We clean tanks in operation, with no confined space entry required


Cleaning tanks in submerged conditions while in operation is our specialty. If the infrastructure allows, we can clean tanks while in service, without the need to drain down structures, which keeps our crew out of confined space and allows us to solve problems that were previously very expensive to solve. 

Tank depth and wall height are common constraints when it comes to removing sand and grit from tanks, chambers, basins, and more. If you’re facing high walls, we’ve got you covered. With the extended reach of our Combination3® equipment, even in drain down or dry conditions, we are able to achieve a high rate of production and can reach where others can’t.

Your obstacle

There are many types of tank structures used in a variety of ways in wastewater treatment systems, and they can all experience reduced capacity from the gradual accumulation of sand, grit, FOGs, rag material, vegetation, and more. Buildup of these types of material leads to increased energy costs and reduces overall plant efficiency. 

Our Solution

U.S. Submergent Technologies cleans tanks in operation with no confined space entry required whenever possible. We can provide regular maintenance so facilities can avoid performing costly repairs or replacing expensive infrastructure. In addition, when cleaning in wet environments, our patented GritGone Process® results in paint-filter dry material, ready for disposal.

Being able to reach and remove what others can’t is our specialty.
