How ECHO Utility Engineering and Surveying Benefits From Using a Vacuum Excavator

ECHO Utility Engineering and Surveying focuses on a specific aspect of utility engineering: subsurface utility engineering.

Subsurface utility engineering refers to a branch of engineering that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, communication of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.

ECHO purchased a Vac-Tron Series AIR 373 SDT vacuum excavator in 2017 and shared the benefits this unit has created for the company.

Project description

Locating existing subsurface utilities data.


The Vac-Tron Series AIR 373 SDT vacuum excavator unit ECHO purchased with customized accessories is powered by an 83 hp Yanmar diesel engine that delivers unmatched power and performance. It’s hand-built in Florida from the ground up including the durable low profile I-Beam trailer assembly. The low-profile trailer keeps the components of the unit easily accessible while making the unit safe to tow and a much smoother ride. The AIR vacuum excavator comes equipped with a hydraulic rear door, which opens fully so the operator can completely empty the contents. For operator safety, the door is controlled by push buttons located on the side of the unit. This series also offers the patented filtration system with 0.5-micron filtration that is unmatched by competitors.


ECHO has been using the AIR series vacuum excavator for over two years now. The main efficiency has been getting into tight places and safely onto curbs with the low-profile unit.  “It allows us to get to projects that we normally wouldn’t be able to do,” says President of ECHO UES, Jerry Comellas. “One of the projects we worked on was in a covered garage and if it wasn’t for this unit there is no way we could have accomplished the project because of the low clearances. This was a $48,000 project and that is revenue that we wouldn’t have been able to have otherwise.” 

This Air Series also allows for air vacuum excavation, which is the process of using compressed air to disturb the earth’s soil which is then vacuumed up into a debris tank. Air excavation is used to safely expose underground utilities and allows backfill with the dry material.

“Vac-Tron’s customer service has been outstanding, getting us set up quickly, as our business works really fast, and catering to some of the refinements we made on the unit made it a pleasure to work with them,” Comellas says.
