Defining multiple-use and functions of services
• Multiple-use of water takes place at different levels:– River basin/catchment– “system” / infrastructure– Community– Homestead
• Multiple-use and functions in water services, refers to the explicit catering for these in services provision
![Page 8: Concepts and terminology: an introduction to multiple uses and functions in water services Stef Smits IRC International Water and Sanitation Centre Multiple-Use](https://reader036.vdocuments.site/reader036/viewer/2022081603/56649ec85503460f94bd52f1/html5/thumbnails/8.jpg)
Defining as an approach
• Definition by Van Koppen et al. (2006): a participatory, integrated and poverty-reduction focused approach in poor rural and peri-urban areas, which takes people’s multiple water needs as a starting point for providing integrated services, moving beyond the conventional sectoral barriers of the domestic and productive sectors
• Key elements:– People’s multiple water needs as starting point– Service delivery approach– Integration– Institutional change to move beyond barriers
• Scale and levels
![Page 9: Concepts and terminology: an introduction to multiple uses and functions in water services Stef Smits IRC International Water and Sanitation Centre Multiple-Use](https://reader036.vdocuments.site/reader036/viewer/2022081603/56649ec85503460f94bd52f1/html5/thumbnails/9.jpg)
Objective of mus
• Services to meet people’s multiple needs:– Domestic (drinking, cooking, etc)– Productive: irrigation, livestock, home-based
industries, processing of agricultural products– Functions: flood protection, fisheries,
recreation, etc
• Expectation to contribute to multiple aspects of MDGs

Service delivery approach
• The provision of access to water of a given quality and quantity with given services characteristics – timeliness, flexibility, reliability - at a given place – water ladder
• Through combination of technologies (infrastructure) and service arrangements (financing mechanisms, management arrangements, etc), to climb the ladder
• Not all water needs to come out of one all-encompassing infrastructure: multiple sources for multiple uses

Levels of scale
• Main focus: from homestead to system; catchment normally considered in IWRM
• Often different forms of multiple-use and functions at different nested levels
• E.g. Multiple uses of water at and around homestead provided by different systems, which at the same time fulfil multiple needs and functions at community level
![Page 13: Concepts and terminology: an introduction to multiple uses and functions in water services Stef Smits IRC International Water and Sanitation Centre Multiple-Use](https://reader036.vdocuments.site/reader036/viewer/2022081603/56649ec85503460f94bd52f1/html5/thumbnails/13.jpg)
MUS as a NEW service delivery paradigm for rural areas
• Base philosophy– Effective service provision to reduce rural poverty
• What is the service?– Providing water services that are fitted to rural
peoples lifestyles and livelihoods
• What are the challenges– Understanding livelihoods– Understanding actual – and potential – role of water
within them– Providing appropriate services!

How to achieve paradigm shift
• Planned vs de facto multiple-uses• Domestic-plus, irrigation (productive)-plus, ecosystem
approaches and mus-from-onset• Current institutional arrangements have resulted in
single-use services and sectoral approaches• Institutional change:
– Expanding institutional mandate of sector organisations, starting from each one’s mandate
– Coordination between sectors– Multi-stakeholder approaches
• Entry points are, for scaling-up

In conclusion
• Multiple use and functions of water are obvious; how to cater for them in service provision is the big question
• Requires a service delivery approach from homestead to system level, embedded within IWRM at catchment level
• Paradigm shift, requiring institutional change to come to more integrated services
