One of the major concerns in urban development is proper wastewater management. In many developing countries, the lack of a comprehensive wastewater management law jeopardizes sustainable urban development. This is true in Indonesia where wastewater management regulations at the local level are inadequate. This publication discusses the basic principles of wastewater management services and is designed to be a guidebook for the development of local urban wastewater management legislation. This guidebook's chapters and sections can be readily transformed into the chapters and articles of a local regulation.
