Reducing the Risk of Lift Station SSO

Wet wells are a frequent source of concern for most wastewater collection systems.  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 that require periodic inspection and maintenance.  More often than not, the facility may only have one operable pump.  Oftentimes, the water elevation in a wet well cannot be lowered in high-flow conditions such as heavy rain periods or during tourist seasons, with only one operating pump.

Poorly maintained and operated lift stations can increase the risk of a sanitary sewer overflow (SSO).  They can accumulate a lot of sand and grit via I & I, reducing the capacity of the wet well.  The more material there is, the more frequent the pumps must start and stop due to reduced cycle times.  When material accumulates in the wet well and the lift station relies on only one working pump, the risk of SSP is increased.

USST Performing Wet Well Maintenance in Tallahassee, FL

Performing maintenance on wet wells is a problem worth solving in order to reduce pump run time and energy costs and prevent debris and material from accumulating and creating new issues downstream.  Access and confined space entry are also challenges associated with inspecting and maintaining lift stations that add to the complexity of getting the job done.

With these challenges, is there a way to restore wet well capacity easily and safely?  We believe there is.  USST has developed a new solution to restore the capacity of wet wells while they remain in full operation.  We are equipped with all the tools needed on our Combination Truck using our unique GritGone ProcessSM to get the job done safely and efficiently.  Our 49-foot reach allows us to solve most access issues, our jetter allows us to clean the structure, our vacuum removes the material on top (such as fats, oils and greases), and our downhole pump ability allows us to remove sand from the wet well while the lift or pump station remains in full operation.

Our ability to quickly switch between vacuuming and downhole pumping on the spot significantly increases our production rate by having the right tool for the job “on call.”  The typical vacuum truck must wait for a low-flow period; this is not an issue for USST.  Finally, our GritGone ProcessSM generates paint-filter dry sand, ready for disposal.

The USST crew complies with OSHA confined space regulations maintaining proper ventilation, measuring atmospheric conditions and receiving all required health and safety training.  Our team completes more than 40-hours of position-specific training with an experienced field supervisor, including space safety and awareness, fall protection, first aid training and more.

We believe restoring the design capacity of your wet well is a serious job and an important step towards reducing the risk of SSO.  Our goal is to get the job done in the safest and most efficient way possible.  Contact one of our qualified representatives to learn more about our wet well cleaning and inspecting capabilities at (844) 765-7866.

USST removed 21-cubic yards of sand and grit from three structures at Charlotte County’s Burnt Store WRF.  Thanks to our GritGone ProcessSM, the facility remained in full operation while the debris was removed.

John Thompson Jr., Chief Plant Operator at the Burnt Store WRF says, “The project that U.S. Submergent did for us was wonderful.  They not only helped with our grant application, but their crews were very accommodating and […] professional.”

Accessing particularly tall tanks, like Burnt Store’s 30(+)-foot EQ tank, can be challenging.  Luckily, our Combination3® trucks are equipped with a 49-foot knuckle boom crane with telescoping tubes.  This eliminated the need for additional equipment on the jobsite, saving the facility valuable time and money.

Got hard-to-reach places that need cleaning?  Interested in learning more about what USST can do?  Jump on a call with one of our qualified and dependable representatives, Michael or Randy, and they can help you figure out where the problem is and how USST can get your facility back to full capacity.

Safety in Movement

We are moving fast, every day, in both our personal and professional lives.  It is during these busy times when we must focus and be extra attentive of things in motion around us, including ourselves, especially when safety is the goal.

Safety matters most when we are moving; there is a higher probability of things happening that shouldn’t.  People, places, equipment, vehicles and more are constantly on the move, meaning more risk for the individual. “Falls” is the number one cited job site fatality in 2015 according to OSHA1, followed by “Struck By Object.”

Take a glance at OSHA’s “Top 10 OSHA Citations of 2016” if you’d like to learn more about common job site violations, or to simply serve as a reminder for the future.

A culture of safety requires paying attention throughout the day, particularly when there is more to pay attention to.  Consider the different levels of effort required to pay attention while driving in good weather compared to moving fast in heavy traffic in the rain.  As our CEO, Denver J. Stutler, likes to say, “What matters most, is getting it done when it matters!”

Focused individuals lead to a focused organization, which in turn leads to a more productive and enhanced overall operations, all while maintaining safety standards.  Stay safe out there!

Storm Season Is In Full Swing – Are You Prepared?

The Impact of Hurricane Floods on Wastewater Treatment Plants

With two heavy-hitting hurricanes recently battering both Texas and Florida, wastewater treatment plants across the country can learn from what’s happening in these areas to prepare for the potential impact of flooding, storm surges, and other extreme weather on their own systems.

 alt=

Florida Army National Guard soldiers went door to door in Jacksonville, Florida performing search and rescue missions on September 11, 2017 after Hurricane Irma.

In addition to causing billions of dollars of damage from wind and rain, storm surges and flooding from hurricanes Harvey and Irma have wreaked havoc in cities and wastewater treatment plants along the coastlines.  In Palm Beach, Florida, crews were out maintaining and repairing lift stations before, during and after the storm in an effort to keep the town up and running.1  In St. Petersburg and Orlando, Florida, 50o,000 gallons of untreated water flowed into streets and homes after Hurricane Irma.2  Pipelines in Florida are typically designed to handle twice the amount of water they are constructed for, but no system can handle the amounts of rain or storm surges from these types of weather events.

Meanwhile in Texas, the U.S. Environmental Protection Agency estimates that 40 out of 1,219 wastewater treatment plants in the Houston area are out of service due to Hurricane Harvey as of Monday, September 11.  Contaminated flood waters in streets and homes continue to impact the area with high levels of E. Coli and other bacteria and toxins, creating unsafe environments and health risks as residents return to their homes.3

Flooding in Houston, August 31, 2017.

Flooding in Houston, August 31, 2017.

Wastewater treatment plants must be able to operate under any circumstance, so what can you do when storms are headed to your city?  Fortunately, both the Florida Department of Environmental Protection (FDEP) and the U.S. Environmental Protection Agency (EPA) have published flood and storm preparation guides that may help assess your cities current and future situation.

An Emergency Response Plan is the first step in preparing for a major weather event, as well as understanding potential threats and identifying vulnerable areas within the facility.  The EPA’s Flood Resilience Guide is a great resource for preparing wastewater treatment plants for rising waters and takes you through a set of exercises to thoroughly evaluate your facility in order to put a plan in place.  The Storm Preparation Guide provided by the FDEP is a great document to help understand the threat of storms and other extreme weather events and includes a handy checklist on planning, communications, training, staff coordination, staging and more.

Imminent weather can be daunting, but having a solid plan in place and knowing your facility has the pieces in place to handle such a situation can offer peace of mind and keep your city up and running during an emergency situation.

Utility Maintenance: How Debris Gets Into a Facility

Ever wonder how debris gets into your facility?

The United States has between 700,000 and 800,000 miles of underground pipe that ranges from six inches to 240 inches in diameter. This aging infrastructure allows for debris to move through a waste collection system due to cracks and joints in the pipe.

Debris can be naturally occurring or litter. Natural occurring debris includes sand and grit; litter includes fats, oils and greases. Litter debris has been discarded into the wastewater by users of the system —commercial or residential.

Utility Maintenance How debris gets into a facilityDebris accumulates in structures throughout wastewater collection and treatment systems such as pipes, manholes, lift stations, wet wells, grit chambers, aeration basins, tanks, digesters and other requisite structures.

Sand and grit travel through the wastewater collection and treatment systems, ultimately ending up at the wastewater treatment plant. The material increases with aging infrastructure and can be exasperated by significant rainfall.

The accumulation of sand and grit in the aeration basin decreases capacity. This means the amount of oxygen is reduced and there is an increased use of energy and labor.

Utility Maintenance Matters

Debris issues are usually negotiated around until the adverse effects become critical. The longer the debris remains in the structure, the more challenging removal can be.

The overall risks to be considered include catastrophic, equipment and regulatory risks.

What Debris Does to Your Facility

The Problem With Debris

Debris gets into your facility through joints, seams, gaps and cracks that happen as the infrastructure (such as gravity systems and pipes) ages and shifts over time.

Let’s focus on the problematic effects debris can have on your infrastructure.

It can:

• Wreak havoc on the treatment process.
• Increase costs and reduce overall efficiencies throughout the system.
• Cause abnormal wear and tear on system components, including pumps and other mechanical components.

What Debris Does to Your Facility

Generally speaking, debris can greatly impact efficiencies of mechanical and biological systems.

Mechanically speaking, it can affect operational aspects of the collection and treatment system, including full or partial plugging of outlets and pump suctions.

When accumulated sand and grit cover air bubble diffusers on the bottom of aeration basins, the consequence is a harsh increase in energy required to deliver the air to the wastewater for aeration. This increases energy costs.

The longer debris remains in the structure, the more challenging it can be. Luckily, USST has the equipment and experience to resolve accumulated debris issues in wet infrastructure.
