To meet the Millennium Development Goals (MDGs) for water supply and sanitation, project planners and service providers and the poor themselves in developing countries will have to overcome a number of barriers that impede the improvement of services for the poor. These Guidance Notes identify a number of institutional, legal, financial, and technical barriers to providing adequate services to the urban poor and propose practical solutions based on the experience of a number of relevant cases. These Notes are aimed primarily at project planners, service providers, and community leaders but provide some suggestions for policymakers. A summary of policy issues is included in the last section. Full paper in PDF format (1.80MB); Number of pages: 76p; Source: Water and Sanitation Program; August 2009
