Our Story

EnviroEye founder Mark Rauch has owned and operated pipeline and storage tank facilities for more than 30 years. Through that experience, he saw firsthand one of the persistent challenges of external floating roof tanks: managing rainwater runoff while preventing contamination from product leaks or spills.

Most floating roof tanks rely on drain systems to remove accumulated rainwater, but those systems introduce risk. Operators must monitor weather conditions and manually manage drain valves, creating opportunities for human error and undetected releases.

Working with long-time industry partners, Mark developed a solution that removes the need for continuous on-site monitoring. The Floating Roof Drain Guard System uses hydrocarbon detection sensors to identify the presence of oil or related chemicals in the drain system. When contamination is detected, the system immediately alerts personnel via cellular or email notifications and can automatically close the drain valve.

By automating detection, notification, and valve control, the system reduces reliance on manual oversight and helps prevent undetected spills, environmental impact, and operational risk.

EnviroEye Minimizes Your Risk 

The EnviroEye Floating Roof Drain Guard System continuously monitors drain flow for hydrocarbons at a sensitivity level you define. When hydrocarbons are detected, the system automatically closes the valve to isolate the drain—preventing the release of tank contents before a discharge can occur. At the same time, EnviroEye issues a customized alert to notify operators immediately.

“In more than 27 years of owning and operating pipeline and terminal facilities, one issue remained unresolved: how to manage floating roof drain valves without accepting unnecessary risk. Leaving them open or closed both carried consequences.  After years of searching for a workable solution and finding none, we developed one ourselves. The Floating Roof Drain Guard System has proven effective in real-world operation—improving efficiency, reducing risk, protecting capital investments, and safeguarding the environment”

EnviroEye Provides Peace of Mind 
Its innovative technology allows roof drains to be safely left open–a viable solution.

“At our facility, we keep floating roof drains open to manage unpredictable severe weather. That decision reduces one risk, but it introduces another—the potential for a product release if a roof drain failure occurs.  EnviroEye eliminates that vulnerability by continuously monitoring the drain and automatically closing the valve if product is detected. As terminal manager, I sleep better knowing EnviroEye is protecting the facility 24 hours a day, seven days a week.”
