From Lime to Lawn Chairs: Materials We Remove from Pipes and Tanks

Sand and grit removed from oxidation ditch.

We’ve seen it all: sand, grit, sludge, lime buildup, vegetation, and even larger debris such as metal handrails and lawn chairs. U.S. Submergent Technologies can remove any type of material (yes, even lawn chairs!) from wet or dry environments in a variety of structures. 

We use the extremely versatile Combination3® Truck to specialize in removing material from structures such as pipes, tanks, and lift stations while they remain in full operation, and we can also perform work in a drain-down or bypass situation when larger debris is present.

A history of solving difficult problems

Debris removed from Stormwater Box Culvert.

U.S. Submergent Technologies has tackled unique situations, including heavy lime accumulation in a large biological treatment unit, resulting in the removal of 60-tons of lime, sand and grit. We’ve successfully cleaned a tank overrun with 4-foot high vegetation sitting on an 8-foot root system. The U.S. Submergent Technologies’ crew once developed a crane attachment to be used with the Combination3® Truck’s extendable boom to reach and remove difficult rag material — and even a metal handrail — from a splitter box. 

Our experienced crew removed wood and lawn chairs from a stormwater box culvert, as well as more traditional projects, like the removal of 402-tons of sand and grit from an oxidation ditch (without a drain-down) and navigating 7,000-feet of gravity sewer while in service.
