Centralized Versus Decentralized Wastewater Treatment and Reuse- a Feasibility Study for Nitttr Campus, Chandigarh

Abstract

In recent times we have witnessed the emergence of a water availability crisis due to scarcity and pollution of water resources. One of the major causes of water pollution is the widening gap between wastewater generation and treatment which has necessitated a paradigm shift from centralized to decentralized wastewater treatment and onsite reuse. The manuscript attempts to answer the question whether decentralization can be termed as an effective solution to deal with the limitations of centralized wastewater treatment. The scope of decentralization has been explored by means of a feasibility study of decentralized wastewater treatment and onsite reuse in NITTTR campus, Chandigarh. The feasibility study takes into consideration the guidelines, appropriate technology and potential reuse options associated with the adoption of decentralized wastewater management. The purpose of the feasibility study is to determine the saving in freshwater use that can result. from adoption of decentralized wastewater management and onsite reuse
