In 2019 Unified was the first petroleum contactor in Iowa to install a completely secondarily contained system including under dispenser containments, underground piping, and tank top containments at a gas station in central Iowa. The team received on site training directly from the manufacturer to ensure the system was installed and operates exactly as the manufacturer intends.

In Fall 2019 Unified was invited to speak to all of Iowa's licensed installation companies during their annual training to share their experience and expertise on this new technology.

Unified continues to be the leaders in new and innovative technology. They find a system design that works best for the customer's needs and assists them with easily staying in compliance with state and federal regulations.
