Barefoot Bay Advanced Wastewater Treatment Facility (AWWTF) was experiencing reduced plant capacity and due for maintenance on multiple structures as part of its rehabilitation plan for the facility.  Sand, grit, rags, and sludge had accumulated in the 0.9 MGD facility’s equalization tank as well as a 93-feet diameter multi-service tank.

Having different types of structures onsite often require different methods of cleaning to get the job done. U.S. Submergent Technologies’ (USST) Combination truck is more than just a vac truck.  Sporting a vacuum, downhole pump, jetter and extendable boom on one chassis, USST’s Combination trucks have the ability to clean in wet or dry conditions using multiple setups.

Getting the Job Done in Barefoot Bay

Paul Del Favero, one of USST’s veteran Field Supervisors, arrived with a team to the Barefoot Bay site prepared to remove material from the two structures using two separate methods of removal with one, unique piece of equipment.  The crew used the Combination truck’s extended boom and downhole pump to safely and efficiently remove 16-tons of sand and grit from the facility’s multi-service tank which remained in full operation throughout the project. 

Due to the extended reach capabilities of the Combination truck, confined space entry was not needed to clean the multi-service tank. THis made it safer for the onsite crew and limited costs for the client.  The truck’s vacuum capabilities were then utilized to remove nearly 91-tons of material from the facility’s equalization tank. 

“Using our Combination truck and GritGone Process®, we were able to remove sand and grit from the multi-service tank while the plant remained in full operation, then switch to vacuum to clean the equalizer tank, for a total of 106-tons removed,” said Paul.  “The versatility of our equipment provides us with valuable options and our exceptional crew got the job done quickly and safely.”

“When our technology helps facilities extend the life of their infrastructure safely and more efficiently, everyone wins,” said USST’s CEO, Denver Stutler, Jr.

Specializing in grit removal and restoring capacity to hard-to-reach environments in submerged conditions, USST can build a plan to safely and efficiently remove material from tanks, pipes, lift stations, and more.  Check out our video to learn more about the Combination technology and the GritGone Process®, and give one of our representatives a call for a free site assessment at (844) 765-7866.
