Mumbais Water Metro: A Lifeline for a Congested City

Mumbai is India’s financial capital and is very busy, but many people cannot go anywhere fast. It has a population of over 20 million people and its systems of transport are being overstressed. Suburban trains, buses, and roads are crowded with commuters that are experiencing agonizing waits and are packed together on the trains. With some relief expected from increased metro lines, upgraded roads systems, and water metro, this travel option will offer something new and different. Water metro will capitalize on Mumbai’s creeks, rivers, and coastline to help redefine the transportation model in urban systems by alleviating the inconvenience in congested travel, and to provide a new, sustainable way to travel in the future. As of June 2025, the water metro is accelerating in development and testing with possible service to begin in the year 2026. In this article we will look at opportunities and issues of Mumbais Water Metro: A Lifeline for a Congested City

Mumbai’s Transportation Crisis

Mumbai’s transport infrastructure is stretched to its limit. The suburban railway – known as the “lifeline” of Mumbai – carries more than 7.5 million passengers a day even though there is space for only 1,750 passengers per carriage (potentially). Buses operated by BEST carry somewhere in the region of another 5 million passengers (over daily, across 365 routes) and are held together by a single long-term government contract. Even worse, the fleet consists of largely outdated vehicles that are remarkable simply for the sheer number of passengers they transport  (Public Transport Decline).

 Furthermore, the increasing number of private vehicles, which have nearly tripled since 2008, is an issue and is compounded by infrastructure designed for a smaller population (Simson). The current demand for road space was never contemplated, leading to chronic underinvestment resulting in the worst levels of traffic congestion ever recorded in the world (Ibid.).

As air pollution and the time spent commuting in traffic increase (up to 4 hours, daily), productivity decreases, people’s time is wasted, and quality of life continues to dwindle. While Mumbai has invested heavily in improving “mass transit infrastructure” (e.g., the opening of Metro line Aqua Line 3, (Aqua Line Info),  November 2022), There exists significant opportunity for new ideas as they will be implicated on a significant scale simply to keep up with the speeds of adaptation/reverting.

The Water Metro Concept

The water metro is a system that uses ferries as a public transport mode that connects areas that are located near water. Water metro, unlike ferries, connects waterfront areas with a standardised way of service, modern vessels, and means of transferring between and to other modes of public transport. Currently, Kochi, in India, is the only city with a full-fledged water metro to speak of, and it has been operating for approximately 8 months. The design of the Water Metro system, which includes air-conditioned boats, QR-code for the tickets, regular schedules and generally more frequent trips than ferries, has aided in making it a popular mode of transport (Kochi Water Metro).

Mumbai is an excellent geographical city for a water metro system and is built on islands – in fact 7 islands – and is surrounded by the Arabian Sea and beaches, as well as the creeks of Thane, Vasai, and river Ulhas. The natural systems like rivers and creeks could be used for water metro to connect suburbs like Navi Mumbai, Vasai-Virar, Thane, Kalyan, and Alibag that are separated from the metropolitan centre by road and rail conflicts.

Proposed Routes and Infrastructure

The Mumbai Water Metro, as outlined in a June 2025 feasibility report by Kochi Metro Rail Corporation Limited (KMRL), envisions 10 routes covering 250 km with 29 terminals (Water Metro Routes). Key routes include:

The system will use electric catamarans, which are eco-friendly, quiet, and designed for rough weather. Modern jetties with amenities like waiting areas and real-time schedules will enhance user experience. Unlike current small-scale ferries to Alibag or Gorai, the water metro will be a comprehensive, standardized network.

Current Status and Planning

The KMRL Water Metro is currently in the planning stage as of June 2025. Maharashtra’s Fisheries and Ports Minister, Nitesh Rane, has asked officials to come up with a detailed development plan (DPR) within three months of KMRL’s feasibility report (Project Update). They will be looking for public-private partnerships to help finance the project, whose estimated cost is Rs. 2,500 crore. If the timeline holds together, the water metro could be operational in 2026, providing commuters an alternative means of transport.

The Maharashtra Maritime Board and Mumbai Port Trust are in charge of the overall work, with KMRL providing valuable input, based on their experience in Kochi. The project aims to connect with existing transport systems like BEST buses and metro lines through multi-modal hubs and unified ticketing.

Challenges to Implementation

Despite its promise, the water metro faces significant hurdles:

1. Geographical Constraints: Unlike Kochi’s stable lagoons, Mumbai’s creeks and rivers, especially beyond Kalyan, are shallow and narrow. Barrages and bridges further limit navigation. Shallow-draft vessels are proposed to address this, but routes will primarily serve coastal areas.
2. Monsoon Disruptions: Mumbai’s monsoon, with its torrential rains, could disrupt services. While modern boats can handle rough weather, extended outages are possible, as seen with Alibag ferries. Robust vessel design and contingency plans are critical.
3. Last-Mile Connectivity: Water transport is point-to-point, serving only waterfront areas. Unlike metros, which cut through dense urban centers like Andheri or BKC, water routes may struggle to reach commercial hubs. Transit-oriented development (TOD) around jetties, with bus and metro links, is essential.
4. Urban Development Gaps: Many proposed routes pass through less-developed areas, limiting ridership. TOD can spur residential and commercial growth near jetties, but this requires long-term planning.

Solutions include using electric catamarans for sustainability, building modern jetties with amenities, and integrating with other transport modes. For example, Thane’s water metro station could connect to the upcoming circular metro and coastal road, creating a seamless hub (Thane Connectivity).

Economic and Social Impact

The water metro could change Mumbai’s economy and society. It can enhance productivity by reducing travel time, especially for people coming from Mumbai and the suburbs, such as Navi Mumbai, which are also growing IT hubs. The new Dibba Patil International Airport will also open soon and will be linked and accessible to a number of water metro routes, which will become appealing to businesses and travellers. 

As connections improve, it will likely develop economically, particularly in coastal suburbs such as Vasai-Virar and Kalyan, which have both seen massive increases in residential activity and development. Employment opportunities for suburban residents are also increased by this infrastructure and investment, as these regions can reduce the reliance on South Mumbai for jobs and activity to grow.

Socially, the water metro has the potential to democratise transport. Cheap fares and reliable services may attract a diverse clientele from all income groups, as opposed to private vehicles used by the wealthy. Coastal communities, which have often been underserved, could enjoy improved access to jobs, education, and healthcare, thereby improving their relationship to the urban poly-nexus. 

Tourism will also benefit. The routes to Elephanta Caves, Gorai Beach, and Alibag could attract a greater number of visitors, thereby enhancing local economies. A beautiful journey along the Mumbai coastline may just itself, attract people from outside of Mumbai, furthering global interest in the cultural and tourist landscape of the city. 

Environmentally, the water metro has several advantages around sustainability. Electric catamarans will have zero emissions, minimizing the carbon footprint of the city. If commuters can be moved from the roads to the water, it can reduce traffic, which in turn will also improve air quality – a major challenge in Mumbai.

Comparison with Other Cities

Kochi’s water metro is the primary inspiration due to its modern boats and integrated ticketing. Sydney’s ferry system provides another model as its ferry ticketing can seamlessly integrate with bus and train tickets. The city of Venice operates uniquely relying solely on water transportation, demonstrating how transportation can shape a city’s identity. Mumbai can take advantage of these best practices, while being mindful of ensuring more frequent service, modern infrastructure for loading/unloading boats, and easy access to multi-modal systems. 

Unlike Kochi’s lagoons, Mumbai’s waterways are much busier and cannot follow Kochi’s model as is. This means we need solutions specific to Mumbai, such as shallow-draft vessels. Learning from Sydney, we can improve our prospects by requiring water metro users to buy their tickets through the Mumbai 1 app; already over 75,000 downloads related to metro services (Mumbai 1 App).

Future Prospects

The water metro is not just a transport project; it is a vision for the future of Mumbai. With a growing city, we will have new developments like the Navi Mumbai International Airport and the Mumbai Trans Harbour Link – connectivity will be critical. The water metro can complement other projects and be part of a bigger picture in great transportation.

In the long term, the water metro system could address more routes or possibly be integrated into larger regional transport schemes or even support, for example, the Surya Regional Water Supply Scheme (Surya Scheme). The water metro is significantly reducing the number of people who will rely on roads and Rails; it could free up congested roads and congestion on the compact rail networks, lead to improvements in air quality and livability.

Conclusion

The Mumbai Water Metro project is a promising step for a city dealing with a transportation crisis. With its waterways, Mumbai can provide commuters with faster, greener, better commutes to avoid congested rail and road traffic. While there are still hurdles like shallow creeks and monsoons to consider, innovations like vessels designed for shallow waters and transit-oriented development (TOD) offer solutions as well as a path to a successful water metro.

As the Maharashtra government ramps up momentum toward a launch in 2026, the prospect of the water metro is a thrilling one for many Mumbaikars. If executed successfully, a water metro for Mumbai could change the way Mumbai-ites turn. Instead of simply tolerating commutes, these commuters might enjoy them. The state’s commitment to the water metro demonstrates its belief in alternatives to helmets, horns, and other extreme forms of urban transport, one they can’t control too strongly around The City That Never Stops. This may bring into existence the city that Mumbaikars deserve.
