3 Oxidation Ditches, 2 Wet Wells… and a Partridge in a Pear Tree

Multiple Structures in Full Operation While 194-CY Removed

Five structures at a Northeast Florida Wastewater Treatment Facility (WWTF) were experiencing reduced capacity due to a buildup of sand and grit.  The WWTF, which manages an average daily flow of nearly 5 MGD, had three oxidation ditches and two wet wells in need of maintenance.

Measuring 50-feet wide by 230-feet in length, the three oxidation ditches accumulated a significant amount of sand and grit material.  Aaron Hood, Field Supervisor at U.S. Submergent Technologies® (USST) mobilized the USST crew to the facility and was able to successfully clean all three structures while in full operation and without having to resort to confined space entry.

“Cleaning in submerged conditions is USST’s specialty,” said Aaron.  “Our Combination truck outfitted with extended boom, downhole pump, and jetter allows us to be extremely efficient in removing material without having to drain down the tank or require confined space entry.”

Not having to drain down a tank can save a client valuable time and resources in order to remove material.  USST’s equipment performs best in submerged and surcharged conditions, and tank height is almost never an issue for the Combination truck.

Two wet wells were also in need of sand and grit removal, and the USST crew accessed the material without issue and while in full operation.  USST’s unique, GritGone Process® generated approximately 194-cubic yards of sand and grit material removed from the five structures and the paint-filter dry material was deposited onsite.
