Dravyavati River, also known as Amanishah nullah, originates in Jaisalya village, on the western slope of Amber hills. It flows through the Jaipur city, north to south over a length of 47.5 km, collecting storm and waste water from Naharika Nallah and Ambabari, the Ganda Nallah, and finally joins the Dhund river. Most of the Jaipur city's population stays within the 10 km periphery of Dravyavati river.
Deterioration
In 2016 the river was described as having deteriorated into a nullah, over the preceding century. The river had been comprehensively damaged by local pollution, garbage and debris.. Tata and sons were supposed to clear the debris and filth out of the River so as to change its status from Nullah to a river but nothing has happened yet. Moreover, the situation has worsened as of March 2020. 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. Sewerage mixed with domestic wastewater and industrial waste drains into the river through Nahri ka Nallah, Jawahar Nallah and other streams that come from structured and unstructured sewerage systems of the suburbs. Major flooding occurred in July 1981 that washed away many dams and embankments on the river. Subsequent encroaching development and pollution changed the nature of the river to the degree that it became known as "Amanishah nullah". Another flood in August 2012 left the city of Jaipur devastated, thousands homeless and many dead.
Rejuvenation project
In 2015 Tata Group produced a report for the rejuvenation of the river. This was approved by Rajasthan's state-level empowered committee in October 2015, having an estimated ten-year project cost, covering construction, operation and maintenance, of over 19 million Rupees. The contract for the project was awarded by the Jaipur Development Authority to a consortium comprising Tata Projects and the Shanghai Urban Construction Group with an initial cost of over 16 million Rupees to complete the work by October 2018. Construction works will include 85 check dams and 122 fall structures. As part of the rejuvenation project a combined footpath and cycle track running alongside the river from the source at Jaisalya to Goner, 47 km2, has been proposed.
