ManholeMetrics
About
ManholeMetrics manufactures radar-based level sensors and cloud analytics software for sewer collection system monitoring. The company's contact-free level sensor features IP68 rating, over 10 years of battery life, and LTE-M and NB-IoT cellular connectivity for deployment without wired infrastructure. Installation takes under 10 minutes with minimal tools, enabling rapid fleet-scale deployment across municipal networks. Measurement range spans 0.7 to 33 feet (0.2 to 10 meters). The accompanying Porthole cloud platform aggregates sensor, rainfall, and operational data providing live and historic level data, real-time and predictive flood alerts, maintenance and infiltration and inflow alerts, and fleet-wide device and alert management. ManholeMetrics has deployed systems across North American and UK utilities including Phoenix, Arizona, EBMUD in California, and Toronto Water in Canada, as well as Network Rail for UK national transport infrastructure. The platform serves operations teams, compliance and planning groups, asset managers, and hydraulic modelers. The sensor-to-cloud system targets proactive collection system management enabling utilities to detect blockages, quantify infiltration, and plan capital improvements from measured field data rather than estimates.
