AI Flood Warning System Goes Live in Galveston County

An AI-powered flood warning system has gone live in Galveston County under a pilot agreement with Simplicity Integration LLC for smart water sensors, installation, maintenance and data services.

The system, first deployed in April, is intended to give responders and residents a real-time view of changing water conditions and support earlier, more targeted flood alerts. Axonis Decision Intelligence and Simplicity Integration announced Tuesday that the solution is now operating in Texas, with Galveston County serving as the first deployment site.

The agreement between the Galveston County Consolidated Drainage District and Simplicity, approved by the district board Sept. 9, 2025, covers smart water sensor purchase, installation, maintenance and data services.

The contract calls for eight sensors at a total initial cost of $49,500. The estimate included in the agreement lists four ClearView Contact-Free Kits at $8,000 each, three SafeFlow Starter Kits at $5,000 each, one additional SafeFlow Starter Kit at no charge, a $500 initial site visit fee and a $2,000 bridge mount customization fee.

Ongoing data services are priced at $23 per month per sensor, billed annually as $276 per sensor. Those services include communications through cellular, Wi-Fi or satellite, along with security, storage, reporting, analytics, backup, battery usage and alert management. The agreement also lists annual maintenance after the first year at $100 per sensor.

The flood intelligence solution, called SI-Ai, was designed by Simplicity and is powered by Axonis. According to the companies, it brings together live sensor readings, public weather and water-level data, historical trends and local infrastructure information into a single operational view.

The system can trigger alerts to responders and residents and can be configured to activate infrastructure such as sirens, warning lights and barriers. Alerts can be sent to an unlimited number of phone numbers or email addresses, while administrators control which alerts are sent to the public audience.

Implementation materials in the contract identify proposed deployment locations at Chigger Creek at Friendswood Trail, Chigger Creek at Oak Drive, Steven’s Park, Clear Creek, Mary’s Creek at Devil’s Dip, Mary’s Creek at Winding Road and Bakers Road at Cowards Creek. The materials include site photos and recommended installation approaches, including headwall mounts, adapted bridge or guardrail mounts and a tree-mounted gateway configuration at Steven’s Park.

Under the agreement, ownership of the physical sensors transfers to the drainage district after installation. Simplicity retains ownership of sensor data and aggregated data, while the district receives a license to use sensor data, customer data and aggregated data for internal purposes including flood mitigation, emergency management, public safety and other municipal functions.

“What’s been missing is a way to turn all the signals coming from the edge into something people can actually use in the moment,” said Alison Reese, chief operating officer and co-founder of Simplicity Integration, in a press release. “Communities already have sensors, weather data and infrastructure in place, but those pieces aren’t connected in a way that supports real-time decisions.”

Axonis said its technology brings AI directly to the data through a federated architecture, allowing analysis without moving sensitive data into centralized environments. The company described the system as built on a defense-grade security foundation for critical infrastructure settings.
