Chapter 6 - Circular economy from a water and wastewater management perspective

Abstract

Urban water security has led to wastewater reclamation in many world areas. Water extraction from sewerage and wastewater has emerged due to the increasing need for clean water resources. Therefore, the community-based reclaimed water (RW) (CBRW) initiatives have become options to overcome this problem. This chapter investigates the current performance and impact of CBRW under the sustainability frameworks. The CBRW is also reviewed based on its contribution to the circularity of the local economy. The input and output water quality are examined to see the impact on the environment. Some technological considerations that can impact the implementation of decentralized wastewater treatment plants are evaluated comprehensively. The socioeconomic dimensions that affect the acceptance of RW are also discussed. A brief overview of the community-based water recycling system will be essential for filling the urban water and wastewater management system gap.
