Avadi

Avadi is a western suburb of Chennai, and the headquarters of Avadi taluk located within the Thiruvallur district of Tamil Nadu, India. Situated at about 22 km from Chennai Central Railway Station, it is one of the four municipal corporations in the Chennai Metropolitan Area and is governed by the Avadi Municipal Corporation. It is surrounded by major defence establishments and is home to various universities and engineering colleges. The neighborhood is served by Avadi Railway Station of the Chennai Suburban Railway. As of 2011, Avadi had a population of 345,996, which is 10th most populous place in Tamil Nadu. It is home to the Heavy Vehicles Factory (HVF), Ordnance Factory Board (ODF) which houses Engine Factory and Combat Vehicles Research and Development Establishment (CVRDE). The lake in Avadi was known as Paaleripattu, which is now found only in very old land documents.

Etymology
The exact origin of the name 'Avadi' is not known. One version has it that it is the combination of "Aa" (meaning cow) and "Adi or gudi (kudi)" (meaning place in Tamil), indicating that the place had many cows. One of the more popular theories about the origin of the name is that it is an acronym for "Armoured Vehicles and Ammunition Depot of India". However, this is most likely a backronym invented more recently. The entity "Armoured Vehicles and Ammunition Depot of India" does not appear in any British records. This acronym is further disputed by the existence of a railway station going by the name of "Avadi" in the locality since 1873 before the establishment of defence industries.

Several British documents from the 19th century refer to the place as "Avady", which doesn't match the widely circulated acronym theory. The name Avadi (Avady) was already in use by 1856, when the first public railway was opened in the Madras Presidency. This predates the transfer of the Madras Presidency's arsenal from Fort St. George, India in the city of Madras, to Avadi, which was done sometime after 1870, which contradicts the popular acronym theory.

History
The suburb is part of the "auto belt" that developed when the automobile industry developed in Madras, primarily in the city's industrial north and west regions, in the early post-World War II years.

The famous session of the Indian National Congress was held at Avadi on 10 January 1955. This historical meet emphasised the importance of socialism and its impact on social development. Jawaharlal Nehru with Morarji Desai and other Congress leaders at the AICC session declared that a socialistic pattern of society was the goal of the Congress.

Lake


Avadi has a lake called Paruthipattu Lake. Spread over 200 acres and 2.64 km in length, the lake is located behind the Tamil Nadu Housing Board (TNHB) and Thirumullaivoyal. It was once a source of water for farmland irrigation. The body of water attracts many birds throughout the year. However, in the recent decades it has lost most of its area to indiscriminate building and encroachment. The Paruthippattu Lake area was renovated with a budget of 32 crores and converted into an eco-park that officially opened on 19 June 2019. The renovation added recreational facilities, a 3-km-long walking track, a central plaza and various greenery, while addressing the issues of encroachment and sewage pollution that had affected the once-neglected lake.

Waste management

Together with Thiruninravur and Poonamallee, Avadi generates about 210 metric tonnes of solid waste from around 120,000 households, which is dumped on a 17.78-acre site in Sekkadu, owned by the Avadi Municipal Corporation. In 2017, the municipal corporation planned to construct 33 decentralized compost processing plants at a cost of ₹ 109.6 million, each with a capacity to convert 4 tonnes of biodegradable waste into manure. Of these, 17 plants were operational as of February 2018.
