HWM-Water

What HWM-Water does

HWM Global (legal entity HWM-Water Limited, formerly HWM-Water) designs, manufactures, and supports monitoring and telemetry equipment for water, wastewater, and gas networks. Founded in 1979 as Reten Acoustics (inventor of the world's first leak noise correlator) and operating today as a wholly owned subsidiary of Halma PLC, the company is headquartered in Cwmbran, United Kingdom, with a US operating entity (Fluid Conservation Systems) and channel partners across 50+ countries. Its portfolio spans acoustic leak detection loggers (PermaNet SU, PermaNet+, PermaNet TM GPS, SoµndSens), multi-parameter data loggers (MultiLog 2, MultiLog LX2, MultiLog IS, IS Log, Intelligens WW), pressure management systems (Pegasus 2, Sentinel 2, Pressure Transient logger), wastewater sensors (SpillSens, RadarSens, SonicSens 3), and digital ground microphones (DXmic Pro, Touch Pro).

The technical architecture centers on the DataGate cloud platform, which aggregates, analyses, and visualises data from over 100,000 deployed loggers globally and powers sub-platforms DataView (fleet visualisation), PermaNet Web (leak detection correlation), PressView (pressure control), and SpillGuard (wastewater monitoring). Machine learning algorithms trained on the largest global leak dataset drive anomaly detection and false-positive reduction in acoustic analysis. The business model combines hardware product sales with a growing cloud/SaaS software layer (DataGate), training services at the Grainger Training Facility (2,000+ technicians trained), and ongoing technical support and service. Go-to-market is hybrid: direct enterprise sales with regional and key account managers for major utility clients, complemented by an extensive channel partner network (AxFlow AS, ACG Envirocan, Bio Mass Impianti SRL, Aqua Mesure, FCS) and an inside-sales operation handling enquiries, customer service, and service support.

Primary customers are water utilities (clean and wastewater) in the UK, Europe, the Middle East, Africa, Asia, and the Americas, with secondary exposure to industrial facilities (e.g., Wanhua Chemical). Certifications across MCERTS, ATEX, IECEx, CE/UKCA, FCC, IP68, KC, and ISO 9001/14001/27001/45001, plus Cyber Essentials and Achilles, support procurement into regulated utility and hazardous environments.

Core offering

HWM-Water (trading as HWM Global) designs and manufactures monitoring and telemetry equipment for water, wastewater, and gas networks. Its portfolio includes acoustic leak detection loggers (PermaNet+ SU, PermaNet+, PermaNet TM GPS, SoµndSens), data loggers (MultiLog 2, MultiLog LX2, MultiLog IS), pressure control systems (Pegasus 2, Sentinel 2, Pressure Transient), and wastewater sensors (SpillSens, RadarSens, SonicSens 3), all connected through the DataGate cloud-based data management platform.

Product overview

HWM Global offers a unified portfolio of water and wastewater network monitoring solutions built around the DataGate cloud platform. The core offering comprises acoustic leak detection systems (PermaNet+ SU, PermaNet+, PermaNet TM GPS, SoµndSens), data loggers (MultiLog 2, MultiLog LX2, MultiLog IS, IS Log, Intelligens WW), pressure management solutions (Pegasus 2, Sentinel 2, Pressure Transient), and wastewater monitoring sensors (SpillSens, RadarSens, SonicSens 3). These are complemented by digital ground microphones (DXmic Pro) and leak noise correlators (Touch Pro). The DataGate platform serves as the central hub, with sub-platforms DataView for visualisation, PermaNet Web for leak correlation, PressView for pressure control, and SpillGuard for wastewater monitoring. The portfolio spans both above-ground (ground microphones, correlators) and below-ground (fixed acoustic loggers, sensors) monitoring for clean water and wastewater networks.

Direct peers

• Gutermann: Gutermann is a Switzerland/Germany-headquartered acoustic leak detection and zone measurement specialist. It competes directly with HWM's PermaNet, SoundSens and correlator product lines, sharing the same utility-NRW customer base and distribution through municipal tenders.
• SebaKMT (Megger Group): SebaKMT, now part of Megger, sells leak noise correlators, ground microphones and acoustic loggers overlapping HWM's Touch Pro, DXmic Pro and PermaNet+ lines. Both target water utilities globally and compete in the same tenders.
• Echologics (Mueller Water Products): Echologics is the acoustic leak detection and pipe-condition assessment division of Mueller Water Products. It directly overlaps HWM's fixed acoustic logger (PermaNet) and correlator portfolio, and is sold into the same North American municipal utility procurement cycles.
• Aquilar: Aquilar is a UK specialist in leak detection and water network monitoring equipment, directly overlapping HWM's PermaNet and ground-microphone offerings in UK water-utility tenders. Useful comparator for pricing and bundled solution positioning.

Broad incumbents

• Itron: Itron is a global smart water/AMI metering and analytics incumbent. While broader in scope, its pressure/flow sensor analytics and AMI communications modules increasingly overlap HWM's telemetry loggers and DataGate platform, particularly in North American municipal deployments.
• Mueller Water Products: Mueller Water Products is a broader water infrastructure incumbent covering valves, hydrants, smart meters and Echologics leak detection. Comparable to HWM on the leak-detection side and a potential acquirer/competitor for end-to-end monitoring contracts.
• Xylem (incl. Sensus): Xylem combines the Sensus smart-water AMI brand with utility analytics and supports pressure/transient management. It competes with HWM where utilities bundle metering, pressure control and leak detection under a single vendor contract.
• Badger Meter: Badger Meter is a leading North American AMR/AMI and flow metering manufacturer with overlapping pressure/flow data acquisition capabilities. Its BEACON SaaS platform is an analog to HWM's DataGate for networked utility monitoring.
• Kamstrup: Kamstrup is a Danish smart metering and energy/water utility solutions provider. Comparable in metering, AMR/AMI and analytics layers overlapping HWM's totalizing sensors and DataGate platform in Europe and global tenders.

Emerging players

• Radiodetection (SPX): Radiodetection, part of SPX Technologies, is best known for buried utility locating. Its acoustic and camera-based leak detection products compete with HWM's DXmic and Touch Pro lines and the company is also expanding into broader pipeline condition assessment.
