Indore Smart City: leading by example

Indore has earned the distinction of being India’s cleanest city for eight consecutive years, a remarkable achievement that stems from its comprehensive smart city initiatives. The city’s transformation began in 2016 when it launched aggressive waste management reforms under the Swachh Bharat Mission and Smart Cities Mission.

Waste management revolution

Indore’s waste management system has become a global model. The city achieved 100% door-to-door collection and segregation by 2016, covering all 85 wards with over 850 GPS-enabled vehicles. Waste is segregated into six categories including dry waste, wet waste, hazardous waste, and sanitary waste. The city’s waste processing facility handles 645 tonnes of recyclable waste daily, while 550 tonnes of organic waste is converted into compost every day.

The recyclable waste is sold to recycling industries, while non-recyclable materials are sent to cement plants. Construction waste is processed separately to create bricks and paver tiles. This circular economy approach has enabled Indore to earn 4 crore annually from waste management while clearing its legacy dumpsite at Devguradia, which had accumulated over 1.3 million metric tonnes of waste.

Green transportation and renewable energy

Transportation in Indore has embraced sustainability with the introduction of bio-compressed natural gas buses. About 20 tonnes of food waste is collected daily and converted into 750-800 kg of bioCNG, which powers city buses and is sold as cooking fuel to hotels.

The city has integrated solar energy into its infrastructure through rooftop solar panels on public buildings and LED street lighting. These initiatives align with smart city objectives to generate at least 10% of energy requirements from solar power. The comprehensive approach includes smart meters, energy-efficient buildings, and solar-powered street lights that reduce transmission losses and maintenance costs.

Surat Smart City: energy and water efficiency

Surat, located on the banks of the Tapi River in Gujarat, has emerged as a leader in sustainable urban development. The city generates 34% of its energy from renewable sources and has won the Best Performance award from India’s Ministry of Housing and Urban Affairs for three consecutive years.

Smart energy solutions

Surat has implemented LED street lighting with smart monitoring systems across the city, significantly reducing energy consumption. The upgrade from traditional lighting to energy-efficient LEDs powered by solar energy has resulted in reduced maintenance costs and lower environmental impact. Smart traffic management systems complement these efforts by dynamically adjusting traffic signals to minimize idle time at intersections, thereby reducing vehicle emissions and improving air quality.

The city’s renewable energy initiatives extend to solar panels installed on public buildings including schools, hospitals, and government offices. These installations generate clean energy while reducing overall energy costs and carbon footprint.

Water conservation and management

Surat stands out as the only city in India that treats all its sewage water and generates revenue from the process, which subsidizes operational and maintenance costs. The city has established rainwater harvesting systems in both public buildings and residential areas, alleviating pressure on municipal water supplies while mitigating urban runoff impacts.

Smart water meters have been deployed throughout the city to monitor consumption patterns and reduce water wastage. The implementation of IoT-based sensors for monitoring water quality enables real-time tracking and swift intervention when needed. This integrated approach to water management ensures sustainability while maintaining service quality for Surat’s 7 million residents.

Urban greening initiatives

Surat has created biodiversity parks using native flora that improve air quality, restore polluted ecosystems, and provide green spaces for residents. The city aims to increase green cover from 18% to more than 25%, demonstrating its commitment to balancing urban development with environmental conservation.

Bhubaneswar Smart City: sustainable mobility

Bhubaneswar, the capital of Odisha, was ranked first among 98 cities in the Smart City Challenge, earning recognition for its comprehensive approach to sustainable urban development. The city has focused on creating user-friendly transport systems that offer flexibility, intelligence, and sustainable alternatives.

Electric buses and public transport

The Mo Bus system, launched in 2018 by the Capital Region Urban Transport, has transformed Bhubaneswar’s public transportation. The fleet now spans 600 kilometers across 67 routes, serving over 100,000 passengers daily-a remarkable 200% increase in ridership since its launch.

Electric buses form a key component of the Mo Bus fleet, designed to reduce emissions and promote cleaner air. By introducing electric buses, Bhubaneswar has made significant strides in improving air quality and reducing noise pollution. The system prioritizes safety and inclusivity with CCTV cameras, emergency panic buttons, and priority seats for women, children, seniors, and people with disabilities.

The Mo Cycle Public Bicycle Sharing system, launched in 2018, introduced 2,000 bicycles at over 400 stations across the city. Available 24×7 through a mobile app, the service offers the first 30 minutes of each ride free of charge. Users can locate nearby stations, unlock bikes through QR code scanning, and return them to any station, encouraging shared use and reducing traffic congestion.

The bikes feature adjustable seats, utility baskets, and GPS tracking for safety and convenience. The Bhubaneswar Development Authority painted dedicated cycling lanes on roads to ensure safer riding experiences. The system integrates with the Mo Bus network to provide first and last-mile connectivity.

Inclusive electric mobility

In 2022, Bhubaneswar introduced Mo E-Ride, an eco-friendly e-rickshaw service that connects people to bus stops. The initiative actively recruits women, transgender individuals, and people living with HIV as drivers, creating employment opportunities while promoting social inclusivity. In 18 months, 150 individuals from marginalized groups were trained and inducted, with 80 drivers now operating the network.

Smart infrastructure and waste management

Bhubaneswar has installed LED street lights throughout the city and plans to expand rooftop solar panels to enhance the green energy sector. The city’s comprehensive waste management system includes plans for waste-to-energy plants that will convert organic waste into usable power, further reducing the environmental footprint.

The city has developed an Intelligent City Operations and Management Centre that oversees traffic management, parking, bus operations, smart utilities, and emergency services. This integrated approach ensures efficient resource management and rapid response to citizen needs.

Common threads of success

These three cities share common elements that drive their success. Citizen participation forms the backbone of all initiatives, with extensive consultation and awareness campaigns ensuring public buy-in. Technology integration through IoT sensors, GPS tracking, mobile apps, and smart meters enables efficient resource management. Public-private partnerships facilitate implementation while maintaining accountability.

The focus extends beyond infrastructure to creating circular economies where waste becomes a resource, water is conserved and reused, and renewable energy reduces carbon footprints. These smart cities demonstrate that sustainable urban development is not just about technology-it’s about reimagining how cities function to serve both people and the planet.

What do you think? How can other Indian cities replicate these successful smart city initiatives? What role should citizens play in driving sustainable urban transformation?
