Sanitary Sewer Overflows – Is There a Solution?

USST’s See, Clean, & VerifyTM Services Save Time and Money Sanitary Sewer Overflows – Is There a Solution?  Yes, especially if the overflow is caused by an obstruction.   When working with a customer who is facing issues with sanitary sewer overflow (SSO) U.S. Submergent Technologies (USST) first tries to understand the problem.  At USST, our experience has been that every sewer pipeline system is unique and collects debris differently and gaining visibility into the pipeline is the first step.  Recently, a county in Southwest Florida was at risk of SSO from their large diameter sanitary sewer pipeline, which encompassed over 15,000 feet.  USST was called in to perform our See, Clean, & VerifyTM services using our combined CCTV crawler and sonar imaging to inspect or see where accumulation was occurring and perform an inspection of surcharged lines.  “We went in and conducted a full inspection and met with the county to review our pre-cleaning report, which targeted areas of their sanitary sewer line that were of greatest concern with a high accumulation of sand and grit,” said Aaron Hood, Operations Manager at USST. “Working with the county, we established a targeted plan for 2,000 of the 15,000 feet of large-diameter … Read More

Facility Remains in Full Operation While Cleaned

Capacity Restored in Charlotte County The Burnt Store Water Reclamation Facility (WRF) treats wastewater from more than 1,200 sewer connections in a southeastern portion of Charlotte County.  Acquired by Charlotte County in 2003, the former 0.25 millions of gallons per day (MGD) facility underwent several upgrades, including doubling its treatment capacity to 0.5 MGD, as well as enabling the facility to simultaneously dispose of reject water and excess effluent produced by the plant.   USST removed 21-cubic yards of sand and grit from three structures at Charlotte County’s Burnt Store WRF.  Thanks to our GritGone Process®, the facility remained in full operation while the debris was removed. John Thompson Jr., Chief Plant Operator at the Burnt Store WRF says, “The project that U.S. Submergent did for us was wonderful.  They not only helped with our grant application, but their crews were very accommodating and […] professional.” Accessing particularly tall tanks, like Burnt Store’s 30(+)-foot EQ tank, can be challenging.  Luckily, our Combination3® trucks are equipped with a 49-foot knuckle boom crane with telescoping tubes.  This eliminated the need for additional equipment on the jobsite, saving the facility valuable time and money.

Energy Savings Through the GritGone Process

US SubmergentGritGone Process®Leave a Comment

Cleaning your tanks is not only important to restore capacity, but it also has potential to save on energy, which cuts costs down the road. Sand and grit is a heavy solid with a specific gravity greater than 1, so it accumulates and settles to the bottom of the tanks. The system then has to work harder to keep the sand suspended and allow oxygen to flow through the system to treat the water. Over time, this can drastically increase costs and detention times. U.S. Submergent Technologies recently conducted an energy analysis for a facility that used the GritGone Process® for residuals and debris removal. We found that in this particular instance, our customer is able to recoup their costs for our sand and grit removal service in energy savings in approximately less than two weeks.

Introducing the USST 1249 Combination³® Truck

US SubmergentCombination³® TruckLeave a Comment

U.S. Submergent Technologies, developer of the innovative and powerful Combination³® technology, introduces the model 1249, a medium-size model in its line of combination trucks. Designed to clean wastewater treatment plants and large diameter pipes, the 1249 will begin service in Florida this month. USST’s Combination³® technology earns its distinction by featuring three components: vacuum, jetter, and a downhole system. The downhole system allows equipment to clean in deep or submerged environments and remove high viscosity material. The entire service can be performed while the plant remains in full operation – a capability that was previously missing in the vacuum truck marketplace. Technical features of the model 1249 include: ·      49-foot knuckle boom crane with telescoping tubes for hard-to-reach places ·      400-horsepower engine that fully powers the Combination³® components ·      Fully automated, multi-directional reel capable of holding up to 1,000 feet of jetter hose ·      Downhole system that enables the removal of debris from deep or submerged conditions, or the removal of high viscosity fluids ·      Includes mounted vacuum system for use as required ·      Jetter nozzle produces 180 gallons per minute at 2,000 psi ·      12-yard debris tank, highly pressurized for debris and water separation U.S. Submergent Technologies Combination³® equipment is operated remotely, saving time … Read More

What’s in the Tank?

US SubmergentGritGone Process®, USST newsLeave a Comment

U.S. Submergent Technologies boasts its ability to remove sand and grit while the plant remains in full operation, and our equipment has a proven success track to back this claim. But what if we aren’t talking about sand and grit? Let’s take a look at what other materials can be settled at the bottom of the tank and how the GritGone Process® can handle them. The types of material found at the bottom of the tank varies depending on which stage it is in the wastewater treatment process. For example, in the anaerobic zone, the accumulated material may not be only sand, but it could also be biosolids, depending on the process and how much time has passed since the last cleaning. The GritGone Process® can remove material that has specific gravity values greater than water. The specific gravity of biosolids is less than water, but sand, grit and other accumulated materials have a specific gravity greater than water. Can the GritGone Process® Remove Biosolids too? The GritGone Process® removes nearly all accumulated material at the bottom of a structure using our proprietary downhole system. Through our process, pressure separates the material with a specific gravity greater than water from … Read More
