    A Word From Our Customers

    As a head wastewater operator for a city with multiple remote lift station locations, I have looked into multiple options for communication of these sites. I can attest that RDI's TankVitals Solutions is by far an option that can't be beat! At a fraction of the price of radio and fiber systems, this cellular is not only affordable, but superior in reliability. Combine that with customer service that is in my opinion the best in the industry. I couldn't be happier with this system. I wouldn't hesitate to recommend this to any municipality that is looking for quality, affordability, and reliability.
