Delhi Battles Floods: ₹622 Crore Plan for Yamuna Wall and Silt Fix
Delhi to build a 4.7-km Yamuna wall and launch biomining projects to prevent flooding and silt buildup in city drains.
In a decisive move to shield the national capital from the recurring nightmare of seasonal flooding, the Delhi government has greenlit a massive Delhi flood control plan worth ₹622 crore. The comprehensive strategy aims to fortify the city's defenses against the rising waters of the Yamuna and resolve the chronic issue of silt accumulation in the city's drainage network.
The approvals were finalized during the 40th meeting of the Flood Control Board, held at the Delhi Secretariat on October 23. The session was presided over by the Irrigation and Flood Control Minister, Parvesh Sahib Singh.
A Concrete Shield: The 4.7-km Yamuna Wall
One of the most critical components of this expenditure is the construction of a reinforced cement concrete (RCC) wall along the banks of the Yamuna. With an allocation of ₹99 crore, the government plans to build a 4.7-km long barrier stretching from the Magazine Road drain to the Old Railway Bridge.
This wall is designed to act as a primary defense mechanism, protecting low-lying residential and commercial areas that are traditionally the first to be submerged when the river's water levels spike during the monsoon season.
Solving the Silt Crisis with Biomining
Beyond the river walls, the city faces a persistent struggle with its drains. Currently, when drains are desilted, the removed material is often left in piles along the roads and banks. This creates a vicious cycle where the next rainfall simply washes the silt back into the drains, rendering the cleaning efforts useless.
To break this cycle, the Flood Control Board has granted in-principle approval for three biomining projects totaling ₹260 crore. These projects will focus on the scientific disposal of silt, with a particular emphasis on the Najafgarh drain and other high-silt conduits.
"Desilting would have little impact if the removed silt continued to return to drains," stated Minister Parvesh Sahib Singh, emphasizing that biomining is the only way to ensure a permanent solution through scientific disposal.
Transforming Drains into Green Spaces
The government's vision extends beyond mere engineering and disaster management. The Board discussed an ambitious plan to rejuvenate the areas surrounding Delhi's drains, drawing inspiration from the Barapullah drain model.
The proposed transformation includes:
- Public Amenities: Construction of walkways and the installation of proper lighting.
- Environmental Upgrades: Creation of green belts and extensive plantations.
- Safety Measures: Installation of protective fencing to make these zones cleaner and safer for citizens.
Minister Parvesh Sahib Singh has issued strict directives to officials to ensure that all approved works are completed within the designated timelines, with regular monitoring to be conducted to track progress.
