New District demand[edit]

People of northern and eastern Tiruvallur district demanding for a new district headquartered in either Ponneri or Red Hills by bifurcating the large Tiruvallur district.[2][3] Some people consider Red Hills as a gateway of these regions. Where regions like Gummidipoondi, Ponneri, Pazhaverkadu depend on Red Hills rather than current district headquarters Tiruvallur. Some people demanding that Ponneri should be the headquarters of the new district. The possibility of creating Ponneri district by bifurcating Tiruvallur district by carving out the entire region of Ponneri, Gummidipoondi and Uthukkottai taluks. The two possibilities of creating Red Hills district by bifurcating Tiruvallur district:

  1. Entire region of Ponneri, Gummidipoondi, Avadi, Poonamallee taluks and parts of Uthukkottai taluk
  2. Entire region of Ponneri, Gummidipoondi and Uthukkottai taluks.

People demand a new district by considering the following:

  • To facilitate smooth agricultural activities.
  • To ensure balanced development of infrastructure in their region due to its proximity with Chennai city.
  • To keep people closer with the government and its services.
  • To help government to boost its revenue to maximum from this region.
  • To attract investments on manufacturing & logistics sectors.
  • To generate new employment opportunities.
  • To reduce excess burden on administration of large Tiruvallur district.
  • To manage administration of Chennai Metropolitan area.
  • To balance the development and ecosystem of Chennai Metropolitan area.


The word "Tiruvallur" is supposedly derived from the Tamil sentence "tiru evvull?" from "Tiru" (highness – a common prefix in South India for temple towns or cities) and "evvull" (where do I sleep?). So, Tiruvallur means, a place/town where, the god, Veera Raghavar asked a saint for a place to sleep for a night.[4]

Tiruvallur Don Area was originally known as Tiru-evallur which specifies the sleeping position of the holy lord "Perumal", in the Veeraragava temple of Tiruvallur. Later people began to refer it by names such as Trivellore and Tiruvallur. Today Tiruvallur is well known, one of the reason being the Veeraragava Temple, where Amavasya (the commencement of dark moon prior to the new moon) is considered an auspicious day for the lord and so for the people of the town.[5]

The district of Tiruvallur has been carved out by bifurcating erstwhile Chengalpattu district (which was renamed as Chengalpattu-MGR/Kancheepuram at the time of 1991 Census). According to the said bifurcation Tiruvallur revenue division which included Tiruvallur, Tiruttani taluks and Uthukkottai and Pallipattu sub-taluks separated from Chengalpattu district along with Ponneri and Gummindipoondi taluks of Saidapet revenue division and formed this new district. At present this district comprises 9 taluks, namely Avadi, RK Pet, Ponneri, Gummidipoondi, Uthukottai, Tiruvallur, Poonamallee, Tiruttani, and Pallipattu.

In the far past, this region was under a chain of regimes commencing from the Pallavas during the 7th century ending with the Nawab of Arcot during the early part of 19th century when it came under the British rule. In 1687, the Golkonda rulers were defeated and the region came under the Moghul emperors of Delhi. The towns and villages of this region were the scene of Carnatic wars. Battles are said to have been fought in this region during the struggle for supremacy between the English and French. The town of Pulicat was the earliest Dutch possession in India founded in 1609 which was ceded to the British in 1825. With this, the region came under the British rule which ended on 15 August 1947 with India becoming independent.[4]


It is bounded on the north by Nellore and Chittoor districts of Andhra Pradesh state, on the east by the Bay of Bengal, on the southeast by Chennai district, on the south by Kanchipuram and Chengalpattu districts, on the northwest by Vellore and on the west by Ranipet district. The coastal region of the district is mostly flat; but in the other parts it is undulating and even hilly in some places.

The northern taluks of the district like Ponneri, Uttukkottai, Gummidipundi etc. do not have much to offer from the scenic point of view. In the Tiruttani taluk, a number of hillocks are found scattered. The soil of the district is mostly sandy, mixed with soda or other alkali or stony. Rocks found in and near the surface are in detached masses. Hence, the soil can't be termed as very fertile. The soil found nearer the sea coast is of the inferior erinaceous type which is most suited for raising casuarinas plants. No mineral of any importance is available in the district. There are not many hills of any considerable height in this district. A few conical hills or ridges of small elevation exist like the St. Thomas Mount. Certain hillocks are found in Tiruttani. Most of the hills and hillocks are rocky and no verdant vegetation is seen in the slopes of these hills. The area under forests in this district is quite meager.

The average normal rainfall of the district is 1104 mm. Out of which 52% has been received during Northeast Monsoon period and 41% has been received during Southwest Monsoon period.
