Abstract

This chapter reviews a number of case studies across the different states in India. It includes textile, pharmaceuticals, and paints industry from West Bengal; textile and dye industry in Rajasthan and Tamil Nadu; sugar industry in Maharashtra; pulp and paper industry in northern India; and tannery industry in Uttar Pradesh and Tamil Nadu. From these case studies, we find that different industries have adopted different measures depending on their capacity. These case studies provide further insight regarding the implementation of common effluent treatment plant (CETP) and effluent treatment plant (ETP). The findings from the West Bengal studies reveal that measures to control water pollutants by setting up ETP in five industries have been successful. While the experiences from leather industry in North and South India show similar results where both have used CETP to control water pollution, a typical cluster of pulp and paper industry in Northern India shows the feasibility of ETP compared to that of CETP. In general, the performance of CETPs has been found to be very unsatisfactory largely because of poor operation and maintenance.
