The chapter discusses the strategies for improving effective availability of water in terms of quality and quantity in urban areas for sustaining water supplies to meet the growing demands. This is done for different urban typologies defined by a combination of physical characteristics viz. hydrological regime, geological setting terrain conditions, and climate. For this, conventional water supply options such as surface water and groundwater are first explored. But, while doing this, physical feasibility, economic viability, environmental sustainability, and water quality considerations are integrated in the decision-making framework. Besides the conventional systems, the potential of unconventional options to augment the supplies such as storm water management, collection of water from urban roof catchments and desalination of salt water, including saline groundwater, are explored from the point of view of technical feasibility and economic viability.

Keywords:   roof water catchment, reverse osmosis, desalination, physical feasibility, environmental sustainability, economic viability, groundwater, surface water
