History

OneRain Company Overview

OneRain Inc. was started in 1992 as DIAD Inc. to integrate automated, telemetered monitoring stations and provide software for collecting real-time environmental data. In 2003, DIAD acquired NEXRAIN in order to increase the accuracy of rainfall estimates by using rain gauge data to calibrate NEXRAD data. At that time the company name became OneRain.

Since its inception, OneRain has provided rainfall and related environmental information for agencies with critical missions. Today, OneRain’s offerings include nationwide, 24/7-supported enterprise data collection, archiving, notification and web visualization services. Our products include local data collection software, telemetry system integration, rain and other hydrometeorological gauging and professional services, real-time satellite and IP telemetry services, gauge-adjusted radar-rainfall estimates, storm properties analyses and consulting services.

Today, OneRain is the industry-leading provider of real-time and historical rainfall-related data and professional services to local, state and federal government agencies across the country. Application areas include flood warning, reservoir operations, dam safety programs, wastewater and stormwater collection, planning, modeling, and forensic analyses. The market for OneRain’s services continues to grow, as understanding rainfall and its consequences is becoming increasingly critical in the 21st century to protecting our global fresh water resources. Our focus on rainfall outcomes, hydrologic monitoring and robust information networks allows us to provide high quality information and software products to agencies with critical, high-value water resource management missions. We are the only company in this domain to offer a 24/7-supported hosted data enterprise that is integrated with agencies’ local base station software for mission-critical use.
