2Global 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

4Research 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
servicesdefining 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

5Water 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

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
7Income 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.

8Poverty Impacts Non Financial Benefits
- Health
- Food security and nutrition
- Diversifying livelihoods and reduced
vulnerability - Social equity and empowerment

9Poverty Impacts Key Findings
- 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

18Potential 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
19Study 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 (gt1 billion)
