Sensors mounted on the covers detect events such as unauthorized openings, abnormal gas levels, and temperature anomalies, enabling early warning and safer network operations.
THE PROBLEM
The blind spots are underground
Manholes are where collection-system issues surface, often after the damage is done. Manual checks are slow, inconsistent, and risky.
Continuity gaps
Cellular dead zones and power disruptions interrupt monitoring, creating data loss at critical times.
Costly reactive operations
Fixing issues after they escalate drives higher OPEX, more truck rolls, and greater field safety exposure.
Weak incident traceability
Without timely, timestamped event evidence, reporting and root-cause analysis become slower and less reliable.
Unseen security breaches
Unauthorized entry and tampering can remain undetected, increasing public safety and infrastructure risk.
VALUE AT A GLANCE
Evidence Grade Event Logs
Space-powered delivery keeps data moving when terrestrial networks fail.
THE SOLUTIONS
Built for Underground Reality
Plan-S delivers an end-to-end, event-driven monitoring layer for sewer manhole covers. Sensors detect opening and abnormal condition changes, while compact Connecta IoT Modems transmit those signals through the Connecta IoT Network.
Sense at the cover
Sensors attached to sewer manhole covers detect events such as unauthorized opening and temperature variations.
Connect with Connecta IoT Modems
Compact, field-ready modems collect and package sensor signals for dependable delivery.
Transmit via the Connecta IoT Network
Data is sent through Connecta IoT Network satellites, creating a resilient stream from street level to space, without relying on local terrestrial infrastructure.
Operate from a single monitoring layer
Signals appear in the central monitoring platform with clear status visibility and event timelines.
Trigger response
Instant alerts reach municipalities and public utility teams so they can act quickly, prevent accidents, and coordinate field interventions.
