Hydro Radar, LLC

Hydro Radar, LLC, founded in 2021, develops radar-based monitoring systems for sewer and stormwater infrastructure. The company adapts automotive-grade mmWave radar technology for above-flow level and flow measurement in municipal collection systems, positioned as a lower-cost, higher-density alternative to ultrasonic in-flow sensors and legacy 24 GHz radar instruments. The HydroRadar sensor mounts above the channel, eliminating confined space entry during installation, and uses vibration-isolation hardware with quick-change battery access for simplified maintenance. Data transmits via CatM cellular connectivity with satellite failover, storing readings with unlimited cloud storage. The platform's AI-driven dashboard validates detected anomalies across a network of deployed sensors, delivering near-real-time alerts for potential blockages, capacity constraints, and overflow events before they escalate. Hydro Radar completed a pilot deployment with the City of San Francisco in 2022, which reported reduced overflow incidents, and a separate evaluation with the U.S. Environmental Protection Agency in 2023. The company offers a free pilot program for municipalities evaluating network-wide deployment across their sewer and stormwater systems. Specific model numbers, measurement accuracy ranges, and detailed technical specifications are not published on the company's website.
