'It's rare to find a book which examines these key urban processes. By bringing together researchers to explore the processes through which infrastructure is negotiated and shaped, the book escapes the conventional view of networks as narrowly technical objects. In making these essential services more visible to research and policy worlds Frank Ennis's book makes an important contribution to urban studies'. Professor Simon Guy, University of Newcastle, UK 'This book is a must read for planners and policy analysts concerned with innovative approaches to the provision of urban infrastructure. The case-based compilation is rich with ideas and information about practice on an international basis that will become an important resource for teaching and research.' Professor Lynne B. Sagalyn, Columbia University, USA
