Rural Water Supply Management and Sustainability : The Case of Adama Area , Ethiopia

Wise utilization of water resources is becoming very important as world faces water crises. The main objective of this study was to investigate the rural water supply systems with case study in Adama area, in central Ethiopia. Both quantitative and qualitative data were collected and analyzed. Four sample water schemes were selected and totally 148 (63 were female) representative households were selected for answering the questionnaires. Key informant interviews and group discussions were also conducted. The study assessed issues such as community participation, water committee empowerment, management and governance of water supply schemes, women participation, functional status of water supply scheme, sanitation and hygiene issues, external support, and monitoring system of water supply schemes. The findings indicated that the community participation in planning and implementation was very good while monitoring mechanism of operation and management as well as community participation on choice of technology was poor. The water schemes were located at reasonable distances i.e. less than 2 km in most cases and the time taken for round trip to fetch water from source was less than or equal to 30 minutes in most cases, however the queuing time was more than an hour. The water supply was inadequate as only about 15% of beneficiaries could get 20 liters of water per day per capita. The water sources were exposed in many cases to human waste, wild life, livestock and uncontrolled flooding. Sanitary practices in the study area were poor as only about 3.4% had ventilated and improved pit latrine and open pit and/or open field defecation were widely practiced.


Introduction
Wise utilization of water resources is becoming very important as world faces water crises which could hold back human development.According to Millennium Development Goal (MDG) summit Report [1], progress on the MDG 7 target "to reduce by half the proportion of people without sustainable access to safe drinking water and basic sanitation by 2015" is presently on pathway.However rural areas in developing countries across the world remain severely underprivileged, with eight out of ten people not having access to safe water supply.As per WHO and UNICEF [2], 87% of the world population could have access to safe drinking water, a progress of 10% within the last two decades.The report also pointed out that about 884 million people worldwide, out of which 37% living in sub-Saharan Africa, still utilize drinking water from unsafe supply spots.Africa is lagging behind the attainment of the MDG as 340 million Africans lack access to safe drinking water [3].The proportion of the African population who had access to safe drinking water accounted for only 60% by 2010, which is about 11% increase compared to the situation in 1990 [2].In Ethiopia, the percentage was about 68.5% by 2010 indicating good efforts made in the sector during the last two decades [4].
As per urban-rural disparities concerning access to safe drinking water, out of the world population who lacked access to safe drinking water, about 84% were living in rural areas [5].Accordingly, urban safe drinking water coverage for Africa was estimated to be 85% (281 million people) while the rural coverage was about 51% (294 million people) by 2008 [6].In this respect, Ethiopia has made an encouraging progress as access to safe drinking water has increased from 35% and 80% in 2005 to 65.8% and 91.5% in 2010 for rural and urban areas respectively [1].
About 84% of Ethiopian populations live in rural areas.For sizable proportion of the rural population, the major sources of drinking water are unprotected springs, ponds, rivers, and hand dug wells which are exposed to contamination caused by human beings, livestock, wildlife and uncontrolled flooding.The safety and quality of drinking water is further in jeopardy as the culture of open defecation has been socially accepted and widely practiced in most of the rural settings and partly in urban areas as well [7].As a result, the prevalence of water borne diseases has increased at alarming rate.As noted by Dessalegn [8], rural safe drinking water supply provision has commenced in Ethiopia during the late 1950s.Since then, efforts have been made to provide safe drinking water for rural areas although there was more focus on urban water supply before two decades.This condition coupled with other factors, has contributed a lot for the low level of safe drinking water supply provisions of the country until quite recently.Access to safe drinking water has been improved from 19% in 1990 [1] to 68.5% by 2010 [4].
The driving force behind the expansion of access to safe drinking water in Ethiopia was attributed to the incidence of drought and famine in the 70s and the 80s.In response to this devastating situation, and adverse effects associated with years of environmental crises, quite a lot of multi-lateral and bilateral international NGOs, donor agencies and indigenous organizations have devoted significant proportion of their fund for the provision of rural safe drinking water supply and vigorously engaged in this endeavors [8].Despite active mobilization of resources by international and local NGOs and the Ethiopian government, the national safe drinking water coverage of the country has not been improved that much especially in the rural areas [9].The main reasons for this very low level of performance in the supply of safe drinking water, and the quandary for not efficiently utilizing the water resources potential of the country towards realizing sustainable water supply, is attributed to lack of articulate and holistic water policy and insufficient investment for safe drinking water supply [10].In addition to this, communities lack capability in managing the water supply schemes.Such problems indicate the need of in depth studies to investigate the rural water supply systems in the country and finding out the strategies to improve the sustainability of the schemes.
The objective of this study was to investigate the rural water supply systems in Adama area of central Ethiopia.The study focused on assessing household water use practices, assessing communities' attitudes towards water safety and benefits of safe water supply, investigating the contributions of community for water source protection and maintenance, and investigating institutional approaches to enhance the sustainability of water supply schemes.This contributes towards the knowledge base for future research and development of water supply systems in the area.Understanding these aspects of rural water supply systems can give an insight into developing a useful strategy that can potentially address water supply system with lasting benefits over time for the intended communities.

Sustainability of Water Supply Schemes
The concept of sustainability has taken its root from the debate on sustainable development during the early 70s.It becomes a concept that is found out to be more "complex and contested" [11].As per the United Nations document entitled "Our Common Future" (1987) "sustainable development is development that meets the needs of the present generations without compromising the ability of future generations to meet their own needs."This being the case, different organizations used their own version of definition to address their intended objective.
Accordingly, various studies conducted pertaining to water supply services have produced definitions concerning sustainability in the context of water supply projects.Most of these definitions capitalize on financing of regular operation and maintenance costs by users, minimal external assistance in the long term, and continued flow of benefits over a long period [12].In this study, the following water supply sustainability definition of Abrams [13] has been adapted: "Sustainability is about whether or not water and sanitation services and good hygiene practices continue to work over time".According to this definition, the achievement of sustainability engrosses the realization of enduring "beneficial" changes in rural water services.In this case, the issue of sustainability is considered further than limiting itself on technical functionality debate; the expression "beneficial" highlights the outcome on the lives of people and it indicates to services other than technology [14].Over years, several conceptual frameworks have been produced to better understand the essence of rural water supply sustainability.Among those developed conceptualization frameworks, the one that has been shared by many researchers has five key dimensions [12,13]: institutional (organizational), social, environmental, technical, and financial.It is well noted that the success of lasting sustainable water supply services is dependent on the interaction of a combination of factors that give due emphasis for community participation, external collaboration and technical support in order to ensure operation and maintenance of the system [12,13].In order to have a close look at the interplay of these factors, the recently developed conceptual framework of sustainable rural water services [15] is presented in Figure 1.
Factors listed above are interdependent, interactive and crucial for achieving sustainable water services with a corresponding behavior changes over time [16].This delicate balance of interacting factors requires the involvement of a number of stakeholders working together.Sustainability will be achieved only if all stakeholders including communities, Non-Governmental Organizations (NGOs), and governmental offices at different levels and the private sector have sufficient capacity and initiative to do their role [17].In this case community members are called for to make informed choices regarding participation in the project, willingness to share project cost and commitment to bear associated contribution.
Full community participation promotes a proactive process in which the beneficiaries influence the development and management of development projects rather than merely receiving a share of project benefits.Community participation creates an enabling environment for sustainability by allowing users, as a group, to select the level of services for which they are willing to pay, to guide key investment and management decisions, and also to make choices and commit resources in support of these choices [18].The kind of technology that cannot serve the best interest of the beneficiary in terms of the quality of installation and cause further problem for maintenance could negatively impact the sustainability of water supply projects.Technology that fits for purpose of the project and chosen by users needs to be in place [16].

The Study Area
Define Adama district is located in Central Ethiopia, in Oromia Region state (see Figure 2).The topography of the district lies within 1500 -2300 m above sea level and is dominated by surging plains that involve extensive ridges all along its western boundaries.Significant proportion of the district is situated in a sub-tropical agroclimatic zone [19].Adama district is one of highly populated districts.According to population and housing census conducted in 2007 by central statistics agency (CSA), the total population of Adama district is 155,321 as of 2007 [20].The urban population accounts for 16.9%, whereas the rural population accounts for 83.1% of the total population.Concerning safe drinking water access of the district, it was reported that the level of coverage for rural area is 24% and coverage for total the population of the district is 69% [19].

Research Design, Sampling Procedures and Method of Data Collection
The  management practices and system of operation.To this effect, the 4 water supply schemes with a total of 15 water distribution points/public water taps were identified as unit of analysis for this research.These water supply schemes are located at 4 sample communities namely, Adullala Hate Aroreti, Bubissa Kussaye, Cheka Dewero and Geldia Galiye (see Figure 2).The four schemes were selected based on type of water sources and operational mechanisms.Adullala Hate Aroreti water supply scheme consists of boreholes operated by diesel generator, while Geldia Galiye water supply scheme consists of boreholes operated by hydropower.Cheka Dewero water supply scheme is gravityflown-pipe water supply services, while Bubissa Kussaye water supply scheme consists of ponds and hand pumps.
The sample size for each community was extracted from list of beneficiaries who can access the water supply points within the range of 1.5 kilometer radius based on the list of water supply schemes inventory of Adama district.Accordingly, 49, 15, 54 and 30 households were selected randomly from Adullala Hate, Bubissa Kussaye, Cheka Dewero and Geldia Galiye communities respectively.These 148 households were used as source of primary data for this study.Respondents are picked systematically so that all beneficiaries of the selected water points are fairly represented.About 50% of the respondents (representing the households) were illiterate.The gender and age distribution of the respondents are presented in Table 1.
Four focus group discussions (FGD) have been conducted, one FGD in each sample community.In each FGD 10 community members (elders, men and women) participated.Participants pertaining to key informant (KI) interview were selected from community members who are in one form or another have participated in mobilizing the community towards the realization of the water supply schemes under study.Accordingly, key informant interviews that involved 4 participants from each of the four sample communities were conducted.
Before starting detailed data collection, some general information pertaining to the socio-economic, demographic and physical characteristics, settlement patterns, and water supply schemes of the communities under study were gathered.This information has been used as a base for planning the field data collection and determining the selection of the sample population.Based on this information, different data collection instruments (survey questionnaires, interview guides and guiding questions for focus group discussions) were prepared and checked through consulting with experts and conducting initial interviews to obtain feedbacks for pre-testing.The feedbacks were analyzed and the necessary adjustment and corrections has been effected on the interview guides, survey questionnaires and guiding questions.These improved data collection instruments were used to conduct the actual data collection.To this effect, household survey that involves sample respondents has been administered and relevant quantitative data was gathered from the field.By employing participatory rural appraisal (PRA) techniques, pertinent qualitative data was gathered from focus group discussions (FGD).Interview sessions with key informants (KI) have been conducted involving community influential's, elders and others who are active in community mobilization.In addition to pre-testing efforts, triangulation method has been used to ensure the quality and reliability of the data.For this, available documents and technical reports were used.The findings are presented and discussed in the following sections.Similarly, the consolidated responses from KI interviews sessions are presented in Table 3.For instance, in three of the schemes the water fee paid by beneficiaries is very sufficient for operation and maintenance (score value = 4) while in one scheme, it is not sufficient (score value = 0) as there is no access to safe drinking water yet (this scheme is not treated, unprotected well and exposed for contamination).Table 3 also points out that community participation in planning and implementation of water supply schemes is very good while collection and control mechanisms of water fee as well as mechanisms of monitoring the operation and management of the schemes are poor.Most of the issues indicated in these two tables (Tables 2 and 3) are also discussed in detail in the following sections.

Access to Safe Drinking Water and Water Use Practices by Communities
In this study, 65% of the total respondents have stated that they use water from improved sources for drinking, cooking and sanitation.About 23% of the respondents have pointed out that women are responsible and sole supplier of water for household requirements.Studies by WHO and UNICEF [2] indicated that families who don't have pipe born water connected to their premises usually assign women in the household to fetch water for house hold consumption.An enhanced access to safe drinking water provides the deprived, especially women, an opportunity to be in command of vital aspects of their livelihood and maximize their sense of confidence/self-esteem [21].Access to safe drinking water and improved sanitation is fundamental and placed at the very center of concerted action towards poverty reduction.
Regarding the travel time taken to collect water from the source 23% of the sample population have responded as less than or equal to 15 minutes while 41% have responded as 16 -30 minutes.Respondents representing 17% of the sample population have mentioned 31 -45 minutes while 14% responded 46 -60 minutes.On aggregate, 64% of the respondents have responded that they spent less than or equal to 30 minutes to fetch water (round trip).In this respect, previous studies [2] indicated that household members who spent more than 30 minutes to collect water usually fail to fulfill the house hold daily water consumption.The time spent due to multiple trips to collect water is so high in economic terms and contributes to lower productivity.According to WHO and UNICEF [2], sizable proportion of the population in many Sub-Saharan Africa countries, devote more than 30 minutes round trip to fetch water from communal collection points, to be used for house hold consumption.In rural Ethiopian context, residents in rural areas travel more than an hour in order to fetch unsafe water from unprotected springs, rivers and other sources.
Regarding the frequency of travel to fetch water from the source, 48% of the total samples have replied that they made two trips a day.Those who have made a single trip per day constitute 21% of the total respondents.Respondents representing 16% made 3 trips per day while the remaining 12% made more than 3 trips a day to fetch water from the source.About 86% of respondents use both human and domestic animal power to transport water (see Figure 3).
Although most of the water supply schemes considered in this study are located at a convenient place and reasonable distance, the average waiting time/queuing is high and the findings indicate that queuing time at the water source is a major issue that takes away the labor force necessary for other productive activities.About 37.8% of the respondents spend up to 30 minutes while 9.5% spend from 31 -45 minutes as queuing time.More than 49% spend more than 45 minutes as queuing time at the water points.
The average house hold water consumption pattern depends on the family size, the level of income, economic activity, the degree of engagement in productive activity and consumption behavior.The household level economic and productive activity determines the amount of water used per day for the different purposes.The findings of this study indicated that 11% of the respondents   use up to 40 liters per day for household cooking, drinking, sanitation and others purposes while 24% consume 41 -60 liters per day.Similarly, about 24% and 26% consume 61 -80 liters and 81 -100 liters per day respectively while 15% consume more than 100 liters of water per day.In Ethiopia, about 20 liters of water per person per day and accessible within a range of 0.5 to 1.0 km from a dwelling place is considered as adequate water supply [22].Any improvement made in safe water access has to be evaluated as per this definition.Taking this definition in to account, Dessalegn [8] has stated that significant proportion of rural households with safe drinking water access will have less chance of securing adequate amount of water that is quite necessary for their wellbeing.Considering the average house hold number (approximately 5) in the study area, only about 15% may get 20 liters of water per day per person.This indicates that the water supply is inadequate, even though the schemes are accessible at reasonable distances.The findings of this study indicated that some of water points are also used for watering livestock.About 23% of the respondents use ponds and/or water taps to water their livestock.

Community Attitude toward Safe Drinking Water, Sanitation and Hygiene
Respondents' perception towards safe drinking water has got an interesting dimension in terms of understanding their level of awareness concerning hygiene related issues.It is also an indication of planning and implementation of hygiene related activities where issues pertaining to water and sanitation are well addressed [23].Some of factors affecting the safety of water in the communities under consideration have been identified in this study.These include contamination by livestock, bird and wildlife, flooding, human feces, and algae development (see Figure 4).Water sources need to be protected and safe guarded from possible agents of contamination.There are possible health hazards which are associated with exposure of the water supply source to human waste, wild life, livestock and flooding [24].The safety and quality of drinking water is further in jeopardy as the culture of open defecation has been socially accepted and widely practiced in most of the Ethiopian rural settings and partly in urban areas as well [7].
The study area under consideration is located in Awash River basin which has got complicated water quality problems that calls for special attention to be given by stakeholders involved in various agro-industrial activities.This is due to the fact that Awash River is highly exposed to pollution caused by untreated waste-water dis- charges from domestic and industrial activities undertaken in Addis Ababa and surrounding areas [25].
As the population in the downstream extensively uses the water from the river for drinking, irrigation and other socio-economic activities, associated public health risks are significant.The occurrence of high fluoride concentration in groundwater in and around the Awash river basin is another public health concern that requires due consideration of development stakeholders in the area [25].The indiscriminate use of different kinds of pesticides by small and large scale irrigation schemes, and chemical discharges from agro-industrial facilities and smallholders have contributed a lot for surface and ground water contamination of the area under investigation.
Responses given by respondents concerning the water safety issues have indicated community members' level of awareness regarding water safety and what need to be done in the future.It was well noted that maximizing the safe drinking water coverage in rural area is highly associated with the reduction of water born disease and improvement of health status leading to increased household productivity.This can be ensured by increasing awareness of household sanitary situation and working towards improving the sanitary facilities at the household level.Attitudinal change and practicing improved method of waste disposal can greatly improve the safety of drinking water and thereby maximize productivity [24].
The study result has revealed that much has to be done with respect to improving the sanitary facilities at the house hold level.This situation need to be reversed as only 3.4% of the respondents use ventilated and improved pit latrine (VIP).About 45% and 9% use traditional pit latrine and pit latrine with slab respectively.The open defecation accounts for 39% respondents indicating that immediate intervention is required.In Ethiopia, about 12% of the total population use improved toilets, 7% use shared toilets, 21% use traditional toilets and the remaining 60% practice open defecation (8% urban and 71% rural) [26].

Community Participation in Water Supply
Scheme Planning and Construction Table 4 presents the responses concerning community participation.About 48% of respondents have confirmed that community leaders and members are initiators of their water projects.About 16% pointed out that NGOs, governmental offices and community members made coordinated effort in initiating and developing the water supply project idea while 12% recognized only NGOs and governmental offices as initiators of the their water project.argue that communities need to be given greater opportunity to manage and decide on issues like water supply projects [27].Community participation enables the beneficiaries to influence the development and management of projects rather than merely receiving a share of project benefits.The shift of emphasis from supply-driven water supply interventions to Demand Responsive Approach (DRA) is due to the fact that the preceding interventions have failed to provide poor communities with sustainable water supplies.In the case of supply-driven interventions, it was found out that beneficiary communities merely take water supply service delivery but failed to play an active role during project implementation and lack a sense of project ownership [28].Demand responsive approach enable the user community to prioritize their needs, initiate project ideas and entrust informed choices, decide on technology type, and location of facilities that best fit their needs including costs and commitment to bear upcoming responsibilities attached to the project [18].

Development practitioners working with communities
Community participation in determining the type of technology to be used for the water supply project is found to be about 16%.NGOs and governmental offices are the major stakeholders who decide on the type of technology that need to be installed for the water supply scheme as identified by 60% of the respondents.About 12% of the respondents have assigned the choice of technology to the responsible governmental offices while 5% confirmed the involvement of community members, NGOs & governmental offices.The participation of beneficiary community in choice of technology should be improved.The kind of technology that cannot serve the best interest of the beneficiary in terms of the quality and durability can cause further problem for maintenance and negatively affects the sustainability of the projects [16].
It also could increase the transparency in project development and management.
The community participation goes to the point of contributing cash and labor during the prime time of project construction.Once the water supply scheme is in place, stated the respondents as well as participants of the focus group discussion, "the degree of community participation diminishes living aside all the responsibilities on the shoulder of the water committee members".The water committee took all the responsibilities ranging from collecting water fee to operation and maintenance of the water supply scheme without adequate backup from the KPA administration as well as the beneficiary communities.In most cases, the water committee has no reporting mechanism to the community but they communicate to district water and energy office.The communities involved in this study participated mainly by providing local materials (wood, stone and sand), labor, cash, by active involvement in community consultation, community mobilization and acting as a focal person in those dealings with other stakeholders (see Table 5).
The kind of community participations indicated above is the widely practiced form of community participation in Ethiopian context.In general, community willingness to contribute their share of capital costs is crucial to community participation because it acts as an indicator of community commitment to the project [28].The Community participation could be influenced by combined factors such as the kind of community for whom the project is initiated, the potential benefits to be generated from the project at the household and community level, and identity of project initiators and stakeholders.

Tariff Collection and Financial Management
According to the information gathered, there is no standard water tariff structure in place in the study area or elsewhere in other rural areas of the Adama district.As per the sample communities, the amount paid for water supplied varies in accordance with the type of technology used for operating the water supply scheme.Those who use boreholes operated by diesel generator pay US$ 0.056 per 50 liters of water while those who use hydropower pay US$ 0.014 per 50 liters.Those using gravity based water supply pay about US$ 0.17 per 50 liters while those using traditional ponds and hand pumps contributes only labor force participating in construction and maintenance.
However, an effective mechanism to administer the water supply tariff in terms of cost sharing practices to cover the ever increasing operation and maintenance cost is crucial for sustained water supply service delivery and benefit over time.This requires a working tariff structure in place that is reasonably framed in order to cope up the ever increasing operation and maintenance cost.The whole issue behind applying appropriate tariff structure is to create a sense of ownership in the community [12] and ensure sustained water supply service over time.
One of the many factors contributing for sustainable rural water supply system is the practice of cost sharing associated with consumers' payment for water service delivered.It was assumed that users should pay as per the water delivered for their house hold consumption.In this respect, the user community is expected to assess the prevailing costs associated with the operation and maintenance of the scheme and thereby revising the existing water service fee as per the ever increasing cost of operation.It is well understood that water users are not in a position to finance the entire replacement costs of their water and sanitation services, it is essential to think about cost sharing as one alternative alongside other new funding mechanism [16].
Table 6 indicates that about 65% of the respondents have practiced cost sharing by paying as per water supplied.There is growing awareness of the respondents concerning the importance of cost sharing paying the water fee on time.They tend to be well aware of the essence of operation and maintenance costs for sustainability of the service.The principle of user pay has been widely practiced in Adama district and the beneficiary communities are willing to pay as per the water supply service delivered.They beneficiaries believe that the fee will be used for covering operation and maintenance cost and building new water scheme.Building new water schemes is required as about 55% of the sample population have stated that the water supplied is not sufficient for the growing population.

Reliability of the Water Supply Schemes
The issue of functionality of the water supply system and seasonal fluctuations is an area that needs to be given greater emphasis.This is due to the fact that Adama district is geographically located in the rift valley area where the rain fall pattern is sporadic with a corresponding effect of very low ground water recharge rate compared to the amount extracted for use.Drilling borehole and exploiting the ground water potential for water supply has been widely practiced so far.For instance the two water supply schemes (Adullala Hate Aroreti & Geldia Galiye) use boreholes of depth between 150 -200 meters.The water supply scheme in Adullala community has served for over 10 years and failed to cover the consumption rate of the ever increasing population.Besides, it has got technical problems related to the capacity of the pump and fuel consumption rate of the diesel generator used for pumping the water.The Geldia Galiye scheme is at good status, as the scheme has the capacity to satisfy the consumers demand at its present status.Cheka Dewero scheme used to depend on gravity flown pipe water extended from capped spring located at adjacent high land area in other district.The users of Cheka Dewero scheme have faced the problem of recurrent pipe line breakage and water shortage.That of Bubissa Kussaye (represents 10 manually operated hand pumps existing in 2 communities) depends on traditionally protected ponds complemented by 5 hand pumps installed at different sites.These hand pumps are partly functioning and in short supply of water during the dry season due to low recharge rate of the ground water (see Table 7).

Institutional Arrangement
If water projects are to be managed efficiently and are to be sustainable, it is important to promote beneficiary participation in the sense that the main stakeholders should be actively involved in the management of water projects [8].According to the responses obtained in this study, the responsible bodies to make major decision regarding issues related to the water supply scheme are the water committee (35% of responses), and the beneficiary community (23%).The remaining responses indicated shared responsibility between government, beneficiary community, water committee, and donor agencies.
What one can derive from this percentage distribution is that a third of the total respondents used to acknowledge the mandate given to the water committee to manage the water supply scheme in terms of operation & maintenance, collecting water fee, and financial record keeping.The significant participation of the beneficiaries in making major decision indicates that they believe that responsibility should not be left for the water committee alone as such major decisions may have far reaching effect on their livelihoods.

Women Participation
Increased access to safe drinking water would mean much for women and their children in terms of health, productivity and income.Therefore, the involvement of women has to be maximized in terms of water supply scheme planning, implementation and management [8].
The participation of women in the management of the community water supply schemes under consideration is significant as confirmed by 85% of the respondents.However, the number of women representatives in each water committee is less and not satisfactory.According to the directive given concerning the formation and composition of the water committees in Oromia region, the number of water committee members for water supply scheme is 7 out of which the women representation constitutes only two members [29].It was widely believed that social, economic and cultural reasons limit the women participation in water committee.

Consumers' Satisfaction
About 83% of the participants in the study under consideration stated that access to safe drinking water has improved health status of family members.Other benefits recognized by beneficiaries include relief of women and children from exhausting work, more time saved for more productive social and domestic activities, improvement of livestock productivity and household income.Figure 5 illustrates some major factors that could nfluence satisfaction of beneficiaries.i Assessment of data concerning fees has revealed that the water fee is expensive for 26%, cheap for 34%, and fair for 34% of the respondents.About 45% of the respondents stated that they have sufficient improved water supply for drinking, cooking, sanitation and other purposes.However, the majority of the respondents (55%) are still complaining about the sufficiency of improved water supply.Due to the insufficiency, low coverage and seasonal fluctuation of water supply system, the majority of the rural population will have a tendency to use unsafe water sources with high risk of being affected by water born diseases.Unsafe water sources and insecure water storage will create favorable condition for contamination and risk of being exposed to water borne diseases.

The Role of Beneficiaries to Sustain Rural Water Supply System
There appears greater interest and commitment of the study communities to maintain the water supply schemes and ensure the sustainability of safe water supply services.Active participation of community in project initiation and management could generate favorable conditions for sustainability of the water schemes.About 85% of the total respondents contributed to the water supply system sustainability by actively participating in one or more activities such as consultation and discussions concerning the management of the water supply scheme, maintenance service; cash contribution and paying water service fee in time.Community participation allows the user community to decide on major management issues, costs, investments, and make choices and commit resources as per these choices [18].

External Support
Once the water committee is formed, the provision of technical training for effective maintenance, operation and management of the scheme need external support in addition to community participation.For this purpose, the involvement of stakeholders that comprise NGOs and GOs is very important [14].About 45% of the sample respondents have disclosed the importance of communi-cation and collaboration with government offices.In general, about 80% of the respondents mentioned the importance of collaboration with one or more of external bodies such as NGOs, GOs, private sectors, education and research institutions.
The major type of supports given from the district and zonal water and energy offices include maintenance, training, technical assistance represent, provision of spare parts, and financial assistance.The findings indicate that the role of government offices and NGOs focus on filling the gap in areas where the beneficiary community lacks the resources and expertise.The respondents also disclosed that the intervention of external agencies in the management of the water supply scheme needs to be according to the best interest and formal request of the beneficiary community.The beneficiaries intend to have greater say in the management of their respective water supply schemes without being coerced by external agencies [8].In the study under consideration, some respondents (21%) stressed the necessity of intervention by GOs and NGOs to ensure the sustainability of their water schemes.

Monitoring and Evaluation
Regarding the management, operation and maintenance of the water supply schemes, the beneficiaries have some sort monitoring system in place.As stated by some respondents, this was a monthly community discussion forum concerning the socio-economic affairs of their respective community where they were given updates regarding the water supply scheme service coverage and operation status.Monitoring at household and community level has to be encouraged as it greatly contributes towards the realization of sustainability.It also creates, for service beneficiaries, an opportunity of being empowered to manipulate their management and performance [16].

Conclusions and Recommendation
This study was initiated with objective of investigating the rural water supply systems with case study in Adama area, in central Ethiopia.Both quantitative and qualitative data were collected and analyzed.Four sample water schemes were selected and totally 148 representative households were selected and interviewed.Four focus group discussions were also conducted to gather information necessary for in-depth analysis.
The study assessed issues such as community participation, water committee empowerment, management and governance of water supply schemes, women participation, and functional status of water supply scheme, sanitation and hygiene issues, external support and monitoring system of water supply schemes.The findings indicated that it is important to promote beneficiary participation that gives them greater opportunity to manage and decide on issues affecting their water supply systems.
The study confirmed that the community members have participated well in initiating the project idea, operation, maintenance and management of their water supply schemes, even though their participation in choice of technology required for the scheme was limited.They participated by providing local materials, labor, cash and ideas during consultative discussions.The water committees are established to manage the water schemes in collaboration with concerned government offices and NGOs to enhance the sustainability of the water supply systems.
The water schemes are located at reasonable distances i.e. less than 2 km in most cases and the time taken for round trip to fetch water from source is known to be less than or equal to 30 minutes in most cases.However, the queuing time is more than one hour in most cases indicating that it is a major issue that takes away the labor force necessary for productive activities.Even though the schemes are accessible at reasonable distances, the water supply is inadequate as only about 15% of beneficiaries may get 20 liters of water per day per person.
The cost sharing for operation and maintenance of the water supply scheme is well practiced promoting the financial sustainability of the water supply schemes.However, there are possible health hazards which are associated with exposure of the water supply source to human waste, wild life, livestock and uncontrolled flooding.The indiscriminate use of different kinds of pesticides by small and large scale irrigation schemes, untreated waste water and chemical discharges from agroindustrial firms and smallholders could contribute a lot for surface and ground water contamination of the area under investigation.The issue of ensuring environmental sustainability is out of reach as this requires broader approach of environmental management strategies.Sanitary practices in the study area are poor as only about 3.4% have ventilated and improved pit latrine.The rest use either pit latrine with slab/open pit and/or open field defecation.
The beneficiaries understand well the importance of collaboration with external agencies such as government and non-government bodies, and private firms for effective planning, implementing and managing the water schemes.
Based on the findings of this study some recommendations can be made:  Providing training for capacity building and refresher training are important in order to scale up the capacity of the water committees to manage the schemes properly.However, the possibility for refresher training is unthinkable in most cases due to the budget constraint at the district level.Therefore, financial and technical support is required not only at community level but at district levels. The study revealed that the supplied safe water by these schemes is insufficient.Therefore new schemes as well as expansion of the existing systems should be planned and implemented. The study finding has revealed that open defecation is widely practiced in the study area.Therefore, coordinated measures should be taken by concerned government and non-government bodies to provide improved sanitary facilities and appropriate trainings at household level, project level, and community level and district level concerning sanitation and hygiene issues, waste management and protecting water schemes from potential contaminators. The present environmental stress in the Awash River basin affects the quality of drinking water in the study area.For this environmental protection measures has to be taken involving governmental agencies, NGOs and the community at large.

4.1. Summary of Major Findings from FGD and KI Interview SessionsTable 2
presents summary of response (consolidated responses) given under each issue of FGD.Ratings 0, 1, 2, 3, 4 represent given consolidated responses consented by each FGD.For each issue discussed by FGD, the score value is given in the last column (scoring column) for each of the four sample communities.For example, for the issue of community participation in planning and implementation of the water supply projects the score values are 4, 4, 3, 4 indicating that the community participation is good (score value = 3) in one sample community and very good (score value = 4) in three sample communities.The results of FGD analysis indicate that the rate of community participation in planning and implementation is very good while monitoring mechanism of operation and management as well as community participation on choice of technology is poor.
