CIDCO Launches Water Upgrade For Navi Mumbai Airport Zone

02 Jul 2025 CW Team

With the Navi Mumbai International Airport nearing commissioning and the wider Navi Mumbai Airport Influence Notified Area (NAINA) poised for rapid growth, the City and Industrial Development Corporation of Maharashtra (CIDCO) has embarked on a far reaching water augmentation programme across Raigad district.

“We are not only meeting today’s demand, we are building resilient infrastructure for tomorrow,” said Vijay Singhal, CIDCO Vice Chairman and Managing Director.

Long term demand

CIDCO projects water needs in its own and NAINA jurisdictions will rise to 1,275 million litres per day by 2050. To meet this, the agency is expanding existing sources—Hetawane Dam, Maharashtra Jeevan Pradhikaran (MJP), Navi Mumbai Municipal Corporation and MIDC—while developing new reservoirs at Balganga and Kondhane.

Key components

Hetawane Water Supply Scheme: four phase upgrade to lift output to 270 MLD; completion targeted for June 2029. Current progress: treatment plant 41 per cent, raw water tunnel 8.5 per cent, clear water tunnels 25.7 per cent.
Kondhane Dam (on the Ulhas River): initial supply 250 MLD, rising to 350 MLD; expected build time four to five years.
Balganga Dam: parallel project to bolster long term capacity.

To bridge the gap before the new dams come online, the state has already sanctioned an additional 120 MLD from Hetawane, against a payment of Rs 1.198 billion. An expert consultant is redesigning the network to utilise this quota.

Expertise and oversight

International project management consultancies have been engaged to supervise tunnel boring, treatment plant construction and quality control, ensuring the works meet global standards.

Once complete, the integrated network will secure water for the airport precinct, CIDCO townships and Panvel Municipal Corporation, underpinning the vision of a “Third Mumbai” and safeguarding supplies for decades to come.

Smart Roads, Smarter India

India’s infrastructure boom is not only about laying more kilometres of highways – it’s about building them smarter, safer and more sustainably. From drones mapping fragile Himalayan slopes to 3D machine-controlled graders reducing human error, technology is steadily reshaping the way projects are planned and executed. Yet, the journey towards digitisation remains complex, demanding not just capital but also coordination, training and vision.Until recently, engineers largely depended on Survey of India toposheets and traditional survey methods like total stations or DGPS to prepare detai..

What Does DCPR 2034 Mean?

The Maharashtra government has eased approval norms for high-rise buildings under DCPR 2034, enabling the municipal commissioner to sanction projects up to 180 m on large plots. This change is expected to streamline approvals, reduce procedural delays and accelerate redevelopment, drawing reactions from developers, planners and industry experts about its implications for Mumbai’s vertical growth.Under the revised DCPR 2034 rules, buildings on plots of 2,000 sq m or more can now be approved up to 180 m by the municipal commissioner, provided structural and geotechnical reports are certified b..
