Utility services

The water supply in Delhi is managed by the Delhi Jal Board (DJB). As of 2006, it supplied 650 MGD (million gallons per day) of water, while the water demand for 2005–06 was estimated to be 963 MGD. The rest of the demand is met by private and public tube wells and hand pumps. At 240 MGD, the Bhakra storage is the largest water source for DJB, followed by the Yamuna and the Ganges. With falling groundwater level and rising population density, Delhi faces severely acute water shortage. Delhi daily produces 8000 tonnes of solid wastes which is dumped at three landfill sites by MCD. The daily domestic waste water production is 470 MGD and industrial waste water is 70 MGD. A large portion of the sewerage flows untreated into the river Yamuna.

The city's per capita electricity consumption is about 1,265 kWh but actual demand is much more. In 1997, Delhi Vidyut Board (DVB) replaced Delhi Electric Supply Undertaking which was managed by the MCD. The DVB itself cannot generate adequate power to meet the city's demand and borrows power from India's Northern Region Grid. As a result, Delhi faces a power shortage resulting in frequent blackouts and brownouts, especially during the summer season when energy demand is at its peak. Several industrial units in Delhi rely on their own electrical generators to meet their electric demand and for back up during Delhi's frequent and disruptive power cuts. A few years ago, the power sector in Delhi was handed over to private companies. The distribution of electricity is carried out by companies run by Tata Power and Reliance Energy. The Delhi Fire Serviceruns 43 fire stations that attend about 15,000 fire and rescue calls per year.
State-owned Mahanagar Telephone Nigam Limited (MTNL) and private enterprises like Vodafone Essar, Airtel, Idea cellular, Reliance Infocomm, and Tata Indicom provide telephone and cell phone service to the city. In May 2008, Airtel alone had approximately 4 million cellular subscribers in Delhi. Cellular coverage is extensive, and both GSM and CDMA(from Reliance and Tata Indicom) services are available. Affordable broadband penetration is increasing in the city.
