Paving the way for pro-poor and sustainable WASH: The role of local innovation
In peri-urban areas, the increasing number of unconnected customers poses additional challenges. Business-as-usual will not address the problems of low coverage, inadequate service levels and poor sustainability of water and sanitation systems. A combination of new technologies with innovative models of service delivery will be needed to close the existing gaps and reduce inequalities. In particular, service providers will need to simultaneously adopt new, informal solutions for unconnected users and more traditional, formal mechanisms to connect more users to the centralized piped infrastructure, through an ambidextrous strategy.
