2025 CASE STUDY Case Study: How Smart Metering Cut Water Usage by 30% in Húsafell, Iceland ABOUT THE PROJECT Client: Utility, Ferdathjonustan Húsafelli ehf. Scope: 233 single-family households Project Duration: One year THE CHALLENGE Until recently, Húsafell's district heating and water distribution system was billed on a flat fee basis with no individual metering. This created several challenges: • Excessive Water Use: Residents had little incentive to conserve water resources, driving up overall consumption as a result. • System Overload: High usage caused frequent pressure drops across the network. • Growing Investment Needs: Over consumption pushed the utility toward costly infrastructure upgrades. THE SOLUTION • 233 Ultrasonic Water Meters installed in single-family households • 1 Kerlink Outdoor Gateway for LoRaWAN ® for full coverage across the community • Mainlink Data Management Platform enabling billing exports, leak and burst detection, and network monitoring • Resident Mobile App providing daily usage visibility, consumption comparisons, and instant alerts RESULTS & BENEFITS 1. REDUCED CONSUMPTION • Overall water usage dropped by at least 30% after smart metering installation. • Pipe bursts were detected in the early stage, preventing losses and damage. 2. LOWER INFRASTRUCTURE COSTS • Accurate water monitoring reduced the need for new pumping stations, long transmission pipelines, and additional wells - saving capital investment. 3. IMPROVED RESIDENT EXPERIENCE • Fewer complaints: Pressure-drop issues caused by network overload were significantly reduced. • Residents gained real-time visibility of usage through the mobile app, increasing trust and satisfaction. 4. OPERATIONAL EFFICIENCY • Transparent billing with accurate consumption data • Remote monitoring reduced the need for site visits • Custom alerts for leaks, burst pipes, and unusual consumption behavior improved response times. WHY MAINLINK & AXIOMA SOLUTION The Axioma-Mainlink smart metering solution was a perfect fit for our distribution system providing excellent user interface for monitoring and billing with low implementation cost compared to other solutions' — Arnar Bergthorsson, IT and Digitalization Specialist.
