Delhi government officials plan to redesign the Kalindi Kunj barrage to reduce the recurring froth appearing on the Yamuna River [1, 2].
The initiative seeks to address severe water pollution in southeast Delhi that affects both the river's ecosystem and the aesthetics of the riverfront. The presence of foam on the water surface has become a recurring environmental concern for the city.
Officials are implementing a four-layer plan to curb the pollution [3]. This strategy includes redesigning the barrage and relocating dhobi ghats to prevent detergents from entering the water [1, 2, 3]. Additionally, the government intends to enforce stricter regulations on dyeing units to stop the discharge of untreated effluents into the river [1, 2, 3].
There is a disagreement regarding the primary cause of the froth. Activists said the pollution is caused by a fusion of untreated dyes from illegal dyeing units [4]. However, Water Minister Parvesh Verma said the froth is caused by structural and flow turbulence at the Okhla barrage [5]. This turbulence contributes to the aeration of pollutants, creating the foam.
Reports on the appearance of the pollution also vary. Some sources described the froth as white [1], while activists reported seeing pink froth on the water's surface [4].
As part of the broader riverfront development, the government plans to construct a new Chhath Ghat near the barrage [1, 2]. The estimated cost for the construction of this site is ₹100 crore [2].
The redesign of the Kalindi Kunj barrage is intended to stabilize water flow and reduce the turbulence that traps pollutants. By combining infrastructure changes with the shutdown of illegal industrial units, officials aim to improve the overall water quality of the Yamuna [1, 2, 3].

The conflict between the Water Minister's focus on structural turbulence and activists' focus on chemical effluents highlights a dual-pronged pollution problem. While redesigning the barrage may reduce the visible symptoms of froth, the long-term health of the Yamuna depends on the government's ability to successfully police industrial dyeing units and relocate informal washing sites.
