It is postulated that 'multiple use systems' allow efficient and effective supply of water from different sources to communities for its domestic and for its productive purposes and allow effective interaction with providers of water related services. Such multiple use systems would be highly desirable from the perspectives of using scarce water efficiently, promoting gender equity and improving livelihoods. It is therefore necessary to carry out scientific research to verify the statement about this water-innovation. The mode of research must be 'action research'.

The specific form and management of multiple use systems depends on local socio-economic and biophysical factors, as well as on local institutions and legislation. Eleven 'cornerstones' need to be in place to realize a full multiple use system. Since a blue print cannot be made and many parties are involved, 'learning alliances' have to be set up at the local, intermediate and national levels. These learning alliances identify how much of these cornerstones of multiple use systems are still lacking and members work together to create or implement these. Guidelines are needed for setting up learning alliances and for actually implementing systems of multiple water use.
