Mumbai to Get 7.2 km Tunnel for

Mumbai is set to strengthen its future water supply with the construction of a 7.2-kilometre underground tunnel that will transport desalinated seawater from the upcoming Manori desalination plant into the city's water distribution network. The ambitious infrastructure project is aimed at reducing Mumbai's dependence on monsoon-fed lakes and improving water security for millions of residents. According to civic authorities, the tunnel will connect the desalination plant to key distribution points in Kandivli through Charkop and Mahavir Nagar. The tunnel will be built using advanced tunnel boring machines at depths of more than 100 metres below the ground. Construction is expected to begin soon and will take approximately 45 months to complete. The desalination project has an estimated cost of over ₹4,000 crore, with the tunnel itself accounting for more than half of the total investment. Once operational, the system will be capable of supplying hundreds of millions of litres of drinking water every day, helping bridge Mumbai's growing water demand. Officials believe the project will improve the city's long-term water resilience, especially during years of weak monsoon rainfall. By diversifying water sources, Mumbai aims to ensure a more reliable and sustainable supply for households, businesses, and industries. Why This Project Matters Reduces dependence on rainfall and reservoirs. Improves long-term water security for Mumbai. Supports the city's growing population and future development. Introduces modern underground infrastructure with minimal surface disruption. Conclusion The new desalination tunnel marks a major step toward securing Mumbai's future water needs. As climate change and urban growth continue to put pressure on traditional water sources, projects like this are expected to play a crucial role in ensuring a stable and sustainable water supply for the city.
