Public utilities in Chennai are managed by established state and municipal boards, working to meet the demands of a rapidly expanding metropolis.
* **Electricity**: Managed and supplied by the **Tamil Nadu Generation and Distribution Corporation (TANGEDCO)**. While supply is generally stable, brief localized outages can occur during the monsoon season. * **Water and Sewage**: Handled by the **Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB or Metro Water)**. To combat historic water scarcity, the city relies heavily on desalination plants (like those at Minjur and Nemmeli) and rainwater harvesting, which is mandatory for all buildings. * **Waste Management**: Overseen by the **Greater Chennai Corporation (GCC)**. The city has increasingly moved towards privatized zonal waste collection (partnering with firms like Urbaser Sumeet) to improve door-to-door collection and source segregation. * **Piped Gas**: Piped natural gas (PNG) networks are currently being expanded across the city by **Torrent Gas** and **IndianOil**.
