This article was last comprehensively updated in August 2011, with minor updates in 2012. Despite the comprehensive update, some aspects may be outdated, which is in part because primary data are only available for earlier years. Feel free to update the article where needed.

Access to water supply and sanitation in Ethiopia is amongst the lowest in Sub-Saharan Africa and the entire world. While access has increased substantially with funding from foreign aid, much still remains to be done to achieve the Millennium Development Goal of halving the share of people without access to water and sanitation by 2015, to improve sustainability and to improve service quality.

Some factors inhibiting the achievement of these goals are the limited capacity of water bureaus in the country's nine regions and water desks in the 550 woredas; insufficient cost recovery for proper operation and maintenance; and different policies and procedures used by various donors, notwithstanding the Paris Declaration on Aid Effectiveness.

In 2001 the government adopted a water and sanitation strategy that called for more decentralized decision-making; promoting the involvement of all stakeholders, including the private sector; increasing levels of cost recovery; as well as integrating water supply, sanitation and hygiene promotion activities. Implementation of the policy apparently is uneven.

In 2005 the government announced highly ambitious targets to increase coverage in its Plan for Accelerated Sustained Development and to End Poverty (PASDEP) for 2010. The investment needed to achieve the goal is about US$300 million per year, compared to actual investments of US$39 million in 2001-2002. In 2010 the government presented the equally ambitious Growth and Transformation Plan (GTP) 2011-2015, which aims at increasing drinking water coverage, based on the government's definition, from 68.5% to 98.5%.[2] While donors have committed substantial funds to the sector, effectively spending the money and to ensure the proper operation and maintenance of infrastructure built with these funds remain a challenge.

Water resources and use[edit]

The major river in Ethiopia is the Blue Nile. However, most drinking water in Ethiopia comes from ground water, not rivers.

Ethiopia has 12 river basins with an annual runoff volume of 122 billion m3 of water and an estimated 2.6 - 6.5 billion m3 of ground water potential. This corresponds to an average of 1,575 m3 of physically available water per person per year, a relatively large volume. However, due to large spatial and temporal variations in rainfall and lack of storage, water is often not available where and when needed.[5] Only about 3% of water resources are used, of which only about 11% (0.3% of the total) is used for domestic water supply.[6]

The capital Addis Ababa's main source of drinking water is the Gafsara dam built during the Italian occupation and rehabilitated in 2009. Wells and another dam complement the supply.[7][8]

This diagram shows the variability of rainfall in Ethiopia, here in the case of the capital Addis Abeba.

The city of Dire Dawa is supplied exclusively from groundwater that is highly polluted.[9] The situation is most dramatic in Harar where "a steady decrease of the level of Lake Alemaya has resulted in the complete closure of the treatment plant". Due to supply shortfall, water vendors sell untreated water at extremely high prices.[10] The lake dries up because of local climate change, changes in land use in its basin and increased irrigation of khat, a mild drug that is being grown for local consumption and export.[11] A pipeline is expected to bring water over a distance of 75 km from a well field near Dire Dawa to Harar.[12]

The great majority of the rural community water supply relies on groundwater through shallow wells, deep wells and springs. People who have no access to improved supply usually obtain water from rivers, unprotected springs and hand-dug wells.[5] Rainwater harvesting is also common.

Access[edit]

Access to improved water supply and sanitation, in 7 Sub-Saharan countries, from 1990 until 2008.[1]

According to data from the Joint Monitoring Programme for Water Supply and Sanitation of WHO and UNICEF, which are in turn based on data from various national surveys including the 2005 Ethiopia Demographic and Health Survey (DHS), access to an improved water source and improved sanitation was estimated as follows in 2008:

  • 38% for improved water supply (98% for urban areas and 26% for rural areas)
  • 12% for improved sanitation (29% in urban areas, 8% in rural areas)[1]

According to figures used by the Ministry of Finance and Economic Development for planning purposes, however, access was much higher. In 2010, access to drinking water was estimated at 68.5%: 91.5% in urban areas (within 0.5 km) and 65.8% in rural areas (within 1.5 km).[2] The higher figure for rural areas may be because the distance to an improved water source used in this definition is higher than the distance used by the Demographic and Health Survey.

In 1990 access to improved water supply had been estimated at only 17%, and access to improved sanitation had been estimated at only 4%.[1] There thus has been a significant increase in access for water supply and sanitation, which spans both urban and rural areas. More than 138,000 improved community water points were constructed and rehabilitated from 2008 to 2010.[3]

In communities that lack access to an improved water source, women bear the brunt of the burden of collecting water. For example, according to an article by Tina Rosenberg for National Geographic, in the mountain-top village Foro in the Konso special woreda of southwestern Ethiopia women make three to five round trips per day to fetch dirty water from the Koiro river. Each roundtrip lasts two to three hours and water is carried in "50-pound jerrycans".[13]

Service quality[edit]

Drinking water quality. Drinking water quality in Ethiopia varies. The most comprehensive picture of drinking water quality are the results of a national statistically representative survey of piped water supply, boreholes, protected dug wells and protected springs carried out by the WHO and UNICEF in 2004-2005. It shows that 72% of samples complied with the values for coliform bacteria in the Ethiopian drinking water standard ES 261:2001 and the WHO guidelines for drinking water. In the case of piped water supply by utilities compliance was highest at 88%. Open wells and unprotected springs were not included in the survey. Besides bacterial contamination, natural contamination with fluoride is an issue in the Rift Valley. The results of the survey confirm the results of routine monitoring undertaken in the laboratories of the Regional Water Bureaus and the Regional Health Bureaus. The latter results are archived at the Ethiopian Health and Nutrition Research Institute. Interaction and exchange of information between regional health bureaus and regional water bureaus is poor.[14]

Other aspects of service quality. In 2010, 20 percent of rural water systems were malfunctioning, down from 25% in 2007.[3] About 35 percent of the estimated 30,000 hand pumps in Ethiopia, serving an estimated 2 million people, were non-functioning in the mid-2000s.[15] In piped water systems rationing and service interruptions are frequent.[16] There are no wastewater treatment plants in Ethiopia, so all wastewater collected in sewers is discharged without any treatment to the environment.

Responsibility for water supply and sanitation[edit]

For more details see: Regions of Ethiopia

In order to understand responsibilities in the sector it is necessary to provide a brief overview of local government in Ethiopia. Ethiopia is a federal state consisting of the following subdivisions:

  • nine ethnically based regions or Kililoch with a population between 200,000 and 25 million each;
  • 68 Zones with a population between 100,000 and a few million each;
  • 550 Woredas or districts, with a population between 10,000 and more than 300,000 each;
  • A large number of Kebeles, which constitute the smallest administrative units in Ethiopia.

In addition to the nine regions there are two “chartered cities”, (Addis Ababa and Dire Dawa), where the lower-level administrative units mentioned above do not exist. There is wide disparity in development and institutional capacity between regions and also within regions. The Amhara, Oromia, Tigray regions as well as the small Harari region are relatively developed. About 70% of Ethiopians live in these four regions. The Southern Nations, where about 20% of the population lives, is very heterogenous. In the more pastoralist and remote “emerging” regions Somali, Afar, Gambela and Benishangul-Gumuz, where about 10% of the population lives, capacity tends to be lowest.[16]

Policy and regulation[edit]

There are strong national water supply and sanitation policies and key agencies have clear roles and strategies.[17] National policies are set by the Ministry of Water and Energy (MWE), formerly the Ministry of Water Resources (MWR), for water supply, and by the Ministry of Health for sanitation.

In 2006 the government adopted a Universal Access Plan (UAP) to achieve 98% access for rural water supply and 100% access for urban water supply and sanitation by 2012. Its cost was estimated at US$2.5bn. During the first phase until 2012 the focus is on affordable and appropriate technologies, with the following service standards:

Setting Per capita consumption Service radius
Rural 15 liter/capita/day 1.5 km
Urban 20 liter/capita/day 0.5 km

[18]

In October 2006 a Memorandum of Understanding was signed by the Ministry of Water Resources, the Ministry of Health and the Ministry of the Environment to clearly define the roles and responsibilities of each Ministry in the implementation of the Universal Access Plan.[19] Regional Water Bureaus and Woreda Water Desks are in charge of investment planning, monitoring and technical assistance to service providers. Their capacity to fulfill these tasks is sometimes limited.

Water supply[edit]

Formally the MWE's mandate covers only water resources management and it has no legal mandate concerning drinking water supply. Nevertheless, it is de facto the entity in charge of setting policies for water supply and to channel donor funds in the sector to local government entities. As of 2009, what was then the Ministry of Water Resources had 737 employees in eight departments and 10 "services". One of the eight departments is the Water Supply and Sewerage Department.[20] As of 2011 Alamayehu Tegenu is the Minister of Water and Energy.[21]

In 2001 the government adopted a National Water Strategy prepared by the MWR. The overall strategy includes a water resources strategy, a hydropower development strategy, a water supply and sanitation strategy, and an irrigation strategy.[22]

Concerning water supply and sanitation, the strategy aims at:

  • More decentralized decision-making
  • Promoting the involvement of all stakeholders, including the private sector
  • Increasing levels of cost recovery
  • Integrating water supply, sanitation and hygiene promotion activities.

The strategy document does not include a diagnostic of the current situation. The water and sanitation part of the strategy alone includes 44 recommendations concerning technical, institutional, capacity building, social, economic and environmental issues. There is no priorization between the recommendations and the strategy does not establish mechanisms to monitor the implementation of the strategy.

Sanitation[edit]

The Ministry of Health is in charge of policies related to sanitation and hygiene promotion. It has adopted a Sanitation and Hygiene Promotion Strategy.[23] De facto sewers in urban areas are under the responsibility of the MWR, while the promotion of on-site sanitation is the responsibility of the Ministry of Health. The Sanitation and Hygiene Promotion Strategy has re-focused government resources on the promotion of pro-poor, low-cost practices.[17]

Service provision[edit]

In the capital, the Addis Ababa Water and Sewer Authority provides water and sewer services. In other cities and towns, Town Water Boards are responsible for service provision. They are expected to contract out service provision to private operators. In rural areas community water and sanitation committees operate water systems and promote sanitation. Not all the local committees are registered, which is a prerequisite to open a bank account to hold funds collected from users. Woreda Water Desks (local government entities) are supposed to support local committees. However, according to a research report funded by DFID, the community management service delivery approach that dominates in rural areas in Ethiopia "has bypassed local government authorities and reduced their ownership; however these actors are still needed if rural services are to be sustainable and scalable."[24]

Other[edit]

Regional water resources development bureaus play an important role in planning investments at the regional level and in capacity building.

The Ethiopian Social Rehabilitation and Development Fund (ERSDF) – a Social Fund established in 1996 – is also an important actor, especially in rural areas. It has financed almost 2,000 rural water projects serving about 2.5 million people. However, the government has decided to phase out the ERSDF and to re-deploy its staff to other institutions.[23]

History and recent developments[edit]

Until 1995 the national government had been responsible for centrally planning and implementing water and sanitation projects. Under the 1995 constitution Ethiopia became a federal state, which implied the decentralization of many functions to lower levels of government. This process has now been under way for more than a decade, but decentralization has been hampered by the limited capacity of local government to carry out its new responsibilities.

Also in 1995, a Ministry of Water Resources was created, taking over many of the responsibilities of the water resources department of the former Ministry of Public Works.[23]

In 1999 the government adopted a National Water Resources Management Policy, which was followed by the establishment of a Water Resources Development Fund (2002) and a Water Sector Development Program. The latter includes a water supply and sewerage development program (nota bene the focus on sewerage and thus the absence of on-site sanitation from the program).

The government’s Plan for Accelerated Sustained Development and to End Poverty (PADEP), covering the period 2005-2010, aimed at increasing access to an improved water source to 84% and access to improved sanitation to 80% by 2010. These ambitious targets go well beyond the water and sanitation targets of the Millennium Development Goals, which aim at halving the share of people without access by 2015. According to one set of government figures, which is used by the Ministry of Finance and Economic Development for planning purposes, access to drinking water reached 68.5% in 2010. According to another set of government figures, based on national survey data and used by the WHO and UNICEF to monitor the Millennium Development Goals, in 2008 access to an improved water source was only 38% and to improved sanitation 12%.

In 2010 the government presented the equally ambitious Growth and Transformation Plan (GTP) 2011-2015 that aims at increasing drinking water coverage, based on the government's definition, from 68.5% to 98.5%.[2]

Tariffs and cost recovery[edit]

On average cost recovery is too low to recover operating costs, not to speak of providing adequate maintenance of facilities.[25] Recurrent expenditures – estimated at US$29 million in 2001–02 – were financed primarily through user charges (64%), as well as by subsidies from the regional governments (31%) and the federal government (5%).[26] Despite this overall bleak picture, a few service providers recover all operating costs and generate a modest cash surplus.

The National Water Resources Management Policy aims at full cost recovery for urban systems and recovery of operation and maintenance costs for rural systems. It is not clear if progress has been made to achieve this ambitious objective since the policy was adopted.

Investment and financing[edit]

Investment[edit]

Actual investment. There are no recent reliable estimates of actual investment levels in the sector, and available estimates vary greatly. A detailed estimate of investment and financial flows in the Ethiopian water sector was carried out by the World Bank's Water and Sanitation Program (WSP) for the financial year 2001-02. It estimated total sector investments at US$39 million or less than half a dollar per capita, being one of the lowest recorded sector investment levels in the world.[26] Water and sanitation have declined as a share of total poor-focused expenditure from 7.4% in 2005/06 to 3.4% in 2009/10. In addition, according to research funded by DFID, "actual expenditure may fall well short of these levels. It seems that a very significant proportion of resources are not utilised and are subject to bottlenecks."[24]

Projected investment. The government estimates that annual investments in the 2006-2015 period will reach about US$100 million per year, or about two and a half times their level in 2001-2002. This projection is based on funding commitments made by donors and the government.[19] It thus does not take into account bottlenecks in implementation due to limited capacities or other potential pitfalls. The government estimates that the actual investment needs are about three times as much or US$297 million per year for the period 2006-2015.[19]

Financing[edit]

Sources. According to the WSP estimate quoted, in 2001-2002 only 9% of sector investments were funded by the federal budget, 55% through the regional budget, 33% off-budget by NGOs, 2% by the ERSDF and 1% by other sources.[26] This estimate does not include community in-kind contributions, which are high for rural water supply and sanitation. A high but unknown share of the federal budget and probably also of the Woreda budget devoted to the sector is funded by donors. Concerning projected investments for 2006–2015, it is estimated that 12% (US$12 million) will be funded by the government with its own resources, 15% (US$16 million) by communities and 73% (US$75 million) by donors. It is not clear if this estimate includes off-budget support by NGOs. Because of the different categories used, a comparison between the historical and projected sources of financing is not possible.[19]

Processes. According to a research report funded by DFID, the levels of funding to services delivered by regional and local government are difficult to predict. A large share of donor funding is channeled outside the government budget, although as of 2009 there was a trend for donors and government to "ensure the alignment of financing mechanisms". Where financing is provided through the budget, conditions and reporting procedures are "excessively onerous". Budget transparency and accountability are limited, although efforts are being made to create an open budget system at all levels of government. According to the report the government, particularly at lower tiers, "does not recognise citizens’ rights to information about budget allocations". The Universal Access Plan uses national-level unit costs to allocated government funds to local governments. The unit cost approach fails to take regional differences into account. There is no funding for operation and maintenance or the costs of local governments to support communities in operation and maintenance. This increases the risk that newly built systems will be failing.[24] For the country's 550 Woredas an important source of financing are block grants from the central government which they can use autonomously within broad criteria set by the Water Resources Development Fund (WRDF).[16] The WRDF itself provides loans and is administered by a Board that is responsible to the MWE and is funded through budgetary allocations and donor funds.

External cooperation[edit]

Donors finance numerous projects in water supply and sanitation in Ethiopia – some through the Federal Government and some directly to regions, towns and communities. The donors have established a technical working group (TWG) on water as part of a core donor group called the Development Assistance Group.[27] A Multi-Stakeholder Forum is also supported through the European Union Water Initiative.[17] Despite improved coordination, donors still use different implementation arrangements. As a result, according to the World Bank, transaction cost are high.[16]

Important donors in the sector are the African Development Bank, CIDA, China, the British DFID, the EU, FINIDA, AFD from France, Germany (through GTZ and KfW), JICA, the Netherlands, UNDP, UNICEF and the World Bank. There are also about 500 local and foreign NGOs, many of which are active in water supply and sanitation.[23]

The African Development Bank provided a US$64 million grant for rural water supply and sanitation approved in 2005.[23]

China[edit]

In November 2011 it was announced that China would provide a US$ 100 million loan for water supply in Addis Ababa.[28]

WaterAid[edit]

The British NGO WaterAid is engaged in Ethiopia since 1983. It works closely with established local NGOs. In Oromia Region, water projects tend to be spring-fed gravity schemes, some of which are very large, providing water for tens of thousands of people. In Southern Nations, Nationalities, and People's Region schemes have included deep boreholes as water is sometimes only found below 200 metres.[29] For example, in the village of Orbesho residents - mainly women - built themselves an access road to allow drilling equipment to be brought in, dug trenches for pipes and collected stones for structures.[13] In Amhara and Tigray the main technologies have been hand-dug wells and spring development. In Benishangul-Gumuz rope pumps are also used. In sanitation, WaterAid supports the construction and use of latrines. Hygiene education has increasingly focused on the close links between proper handwashing at critical times, like before eating and after going to the toilet, and improved health. In all cases WaterAid works closely with communities from the start. Particular attention is now being paid to engaging women. Since 1998 WaterAid has also been engaged in the slum areas of Addis Ababa. Projects include establishing communal water points linked to the city's piped systems, as well as shower and latrine blocks.[29]

World Bank[edit]

In May 2012 the World Bank provided approved a USD 150 million soft loan for an urban water and sanitation project as additional financing to a USD 100 million soft loan approved in 2007.[30] The project covers Addis Ababa, Gondar, Hawassa, Jimma, Mekelle and Diredawa. On the sanitation side, it will promote household latrines, hygiene and sanitation practices and constructing communal sanitation facilities. Water production is expected to increase from 50 to 75 liter per capita per day in Addis Ababa and from 30 to 50 liter in the five secondary cities. The water distribution network will be extended to serve 400,000 more people (40,000 connections) in Addis Ababa and 500,000 more people (50,000 connections) in the five secondary cities. The project will also promote awareness of water conservation among customers. The project will also reduce water losses: In Addis Ababa out of the 50 liters per capita per day produced, only 35 reached consumers due to water losses. In the remaining cities only 20 of the 30 liters produced reached consumers.[31]

In March 2010, the World Bank approved additional financing of USD 80 million for a USD 100 million rural water supply and sanitation project approved in 2004. According to the World Bank, until 2010 the original project had financed the construction of 1288 hand dug wells, 835 protected springs, 576 shallow wells, 99 deep wells, 75 rural piped systems and 35 rainwater harvesting, as well as conducting hygiene and sanitation promotion. In rural areas alone, according to the World Bank the project facilitated access to clean water and improved sanitation facilities to about 1.4 million people. In urban areas, the project provided "immediate service improvement" in 87 towns which benefited about 143,000 people.[32][33]
