New Delhi – Delhi Water Minister Parvesh Verma announced on Wednesday that a cutting-edge Yamuna dredging machine from Finland will arrive in the Capital by December to revolutionize desilting and dredging operations on the Yamuna River and Najafgarh drain. The equipment, identified as a Watermaster Classic IV, represents a significant technological advancement in Delhi’s ongoing efforts to restore water bodies and address persistent flooding challenges. This Yamuna dredging machine investment of ₹8 crore demonstrates the government’s commitment to environmental restoration and flood management.
Sharing a demonstration video on social media, Verma emphasized that the Yamuna dredging machine will augment cleaning efforts and substantially enhance the river’s water-carrying capacity. The minister confirmed that the machine should land in India before December 31 and commence operations from January 1, marking the beginning of a new chapter in Delhi’s water body management strategy.
Advanced Capabilities of the Watermaster Classic IV
The Yamuna dredging machine possesses remarkable versatility as an amphibious multipurpose dredger capable of operating both on land and in water, from dry ground to depths of six meters. This unique amphibious capability eliminates the logistical challenges associated with traditional dredging equipment that requires specialized transportation and setup procedures. The Yamuna dredging machine can perform multiple critical functions including excavation, suction dredging, piling, and raking—effectively replacing the need for several single-purpose machines.
Minister Verma highlighted the dual focus of the initiative: “Cleaning of the Yamuna and Najafgarh drain that was once called the Sahibi river are the two main challenges we face. This machine will arrive in Delhi by December and we will start cleaning both these water bodies soon.”
Technical Specifications and Performance Metrics
The Yamuna dredging machine is powered by a turbocharged six-cylinder Caterpillar C7.1 diesel engine, ensuring robust performance under demanding operational conditions. According to Watermaster’s brochure, the dredger boasts a suction capacity of up to 600 cubic meters per hour and can discharge silt up to 1.5 kilometers away through metal pipes. These specifications make the Yamuna dredging machine exceptionally efficient for large-scale cleaning operations.
The equipment features advanced stabilizers that allow it to anchor independently in water without requiring support vessels, reducing operational complexity and costs. An air-conditioned cabin for the driver enables year-round operation under extreme weather conditions, ensuring continuous progress regardless of Delhi’s challenging seasonal variations.
Innovative Operational Methodology
The Yamuna dredging machine employs a sophisticated cutter and suction system to remove compacted silt, converting it into semi-solid sludge before transferring it away from the cleaning site. This methodology proves particularly effective for addressing the heavy siltation burden affecting Delhi’s water bodies. Additionally, the Yamuna dredging machine can scoop floating waste and features a crane mechanism to assemble its modular parts, providing operational flexibility across diverse cleaning scenarios.

Addressing Dual Challenges: Yamuna and Najafgarh Drain
The 22-kilometer Delhi stretch of the Yamuna between Wazirabad and Okhla remains one of the most degraded sections of the river, burdened by severe siltation and continuous sewage inflow. The Yamuna dredging machine will specifically target this critical section, working to restore the river’s natural flow and ecological health.
Simultaneously, the Najafgarh drain, historically known as the Sahibi river, represents another major challenge requiring the Yamuna dredging machine’s capabilities. Officials explained that the project aims to restore natural water flow, improve flood resilience, and ease pressure on regulator drains throughout Delhi’s water management system.
Environmental Compliance and NGT Approval
With frequent flooding incidents in recent years, the Delhi government plans to approach the National Green Tribunal seeking permission to dredge portions of the river currently restricted to protect aquatic ecosystems. Minister Verma stated, “We are preparing documentation to justify the need and ensure full compliance with environmental norms. Once permission is granted, a detailed project report will follow.”
This cautious approach reflects awareness of environmental sensitivities while addressing urgent flood management needs. Officials noted that similar permissions for selective dredging have been granted for stretches of the Ganga and Brahmaputra rivers in the past, providing precedent for the Yamuna dredging machine deployment.
Expected Impact on Flood Resilience
The Yamuna dredging machine project represents a comprehensive approach to multiple interconnected challenges facing Delhi’s water infrastructure. Officials emphasized that beyond immediate cleaning benefits, the initiative aims to restore the river’s natural flow patterns, dramatically improve flood resilience across vulnerable areas, and significantly ease pressure on the extensive network of regulator drains managing water movement throughout the capital.
Timeline and Implementation Strategy
The confirmed arrival of the Yamuna dredging machine by December 31 and operational commencement from January 1 provides a clear timeline for stakeholders and residents. The ₹8 crore investment demonstrates substantial financial commitment to addressing water body degradation and flood management challenges that have plagued Delhi for years.
The modular design of the Yamuna dredging machine allows for efficient assembly and deployment across different locations, ensuring maximum utilization and flexibility as cleaning operations progress along the Yamuna stretch and Najafgarh drain. This advanced equipment marks a significant technological upgrade in Delhi’s environmental restoration capabilities.
