Nagpur Municipal Corporation Denies Sewage Contamination in Gorewada Lake
The Nagpur Municipal Corporation (NMC) has firmly rejected escalating allegations of sewage inflow into Gorewada Lake, asserting that the reservoir meets all water quality standards and is not currently utilized for drinking water supply. This declaration follows a comprehensive on-site inspection conducted by municipal officials and water supply committee members.
Official Inspection and Technical Findings
Water supply committee chairperson Divya Dhurde, accompanied by deputy chairperson Vijay Zalke, superintending engineer Shweta Banerjee, and executive engineer Shrikant Waikar, conducted thorough inspections of Gorewada Lake and the Pench I, II, and III water treatment plants on Tuesday. During the examination, officials presented technical data indicating the lake's water quality remains within permissible limits.
Key findings from the inspection include:
- Biochemical oxygen demand (BOD) levels measured at approximately 1.5mg/l, well below the 2mg/l benchmark for clean water
- Complete absence of ammonia, which serves as a direct indicator of sewage contamination
- Chemical oxygen demand (COD) recorded at 15mg/l, significantly lower than the permissible range of 50-250mg/l
- Dissolved oxygen levels around 5mg/l, supporting aquatic life with multiple fish species observed in the lake
- pH level measured at 8.27 and total dissolved solids (TDS) at 198mg/l, both within safe parameters
Technical Report Dismisses Allegations
A comprehensive technical report comparing water quality data from 2019 to 2026 has categorically dismissed recent contamination allegations as "baseless." The report emphasizes that Gorewada Lake currently functions exclusively as an emergency backup source and is not being used for regular drinking water supply to Nagpur residents.
"Visual inspection and available reports indicate that water quality remains within permissible limits," stated Divya Dhurde following the inspection. Fresh water samples were collected in the presence of committee members for detailed physico-chemical analysis to further verify these findings.
Political Controversy and Contradictory Claims
The civic body's assertions emerge amid sharp political criticism and contradictory statements from municipal officials. Congress corporator Shailesh Pandey has alleged that sewage from the Dabha area is being discharged into the lake and claims to have documented NMC drawing water from the same source. These allegations have intensified scrutiny of previous statements made by municipal engineers.
On April 11, superintending engineer Shweta Banerjee acknowledged that NMC does draw water from the lake, while in a March 20 general body meeting, she had previously admitted to sewage inflow while maintaining that no water was being lifted for supply purposes. Opposition members have questioned these apparent contradictions and demanded greater accountability from the civic administration.
Continuous Monitoring and Future Safeguards
Despite the political controversy, NMC officials maintain there is no evidence of contamination in Gorewada Lake. Municipal authorities have emphasized their commitment to continuous monitoring of the reservoir to ensure water safety standards are consistently maintained. The civic body has implemented regular sampling protocols and technical assessments to detect any potential quality issues before they could impact public health.
The ongoing debate highlights the complex challenges municipal authorities face in balancing water resource management, public health concerns, and political accountability in urban environments. As Nagpur continues to develop its water infrastructure, transparent monitoring and clear communication about water quality standards remain critical priorities for both civic officials and concerned citizens.
