Creating sustainable water systems will continue to be one of the biggest challenges of the 21st century. Multiple-Use Water Services (MUS) has emerged as a water-provision and management approach that addresses the poverty alleviation potential of water projects. MUS is rooted in the multiple ways in which people have interacted with their local water sources over time, and seeks to overcome the fragmented way in which water is currently managed. This report analyzes the gaps in the MUS approach and evaluates previous efforts at integration in the water sector to identify lessons learned and recommendations for making MUS implementation more robust and sustainable.
