An increasing percentage of the world’s population is predicted to be urbanized within a few decades with an increasing number of people living in cities rather than rural areas. Cities are facing the challenges of rapid and unprecedented levels of growth requiring the delivery of adequate utilities (water, wastewater, roads, transit) to people. Meeting the infrastructure requirements of a rapidly increasing population can overcome the capacity of a city to finance new infrastructure while maintaining the existing network of roads water and wastewater facilities, schools and other public facilities and services. Therefore, it is critical to ensure that cities remain sustainable and resilient by fully utilizing the existing infrastructure and reducing the need for planning and delivery of new infrastructure.
