Contrail® Customers

Contrail® is OneRain's real-time hydrometeorological data collection, analysis, dissemination and process management software platform for early warning and forecasting of floods, dam safety monitoring, water management and other hydrologic and environmental event-based alarming and notifications. Contrail supports hundreds of local, state and federal government agencies across U.S.A. 

Role-based Views

Contrail can be configured to meet the needs of many and different users. For example, the Flood Control group may need to see and act on very different information than the Stormwater group. Contrail is designed to enable different views and expose different information so that users can see what is relevant to them. Graphing, reports, alarms and action notifications can all be tailored to each individual department and the roles they play inside your organization.

The examples below show public-facing views of Contrail. What you won't see here is the powerful stuff that's going on behind the scenes in Contrail. Contact us today for a full demonstration.
