This chapter examines the ways cities are dealing with water issues, both in terms of water supply and quality. Geography plays a critical role in this regard, as some challenges relate to weather and climate—for example, most cities in the US Southwest are challenged by water supply and drought. Many Northeastern cities, however, pay more attention to aging infrastructure and issues around stormwater management. We discovered that few cities explored both challenges. This chapter also considers the trend of green infrastructure as an approach for stormwater management.
