Under the River & Around the Corner

70-Cubic Yards of Material Creatively Removed from 660-Feet of Pipe, While in Operation

USST’s Combination3® truck at work under the Hillsborough River

U.S. Submergent Technologies (USST) recently completed work for the City of Tampa on a 300-foot section of interceptor sewer pipe running alongside the Hillsborough River which was experiencing reduced capacity due to a buildup of sand and grit.

Located in a neighborhood, USST setup downstream on the southeast bank of the Hillsborough River.  In order to access the 300-foot 48-inch diameter interceptor sewer pipe, the USST crew had to maneuver through a 360-foot 36-inch diameter siphon and parallel 20-inch diameter siphon under the river, with a 115-degree change in direction.

USST’s unique Combination truck with extended boom, dripless tube system, and jetter were utilized to travel the 360-foot length of siphon, navigate the 115-degree turn, and remove material from 300-feet of interceptor sewer pipe.  USST’s Field Supervisor, Aaron Hood lead the USST crew on the Tampa project, having been with the company since 2014, and has the most experience managing the capabilities of USST’s Combination truck and the GritGone ProcessSM.

“While I was surprised at the amount of material that we encountered in the pipe, I wasn’t surprised that we had the capability to remove it,” said Aaron.

Almost 70-cubic yards of sand and grit was removed from the pipes, restoring more than 26% of its capacity, all while remaining in full operation.

Material removed from the Siphon

“The exceptional ability of our equipment to make a 115-degree turn in submerged conditions and remove a significant amount of material while remaining operational is what separates us from others in the market,” said Denver Stutler, Jr., co-founder and CEO of USST.  “I’m proud of our team and their effort to restore capacity, as well as our working relationship with the City of Tampa.”

Who’s Got the “Quench Factor?”

Best Tasting Water Contest Results,
FRWA Conference

18 utility companies serving customers in Florida came together at the FRWA Conference last week to compete in the Best Tasting Water Contest.  We spoke to Ben Lewis, State Water Trainer, and got the details about FRWA’s annual event.

Contestants are judged on four factors:  taste, odor, color and the quench factor.  The first three categories are easy to understand, but what exactly is “the quench factor?”  When asked Ben about this category, he explained that it is to observe how refreshed you feel after tasting the sample, the “ahhh” factor.

Up to 120 potential points per contestant are up for grabs from three judges.  Each judge can give up to 10 points per category, and the identity of the judges is anonymous.  The three judges are picked in the following way:

  • One judge must be from a regulatory body, such as the FDEP.
  • The second judge must be a vendor present at the conference.
  • The third judge is either the head chef from the hotel or can also be an individual from a water utility that is not participating in the contest.

When judging the water samples, judges assign each sample a number, and it takes the panel about 30-45 minutes to complete the tastings, make their decisions, assign points, and determine a winner.

This year, Talquin Electric Cooperative, Meadows Regional Water took first place in this year’s contest by earning 106 out of 120 points.  They will go on to compete in the 2019 National Rural Water Association’s Water Rally in Washington, D.C.

72-Tons Removed While Plant Remained in Operation

Sand & Grit Occupied Valuable Capacity in Lake Wales

 

USST Crew at work at Lake Wales WWTP’s Oxidation Ditch

Lake Wales Wastewater Treatment Plant (WWTP) was due for maintenance on a large Oxidation Ditch and experiencing reduced plant capacity.  The facility’s treatment process is comprised of a Type 1 Oxidation Ditch operating as a conventional activated sludge treatment facility, and had built up a significant amount of sand and grit material.

U.S. Submergent Technologies’ (USST) Paul Stephenson arrived with a team to the Lake Wales site prepared to remove material from submerged conditions.

“Using our unique Combination truck and GritGone ProcessSM, we were able to efficiently remove about 72-tons of sand and grit while the plant remained in full operation,” said Paul.  “I knew our reliable equipment and exceptional crew would be able to get the job done quickly and on schedule.”

USST’s Combination3® truck at work in Lake Wales

The Combination truck’s extended boom, downhole pump, and jetter was utilized to safely remove sand and grit from the oxidation ditch.  No confined space entry was needed to complete the job, making it safer for the onsite crew and limiting costs for the client.

“When our solution reduces or eliminates the need for confined space entry and gets the job done, everybody wins,” says USST’s CEO, Denver J. Stutler, Jr.  “Less risk taken is always safer.”

Approximately 72-tons of material was successfully removed from the plant and deposited to onsite drying beds, increasing the effective treatment plant capacity to more than 9,000 gallons.

Ted Long, Wastewater Superintendent and Chief Plant Operator for the City of Lake Wales for the past 9-years, has been in the wastewater treatment industry since 1979.  He said, “The process of grit and sand removal went very smooth with no interruptions of service. [USST’s] staff answered all questions and handled the task professionally.  I look forward to working with U.S. Submergent Technologies in the future […].”

96-CY Removed from Two Structures

Crew Gets Creative to Remove Vegetation in Manatee County

 

removing cattails from sludge holding tank

USST recently completed work for Manatee County Utilities, who needed two tank structures cleaned at multiple facilities in order to restore valuable capacity.

The sludge holding tank at the North Water Reclamation Facility in Palmetto, Florida was overrun with cattails and rags.  At initial glance, it looked like a simple job of removing the 4-f00t high vegetation off the top.  However, once the project was underway, an 8-foot root system with rag material woven throughout was discovered underwater.

USST’s unique Combination trucks are equipped with a 49-foot extendable boom, along with vacuum, downhole pump and jetter.

“We used our 49-foot extended boom with hydraulic claw to remove the vegetation from the holding tank while it remained in operation,” says USST’s Field Supervisor, Paul Del Favero, who has been with the company since 2015.  Lead by Paul, the USST crew removed almost 60-CY of material from the structure and the project was completed on schedule.

USST’s Field Supervisor, Paul Del Favero

Meanwhile, a FOG tank at the Southeast Regional WWTP in Bradenton, Florida was also in need of cleaning.  We talked with Manatee’s Utilities Plant Maintenance Supervisor, Donny Adams regarding the FOG tank project, who has been with Manatee County since 2006.

“The 20-foot diameter by 15-foot high tank has a mixer that needed service, but we were unable to access it due to the large amount of grease that had solidified on the bottom,” said Donny.  Approximately 4-feet of FOGs lay on the bottom of the tank, and was removed by the USST crew via confined space entry.

“We used supplied air, life lines, blower fans, gas meters and more, following all protocols for confined space entry, and ended up removing 36-CY of material,” confirmed Paul Del Favero.  Despite the large amount of material needing to be removed from the tank as well as the difficult conditions, the project was completed ahead of schedule, giving back valuable capacity to the facility.

“Storage capacity had been cut in half due to this tank being out of service.  The crew that was onsite did a tremendous job getting the tank cleaned out very quickly,” confirmed Donny, “[…] we really appreciated the fantastic job they did.”

80-Cubic Yards Removed from Wet Well

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 wet well, 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 out of service and the pumping capacity of a second pump was greatly reduced and beginning to clog on a regular basis.  SJCUD was concerned about losing another pump and needed to take action.”

USST Crew member at work in Anastasia Island Wet Well.

With the help of USST’s Combination3® truck and equipment, the USST crew removed 80-CY of material from the wet well via confined space entry.  Due to high levels of H2S (hydrogen sulfide) gas, USST crew members were extremely cautious when entering the wet well during the project.

“We follow all safety and compliance procedures when entering a confined space, taking extra care when high levels of gas are present, including using supplied air with emergency backup tanks, explosion proof vent fans, LED lighting and more,” said USST Field Supervisor, Paul Del Favero.

The USST crew safely and successfully removed sand, grit and rag material from the bottom of the wet well, and the pump station has since gained back full pumping capacity.  By restoring capacity, pump station performance is improved, reducing pump run times and frequency of mechanical wear and tear.

“The project was a great success and we are very pleased with U.S. Submergent’s commitment to get it done given the extremely difficult conditions,” said James Overton, P.E.  “We are grateful that U.S. Submergent was able to act quickly and get it done.”

Confined Space Entry in the Wastewater Industry

A Solution to Limiting Confined Space Entry

 

Confined spaces can be deadly.  Each year, many people are seriously injured or killed while working or attempting to rescue those in confined spaces across a wide range of industries.

The term “permit-required confined space” is defined by OSHA as possessing one or more of the following characteristics:

  • Contains or has the potential to contain a hazardous atmosphere
  • Has walls that converge inward or floors that slope downward and taper into a smaller area that could trap or asphyxiate an entrant
  • Contains other recognized safety or health hazards, such as unguarded machinery, exposed live wires or heat stress

USST crew members at work in aeration basin.

In the wastewater maintenance industry, there are many situations that can require confined space entry, most commonly when structures have limited or no means of ingress or egress such as wet wells, digesters, or aeration basins with high tank walls.  The removal of rag material from wastewater structures is another circumstance where confined space entry is most likely required during maintenance routines.

Dangers of confined spaces within wastewater infrastructure can include:

  • Lack of oxygen
  • Poisonous gases, fumes or vapors
  • Liquids, solids or gases that can suddenly fill the space or release gases into it
  • Lack of buoyancy due to density of liquid
  • Fires and explosions from flammable vapors and excess oxygen
  • Hot conditions leading to a dangerous increase in body temperature

U.S. Submergent Technology’s (USST) Combination3® truck is equipped with a 49-foot extendable crane which allows crew to access material that may be hard to reach over high tank walls or deep wet wells without the need for additional equipment, while reducing the amount of confined space work.

“When our solution reduces the amount of confined space entry required and gets the job done, everybody wins,” says USST’s CEO, Denver J. Stutler, Jr.  “Less risk taken is always safer.”

Because of the capabilities of our patented Combination3® technology, potentially dangerous environments such as headworks, tanks, or manholes do not require confined space entry, reducing liabilities and costs for both ourselves and the customer.

All USST crew members have completed more than 80(+) hours of safety compliance and participate in continuous on-the-job training.

“Every USST crew member goes through extensive confined space entry training.  Proper Personal Protection Equipment (PPE) and safety equipment is always used when confined space entry is necessary,” confirms Paul Del Favero, Field Supervisor at USST.  “Our confined space entry consists of a six-point harness, gas meter, lifeline, Tyvex suits, waders, steel toe boots, gloves, and PPE with a confined space entry permit, door attendant, and entry supervisor.  Safety is life.”

Ops Challenge Takes Over FWRC

2018 “Wastewater Olympics” Regional Results

If you were one of the 3,850 attendees at the Florida Water Resources Conference last week, you may have had the privilege of checking out the some of the Ops Challenge events.  Known as the “Olympics of the Wastewater Industry,” the Ops Challenge follows teams of four as they compete in a series of events, including Process Control, Laboratory, Maintenance, Collections, and Safety in order to secure a spot at the national competition at WEFTEC.

This year, seven teams competed in the overall Ops Challenge, with clever team names such as Destin’s Positive Influents, JEA’s Fecal Matters, St. Petersburg’s Dirty Birds, GRU’s True Grit, St. Cloud’s Methane Madness, and Orange County’s Treatment Outlaws.

Team Positive Influents from Destin Water Users, Inc.

Team Positive Influents from Destin Water Users, Inc. (DWU) was one of the smallest and only private organization competing in the 2018 Ops Challenge, representing a total of 65 employees.  Lead by Logan Law, Destin’s Wastewater Operations Specialist, all members were Class A Operators, and this was their second year competing.  Positive Influents came in first in Process Control and placed second in Collections, having won both events last year in their first year competing.

During the Safety event, teams must respond to a worker that has collapsed inside a manhole while judges time the event and keep score of how the team performs.  Destin’s Positive Influents was able to improve their Safety time by more than two minutes compared to last year’s score.

“At DWU, we try to do things the right way and our Operators carried that attitude into this year’s Ops Challenge,” said Logan.  “It’s a great way for Operators to keep up their training and we have a great bunch of guys in the group.”

Positive Influents ended up placing 3rd overall with a score of 408.02 in this year’s Ops Challenge at FWRC.

“We did leave some points on the table that we should have gotten, but overall I think [we] did an outstanding job,’ said Logan.  “While [we] did not win, we are very proud of the way [we] competed.”

Orange County’s Treatment Outlaws took first, while JEA’s Fecal Matters took second.  Both teams will be moving on to represent Florida in the national competition at WEFTEC later this year.
