Hindustan Zinc, a company of Vedanta Group in Zinc-Lead-Silver business has come forward and built Udaipur’s fist sewage treatment plant (STP) that treats 30% of the sewage generated by the city of lakes, a world’s class tourism destination. Udaipur generates about 70 million litres of sewage per day and Hindustan Zinc Sewage Treatment Plant is treating 20 million litres per day. This STP has been built with a cost of Rs. 170 crore and has been constructed and commissioned on ‘Design Build Own Operate and Transfer’ basis in association with Government of Rajasthan.
On an average, Udaipur city generates about 70 million litres of sewage per day and cleaning this sewage has been a challenge. Currently, most of the sewage is travelling to various lakes leading to contamination of water, polluting lakes and thereby affecting overall beauty of these lakes. The only solution that was evident was constructing a large scale Sewage Treatment Plant that could take the load of treating this massive sewage. This treatment of sewage would not only keep the lakes clean, a strong move towards clean environment, but would also help in retaining the majestic looks of these lakes that attract lakhs of tourists every year.
Not just treating sewage, the Hindustan Zinc Sewage Treatment Plant, in the process, would also be generating a large quantity of manure that will be sold by Udaipur Municipal Corporation to the local bodies. This initiative itself is estimated to generate revenue of Rs. 1 crore every year. To ensure there is no piling-up of stocks of manure, the Udaipur Municipal Corporation will be disposing off the manure on fortnightly basis.
Hindustan Zinc, adhering to its commitment towards clean green environment and maintaining highest standards of waste management, commissioned this Sewage Treatment Plant in 2014. Hindustan Zinc ha also started the work relating to diverting domestic sewage pipeline into large pipe-lines which would lead to the Sewage Treatment Plant, to reduce further flow of sewage in the lakes.
The company is one of the pioneers in adopting clean green technology in running its plants. Saving water has always been a focus area for Hindustan Zinc. While maintaining the global benchmark and working continuously towards water conservation, the company has been successfully reducing its water footprints by reducing the water consumption every year. All the business locations of Hindustan Zinc are working on zero discharge principle, while putting on efforts and research for gainful utilization of waste generated by them.
Hindustan Zinc Sewage Treatment Plant project is a major step not only towards treatment of sewage in Udaipur but also a significant initiative towards building a sustainable environment and conservation of water.
