The article discusses the ongoing efforts to clean the Yamuna River in Delhi, led by local officials including Pravesh Verma. Multiple machines have been deployed to remove decades-old filth from the river's drains. This initiative indicates a concerted effort by the local government to address long-standing environmental issues in the region.

In addition to the machinery for cleaning, the article notes that new Advanced Continuous Pretreatment (ACP) plants are being constructed in areas lacking sewer lines. This development aims to provide better sanitation and waste management solutions for local villages and colonies, thereby improving the overall health of the environment and the river.

The context of the cleaning efforts takes place amid increasing awareness of pollution issues in Delhi, particularly with respect to the Yamuna River's deteriorating condition. The cleaning initiative, therefore, not only seeks to restore the river's ecosystem but also highlights the urgency for better infrastructure and waste-management practices in urban areas of India.
