Sustainable Water Treatment and Management Approaches in the Urban Environments of Developing Countries

In the current scenario, more than half of the population is settled in urban areas, which serve as hubs of development, prosperity, and manufacturing. However, managing water resources in these developing regions poses a significant challengeChallenges in providing hygienic and efficient solutions. The most common challenges faced by developing countriesDeveloping countries include flooding and extreme weather events. This chapter aims to provide a critical assessment of emerging approaches to sustainable water treatment and management. We will discuss various types of membrane science techniques and advanced water treatment technologies within the context of sustainable water treatment. We will highlight the concept of the circular economy, the implementation of Sponge city initiatives, and decentralized solutions as key components of sustainable water management approaches. We will also explore various opinions on these factors and describe why the transformational agenda for sustainable urban water management perspectives has not yet been fully achieved.
