Rs105-Crore Wadi STP Nears Finish, But Will Ambazari Lake Still Receive Sewage? A ₹105-crore sewerage project aimed at preventing untreated wastewater from the Wadi area from entering Ambazari Lake is nearing completion, offering renewed hope for the restoration of the city’s critically threatened water body. However, experts warn that the project may only address part of the problem, as significant challenges persist beyond the Wadi region. The Wadi Underground Sewerage Scheme, launched in 2023, was initially scheduled to be completed by 2025 but has now progressed to the final stages of its key component: an 11 million liters per day (MLD) Sewage Treatment Plant (STP) utilizing Sequential Batch Reactor (SBR) technology. This facility, once operational, will treat wastewater from Wadi before it enters the Ambazari lake system. A senior official noted that the current sewage generation within Wadi municipal limits is approximately 7.2 MLD, and the STP’s design includes sufficient spare capacity to accommodate future growth. The project encompasses a 62.6-km underground sewer network, 2,107 manholes, and nearly 12,935 household connections. Treated water will meet standards set by the Maharashtra Pollution Control Board (MPCB) and the National Green Tribunal (NGT). However, concerns remain about the broader catchment area of Ambazari Lake, which falls within the Nagpur Municipal Corporation (NMC) limits. Numerous residential layouts, housing societies, and apartment complexes have emerged in the Ambazari catchment area, many of which lack adequate sewerage infrastructure. This has led to the continued discharge of untreated sewage into the lake system, even after the Wadi project becomes operational.#nagpur_municipal_corporation #maharashtra_pollution_control_board #ambazari_lake #national_green_tribunal #wadi_underground_sewerage_scheme
