Integrated Decentralized Wastewater Treatment System (IDWTS) was constructed in Walchand College of Engineering, Sangli (Maharashtra, India) in May 2018 for treatment of domestic wastewater generated from residences and hostels. IDWTS was assessed for its potential to remove COD during May to October, 2018. Anaerobic Baffled Reactor and Hybrid Baffled and Biorack Constructed wetland contributed 20% to 25% each for COD removal. Vertical Flow Constructed Wetland performed relatively better (30%). The overall COD removal was found to be 65% to 75%. IDWTS is a potential alternative to existing on-site treatment systems.
