Abstract: Wastewater treatment is essential for safeguarding public health, protecting ecosystems, and supporting sustainable urban development. This report presents insights from anacademic field visit to the Government Wastewater Treatment Plant (WWTP) at Pollachi, Tamil Nadu. The plant is based on Sequential Batch Reactor (SBR) technology, which provides an efficient and compact solution for secondary treatment of municipal sewage. During the visit, students observed the general layout of the facility, including preliminary units (receiving chamber, screens, grit chambers), secondary biological treatment (SBR reactors, decanters), tertiary treatment (chlorination chambers, contact tanks), and sludge handling units (sludge well, centrifuge building). The plant also houses supporting infrastructure such as laboratory facilities, blower rooms, and landscaped green belts that enhance both aesthetics and environmental protection. The visit provided practical exposure to treatment operations, sludge management, effluent quality monitoring, and safety protocols. It also highlighted the broader significance of WWTPs in ensuring sustainable sanitation, preventing water pollution, and promoting wastewater reuse. This report connects classroom knowledge of environmental engineering with real-world field practice, emphasizing the critical role of wastewater treatment plants in urban infrastructure.
