[1]: 167 Most of the Jaipur city's population stays within the 10 km (6.2 mi) periphery of Dravyavati river.
One cause of the pollution is the collection of storm water from adjoining areas such as Ambabari, the Walled City of Jaipur, Sanganer town and Pratap Nagar.
Subsequent encroaching development and pollution changed the nature of the river to the degree that it became known as "Amanishah nullah".
This was approved by Rajasthan's state-level empowered committee (SLEC) in October 2015, having an estimated ten-year project cost, covering construction, operation and maintenance, of over 19 million Rupees.
[6][2] As part of the rejuvenation project a combined footpath and cycle track running alongside the river from the source at Jaisalya to Goner, 47 km (29 mi), has been proposed.
