CASE STUDY
IMPROVING WATER ECOSYSTEM THROUGH TECHNOLOGY
CHALLENGE
The domestic sewage generated by Udaipur city is a potential threat to the environment and the aesthetic look of the lakes. Being a major national and international tourism destination, the city needed to streamline the sewage system which was becoming an area of concern for the administration. The challenge was to build a Sewage Treatment Plant and establish a well-organised modern sewage disposal network.
ACTION
Urban Improvement Trust, Udaipur and Hindustan Zinc joined hands and built Rajasthan's first Sewage Treatment Plant in Udaipur. The STP is currently treating 20 million litres of Udaipur domestic sewage per day, keeping the lakes clean. Successful implementation of 20 MLD Sewage Treatment Plant is proof that such a complex, technology intensive public-private partnership deal can be reached and has the potential to deal with the water scarcity problems of a state like Rajasthan.
Hindustan Zinc is in Phase 2 for further expansion by another 40 MLD with an investment of 80 crores.
HZL has signed an agreement for Phase 2 with Udaipur Smart City Limited (USCL) for design, construction, supply, installation, testing, commissioning and operation of an STP of another 40 MLD (25+10+5). This is for 15 years under the hybrid Annuity Model. We will have 75% of treated water from 25 MLD STP and 15 MLD STP output will remain with USCL.
OUTCOME
This has resulted in improving the ecosystem of the lake and fresh water consumption has correspondingly reduced. The results and overall impact of this particular initiative has been appreciated by the State Government and other authorities.
With the completion of Phase 2 we will be able to treat 100% of Udaipur City's sewage & significant reduction of fresh water consumption at the operational site.
GOING AHEAD
 |
25 MLD - will be commissioned by 2019 based on Moving Bed Bioreactor (MBBR) technology |
|
10 MLD - will be commissioned by 2020 based on Sequential Bioreactor (SBR) technology |
|
5 MLD - will be commissioned by 2020 based on Sequential Bioreactor (SBR) technology |
Apart from Phase 2 we have initiated another project for faecal sludge and septage management in Udaipur City. We signed an MoU with Centre for Policy Research, Udaipur Municipal Corporation and Vidhya Bhawan Society. With the treatment plant we will be able to treat the city's faecal sludge while the waste water will get treated in the STP.
