The Digha and Kankarbagh Sewage Treatment Plant (STP) project in Patna has received a prestigious international award. The International Water Association honored the project with a Silver Award in the 'Exceptional Project Execution and Delivery' category at the Project Innovation Awards-2026 ceremony held in Glasgow, UK.

Operated under the supervision of BUDCO as part of the Namami Gange Mission, this project purifies 150 million liters (MLD) of wastewater daily. Its key features include a hybrid annuity model and an in-house technology for generating green energy from biogas, which reduces both electricity consumption and carbon footprint. Notably, earlier this year, the project also won the 'Wastewater Project of the Year' title at the Global Water Awards. VA Tech Wabag Limited successfully executed this project.

The Digha STP is the largest single STP in the state, covering a large population in western Patna, including Boring Road, Raja Bazar, Pataliputra Colony, Kurji, and Digha. It includes approximately 288 km of sewerage pipeline and an interception-diversion (I&D) network that directs wastewater from major drains directly to the plant.

The Kankarbagh STP has a capacity of 50 MLD and serves a significant residential area of Kankarbagh, Hanuman Nagar, Rajendra Nagar, and Saidpur, which are among Asia's largest colonies. Its network comprises about 150 km of sewer lines and several sewage pumping stations that lift sewage from low-lying and waterlogged areas for treatment at the plant.
