Utilization of solar and wind energy for rural

water supply in Ethiopia

Sanitation Engineer; Franz Hollhuber, Principal Water and Sanitation Engineer, African Development Bank

A

pilot project has been launched in Ethiopia with the

objective of providing experience on the use of solar

and wind energy for water pumping, to demonstrate

how the systems should be best designed and implemented

and to popularise the use of renewable systems within

the sector and the communities. The business of water

and sanitation in Ethiopia is included in the Growth and

Transformation Plan-2, 2016–20, and one of the major strat-

egies to implement water supply solutions is to increase the

use of solar and wind energy technologies.

The project design focused on piloting and promoting the

use of solar (photovoltaic) and wind energy for the purpose

of water supply in the rural areas of Ethiopia, and initiating

development of long term investment in these technologies

under the government’s Universal Access Programme (UAP).

This was on the understanding that acquired know-how and

confidence in solar and wind pumping technology would

ensure an increased and sustained supply of water with a

better economic, environmental and social value than small

to medium sized fossil fuel powered pumping systems.

The African Development Bank’s African Water Facility

supported the pilot programme at a cost of Euro 1.99 million

for the supply and installation of the pumps, comprising

about 70 (40 solar and 30 wind) pumping systems, to be

implemented in four regions within the Rural Water Supply

and Sanitation Programme in Ethiopia, namely: Oromia,

Amhara, SNNPR and Tigraye. Complementarity, implemen-

tation of pipe laying, reservoir construction and maintenance

of public fountains were the responsibility of the government.

Development impact

Whereas it was expected that an estimated 130,000 people

would be served by these water supply schemes, at completion

a total of 67 (49 solar and 18 wind) pumping systems were

contracted and completed in four regions, serving approxi-

mately 120,000 people, 50 per cent of which are women. The

project has shown that solar and wind systems are a valid

solution for pumping water in rural areas of Ethiopia. Solar

systems, now a mature technology, have proven to function

very well. The reported shortcomings were mainly due to a lack

of exact data provided by the woredas (administrative divi-

sions of Ethiopia) on the bore holes at the design stage, such

as depth, static water level, drawdown, yield and water quality.

To ensure sustainable operation of the installed systems in

the pilot project, 49 community members were trained for

the installation, operation and maintenance of the system

and 69 water committees were trained on revenue collection.

Additionally, staff from regional, zonal and woreda offices

participated in theoretical training sessions on solar and

wind systems provided by the supervising consultants under

the contract. The capacity building consisted of two sessions

with 70 participants per session (3 per cent of whom were

women) each running over six days. On-the-job training was

also provided by the project contractors to regional, zonal

and woreda water sector experts during the installation of the

pumping systems, specifically one woreda technician and two

community technicians for each site (40 per cent being women).

There is also increased involvement of the private sector

in water services provision in rural areas. Two local private

firms were contracted to design, deliver and install the solar

and wind pumping systems. The capacity of the local contrac-

tors and their staff has strengthened considerably, given their

involvement in the project implementation and it is expected

that they will be able to operate independently in the sector.

The project created awareness in the broader water sector

and within communities at all levels. Woreda staff confirmed

to the Project Completion Reporting (PCR) mission that

numerous communities had expressed a desire for installing

solar pumping systems following successful operations of the

completed systems located in their immediate neighbourhoods.

A noteworthy multiplier effect resulting from participation of

local firms is the upsurge of different NGOs installing solar-

powered systems in the country through the private sector.

Benefits of the project

•Communities have opened their own small businesses

•Income-generating activities have been created such as growing

crops in the water point areas

•Job opportunities have arisen

•Residents claim to have an improved income

•The government can now consider changing all diesel-driven

pumps to solar and wind pumps where the sites are amenable

•The government has included the use of solar and wind pumps in

the Growth and Transformation Plan-2

•Similar developments have been catalysed

•Other development partners and NGOs are considering the

application of solar and wind energy pumps.
