Over 50 organizations and 1,100 citizens in South Chennai have petitioned the Chief Minister to scrap the Mamallan reservoir project, citing fears of ecological destruction and increased flood risks.

  • Over 50 welfare associations and 1,100 citizens petitioned the CM.
  • Protesters warn the project could destroy the Kovalam-Nemmeli salt marsh.
  • The reservoir threatens the habitats of over 200 bird species.
  • Residents demand piped water and better rainwater harvesting instead.

Residents of the Old Mahabalipuram Road (OMR) corridor in South Chennai have launched a massive protest against the proposed Mamallan reservoir project. A coalition of more than 50 organizations and Residents' Welfare Associations (RWAs), representing approximately 1,100 citizens, have formally petitioned the Chief Minister seeking the immediate cancellation of the project.

While the government justifies the reservoir as a necessary step to meet the drinking water demands of the rapidly growing OMR area, locals argue that the environmental cost is far too high. They contend that the project will cause irreparable damage to the Kovalam-Nemmeli salt marsh, impacting both local livelihoods and the delicate regional ecosystem.

Environmental and Flood Risks

Local residents, including Bhuwana Raj from Sholinganallur, expressed frustration that while pipelines pass through their area to supply other parts of the city, OMR residents have been denied direct piped water for decades. "We do not want our name to be used to justify an ecological disaster," she stated, highlighting that the project could wipe out the habitats of over 200 local and migratory bird species.

Harsha Koda, co-founder of the Federation of OMR Residents’ Welfare Associations (FOMRRA), pointed out that residential areas in OMR are sandwiched between the Pallikaranai marshland and the Nemmeli wetlands. This positioning makes them highly vulnerable to flooding. The construction of the reservoir could exacerbate flood risks in critical areas such as Sholinganallur, Perumbakkam, Navalur, Siruseri, and Thalambur.

Urban expansion must not come at the cost of the natural drainage systems that protect our cities from catastrophe.

Why This Matters

BozokMedia analysis shows that the conflict in Chennai reflects a growing global trend where rapid urbanization clashes with vital wetland conservation. As coastal cities face rising sea levels and unpredictable monsoon patterns, destroying natural sponges like salt marshes and wetlands can lead to catastrophic urban flooding.

The protesters have called for a shift in strategy. Instead of large-scale reservoir construction in sensitive zones, they urge the government to focus on protecting existing water bodies, preventing illegal encroachments, and aggressively promoting rainwater harvesting. They are also demanding a transparent water allocation policy and scientifically planned infrastructure that respects natural drainage channels.

Did You Know?: Wetlands act as natural buffers, absorbing excess rainwater and preventing coastal flooding in metropolitan areas.
