1 1 Multiple-Use Water Services Mary Renwick, Winrock International GRUBS Planning Workshop Nairobi, Kenya November, 2008

2 2 Multiple-Use Services: Background Photo Credit: Ronald Loeve Photo credit: Ronald Rospigliosi Photo credit: Kande Matungulu Photo credit: Menno Houtstra Photo credit: Charles Batchelor Photo Credit: IRC Home Gardens Livestock Small-scale Enterprises Domestic uses of Irrigation Systems

3 3 Multiple-use services can cost-effectively maximize poverty impacts of investments in water services while enhancing sustainability Potential clients: over 1 billion people Where: rural South Asia and sub-Saharan Africa How: Upgrading service levels within existing domestic and irrigation systems New domestic multiple-use services Key Findings

4 44 Study Goal: to help inform prospective investments in the water sector by assessing the potential of multiple-use water services to sustainably meet the water needs of the poor. Question 1: What are the incremental costs and benefits of multiple-use approaches over single-use approaches? Question 2: Where do multiple-use approaches apply and who are the main beneficiaries? Identify potential opportunity areas Assess incremental costs, benefits and poverty impacts Evaluate the potential market for multiple use water services Develop a framework for multiple use services— defining service levels Methods Research Goal, Questions, and Methods

5 5 Water Service Levels Defined No services Highest-level multiple use services Intermediate-level multiple use services Basic-level multiple use services Basic domestic / basic irrigation c most domestic and productive needs many domestic and productive needs limited domestic and productive needs single use – either domestic and irrigation Level 0 Level 1 Level 2 Level 3 Level 4 Incremental improvements in water service to support domestic and productive uses

6 6 6 Determinants of water service levels DomesticMultiple UseIrrigation Quantity Quality Reliability Distance (physical, social and economic barriers to access) Reducing distance between water source and homestead to support productive uses Reducing distance to homestead, improving physical access to canals Making water availability more reliable to support non-irrigation uses Increasing water quantity to support productive uses Improving water quality to support domestic uses Water Service Levels Required to Support Multiple Uses

7 7 Average additional per capita annual income benefits—gardens, livestock, small-scale enterprises Basic level MUS Intermediate level MUS Highest level MUS $71 $10 The largest incremental gains in income are achieved at the intermediate service level. $61 $25 Basic Domestic No services $36 $25 Income Benefits by Service Level: Domestic For a family of 5, an additional $125-$350/year

9 9 Basic level MUS Intermediate level MUS Highest level MUS $140 Basic Domestic No services 1.3 Cost BCR 3 - 8$56-105 Cost BCR $98 - 116.67 Cost BCR $63 - 91(neg) Costs and Benefits: New Domestic Services Per capita investment costs include software and hardware Benefit-cost ratios include: Full Investment costs Re-current annual costs (O&M, source protection and capital maintenance fund)

10 10 Basic level MUS Intermediate level MUS Highest level MUS Basic Domestic No services Costs and Benefits: Upgrading Services

11 11 Where: Mapping the potential market for multiple use services Incremental Costs & Benefits By Service Level & Technology Assess Economic Feasibility of Multiple Use Services Assess Potential Client Base Size, Location & Characteristics Potential Market Enabling Conditions Disaggregate Populations By Technology/Water Source For Water Service Levels Estimate Populations By Water Service Levels Map Socio-Economic Characteristics Using Available Data Opportunity action areas

12 12 Example: Mapping Market for New Piped Domestic Multiple Use Services Sources: JMP, 2004. CIESIN, 2004.

13 13 Sources: IWMI, GIAM, 2006. CIESIN, 2004. Example: Mapping Market for Upgrading Irrigation Systems to Support Multiple Use Services

14 14 1.New piped multiple use services for currently unserved at the intermediate service level 137 million$56-$1053.4-7.813-30 2.Upgrading existing domestic piped systems to intermediate multiple uses service level 185 million$844.722 3.Boreholes with hand pumps : upgrading services to basic multiple use service level through communal add-ons to support multiple uses 280 million$255.412 4.Upgrading existing household hand- dug wells to the intermediate multiple use service level through well protection and improved lifting devices 74 million$39 - $1023.4-8.69-26 5.Upgrading existing irrigation systems to basic and intermediate service levels: communal add-ons, domestic storage and home water treatment 447 million$10 - $1102.9 - 273-24 Opportunity Action Area Market Capital investment costs (capita) Benefit- cost ratio Repay ment Period (months)

15 15 Summary and Implications for H2.0 Initiative Multiple-use water services cost more but generate greater income and poverty impacts …enhanced sustainability Income generation … new opportunities for financing water services Large potential market (>1 billion) Significant opportunities for leveraging—interest among practitioners, policymakers, donors … knowledge gaps exist

16 16 H2.0 Initiative: Objectives and Outputs Goal: integrate MUS into the h2.0 Initiative to support the design of an improved monitoring approach for the water sector that is responsive to poor communities’ multiple water needs and geared towards results-based reporting on sector performance. Objective 1: Develop an analytical framework Outputs: Analytical framework to guide phase I activities; identification of survey tools and project partners for technical assistance. Objective 2: Provide direct technical assistance to selected project partners Outputs: Project implementing partners are able to use improved metrics to track and analyze MUS and represent communities’ multiple water needs in an accessible, geo-referenced database Objective 3: Lead a MUS knowledge management and dissemination strategy Outputs: Stakeholders are better informed on MUS and able to integrate a MUS perspective into Phase II roll-out activities; h2.0 activities related to MUS are better linked to existing MUS-related activities, galvanizing a broader network of stakeholders to catalyze growth in the knowledge base overtime.
