Removing a 30,000-gallon underground storage tank is never simple, especially when it’s partially enclosed in a concrete vault and filled with high-viscosity No. 6 fuel oil.

In this project, our team implemented specialized solutions, including a multi-stage removal process to handle the tank’s unique location.

This tank removal highlights the importance of experience and precision in complex projects.

When a Decommissioned Tank Still Needs Attention

Not all underground storage tanks can be removed safely, especially in dense, historic areas. In this Boston project, voids were found in the concrete fill of a tank that had been closed-in-place.

CommTank performed targeted repairs to stabilize the tank, eliminate structural concerns, and bring the system back into compliance, all without risking damage to surrounding buildings.

Behind every hospital’s emergency power system is reliable fuel infrastructure.
CommTank completed a complex underground storage tank replacement at St. Joseph Hospital & Trauma Center in Nashua, NH, removing aging tanks and installing a new 20,000-gallon UST. To protect critical operations, a temporary fuel system was used during excavation, testing, and system upgrades.

The project wrapped up with full site and asphalt restoration, leaving the facility safe, compliant, and ready for long-term operation.
