Nambul River in Crisis: A Matter of Urgent Concern for Imphal Valley
A call to action has been issued by the 19Ward No 6 United Club of Uripok in Imphal West district, Manipur. On 7 January 2026, the club submitted a memorandum to the Governor, highlighting the urgent need for comprehensive desiltation and rejuvenation of the Nambul River, which is facing severe pollution and siltation.
Neglected River, Threatened Valley
The Nambul River, a vital component of the drainage system and ecological balance of the Imphal Valley, has been subjected to prolonged neglect. Heavy siltation has significantly reduced the river's water-carrying capacity, leading to frequent flooding and waterlogging during the monsoon season.
- Unregulated deforestation in upstream areas has accelerated soil erosion.
- Continuous discharge of untreated sewage, plastic waste, and other solid waste has severely polluted the river.
- Encroachments along the riverbanks and the absence of effective waste management have contributed to public health risks and environmental degradation, including the deterioration of Loktak Lake.
Failed Cleaning Initiatives and the Need for a Holistic Approach
Earlier cleaning initiatives undertaken under various government schemes have failed to achieve lasting results due to fragmented implementation, poor monitoring, and the absence of a scientific and holistic approach.
The club has urged the Governor to initiate comprehensive desiltation of the Nambul River from its source to its confluence using sustainable methods and to formulate a holistic rejuvenation plan addressing sewage treatment, solid waste management, and removal of encroachments.
Community Participation, Transparency, and Accountability
The memorandum also calls for transparent monitoring mechanisms with community participation, public awareness programs, and an independent audit of funds allocated for Nambul River-related projects. Proper demarcation of the river in accordance with the Manipur Flood Plain Zoning Act of 1978, including the construction of retaining walls where necessary, is also demanded.
Strict enforcement of environmental laws is necessary to halt the discharge of untreated sewage and waste into the river. Accountability must be fixed for officials found negligent in addressing the river's condition.
Implications for North East India and Beyond
The Nambul River crisis serves as a stark reminder of the urgent need for sustainable river management practices across North East India and the broader Indian context. Neglected rivers can lead to environmental degradation, public health risks, and economic losses due to flooding and waterlogging.
A Call for Action and Collaboration
The urgent call for the rejuvenation of the Nambul River underscores the need for concerted action and collaboration among various stakeholders, including local communities, government agencies, and non-governmental organizations. By addressing the issues facing the Nambul River, we can strive for a healthier, more sustainable future for the Imphal Valley and beyond.
