    JICA Assisted Ganga Action Plan II

    Varanasi, Uttar Pradesh, India

Project Summary

Project
Situated along the bank of the Ganges River, Varanasi is an ancient city and one of the most important tourist centers in the world. However, it is ill-equipped to properly treat its waste, resulting in unhygienic living conditions, significant pollution, and poor water quality of the Ganges River. With only 33 percent of Varanasi’s sewage currently being treated, Uttar Pradesh Jal Nigam retained NJS Engineers India Pvt. Ltd. to analyze the sewer system and recommend improvements to achieve a 90 percent treatment rate prior to discharge. To keep the INR 4.5 billion project on budget and on schedule, NJS required flexible, interoperable structural design and hydraulic modeling and analysis software.


Solution
Using Bentley applications, NJS evaluated and suggested improvements for more than 800 kilometers of sewer network. The team prepared a web-based GIS database for the entire project, updated the sewerage network inventory, modeled, and analyzed existing and proposed sewerage systems, prepared system rehabilitation and expansion plans, and identified more efficient operational strategies. Working in a web-based, integrated design environment using Geo Web Publisher, SewerGEMS, and STAAD.Pro accelerated information sharing and improved engineering solutions and productivity.


Outcome
The flexibility and interoperability of Bentley applications enabled NJS to automatically generate hydraulically coherent models from CAD drawings and reduce the number of large-scale manual drawings by 38 percent. Geo Web Publisher’s easy-to-use interface made it revolutionary for client relations as it facilitated collaborative review processes that shortened design review sessions, avoided rework, and conserved funds. Overall, Bentley’s integrated software saved 100 resource hours and INR 180 million in project costs.


Software
NJS used Geo Web Publisher and AssetWise to develop a database for the entire city of Varanasi that can be used for asset lifecycle information management to operate and maintain existing and future area sewerage systems. Using SewerGEMS enabled better capacity planning and ensured the team could analyze the sewerage designs and provide recommendations in a timely and cost-effective manner. The ability to incorporate the models developed in SewerGEMS into the GIS database enhanced collaboration and optimized information mobility among the project team. NJS relied on STAAD.Pro to design and review structural engineering elements of the project.

Outcome/Facts
  • Using Bentley design and analysis software, NJS analyzed the current sewerage system in Varanasi and made recommendations to improve water treatment capacity by 66 percent in India’s oldest city and one of the oldest in the world.
  • Per questo progetto, NJS si è avvalsa di SewerGEMS per modellare e analizzare oltre 800 km di reti fognarie.
  • Geo Web Publisher e AssetWise hanno permesso al team di sviluppare un database GIS integrato online per facilitare la gestione delle informazioni sul ciclo di vita, ai fini dell'operatività e della manutenzione dei sistemi fognari esistenti e futuri a Varanasi.
  • La flessibilità e l'interoperabilità delle applicazioni Bentley ottimizzano la mobilità delle informazioni e la collaborazione per migliorare la produttività e la precisione di modellazione, riducendo le ore-risorse e risparmiando 180 milioni di rupie.
  • Il progetto migliorerà la qualità dell'acqua del fiume Gange e le condizioni ambientali a Varanasi, a vantaggio anche della qualità di vita dei residenti e dei turisti.
