Navi Mumbai's Water Supply Strategy: A Multi-Source Approach to Meet Growing Demands

Strategic Insights -

As Navi Mumbai continues to grow and develop at a rapid pace, driven by large-scale infrastructure projects like the Navi Mumbai International Airport and Mass Housing schemes, the region's water supply systems face increasing pressure. To address this, the City and Industrial Development Corporation (CIDCO) has devised a comprehensive roadmap, leveraging existing sources and developing new ones like Balganga Dam and Kondhane Dam to meet the projected water demand of 1,275 million litres per day (MLD) by 2050.

Key Takeaways:

  • CIDCO is executing a multi-source water supply strategy to cater to the projected water demand of 1,275 MLD by 2050 in the CIDCO and NAINA areas.
  • The corporation is drawing from existing sources like Hetawane Dam, Maharashtra Jeevan Pradhikaran (MJP), Navi Mumbai Municipal Corporation (NMMC), and Maharashtra Industrial Development Corporation (MIDC), while developing new reservoirs such as Balganga and Kondhane dams.
  • The proposed Kondhane Dam, located on the Ulhas River, is expected to be a major water source for the region with an initial supply of 250 MLD, later scaled up to 350 MLD.
  • CIDCO has requested additional allocations from current sources, with the Maharashtra government approving an additional quota of 120 MLD from Hetawane Dam in August 2020 for Rs. 119.80 crore.
  • The Hetawane Water Supply Scheme augmentation, underway in four phases, is expected to be completed by June 2029, with 41% completion of the water treatment plant, 8.5% of the raw water tunnel, and 25.7% of the pure water tunnel.
  • CIDCO has engaged leading project management consultancies to oversee water tunnel and treatment plant construction.

Statistics:

  • Proposed water demand in CIDCO and NAINA areas by 2050: 1,275 MLD
  • Initial supply from Kondhane Dam: 250 MLD (later scaled up to 350 MLD)
  • Additional quota allocation from Hetawane Dam: 120 MLD
  • Total allocation from Hetawane Dam: 270 MLD
  • Completion timeline for the Hetawane Water Supply Scheme augmentation: June 2029
  • Current progress: Water treatment plant (41%), raw water tunnel (8.5%), and pure water tunnel (25.7%)
