Located in the northernmost reaches of the city, Thiruvottiyur encompasses key localities such as Manali, Wimco Nagar, Kathivakkam, and Kaladipet, acting as a gateway where historic religious landmarks like the Thyagarajaswamy Temple meet sprawling industrial complexes. The area is home to a diverse workforce, primarily comprising industrial laborers, small-scale entrepreneurs, and a significant fishing community residing in over 20 coastal villages.

It is frequently in the news for toxic air and groundwater pollution, recurring oil leaks, and the depletion of marine life due to industrial discharge into the Ennore Creek. While the expansion of the Metro Rail to Wimco Nagar has provided a modern transport lifeline, residents continue to struggle with a dated underground sewerage system, severe water scarcity, and the health trade-offs of living in a high-density “hazardous chemical hub”.

The constituency is currently represented by KP Shankar of the Dravida Munnetra Kazhagam, who won in 2021.

Key citizen demands

Major citizen demands in Thiruvottiyur revolve around mitigating the heavy toll of industrialisation on public health and local livelihoods. Residents and environmental activists are calling for stricter monitoring of toxic effluents and gas leaks from nearby chemical and power plants that have severely polluted the air and Ennore Creek. For the large fishing community, the primary concerns include halting port expansions that threaten their traditional waters and securing better infrastructure at landing centers to combat sea erosion.

Urban improvements are equally prioritised, with long-standing pleas for a modernised sewerage system to prevent overflows, the completion of the Mattu Mandhai overbridge to fix chronic traffic bottlenecks, and the issuance of land pattas for residents in long-settled coastal areas. While the metro extension has improved transit, the community continues to push for better last-mile connectivity and a more reliable drinking water supply to match the area’s dense population growth.
