Four structures at the City of Quincy’s Wastewater Treatment Plant were overdue for cleaning, due to a significant amount of sand and grit accumulation over the last 30-years.  With multiple setups needed to complete the project, the USST crew mobilized to the site armed with the versatile Combination Truck and removed the built-up sand and grit.

A 55-foot diameter digester and a 75-foot diameter nitro tank were the first two structures the crew tackled.  While the structures were in full operation, USST utilized the Combination Truck’s downhole pump combined with the GritGone Process® and removed sand and grit material.  The truck’s 49-foot extendable boom was utilized to reach over the 15-foot and 12-foot high walls of each structure, respectively.  Because the tanks did not have to be taken offline or drained down in either case, confined space entry was not required.

Next, the USST crew turned to the third and fourth structures needing to be cleaned: two combined fermentation and anoxic tanks, both measuring approximately 24-feet wide by 80-feet in length.  These tanks needed to be taken offline due to capacity issues, and a drain down was necessary to effectively reach the material.  The work was performed via confined space entry by the USST crew utilizing the Combination Truck’s powerful vacuum technology.  Check out the project recently completed in Delray Beach to learn more about our vacuum capabilities. 

“Having the ability to clean both wet or dry conditions on a jobsite gives us an advantage in the field,” said USST Operations Manager, Paul Del Favero.  “We don’t have to bring multiple pieces of equipment to the site and we can accommodate clients who are unable to take structures offline.”

In total, approximately 340-tons of sand and grit were removed from Quincy’s four structures and disposed of onsite.  The project was completed ahead of schedule, restoring valuable capacity to the treatment plant.

“U.S. Submergent did a very professional job with little or no issues with the operation of the plant,” said Mo Cox, Assistant Director of Utilities for Quincy.

An aeration basin at the Delray Beach South Central Regional Reclamation Facility was overdue for cleaning, having built up a significant amount of sand, grit, and rag material that needed to be removed.  The USST crew mobilized to the site armed with the versatile Combination Truck, well-prepared to handle the project.

Made up of three 60-foot by 60-foot bays, the aeration basin was drained down when the crew arrived.  To aid the cleaning and rehabilitation of the tank, diffusers were removed from the bottom of the bays and USST crew utilized a skid steer to assist in the removal of the high-density material from the structure.

The Combination Truck’s powerful vacuum was used to remove sand, grit, rags, and sludge, and has the ability to get over high walls without losing power.  USST’s vacuum is powered by a blower capable of delivering nearly double the CFM of a standard vacuum truck, allowing the crew to remove large amounts of wastewater residuals and complete the job quickly. 

“Our years of experience provides us with the ability to adapt to unknown conditions and be prepared for obstacles we may face on the jobsite,” said Paul Del Favero, one of USST’s Operations Managers. 

In total, approximately 724-tons of rags and debris were removed from Delray’s structure and disposed of offsite, restoring valuable capacity to the treatment plant.

How U.S. Submergent Technologies Helps You Minimize the Need for Confined Space Entry

The need for confined space entry, and particularly permit-required confined space entry, can considerably increase the cost of maintenance for wastewater collection and treatment systems, including pipes, tanks, lift stations, and stormwater drains. 

Access is one of the largest cost drivers in the removal of debris

U.S. Submergent Technologies’ GritGone Process® for sand and grit removal can be performed without any interruption to your normal plant operation. Most of the time, this means that our standalone cleaning systems can get to challenging, hard-to-clean environments without requiring confined space entry. 

Using our Combination Trucks and expertly trained crew, we specialize in accessing hard-to-reach infrastructure and can clean a wide variety of tanks and large-diameter pipe in both submerged and surcharged conditions. We’ve cleaned through a right angle and a syphon while it remained in operation, 1,000 feet of sanitary interceptor, accessed a manhole in a river, vacuumed over 25-feet high walls, and removed materials from 30-feet deep wells. Read our recent case study, covering how we removed 22-cubic yards of sand from a splitter box at a Central Florida wastewater treatment facility while it was in service and without the need for risky confined space entry.  

Confined space entry: when you need a permit and when you don’t

OSHA defines a confined space as one that has limited openings for entry or exit, is large enough for entering and working, and is not designed for continuous worker occupancy. 

Permit-required confined spaces are a subset of confined spaces that:

  • May contain a hazardous or potentially hazardous atmosphere.
  • May contain a material which can engulf an entrant.
  • May contain walls that converge inward or floors that slope downward and taper into a smaller area which could trap or asphyxiate an entrant.
  • May contain other serious physical hazards such as unguarded machines or exposed live wires.
  • Must be identified by the employer who must inform exposed employees of the existence and location of such spaces and their hazards.

Taking measures to pull confined space permits and developing a written permit space program is time consuming and can extend the period of maintenance past what is feasible for a given lift station, pipe, or tank.

Alternative to a full permit entry is still costly and risky

Even under conditions that allow an alternative to full permit entry, there are still time-consuming and expensive hurdles to overcome. For example, if you can use monitoring and inspection data to demonstrate that a potentially hazardous atmosphere can be made safe for entry using continuous forced air ventilation, you need to test the internal atmosphere of the space for oxygen content, flammable gases and vapors, and the potential for toxic air contaminants before any employee enters it. You must also provide continuous ventilation and verify that the required measurements are performed before entry.

When confined space entry isn’t avoidable

In certain cases, confined space entry can’t be avoided. There could be a significant buildup of rag material or other debris that can’t be captured by other means, or maintenance needs that require hands-on expertise.

In cases like these, you can trust that every member of U.S. Submergent Technologies’ experienced field crew has completed more than 80 hours of safety and compliance training, with ongoing on-the-job instruction.

21-Tons Removed from Lift Station In Operation

FOGs, sand, grit, and rag material had accumulated over time in a Central Florida lift station, reducing its overall capacity.  A buildup of material in a wet well such as this has the potential to cause several issues, including increased pump run times and wear and tear on equipment.  USST was able to perform sand and grit removal from this 20-foot deep lift station in operation very quickly. 

Typically, multiple pieces of equipment would be needed to tackle this challenging issue.  Fortunately, USST’s Combination truck is more than just a vac truck.  Sporting a vacuum, downhole pump, jetter and extendable boom on one chassis, the Combination trucks have the ability to clean in wet or dry conditions in up to eight different setups.

“Lift stations are one of our specialties,” said Aaron Hood, one of USST’s knowledgeable Field Supervisors.  “Our equipment is designed to clean in a variety of ways, quickly and safely.  We can remove material at an increased rate without having to put the crew down in the tanks.”

The Combination3® Truck
The Combination Truck

In this case, the USST crew first removed FOGs and floating rags from the surface of the wet well using the Combination Truck’s powerful vacuum.  The downhole pump was then engaged to remove approximately a foot and a half of sand, grit, and rag material from the bottom of the structure.  All of this occurred while the lift station was in full operation.  Risky confined space entry was not needed, as is typical on a project of this kind, due to the efficiencies of our equipment.

In total, approximately 21-tons were removed from the structure with no issues.  Due to the GritGone Process®, the sand and grit material was paint-filter dry and ready for offsite disposal.

Access issues had prevented a covered splitter box at a Central Florida wastewater treatment facility from being cleaned.  A large amount of accumulated sand and grit had built up over time, and the structure was experiencing reduced capacity. So how was this splitter box cleaned while in service?

A splitter box serves to separate influent flow to various structures such as aeration basins or oxidation ditches and can be hard to shut down or bypass flow in order to perform regular maintenance. 

“Cleaning a structure while in operation is our specialty,” said Aaron Hood, experienced Field Supervisor at USST.  “This particular splitter box was also covered, adding a layer of complexity to the project, but didn’t prevent us from being able to remove the large quantity of material in a short amount of time.”

The 55-foot long by 7-foot wide structure had two access points on top of the tank.  USST crew, along with the powerful Combination Truck, was able to employ the jetter to jet material back to the downhole pump positioned at the manhole for removal.  The work was performed in submerged conditions, while remaining in operation, a challenge the facility had previously been unable to solve.  Since the splitter box was cleaned while in service, confined space entry was not required to complete the project.

USST utilized the unique GritGone Process® to remove 74-tons of sand and grit in total, generating paint-filter material ready for disposal.  Check out our video to get a more detailed explanation of how our GritGone Process® works.  The project was completed on time and the client saved valuable time and resources by not having to shut down operations or figure out a bypass solution.

Florida Braces for Flooding as Downpours Continue


Rainfall predictions across the state of Florida.
Rainfall forecast courtesy of The Weather Channel.

Heavy downpours continued over the weekend, making this summer one of the wettest some parts of Florida have seen in a long time.  Last week, drivers needed rescuing from their cars stranded in rising waters in Orange County when more than 4-inches of rain fell.  In Miami-Dade, nearly 6-inches fell in one hour, causing flash flooding while flood warnings were issued across most of West, Central and South Florida. What’s different about this type of flash flooding and rainfall and the impact it has on wastewater treatment infrastructure?

Most Floridians are familiar with daily summer thunderstorms, but these storms have been lingering longer and dumping heavy rains multiple days in a row.  When the ground becomes this saturated with water, it has nowhere to go. 

“What is most unusual about this pattern is that rain will be an all-day on-and-off rain rather than the once or twice a day severe thunderstorms,” meteorologist Jonathan Belles said.  Showers and storms will be possible in the middle of the night too, which is not typical of summer.”

So how does rainfall impact wastewater infrastructure? During periods of severe rainfall such as this, the rate of flow in a stormwater system increases and can exceed the treatment facility’s capacity, as well as potentially cause overflows.  The influx of water into a system also brings sand.  Sand, unlike other debris such as rag material, FOGs, and grit, is an unintended consequence of increased inflow into collection systems.

What can utilities do to prevent or address these issues when they occur?

One obvious solution is to rebuild or repair infrastructure.  But these projects can be costly to cities and taxpayers.  Employing barriers around key assets or diverting flow may also be a short-term solution. 

Another more cost-effective solution is to perform regular maintenance to ensure collection and treatment systems can operate at full capacity when needed.  When wet season flows increase significantly compared to dry season flows, sand can be transported into the collection and treatment systems and may be accumulating without anyone noticing.  Since the water in tanks at facilities are not see-through, accumulated sand at the bottom of these tanks remain unseen and unnoticed.  Eventually, the increase of sand into wastewater treatment infrastructure can reduce treatment volume and increase energy use.  Over time, this buildup can potentially cause overflows and other issues if the system is not able to operate at full capacity.

This is where regular maintenance can work to a facility’s advantage.  If the cost of annual maintenance is less than the amount it would take to rebuild or repair infrastructure, then removing sand at the treatment system may be the best option.

Is there an end in site for all this rain?

Rainy season in Florida typically lasts from Mid-May through Mid-October, with the heaviest rainfall occurring in June, July, and August.  We can expect the soggy weather to subside sometime late October, traditionally the beginning of Florida’s dry months. 

As for this week, forecasts show that parts of Florida may finally get the opportunity to dry out.  Scattered showers are shown across the state but are predicted to be more in line with a traditional Florida summer.  The wet weather West, Central and South Florida were experiencing last week is now headed to the panhandle where flood warnings have been issued.
