Technological Solutions for Water Sustainability: Challenges and Prospects: Towards a Water-secure India
This book provides an overview of technical sustainable water management in the Global South, mainly in India, and is structured in five sections:
The current status and challenges for sustainable water management in India
New-age materials for water and wastewater treatment
New technologies for water and wastewater treatment
Sensors for water quality monitoring
Urban water management
Section 1 provides the latest information about the status and challenges for sustainable water management in India from the perspective of water quality, industrial and domestic wastewater treatment, urban water infrastructure and policy and governance towards water security. Section 2 discusses new framework solids for water purification, new materials for arsenic and fluoride removal, nanocomposites for water and wastewater treatment and removal of hazardous materials, and toxicity of these materials. Section 3 presents the new technologies developed for water and wastewater treatment; dealing with pulsed power technology, constructed wetlands, nutrient recovery, low-cost filters and pollution abatement using waste derived materials. Section 4 focuses on sensors, including the development of low-cost colorimetric sensors for eutrophying ions, sensors for conductivity and flow parameters, and multi-analyte assessment for water quality. Finally, Section 5 addresses the issues related to urban water infrastructure, sustainable urban drainage and integrated flood and water scarcity management.
This section also discusses virtual water.
The unique feature of this edited volume is its special perspective on emerging economies in the Global South, such as India. It provides information about adaption of technologies, development of new technologies, and management practices which are context driven and region specific. It also deals with economical and easy to use sensors for large-scale monitoring of water quality and water quantity parameters.

It is projected that by 2025, more than 50% of the population in the Global South will be living in urban areas accounting for a population of 3.75 billion. As the resources are limited, expanding cities in the Global South are facing severe crisis with regard to resource depletion, lack of space, equitable access to critical infrastructure, among other problems. Moreover, the existing infrastructure is aged and is in a dilapidated condition, requiring immediate attention. Adequate supply of water is not only important for living, but also from the perspective of hygiene, public health and control of diseases. However, despite the provision of adequate water, the incommensurate mismanagement of wastewater leads to non-hygienic conditions. Thus, provision of water supply infrastructure should necessarily go hand in hand with appropriate collection and management of wastewater. Further, management of rainwater and prevention of urban flooding through appropriate implementation of storm water drainage is crucial. In this chapter, we review the current status of urban water infrastructure in India. The review includes domestic water supply systems, sewerage systems and storm water drainage systems. The challenges that are being faced towards the evolution of water-sensitive urban areas are identified, and the way forward for surmounting those challenges is proposed.
