MUS constructed in the Middle Hills of Nepal consisted of piped gravity ow

systems that provided suf cient and clean water for domestic uses and crop growing

in households, improved with drip irrigation systems (SIMI 2009 ). The MUS
systems incorporated intakes, reservoir tanks as well as transmission and distri-
bution networks. As the systems built were small and used water from small spring
sources, soil erosion, landslides and other ecological problems were not encoun-
tered. Before the construction orientation sessions, feasibility studies and eld

surveys took place.
Multiple-use water services linked with micro-irrigation systems constructed in
Nepal proved to be not only successful in meeting both domestic and irrigation
demand, but also cost-effective investments, providing an annual income gain of
$200 per household coming from a $100 initial investment (SIMI 2009 ; Fig. 12 ).

6.3 Tanzania

Multiple-use water services have been introduced in Tanzania by the Integrated
Water, Sanitation and Hygiene (iWASH) programme in 2010. iWASH is a USAID
funded project, implemented by Winrock International, Florida International Uni-
versity, CARE Tanzania and WaterAid Tanzania, to assist people in Tanzania in
improved access to clean water, hygiene and sanitation services (GLOWS 2012 ).
iWASH incorporates the MUS approach to provide sustainable water supply to
rural and small town inhabitants based on actual household and community water
needs. Under this approach, low-cost technologies for multiple uses were devel-
oped, such as locally manufactured rope pumps, rota-sludge drilling and water

filters. Encouraging results showed that through iWASH more than 51,000 people
