Ambattur

Ambattur is a northwestern urban hub of Chennai, India, located within the state of Tamil Nadu at coordinates 13.09818° N and 80.16152° E. Spanning an area of 40.36 square kilometers (15.58 square miles), the locality is positioned within the Ambattur taluk of the Chennai District and is surrounded by areas such as Avadi, Anna Nagar, Korattur, Padi, Mogappair, Kallikuppam, Surapet, Ayappakkam, Athipet, and Thiruverkadu.

Originally a village featuring extensive agricultural farmlands irrigated by the sprawling Ambattur Lake, the landscape has transformed significantly over time. The local terrain features primary waterbodies including the Ambattur Eri, the Chithu Oragadam Lake, and the larger Puzhal eri situated on the outskirts. The environmental upkeep of these waterbodies faces ongoing challenges, notably from the daily generation of nearly 250 tonnes of garbage by the local body, along with garbage dumping, water mining, building construction, and sewage pollution affecting the Chithu Oragadam Eri. Despite these urban pressures, the area supports diverse flora and fauna, serving as a habitat and frequent destination for various woodland birds, water birds, and other avian species. To manage surface water, the locality contains a stormwater drain network measuring 177.95 kilometers, which represents the largest network among the eight zones newly added to the Corporation of Chennai in 2011.
