DESCRIPTION
Costs and benefits of multiple use water services: a case from Ethiopia. 5 th WWF, Istanbul March 2009. Introduction. RiPPLE is research program funded DFID. It consorium of ODI. IRC, CDS, HCS, WAE - PowerPoint PPT PresentationTRANSCRIPT
Introduction
• RiPPLE is research program funded DFID. It consorium of ODI. IRC, CDS, HCS, WAE
• ECC-SDCOH is the key development partners in Ethiopia involved in a multiple use water service development among diverse programs.
Background• Interventions were focusing to addressing
single use of water• No adequate consideration to sectoral
integration of water with NR, agriculture, livestock, infrastructure, market etc
• Lack of evidence on the costs and benefit as well as the livelihood impact of the single vs multiple uses
Objective: To provide a better insight in the costs and benefits of going up the water service ladder in the developed water schemes in Ethiopia
Multiple use water services

Costs taken into account • Capital investment costs in assets (CapIn), from the implemented and from the community• Operating and minor maintenance expenditure (Opex)• Support costs (SupCo)
Not considered:•“Impact costs”
Benefits taken into account • Health benefits• Time saving benefits• Irrigation benefits• (livestock benefits)

Conclusions
• Introducing single use water services can have impact on the multiple uses of water
• Limited water availability at the source means that different water uses might compete with each other
• Integrated water service delivery for multiple uses is key
• Multiple use services seem to be more cost effective than single use systems (in case of spring systems)
• In case of spring systems, the benefits of going from irrigation services to multiple use services, are high compared to the costs
