Mumbai's Real Estate Sector Faces Water Crisis, Developers Seek Solutions

Mumbai's real estate sector is facing a new challenge as the Brihanmumbai Municipal Corporation (BMC) has suspended water supply to construction sites and imposed a 20% cut on commercial and industrial users. This decision comes amid critically low water levels in the city's seven lakes, which have fallen to just 10.35% of total capacity.

With water levels at an alarming low, developers are concerned that the restrictions could impact construction schedules, increase project costs, and potentially delay project deliveries if the crisis persists. The real estate industry is urging authorities to facilitate alternative water sources and provide regulatory support to minimize the impact on ongoing developments across Mumbai and the Mumbai Metropolitan Region (MMR).

Kamlesh Thakur, President of NAREDCO Maharashtra and Co-Founder and Managing Director of Srishti Group, acknowledged the severity of the current water shortage. 'The BMC’s decision to suspend water supply to construction sites reflects the seriousness of the situation and the need to prioritize drinking water for citizens. The industry understands the rationale behind these temporary measures and supports responsible water conservation during this period of stress.'

However, Thakur emphasized that the restrictions will inevitably have implications for the real estate sector. 'Construction activities such as concreting, curing, plastering, and finishing works are heavily dependent on a reliable water supply. Any prolonged disruption could impact project schedules, increase construction costs, affect labor productivity, and delay the delivery of homes and infrastructure projects.'

While many developers are increasingly adopting alternatives such as treated wastewater, recycled water, rainwater harvesting systems, and tanker supplies, the availability, scalability, and affordability of these options remain a challenge in several parts of the city. This is particularly relevant for affordable and mid-income housing projects, where project economics are already under pressure.

The current situation highlights the urgent need to accelerate the development of a robust treated-water ecosystem for construction and other non-potable uses. Greater availability of treated wastewater, expanded recycling infrastructure, and dedicated distribution networks can significantly reduce dependence on freshwater resources while ensuring continuity of development activities during periods of water stress.

Shilpin Tater, Managing Director of Superb Realty, shared similar concerns. 'The suspension of water supply to construction sites comes at a time when the real estate sector is witnessing strong momentum across Mumbai and the MMR region. Water is a critical input for several stages of construction, and any disruption can slow project execution, affect labor productivity, and increase dependence on private water procurement. The additional costs associated with sourcing water through tankers and alternative channels could place significant pressure on project budgets.'

Tater added, 'While the industry fully supports the need for water conservation during this period, this situation further reinforces the importance of adopting sustainable water management practices such as treated water usage, on-site water recycling, rainwater harvesting systems, and efficient construction methodologies that reduce water consumption. Facilitating access to treated and recycled water for construction activities will be crucial to ensure that ongoing projects continue with minimal disruption.'

Shraddha Kedia Agarwal, Director of Transcon Developers, echoed these sentiments. 'Mumbai's real estate sector has become increasingly accustomed to navigating regulatory and infrastructure-related challenges, but water remains one of the most fundamental resources required for construction. The current restrictions are likely to affect project planning, resource allocation, and execution schedules, particularly for developments in advanced stages of construction. Beyond the immediate impact on timelines, developers will also have to manage higher operational costs arising from alternative water sourcing arrangements.'

Agarwal stressed, 'Going forward, this situation should serve as a catalyst for greater integration of sustainable water management systems across developments, including treated water usage, greywater recycling, and enhanced rainwater harvesting infrastructure. A balanced approach that prioritizes water conservation while enabling essential construction activities through alternative water sources will be critical for the sector.'

Dhruman Shah, Promoter of Ariha Group, highlighted the importance of building greater resilience into urban infrastructure planning. 'The current water shortage highlights the importance of building greater resilience into urban infrastructure planning. For the real estate sector, the immediate concern is the impact on construction schedules, particularly for projects in critical execution stages where uninterrupted water availability is essential. Prolonged restrictions could create cascading effects across the project lifecycle, from construction progress to possession timelines and customer commitments.'

Shah concluded, 'This situation also underscores the need to accelerate the adoption of sustainable practices such as on-site water recycling, rainwater harvesting, and the use of treated wastewater for construction. With coordinated support from civic authorities, the sector can navigate the challenge while continuing to contribute to Mumbai's housing and infrastructure needs.'

The industry remains committed to working closely with the government and civic authorities to ensure responsible water management while maintaining the momentum of urban development. A collaborative and long-term approach will be essential to build resilient cities that can sustainably balance growth, resource conservation, and the housing needs of millions.
