Chennai Metrowater is set to restart partial operations at the Minjur desalination plant within two months to alleviate water shortages in North Chennai.

Key Takeaways

  • Minjur plant to begin partial operations in approximately two months.
  • Initial production target set at 20 million litres per day (mld).
  • Primary beneficiaries include Tiruvottiyur, Manali, and Madhavaram zones.
  • The facility has been non-operational since November 2024.

In a significant move to bolster urban water security, Chennai Metrowater is preparing to restart the Minjur desalination plant. The city's first desalination facility is slated to begin partial operations within the next two months. While the plant possesses a massive capacity to treat 100 million litres of seawater daily (mld), the agency intends to start with a controlled output of 20 mld to stabilize the supply in North Chennai.

Why This Matters

The restoration of this plant is critical for the socio-economic stability of Chennai's northern suburbs. BozokMedia analysis shows that providing a consistent water supply to industrial and residential hubs like Tiruvottiyur, Manali, and Madhavaram will significantly reduce the dependency on erratic tanker supplies and groundwater.

The partial reactivation of the Minjur plant is a strategic necessity to mitigate the perennial water scarcity in Chennai's industrial corridors.

The facility had been sidelined since November 2024 following the termination of the contract with its previous operating company. Currently, intensive maintenance work is underway, including the cleaning of intake sumps and the replacement/removal of crucial Reverse Osmosis (RO) membranes. Metrowater Managing Director T. Anand has personally inspected the site and directed officials to expedite the restoration process.

Historical Background

The Minjur desalination project was envisioned as a cornerstone of Chennai's drought-proofing strategy. By leveraging seawater, the city aimed to create a weather-independent water source. The recent hiatus due to contractual disputes highlighted the vulnerability of the city's water infrastructure, making this revival a top priority for the Tamil Nadu government.

Did You Know?: Desalination is a high-tech process that uses extreme pressure to push seawater through membranes, leaving salt and impurities behind.
