Bengaluru’s population has tripled to 15 million since the 1990s, overwhelming its water resources. The city’s current water supply, sourced from the Cauvery River (51%) and groundwater (49%), is theoretically sufficient to meet the daily demand of approximately 2,632 million litres. However, ageing infrastructure, energy-intensive transport of Cauvery River water (lifted from a reservoir ~350 meters lower than the city’s elevation and over 90km away) and unregulated borewells -over 500,000 unauthorised borewells and 14,000 government drilled wells, half of which are now dry, according to officials-, pose serious risks to long-term sustainability.  

These challenges disproportionately affect low-income communities, as water tanker prices shot up to ₹1,500-₹1,700 for a 12,000 litre load during summer months of last year – placing significant burden on households, especially since authorities had capped the price at ₹1,000 – ₹1,200.

Bengaluru generates nearly 1,940 million litres of wastewater daily, but 24% (nearly 500 million litres) is discharged untreated. Among the treated volumes only a limited proportion is reused: 30% for non-potable domestic uses, and 20% for commercial and industrial needs. This underutilisation underscores a missed opportunity for water reuse and reduction in freshwater extraction dependence.

Recognising that Bengaluru’s water crisis stems as much from failure in management as from absolute scarcity underscores the need to invest in circular water systems, improving urban water governance, and aligning city growth with sustainable water use principles.

Digital transformation in urban water management: Lessons for Bengaluru

Shirpur-Warwade in MaharashtraThis town is the first in India to achieve 100% smart water metering by installing 13,500 Automatic Meter Reading (AMR) devices. As a result, daily water demand saw a 33% reduction and billing delays fell from two months to five days.
Panaji Smart City projectOver 3,000 IoT-enabled smart water meters were installed in the city for real-time monitoring and management. This helped lower non-revenue water from 61% to 14% and saving ~4.8 crore litres of water annually.
Chennai Metropolitan Water Supply and Sewerage BoardThis city introduced a Metering-as-a-Service (MaaS) model through a Design-Build-Finance-Operate-Transfer framework. The goal is to achieve 90% metering coverage by 2025–2026, with a strong emphasis on reducing non-revenue water.

Beyond individual city initiatives, national programs such as the Jal Jeevan Mission (JJM) are  promoting large-scale adoption of smart technologies, and integration of IoT-based platforms, real-time monitoring, and automated billing systems. Global market trends reinforce this momentum. GSMA’s research projects that IoT connections in utility services across low- and middle-income countries (LMICs) will more than double by 2030, with water emerging as a key area alongside energy and sanitation.

The following takeaways outline what is needed to scale digital water innovations more effectively and equitably across Indian cities, especially Bengaluru:

Scaling digital water solutions requires more than just early-stage capital—it demands a clear and supported pathway from innovation to adoption. While mobilising risk capital through blended finance, CSR, and catalytic grants remains vital, it must be complemented by technical assistance, streamlined procurement processes, and regulatory clarity. Startups and MSMEs also need better access to market intelligence, pilot opportunities with utilities, and frameworks for product validation and certification. These elements, together, help bridge the gap from promising pilots to widespread deployment—ensuring that high-impact solutions can scale sustainably and equitably across diverse urban contexts.

Government procurement processes, often fail to keep pace with market evolution. This hinders the  scaling journeys of many promising solutions. Empanelment processes that assess due diligence, impact, and interoperability can help level the playing field—allowing state utilities and municipalities to access innovation without bureaucratic delay.

Digital and hardware innovations often lack clear certification pathways, which hinders adoption by utilities wary of unproven technologies. To build trust and ensure quality, there is a need for sector-specific certification protocols co-developed by regulatory bodies, standards agencies (such as Bureau of Indian Standards or the Jal Shakti Ministry), and innovation hubs in partnership with utilities. These should cover performance benchmarks, interoperability, and safety standards—particularly for water quality monitoring, IoT-enabled systems, and reuse technologies. Establishing such protocols will provide a structured validation route, helping utilities de-risk procurement and adopt new solutions with greater confidence.

From borewell monitoring to smart metering, nearly every innovation at the forum relied on decentralised data collection. Leveraging mobile operator networks, NB-IoT, and 4G/5G systems is essential for scaling cost-effective, last-mile data infrastructure—especially for utilities with limited in-house digital capacity.

Finally, forums like DUUF highlight the need for ongoing policy dialogue between innovators, regulators, and city planners. Smart technologies can only thrive when embedded into long-term water planning frameworks, supported by leadership, standards, and communities.

These enabling conditions apply not only to startups but also to mobile network operators, who are increasingly integral to smart water ecosystems. Insights from the Smart Cities Roundtable at Mobile World Congress 2025 outlined mobile operator’s transition from connectivity providers to full solution integrators offering IoT, AI, and data-driven platforms​. Their networks and platforms provide the backbone for real-time data collection, remote monitoring, and interoperability; key ingredients for scaling digital solutions like smart meters, IoT-enabled valves, and leak detection systems. Nokia’s presentation at the forum showcased its Open Industrial IoT (IIoT) and Integrated Operations Center (IOC) solution and made a compelling case for how mobile industry players are also evolving into orchestrators of smart infrastructure.

A key feature of Nokia’s approach is its interoperability: Utilities can integrate any IIoT-enabled device into a common platform for seamless data management, analytics, and operations. This reduces fragmentation, increases efficiency, and supports scalable digital transformation.

Globally, Nokia’s smart water solutions are already in use for instance, in Australia, Vodafone deployed Nokia’s NB-IoT technology to improve coverage, reduce power draw, and enable secure, low-latency water monitoring. In Vietnam, telecom operator Viettel implemented Nokia’s Integrated Operations Center for smart cities, centralising utility operations across sectors.

As India advances from 5G to 5G Advanced and eventually 6G, Nokia’s solutions—like digital twinning and AI-based asset monitoring—can be adapted to solve local water challenges. Their flexible architecture makes them well-suited for Indian utilities looking to modernise without overhauling existing infrastructure.
