Learn how strategic investments in multiple-use water services can benefit over 1 billion people in rural South Asia and sub-Saharan Africa, enhancing sustainability and poverty impacts. This study assesses incremental costs, benefits, and potential opportunity areas for sustainable water service levels.

Global MUS Assessment Study Goal: inform prospective water sector investments assess the potential of multiple-use water services to sustainably meet the water needs of the poor Key Findings: Strategic investments in multiple-use services can cost-effectively maximize poverty impacts of water services while enhancing sustainability Potential clients: over 1 billion people Where: rural South Asia and sub-Saharan Africa How: New domestic multiple use services Upgrading service levels within existing domestic and irrigation systems

Research Goal, Questions, and Methods Methods 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. Develop a framework for multiple use services—defining service levels Assess incremental costs, benefits and poverty impacts Question 1: What are the incremental costs and benefits of multiple-use approaches over single-use approaches? Evaluate the potential market for multiple use water services Question 2: Where do multiple-use approaches apply and who are the main beneficiaries? Identify potential opportunity areas 4
Water Service Levels Defined Highest-level multiple use services most domestic and productive needs Level 4 Intermediate-level multiple use services many domestic and productive needs Level 3 Basic-level multiple use services limited domestic and productive needs Level 2 cc Basic domestic / basic irrigation single use – either domestic and irrigation Level 1 No services Level 0
6 Water Service Levels Required to Support Multiple Uses Increasing water quantity to support productive uses Improving water quality to support domestic uses Making water availability more reliable to support non-irrigation uses Reducing distance between water source and homestead to support productive uses Reducing distance to homestead, improving physical access to canals
Basic level MUS Income Benefits by Service Level: Domestic Average additional per capita annual income benefits The largest incremental gains in income are achieved at the intermediate service level. Highest level MUS $10 Intermediate level MUS $36 $25 For a family of 5, an additional $125-$350/year Basic Domestic No services

Most rural poor have assets necessary to benefit to some extent Improved water services enhances productivity of these assets Communities with higher water service levels have more home gardens, livestock and small-scale enterprises Poverty Impacts: Key Findings Photo credit: IRC
Costs and Benefits: New Domestic Services Basic level MUS Cost BCR Highest level MUS • 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) Intermediate level MUS Cost BCR Cost BCR Basic Domestic Cost BCR No services
Costs and Benefits: Upgrading Services Basic level MUS Highest level MUS Intermediate level MUS Basic Domestic No services
Where: Mapping the potential market for multiple use services Potential Market Disaggregate Populations By Technology/Water Source For Water Service Levels Enabling Conditions nEstimate Populations By Water Service Levels nMap Socio-Economic Characteristics Using Available Data Assess Potential Client Base Size, Location & Characteristics Assess Economic Feasibility of Multiple Use Services Incremental Costs & Benefits By Service Level & Technology Opportunity action areas
Estimated Rural Populations by Water Service Levels: South Asia and sub-Saharan Africa

Potential for Multiple Uses Systems across livelihood zones 44 million households 220 millionpeople 52% of rural population 3.3 billion USD 4% of total water investment potential
Study conclusions • Multiple use services cost more but generate greater income and poverty impacts and offer greater potential for sustainability • Income generation… Above 20 lpcd, each additional lpcd generates $.5-$1 per year of income. • Improving services from 20 to 100 lpcd translates into an additional $200-$400 for household of 5 • The potential market for multiple use approaches is substantial (>1 billion)
