The Ranchi Municipal Corporation (RMC) has made major progress in successfully finishing a critical trial of its state-of-the-art Sewage Treatment Plant (STP), which was built at an expense of Rs 820 crores. This large-scale project’s main goal is to protect Bada Talab from the damaging effects of tainted water that seeps in from city drains. With its enormous 140 million litres per day (MLD) capacity, the STP is set to completely transform the way the city handles wastewater.
During the trial that took place on Monday, engineers from Larsen and Toubro (L&T), the executing agency, and representatives of RMC participated actively. Comprehensive evaluations of the STP’s operation were conducted, looking closely at important parts like screens, grit chambers, clarifiers, aeration tanks, sludge digesters, and disinfection units. By utilising the cutting-edge Sequential Batch Reactor (SBR) technology, the STP outperforms traditional techniques in terms of efficiency and cost-effectiveness.
This project is a crucial component of the Bada Talab Rejuvenation Project, which was initiated in 2018 under the Ministry of Environment, Forests, and Climate Change’s National Lake Conservation Plan (NLCP). The main objective is the complete restoration of the lake, which includes preventing pollution, improving biodiversity, creating recreational areas, and raising public awareness. Desilting, dredging, beautification, landscaping, and the installation of fountains and lights around the lake are all part of the complex project.
By December of this year, the STP is expected to be formally inaugurated by the RMC, and full-scale operations will follow shortly after. The project will have a beneficial effect not only on Bada Talab but also on downstream water bodies like Hatia Dam and Kanke Dam. By adopting comparable actions to protect essential water resources, the RMC hopes to establish a model for other cities in the state and the country.
This significant achievement demonstrates Ranchi’s dedication to environmental conservation and represents a major step towards sustainable urban development. It is anticipated that the STP’s effective execution will strengthen the city’s position as a pioneer in cutting-edge water management techniques.
