350 Tons of Material Removed from Basins in Central Florida

February 28, 2022
A Challenging Environment Calls for Skillful Pros In Central Florida, a 12 MGD reclamation facility was experiencing a loss of capacity in their north aeration and anoxic basins.  These tanks presented a challenge because they were lined with rows of diffusers that circulate oxygen feeding the microorganisms and bacteria residents that break down the waste.  This job required experienced professionals to access and remove the built-up material, so the customer called on U.S. Submergent Technologies (USST) for a solution.  USST has cleaned tanks, pipes, and lift stations on over 400 projects around the United States.  Our qualified crews know how to evaluate situations on the ground to get the job done safely and efficiently. “I am proud of our guys for navigating the hard-to-reach environment along the bottom of these tanks and capably removing large amounts of material,” said Eric Pace, Foreman at USST.  “Our patented equipment and thorough safety measures allowed us to get into these structures and complete the job safely without any incidents.” At USST, safety is our number one priority, and these structures were vast in size and 20-feet off the ground.  By executing a site-specific health and safety plan, our crews implemented confined space entry protocols, air quality monitoring, and other required safety measures to move in and out of these structures expeditiously.  USST’s versatile Combination3® Truck has a powerful vacuum that allowed the crew to reach and dispose of a total of 350 tons of sand and grit material.  To learn more about how USST can restore capacity and flow at your facility call 844-956-1129 or email info@ussubmergent.com.  If you’ve got grit, USST can Grit ‘Er Done!®.

Case Study: 630-Tons of Sand & Grit Removed from Oxidation Ditches

Florida Sand and Grit Grant Program Covers Restoration Costs PROBLEM: Two oxidation ditches at two wastewater treatment plants serving the City of Mount Dora were due for cleaning, having accumulated a significant amount of sand, grit, and debris over 15-years. This loss of capacity was increasing energy costs and reducing efficiency at these treatment plants. U.S. Submergent Technologies’ (USST) knowledgeable crew was called-in with our versatile Combination3® Truck, able to handle multiple setups to complete these projects. SOLUTION: A large oxidation ditch measuring approximately 50-feet wide by 330-feet in length was the first structure our crew tackled. While this oxidation

90-Tons Removed From WWTP

Facility Remained in Full Operation For more than 5 years, the Avon Park WWTP has been accumulating unwanted sand and grit, a problem that often leads to increased energy costs and reduces plant efficiency.  USST’s reliable crew was able to safely and efficiently remove 90-tons of sand and grit from Avon Parks’s headworks and two digesters. With an ADF (average daily flow) of about 850,000 gallons per day and a permitted capacity of 1.5 MGD (millions of gallons per day), this facility sought to restore the capacity of their facility as a preventative maintenance measure.  Using our GritGone Process®, the

Lift Station Maintenance Made Easy

REDUCE THE RISK OF SANITARY SEWER OVERFLOW IN WET WELLS Wet well and lift station maintenance are a frequent source of concern for most wastewater collection systems. Performing regular maintenance can be difficult due to access challenges, costs associated with shutting down pumps, and confined space entry permitting and safety issues.   Wastewater systems rely on lift or pump stations to transport collected wastewater to a treatment plant.  Lift or pump stations typically include two to three pumps for redundancy — all of which require periodic inspection and maintenance.  More often than not, a wastewater facility may only have one operable

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
