Keeping Kumbakonam Pristine
Inside InfraEn's Sewage System Revolution
Kumbakonam, often referred to as the “Temple Town” or “City of Temples,” is renowned for its spiritual heritage. With around 188 Hindu temples within its municipal limits and several thousands more in the surrounding areas, the city attracts millions of visitors each year. The influx of devotees, especially during festivals, underscores the need for a robust sewage management system to maintain public health and cleanliness.
Revolutionizing Sewage Management
The Underground Sewerage System (UGSS) project in Kumbakonam, managed by InfraEn, has been a game-changer for the city. InfraEn has revolutionized the city’s infrastructure, effectively managing the UGSS system across 12.58 sq. km and serving 140,113 residents. The extensive network includes 161.477 km of sewer lines, 52.55 km of pumping mains, 7,676 manholes, and 20,138 house connections, supported by 9 pumping stations and 9 lifting stations, ensuring seamless service and reliability.
Advanced Sewage Treatment
At the heart of the UGSS project are its Sewage Treatment Plants (STPs), which have a combined capacity of 17 million litres per day (MLD). Utilizing the Activated Sludge Process (ASP) technology over a 15-acre area, these plants ensure effective sewage treatment before discharge, protecting the local environment.
Rigorous Maintenance and Monitoring
Continuous inspection and maintenance are vital to the success of the UGSS. This includes quarterly sewer line cleaning using high-pressure jetting, rodding machines, and robotic cleaners, as well as monthly checks and annual overhauls of pumps to ensure less than 1% downtime. The system is monitored 24/7 by automated systems and a dedicated team of 75 operators and technicians. Additionally, a specialized 10-member response team with mobile units is ready to address emergencies within an hour.
Efficient Data Management and Community Engagemen
Data management is meticulous, with real-time digital logging, monthly reports, and annual reviews driving continuous optimization. The community is kept informed and engaged through quarterly meetings, workshops, and media campaigns promoting safety and proper sewage disposal.
Efficiency During Mahamaham Festival
During the 2016 Mahamaham festival, which drew nearly 2 million visitors to Kumbakonam, InfraEn’s management excelled in maintaining seamless UGSS operations. Despite the massive influx of visitors, the system upheld high standards of public health and environmental safety.
Long-Term Impact and Benefits
Over the past 11 years, the UGSS project has significantly improved public health in Kumbakonam, with a 60% reduction in waterborne diseases. Effluent discharge standards have been met, reducing pollution in local water bodies. Operational efficiency has been enhanced, cutting maintenance costs by 15% through preventive measures. This project demonstrates successful urban infrastructure management, leading to major improvements in Kumbakonam’s sewage system and residents’ quality of life.
Conclusion
InfraEn’s UGSS project in Kumbakonam is a testament to the impact of well-
managed urban infrastructure. It has not only met the current needs of the city but also prepared it for future demands, ensuring a cleaner and healthier environment for residents and visitors alike. The transformation of Kumbakonam’s sewage management is a model for other cities to follow, showcasing how innovative solutions can drive sustainable urban development.
