Project:    Water Supply of Nabadiganta

Private Partner-Nabadiganta Water Management Limited (A SPV formed by Jusco & Voltas)

Concept of the Project

• Sector-V of Salt Lake City has been carved out from Bidhannagar Municipality in the year 2006 and Nabadiganta Industrial Township has been constituted by the Government of West Bengal. Since then Naba Diganta Industrial Township Authority (NDITA) is functioning as an ULB to give focussed attention to Sector – V, Salt Lake, the IT hub of West Bengal.

• NDITA is committed to creating proper Infrastructure & for providing comprehensive urban services to its Customers in the command area.

• NDWML was given responsibility to Design, Build and Implement all facilities of Water Supply after validation of design by NDITA / KMDA.

• Financing of the project is based on PPP/ BOOT Model where the Private Partners would bear 65% Project Cost and the revenues will be collected by them. Viability Gap Funding of 35% is being provided by Govt. of India through JNNURM. The cost of the UGR exclusive for Sector – V shall be borne by NDWML and Government of West Bengal on 50:50 basis.
