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.

Implementations of new water infrastructure projects must overcome several challenges. Many difficulties are faced while introducing new and emerging technologies for water and wastewater treatment. These challenges stem from the irregular availability of (1) financial resources, (2) skilled personnel for planning, design, and operation, and (3) implementation agencies for executing the project works. Challenges are also faced because of inadequate institutional structures and the absence of facilitating government policies. Quite often societal acceptance is not guaranteed. In this chapter, we discuss various challenges one can expect while implementing new water infrastructure and adopting new technologies for water and wastewater treatment. We discuss infrastructure financing, resources required for implementation, and institutional and policy framework. The importance of social acceptance is also stressed.
