Over 4,800 Feet of Large Diameter Pipe Cleaned and Inspected While in Operation

In Central Florida, U.S. Submergent Technologies (USST) cleaned and inspected over 1,900 linear feet of 36” pipe and 2,800 linear feet of 48” pipe. Our patented and versatile Combination Truck allowed USST to clean these large diameter pipes while they remained in service, with no need for bypass or shutdown.

Using See, Clean, & Verify, U.S. Submergent Technologies’ crew removed 276 tons of sand and grit while remaining in operation.

During the 2020 rainy season, pipe systems were put to the test with additional flows from rainfall. This stretch of pipe was along a major thoroughfare and could not be taken out of service which presented unique challenges that only USST’s patented technology could resolve. Using our phased approach of See, Clean, & VerifyTM, 276 tons of sand and grit were removed while remaining in operation. Our SediVisionTM technology allowed USST’s crew to provide a post-cleaning inspection and verify for the customer that their pipe capacity was fully restored.


“When going into a job like this safety is our number one priority. Through extensive and ongoing training, the principle of safety is embedded into the function of every single crew member,” said Aaron Hood, Operations Manager at USST. “Our experience and dependability made for a winning combination with this challenge, and we were happy to meet it head-on, resolving this customer’s pipe capacity issues and restoring optimal flow.”


USST’s Combination Trucks are so much more than basic vacuum trucks.  Equipped with a powerful vacuum, downhole pump, jetter, and extended-reach boom, they can clean in wet or dry conditions in up to eight different setups without bringing multiple pieces of equipment to the job site. While on the job, USST crews can cycle roll-off trucks and steadily remove material, with no need to stop work, ultimately saving time and increasing efficiency.
