Jaipur, Rajasthan, India Location

Dravyavati River was the active river of Jaipur which, over time and decades turned into a Nallah (Amanishah Nallah) due to rapid urbanization and select industrialization around the river. The river originates from the western slopes of Nahargarh hills flows thought the western side of Jaipur city from north to south and after flowing for about 47.5 km ultimately merge in Dhund River.

This rejuvenation project was based on the concept of watershed rehabilitation, flood prevention, pollution treatment and ecology landscape. Through comprehensive measures, the aim was to gradually recover the green views on both sides of the river and building up its aquatic ecosystem. Post implementation this project has really helped in restoring Jaipur’s historic river as the resting corridor for the public facilitating a "harmonious relationship between the citizens of Jaipur and nature".
