In Navi Mumbai, the City and Industrial Development Corporation (CIDCO) has launched a series of critical water infrastructure projects across the state. These initiatives aim to ensure a reliable and sustainable water supply for the city, which is projected to require as much as 1,257 million litres per day (MLD) by the year 2050. With Maharashtra’s urban centers expanding rapidly, the move represents a forward-looking approach to safeguarding public utilities in a high-growth zone.
At the heart of this development is the phased expansion of the Hetawane Water Supply Scheme. The massive project is being executed in four key phases and is designed to boost overall water capacity and efficiency in distribution. CIDCO officials reported that as of mid-2025, 41 percent of the water tunnel work has been completed, while progress on the pure water tunnel has reached 25.7 percent. The full scheme is expected to be operational by June 2029 and will serve as one of the primary sources of supply for Navi Mumbai’s growing needs.
To further bolster long-term capacity, CIDCO is also actively developing alternative water sources. The Kondhane Dam, being built on the Ulhas River, is one such project. It is expected to initially provide 250 MLD, with infrastructure in place to scale up to 350 MLD if required. In parallel, work is also advancing on the Balganga Dam project. These two initiatives are expected to come online within the next four to five years and will play a crucial role in building future water resilience in the region.
In the interim, to manage current shortfalls and meet immediate demand spikes, the Maharashtra state government approved an additional allocation from existing resources. In August 2020, it sanctioned an extra 120 MLD from the Hetawane Dam, bringing CIDCO’s total allocation from this facility to 270 MLD. The decision came with a project cost of Rs 1.19 billion and has significantly strengthened the city’s short-term water security.
What makes these projects particularly important is their alignment with the broader goals of urban planning and infrastructure resilience. With climate variability impacting rainfall patterns and increasing the unpredictability of monsoon-fed reservoirs, diversified water sourcing and robust infrastructure have become vital. CIDCO’s emphasis on combining dam construction, water tunnel systems, and advanced water treatment reflects a holistic strategy that is designed not just for today but for decades to come.
Officials have also indicated that these projects will incorporate modern technology and sustainable engineering practices. For instance, tunnel boring and water purification processes are being built with efficiency and environmental standards in mind. By leveraging the latest techniques, CIDCO aims to reduce water loss in transit and improve quality at the point of consumption.
The projects are also expected to have a ripple effect on surrounding municipalities and industrial hubs. Navi Mumbai is not only a residential center but also home to commercial zones, IT parks, and logistics operations. Water demand from these sectors is also on the rise, making the planned infrastructure an economic enabler as much as an essential civic utility. It is anticipated that once the Kondhane and Balganga dams are completed, industrial water supply constraints in the region will ease, potentially inviting new investments into Maharashtra’s industrial corridor.
The state’s emphasis on proactive water management also places CIDCO among the more progressive urban development agencies in India. Unlike many cities where infrastructure struggles to keep up with demand, Navi Mumbai is preparing years in advance. This not only ensures a better quality of life for residents but also enhances the city’s resilience to climate and population shocks.
CIDCO’s strategy reflects a broader shift in Indian urban policy, where infrastructure is no longer reactive but anticipatory. With the combined forces of government planning, engineering execution, and financial backing, Navi Mumbai is positioned to emerge as a model for water infrastructure in the country.
As the Hetawane expansion continues and dam projects near key milestones, the next few years will be critical for execution. Stakeholders from both government and the private sector are watching closely. The successful completion of these initiatives could shape how other high-growth Indian cities tackle the challenge of future water demand in the face of climate uncertainty and urban sprawl.
CIDCO’s water infrastructure plan is not just a pipeline project. It is a blueprint for the future of urban planning in India — and Navi Mumbai is leading the way.
