Ujjain is a significant religious and ancient city in India. It is situated on the banks of the Shipra River in Madhya Pradesh and attracts pilgrims and tourists. The place is well-known for the Mahakaleshwar Jyotirlinga Temple, which is among the 12 revered Jyotirlingas in the country. Simhasth Kumbh Mela, which takes place every 12 years, is an event that attracts a huge influx of devotees across the world. Here we are going to discuss Case Study: Lake rejuvenation of Rudrasagar Lake using Rakeflow Mechanical Multi-rake Bar Screen.
The Challenge: Pollution and Degradation of Rudra Sagar Lake
The government of India started a mission to develop 100 smart cities. As part of India’s Smart Cities Mission, the government established a goal to transform Ujjain into a well-developed and modern city. “The Mahakal Lok Project” is a central focus to enhance the surrounding area of the Mahakaleshwar Temple. One of the most significant characteristics of this project was the rejuvenation of Rudra Sagar Lake. Rudra Sagar Lake spans around 17 acres, which is an essential part of the ecosystem of the lake. Over the years, due to the inflow of waste into the lake, the lake had suffered from pollution. The pollution is caused due to the waste in the river through stormwater drains. The stormwater drains were designed to manage the rainwater runoffs, but had become a channel to carry waste materials such as paper, plastic, wood, and other materials. This waste has affected the quality of water in the lake and makes it impossible for any restoration efforts to succeed. Now the lake, which once was a source of pride for the city become a polluted dumping ground. The waste material in the water obstructs the natural flow of the water.
Problem:
Now the problem arises, Ujjain receives an annual rainfall of 950mm during the three months of the monsoon period. When heavy stormwater events occur, thousands of cubic meters of wastewater and stormwater flow into the Rudra Sagar Lake, which makes this beautiful lake full of dirt and sludge. Rudra Sagar Lake had developed the water hyacinth, but the regular inflow of solid waste into the lake made it impossible for the lake rejuvenation activity to be successful. Now, the challenge was to restore the lake to its original state and make it a symbol of environmental revival, which can ensure that it can serve as an essential part of the Mahakal Lok Project.
The Solution: Adroit’s Role in Waste Management
Adroit offers the solution for rejuvenation of the lake that includes the installation of a multi-rake screen in the stormwater drains that can prevent waste from entering the lake. These screens were designed by Adroit to remove the sludge before it could be discharged into the water body by reducing the pollution and ensuring the rejuvenation efforts for the lake can move forward.
Adroit manufactured the 4 multi-rake screens that were capable of handling the water flow rate of 14.40 cubic meters per second. The width of each screen was 2600mm, whereas the height measured 5900mm with a bar spacing of 20mm, which can trap the sludge and waste material of all sizes, including paper, plastic, and other waste material. The screens that each weighs around 3500 kgs, were installed side by side in different channels of the stormwater drain to maximize the efficiency of these screens.
5 sluice gates measuring 3000 mm x 2000 mm were installed that can control and direct the stormwater flow in addition to the multi-rake screens. These gates ensure the smooth flow of the water, which allows the removal of waste material and proper management of the flow when heavy rainfall events occur. The collected waste materials from the screens are discharged onto a belt conveyor that is 19 meters long and can transport the waste to an outlet for further processing.
The system is a well-engineered solution for waste management and prevents the stormwater drains from pollution carriers, which ensures the protection of Rudra Sagar Lake from further contamination.
The Long-Term Impact of the Mahakal Lok Project
The Mahakal Lok Project focuses on developing a sustainable and eco-friendly urban area in Ujjain. This project tackles the stormwater waste management and fosters Rudrasagear Lake’s revival. This initiative aimed to create a sustainable and green urban environment with the goals of India’s Smart City Mission.
With the progress of the Mahakal Lok Project, the residents and visitors to Ujjain can enjoy the positive environmental impacts of this project. The enhancements to the city’s infrastructure can increase its flexibility to face the challenges of rain in the monsoon, and the renewal of Rudra Sagar Lake can showcase the potential of environmental sustainability with cultural heritage in urban areas.
Outcome
An important technology, the Rakeflow Multi-rake screen is used in cleaning Rudra Sagar Lake and enhancing the beauty of the Mahakal Lok Corridor. With the use of the Rakeflow Multi-rake screen, there can be prevention of floating waste such as plastic, paper, and other large sludge from entering the lake. The collected waste is removed through a conveyor and allowing the clean stormwater to enter the lake. The Mahakal corridor is now ready for the welcome of visitors.
Conclusion
The rejuvenation of Rudra Sagar Lake and the enhancement of the Mahakal Lok area in Ujjain are big examples of how urban development can align with environmental sustainability. The innovative solutions of Adroit, such as the installation of multi-rake screens and sluice gates, have played a crucial role in addressing the issues due to pollution that are affecting the restoration of the lake.
This project not only addresses and confronts the environmental issues and challenges, but also enhances the cultural experiences of the million visitors who travel to Ujjain annually. This shows how modern technologies and smart city initiatives are helpful to preserve the historical sites while improving the quality for local communities. The successful rejuvenation of Rudra Sagar Lake will contribute to making Ujjain a more attractive, sustainable, and eco-friendly destination for residents and tourists.
