This presentation describes the efforts made by Nagarjuna Fertilisers and Chemicals Limited at water conservation. This ammonia based fertilizer manufacturer in the East Godavari district of Andhra Pradesh draws water for its cooling, process and township requirements from the Godavari River.
As a heavy user of water, the company has tried to reduce its drawals by modifying several processes and uses to bring about water use efficiency, reusing waste water, continuous online monitoring and plugging of leaks, and conducting awareness and training programmes for workers and township dwellers alike.
Water audits, rainwater harvesting and the use of treated effluent for green belts are among the other steps taken. As against a specific water consumption of 6.578 cubic meters per metric tonne of fertilizer output in 2002-‘03, the plant has come down to 5.529 cu m/MT in 2006-'07, which is closer to the best national figure of 4.816 cu m/MT for the ammonia based fertilizer industry.
This has been done in tandem with measures to reduce liquid effluent generation and discharge as well as energy conservation initiatives. The company has adopted a community based approach and is also actively engaged in sharing best practices in these areas with other similar industrial units.
