Autonomous Water Infrastructure
An autonomous in-pipe capsule that detects and seals leaks in live water systems. No excavation. No service shutdown.
Municipal utilities worldwide spend over $180 billion annually on reactive maintenance and water loss management. Each traditional excavation repair costs $10,000–$15,000 and can consume half a rural district’s entire annual budget.
Traditional repairs require excavation, weeks of disruption, and a complete service shutdown. O-Seal fixes leaks for under $1,000 (dropping to $400 at scale), with zero service interruption.
O-Seal operates entirely within the pressurized pipe. No digging, no lane closures, no service interruption.
Onboard pressure sensors detect a leak signature, the capsule positions itself, and the seal deploys autonomously.
Lightweight capsules are inserted through existing access points and deployed in swarms to cover complex networks.
Pressure sensors sample hundreds of times per second. A physics-informed neural network differentiates a pipe crack from normal flow noise and pinpoints the breach location.
A CO² cartridge inflates the outer torus against the pipe wall in under one second. In bench testing the device retains 97% of water that would have escaped the breach.
Capsules coordinate via localized underwater acoustic modems — no cellular signal, no human intervention. A trio can seal three unknown breaches across 2 km in under 90 minutes.
