Committees (WUCs)
– be preferable to use local indigenous institutions as described in
Deneke et al (2011) or local leaders
