No Wires, No Waste: What the "Water in India" Conference Revealed About LoRaWAN's Critical Role in India's Water Crisis

India is running out of water, not as a distant projection, but as a present-day engineering, governance, and operational emergency. When policymakers, utilities, technologists, and industry leaders gathered in New Delhi at the end of April 2026 for the "Water in India" conference, the scale of the challenge was immediately clear. So was something else: the technology to address it, at least for connectivity and metering, is already here, already deployed, and already proving its value on Indian soil.

The LoRa Alliance^® brought together a delegation of member companies — Semtech, Ripple Metering and Kerlink — to present the LoRaWAN^® ecosystem's full value chain for smart water management. What emerged from those two days was a compelling alignment between India's most urgent infrastructure problems and the capabilities that LoRaWAN uniquely provides.

This article summarizes the key presentations, the market context they addressed, and the strategic implications for utilities, system integrators, and policymakers looking to accelerate India's digital water transformation.

The Magnitude of India's Water Emergency

Before any technology conversation can land, the numbers need to be understood.

Six hundred million Indians currently face water stress. By 2050, per capita water availability is projected to fall below 1,000 cubic metres — down from 1,486 today and 1,816 as recently as 2000. India's Non-Revenue Water (NRW) rate averages 33% nationally, with a range of 25% to 52% across cities. Delhi's NRW sits at 42%. Bangalore's BWSSB (Bangalore Water Supply and Sewerage Board) targets 27%. In Mumbai, over 4,000 kilometres of pipelines operate without automatic cutoff mechanisms, causing chronic overflow losses. A thousand million litres per day leak from Delhi's distribution network alone.

These are not abstract efficiency metrics. They represent water that was treated, pumped, and pressurised — then lost before reaching a tap.

The scale of infrastructure investment already underway makes the deployment opportunity equally significant. The Jal Jeevan Mission (JJM), targeting tap water to every rural household, involves over 150 million connections and an annual operations budget of three lakh crore rupees. AMRUT 2.0 plans to expand ~2.68 crore taps in urban areas and lay ~6.5 lakh kilometres of water pipeline by 2030. The Swachh Bharat Mission 2.0 is planning ~4,780 sewage treatment plants across Indian towns.

The infrastructure is being built. The question is whether it will be smart.

The LoRa Alliance in New Delhi: A Complete Ecosystem Answer

The LoRa Alliance presented at the "Water in India" conference as a unified ecosystem, not as a collection of individual vendors. That framing — from chip to cloud, from device to dashboard — was deliberate and strategically important for an audience of utility decision-makers who needed to understand not just whether LoRaWAN technology works, but whether there is a mature, interoperable supply chain behind it capable of supporting national-scale deployments.

The Alliance's opening context slide set the tone: 125 million LoRaWAN devices are deployed globally, growing at 25% CAGR. Outside of China, LoRaWAN remains the leading LPWAN connectivity technology — a point reinforced by Omdia analyst data showing LoRa connections tracking well above NB-IoT on a global ex-China basis through 2030. Zenner alone accounts for 11 million deployed devices, mostly meters and sub-meters. Veolia has connected 4 million water meters. Actility manages 5 million. The Things Industries, 4 million more.

For Indian utilities wrestling with whether LoRaWAN is a proven technology or a promising experiment, those figures were the first and most important answer.

The Alliance also highlighted its formal recognition by the ITU as an international standard — a critical point for procurement officers in government-linked utilities who operate within certification and regulatory frameworks. The LoRaWAN Certified™ program, which provides device-level interoperability assurance, was presented as a procurement safeguard: certified devices from any vendor work with any compliant network, eliminating vendor lock-in.

The ecosystem value chain presented covered every layer a utility would need: Semtech as the chip and silicon foundation, Ripple as the device maker providing smart water meters, Kerlink as the gateway and network infrastructure provider, and open choice for building a private network, or using a public network operator like TATA Communications in India. The message to utilities: you do not need to integrate a technology stack from scratch. The supply chain is assembled, proven, and present in India.

Ripple Smart Metering: Building India's LoRaWAN Water Meter Reference

The most operationally grounded presentation came from Ripple Metering, an Indian company that has positioned itself as the country's leading LoRaWAN-native ultrasonic water meter manufacturer.

Ripple's product architecture is deliberately multi-protocol. The meter supports LoRaWAN (868/915 MHz, license-free), NB-IoT, 4G LTE-M, 2G GSM, and Wi-Fi in a single hardware platform. This is not a trivial design choice: it addresses one of the most common objections to LoRaWAN in emerging market utility tenders, where procurement committees frequently ask whether cellular fallback is possible. Ripple's answer is that the fallback is built in, and the utility chooses which connectivity to activate — or can switch without replacing the meter.

The operating principle used is Time of Flight (TOF) ultrasonic measurement — the same approach that dominates European smart water metering markets. Two transducers transmit ultrasonic pulses in opposite directions through the flow; the difference in travel time is directly proportional to flow velocity, and volume is computed by integrating flow rate over time. The advantages over mechanical positive-displacement meters are well-established: no moving parts to wear out, higher accuracy at low flow rates, longer service life, and resistance to turbidity and scale build-up.

Ripple's meters are certified to IP-68 — tested under IEC 60529 to withstand 1.5 metres of water immersion for four hours. This is not optional for Indian field conditions. The installation photos presented at the conference documented meters deployed in flooded pit chambers in Indian cities, with standing water around the meter body. IP-68 is the floor, not a premium feature.

Performance certification has been conducted by the FCRI (Fluid Control Research Institute), an Indian government-affiliated testing authority. The FCRI reports shared at the conference documented pass results across pressure tightness tests, pressure loss tests, resolution error tests, and metering accuracy tests per ISO 4064-1:2014 and ISO 4064-2:2014 standards. Covering pipe sizes from 15 mm to 40 mm (threaded) and up to DN50 and beyond (flanged), Ripple has addressed both household meter and district metering applications.

Field deployment photography showed installations spanning horizontal and vertical orientations in residential complexes, underground pit chambers, and bulk metering nodes. Remote rural installations were also documented — a point relevant for JJM rural tap connections, where manual meter reading is currently economically unviable.

The Ripple IoT backend — a full MDMS (Meter Data Management System) and HES (Head End System) built on Google Cloud — was demonstrated in live dashboard screenshots. The platform showed 30,853 total meters under management across 61 active projects, 23 active gateways, and 14,746 residential units monitored. A data table showed 5.5 million IoT readings stored and accessible. For utilities accustomed to quarterly manual reads, the proposition is not incremental improvement — it is a fundamentally different operating model.

Kerlink: The Gateway Infrastructure Layer

Kerlink presented its role as the network infrastructure layer in the LoRaWAN stack for smart water applications. The French company, one of the founding members of the LoRa Alliance and a pioneer of industrial-grade LoRaWAN gateways, has been deployed in India — with field photography showing a Kerlink gateway installed on a rooftop in an Indian city, antenna mounted on a pole with solar panels visible across the skyline.

The Kerlink gateway proposition is built on three attributes that resonate strongly in utility procurement contexts: manufacturing quality ("Designed and manufactured in France"), operational reliability (a 0.1% average product failure rate and lifetime guarantee on hardware), and deployment simplicity ("Plug–Connect–Deploy," with provisioning completed in under five minutes).

For a water utility deploying gateways across a city — some on rooftops, some on water towers, some on distribution station buildings — the ability to provision a gateway in under five minutes with no on-site engineering expertise is economically significant. It reduces truck roll costs, eliminates specialist installer requirements, and accelerates time to connectivity for new meter zones.

Kerlink's multi-connectivity gateway architecture also supports 4G LTE, LTE-M, and Kinéis satellite backhaul using Edge Computing alongside LoRaWAN, meaning that even in locations where wired or 4G backhaul is unavailable, the gateway can relay data via satellite link using LoRa. For rural JJM deployments covering areas with limited cellular infrastructure, this is not a theoretical edge case but a practical deployment scenario.

The Technology Comparison: Why LoRaWAN Beats NB-IoT and GSM for Water Metering

One of the most analytically detailed slides in the LoRa Alliance presentation was a direct comparison of LoRaWAN versus NB-IoT and GSM across eight technical and commercial dimensions. For conference attendees — many of them procurement engineers and utility executives evaluating technology options — this comparison was arguably the most decision-relevant content of the session.

The comparison covered network ownership, deployment flexibility, rural/remote coverage, power consumption, battery life, device and network cost, scalability, and latency. LoRaWAN was rated superior on network ownership (you own and control it, with no dependency on an operator), deployment flexibility (gateways can be placed anywhere, no coverage negotiation required), power consumption (very low versus NB-IoT's low-to-moderate and GSM's high), battery life (10+ years versus 5–7 for NB-IoT and 2–4 for GSM), device and network cost (no SIM card, no subscription, low infrastructure unit cost), and scalability (thousands of nodes per gateway, compared to NB-IoT's moderate and GSM's limited).

The strategic implication for India is particularly pointed. NB-IoT's coverage outside major urban centres remains limited and operator-dependent. GSM's 2G sunset risk — already materialising in several markets — makes it a poor long-term choice for devices expected to operate for 10 to 15 years in the field. LoRaWAN, with its license-free spectrum operation, private network capability, and sub-GHz propagation characteristics, can reach meters in basement pit chambers, underground vaults, and rural locations that cellular networks either do not cover or cover inadequately.

For India specifically, the ability to build a private LoRaWAN network — owned and operated by the utility itself — is a sovereignty and operational resilience argument as much as a cost argument. A utility that owns its network is not subject to operator pricing changes, coverage decisions, or service discontinuation. This matters enormously for long-term infrastructure investment planning in the public sector.

The Conference Intelligence: What Indian Utilities Revealed

The conference notes gathered alongside the LoRa Alliance presentations paint a picture of utilities at very different stages of digital maturity — and reveal where the most actionable LoRaWAN opportunities lie.

Bangalore (BWSSB) emerged as the most advanced and most significant reference case. BWSSB has already deployed a pilot LoRaWAN for AMI/AMR metering and presented their positive experience at the conference as a live endorsement of the technology. Their NRW target reduction from 27% is supported by AMI data that allows zone-level leak detection — something that manual reading cannot provide. At a water tariff of ~52 rupees per kilolitre for households and with treated sewage available at 25 rupees per KLD compared to ~99 rupees per KLD for fresh water for Commercial and industrial (C&I) use, the economic case for network-level leak reduction and water reuse visibility is straightforward.

Delhi Jal Board is pursuing a Digital Twin initiative for its 25 million population network spanning 15,000 kilometres of pipelines. With approximately 4 million water meters already in place and 30% of supply classified as NRW (representing 1,000 MLD of leakage), the Digital Twin programme requires dense sensor infrastructure to be meaningful — which is precisely the deployment scenario LoRaWAN was engineered for. Smart valves for tanker filling stations are being deployed, and pressure monitoring across the distribution network is on the roadmap.

Mumbai (BMC) presented the starkest problem statement: overflow from 4,000 kilometres of pipelines with no automatic cutoff is generating massive unbilled water losses. The technical path forward — leak detection sensors, pressure monitors, and smart valve control — maps directly onto the LoRaWAN sensor portfolio. Helium gas is currently being used to trace pipe leaks, an expensive and slow manual process that acoustic or pressure-based LoRaWAN sensors could complement at far lower per-detection cost.

The STP ecosystem deserves specific attention as an emerging LoRaWAN market. With 4,780 STPs planned under Swachh Bharat Mission 2.0, remote operational monitoring of flow rates, effluent quality, sludge levels, and biogas output represents a large and underserved IoT application. STP installations are often in peri-urban and rural areas where cellular coverage is unreliable, making LoRaWAN's private network capability a natural fit. The conference notes explicitly identified STP monitoring as a direct opportunity for low-power LoRa sensors.

Digital pipeline mapping was raised multiple times across sessions, including by Ministry of Communications representatives working on BharatNet 3.0. The inability to locate existing underground infrastructure before excavation is a major operational and economic problem. LoRa-enabled acoustic leak detection sensors, pressure monitoring nodes, and flow measurement points along distribution mains would provide the data layer that current pipe management systems lack. With AMRUT 1.0 targeting 6.5 lakh kilometres of water pipeline and 35,000 kilometres of drain pipeline by the end of the decade, the asset monitoring opportunity is vast.

SEBI's ESG water audit mandate for listed companies — requiring annual water audits — was identified at the conference as creating a new commercial demand category for LoRaWAN monitoring: corporate water accountability. Industrial facilities, data centres (where Hyderabad alone faces a 909 MLD shortage driven partly by cooling needs), and commercial buildings now have a regulatory driver to instrument their water consumption. This is a B2B market that operates outside utility procurement cycles and can move faster.

France as a Global Benchmark: What India Can Replicate

One of the most persuasive contextual arguments presented by the LoRa Alliance was the French deployment record. Over 3.6 million LoRa-based water meters have been installed in France by VEOLIA, connected to LoRaWAN networks and delivering measurable operational outcomes. The headline result: over 4 million cubic metres of clean water saved per year, through reduced water loss, faster leak detection, and optimised operations.

France's experience is directly relevant to India for three reasons. First, the technology is identical — the same LoRaWAN standard, the same frequency band principles, the same device certification programme. Second, the deployment model — a mix of public utility networks and private operator networks, covering both urban and peri-urban areas — closely mirrors what India is now developing through JJM and AMRUT. Third, the benefit categories — NRW reduction, operational cost reduction, customer billing accuracy — are the same problems Indian utilities are trying to solve.

The European sub-metering context is equally instructive. Over 10 million LoRa-based devices covering water meters, heating sensors, smoke detectors, humidity monitors, and CO₂ sensors are connected in European residential buildings, with 90% of those devices being meters. The market was catalysed by the European Energy Efficiency Directive's remote reading requirement. India's SEBI water audit mandate may play a similar catalytic role in the commercial segment.

The LoRaWAN Case for India's Water Sector

Synthesising the LoRa Alliance presentations and the conference intelligence gathered across both days, eight findings stand out as strategically decisive for the adoption of LoRaWAN in India's water sector:

1. NRW reduction is the highest-return first use case. Every city presented losses between 27% and 52%. At Indian water tariffs and distribution volumes, even a 10-percentage-point NRW reduction generates significant recoverable revenue and deferred capital expenditure on new water sources. AMI metering is the enabling layer.

2. Private network ownership is the right model for Indian utilities. The ability to deploy gateways on water towers, pump stations, and STP buildings — without any operator dependency — is not just a cost advantage. It is an operational control argument that resonates with public sector infrastructure owners.

3. The ecosystem is complete. From silicon (Semtech) through devices (Ripple), gateways (Kerlink), network servers (Orbiwise, Netmore, Loriot, AWS, Chirpstack, etc.), and public network operations (Tata Communications), every element of the LoRaWAN value chain is represented in India with commercially available products. Integration is feasible at utility scale today.

4. STP monitoring is the next major opportunity. With 4,780 facilities planned and most in areas with poor cellular coverage, LoRaWAN's low-power, long-range, private-network characteristics are a better architectural fit than any cellular alternative.

5. Digital pipeline mapping and leak detection are underpenetrated. The conference surfaced strong institutional demand — from Delhi Jal Board, from BMC, from Ministry of Communications — for infrastructure digitisation. LoRa acoustic and pressure sensors are commercially ready for this application.

6. SEBI's ESG mandate opens a commercial market. Corporate water monitoring does not require utility procurement timelines. It creates a new channel for LoRaWAN solution providers to address, potentially moving faster than the institutional utility market.

7. The urgency is real. India's water per capita will fall below the stress threshold by 2050. The deployment of smart monitoring infrastructure is not a long-term optimisation — it is a time-critical intervention in a deteriorating resource system.

Conclusion: Infrastructure That India Cannot Afford to Delay

The "Water in India" conference in New Delhi was not primarily a technology event. It was a water crisis event. Policymakers, engineers, utility managers, and technology providers sat together in recognition that India's water challenge is outpacing the pace of institutional response.

What the LoRa Alliance presentations demonstrated is that the technology gap is already closed. LoRaWAN is deployed at scale in India. It is certified. It is supported by a 350-member global ecosystem. It performs in the field conditions that Indian utilities actually face — flooded pit chambers, remote rural installations, dense urban environments with signal interference. It costs less to operate than any cellular alternative, owns no subscription dependency, and generates the granular, continuous consumption and leakage data that makes modern water network management possible.

The distance between India's current water infrastructure and what it needs to be is large. But the distance between where LoRaWAN is today and where Indian utilities need it to be is not. The technology is ready. The supply chain is ready. The reference deployments exist. The regulatory environment — through JJM, AMRUT, MOHUA standards, and SEBI audit mandates — is moving in the right direction.

What the conference made clear, above all, is that the time for pilots and proofs of concept has passed. India's water crisis demands deployment at scale, and LoRaWAN is the connectivity infrastructure that makes that deployment viable.

This article is based on presentations delivered by LoRa Alliance members at the "Water in India" conference, New Delhi, April 28–29, 2026, and on conference intelligence compiled by Semtech during both days of the event. Member companies presenting included Semtech, Ripple Metering and Kerlink.
