Florida Sand and Grit Grant Program Aides in Restoration Costs PROBLEM: An oxidation ditch at the Lake Wales Wastewater Treatment Plant had accumulated over the course of a few years a large amount of sand and grit material. This accrued material was causing a loss of capacity, a decrease in flow, and the plant was not functioning efficiently. The facility’s treatment process is comprised of a Type 1 Oxidation Ditch operating as a conventional activated sludge treatment facility measuring 320-feet by 70-feet. U.S. Submergent Technologies’ (USST) knowledgeable and experienced crew was called in to clean this large structure while it

A Hazardous Challenge Met by USST Crews and Equipment In an urban area of Central Florida, two wet wells had filled up rapidly with rag, FOG, and sand and grit material. These structures serve as master lift stations for a city, (commercial and residential areas) keeping wastewater moving 52 feet below grade to the wastewater treatment facility. U.S. Submergent Technologies’ (USST) equipment was able to remove this stubborn material from the depth required and our crews came in to meet this challenge head-on, safely, and efficiently. “This is the deepest wet well we have cleaned and might be the deepest

Challenging Confined Space Entry in Anastasia Island Anastasia Island’s Wastewater Treatment Facility (WWTF) was experiencing reduced pumping capacity due to accumulated solids in their influent lift station, a facility with a permitted capacity of 4.95MGD.  Due to the challenging nature of the 35-foot deep structure, Anastasia Island’s wet well hadn’t been cleaned in several years, resulting in the accumulation of a significant amount of material. “The pump station consists of four Gorman-Rupp self-priming solids handling centrifugal pumps,” explained James Overton, P.E., at the St. Johns County Utility Department (SJCUD).  “Due to grit and rags that accumulated, one pump was completely

180-CY Removed in Davie, Florida   Capacity was recently restored to the Town of Davie’s WWTP as part of their Capital Improvement Program, a facility which handles an average daily flow of around 3MGD.  More than 180-CY of sand and material was removed from Davie’s 20-foot high surge tank while it remained in full operation.  Using USST’s extended boom and Combination3® technology, the material removed was immediately ready for disposal. John McGeary has resided as Chief Operator of the Town of Davie’s WWTP for almost five years, and has 38 years’ experience in the wastewater industry.  He says “[I was]

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

Hard at Work in Daytona Beach   That’s the weight of nearly 1,000 Ford F-150s! USST is working hard to restore the capacity of the City of Daytona’s Bethune Point 13 MGD water reclamation facility.  Over 2,000 tons of material – primarily sand and grit – are estimated to be removed from the facility upon completion of this project.  After being offline for approximately two years, this facility is progressing towards being fully operational once we complete our work. Sand and grit aren’t the only materials USST can remove from a facility.  We also have the ability to remove rags, vegetation
