OPW’s Watertight Wonder, the ElectroTite Tank Sump
Tank sumps are critical components in the fueling systems at retail and commercial fueling sites in their role as isolation chambers that provide secondary containment for tank fittings, valves and submersible pumps, along with easy access to the storage tank itself for service and maintenance. Since the creation of underground fuel-storage systems, however, fuel-site operators have waged a constant battle against water intrusion into their tank sumps.
This is a major concern as water that enters a tank sump can trip alarms, cause microbial growth, induce rusting of metal parts and, in the worst-case scenario, invade the fuel that is contained in the underground storage tank (UST), which will compromise its quality. Preventing water intrusion is so difficult because there are a number of ways it can enter the tank sump and fuel-storage system: through leaking tank-sump lids; cracks in sump walls; damaged entry fittings; and, most commonly, through conduit runs.
When water intrusion does occur and an alarm is tripped, the sound that accompanies it may as well be the ringing of a cash register, since the site operator will soon be reaching for his or her checkbook in order to pay not only for the service call, but for a pump out of the tank sump. The cost for the following hypothetical pump out example is based on conversations with the service manager of a United States UST service and installation company based on the East Coast:
Sump Pump Out Cost Calculator
Travel Miles ($0.85/mi)
Vacuum Trailer Rental Fee
Gal/Petroleum-Containing Waste (PCW); $1.80/gal
The costs, miles and hours for a pump out will obviously vary from site to site, but the price for this average example – multiplied by the 15-20 pump outs per UST, on average, that can occur annually at a fueling site – will result in an exorbitantly high cost to remediate water-intrusion events, with many fuel-site operators unable to reconcile this expense.
To The Rescue
The year 2017 will be looked back on as a landmark one for fuel-site operators in their constant battle against tank-sump water intrusion. It was then that OPW Retail Fueling, Smithfield, NC, introduced the revolutionary ElectroTite No-Drill Tank Sump to the market. What made ElecroTite a true game-changer was its status as the industry’s first and only tank sump that featured factory-installed conduit ports with an integrated electrical wiring junction box. This allows the sump to be installed as-is at the fueling site, with no intrusive drilling required. This feature eliminates the risk that unintended leak points will result due to the drilling of entry points, while also optimizing installation time.
Other beneficial features of the ElectroTite tank sumps include:
Sealed conduits are located above the water table
Elimination of all conduit entry fittings
Reduced entry points lower number of potential leak points
Conduit lines can be installed, inspected and repaired through the top of the sump
Can access wiring box for inspection without entering confined sump area
Explosion-proof junction box allows space to reroute or daisy-chain communication wires to spill containers and tank monitors, eliminating additional conduit runs to the tank field
Electrical shield allows positioning of high- and low-voltage sensor wires in same box
Conduit can be potted entering box, exiting box, or both
Will replace up to six:
Conduit entry fittings
Explosion-proof junction boxes
The bottom line is that the design and operation of ElectroTite tank sumps make it the most watertight system available, resulting in a fueling system that optimizes efficiency, reliability, cost-effectiveness, environmental protection and the safety of both the site and the customers who patronize it.
Seeing Is Believing
Of course, it’s easy to say that something is the best thing since sliced bread, but proving it is a different matter entirely. Well, after nearly four years of observation of in-the-field installations, the ElectroTite has more than lived up to its advance billing. The chart below compares tank-alarm remediation costs for two United States sites that have had ElectroTite tank sumps in operation for nearly four years to an average non-ElectroTite site:

Let’s take a closer look at the individual installations and the conditions the sumps have encountered:
Site 1: Three ElectroTite tank sumps were installed at this Midwestern U.S. site in November 2017, one each for unleaded gasoline, premium gasoline and diesel USTs. As you can see, this is turning out to be the poster child for the effectiveness of the ElectroTite tank sumps. In that time, not one single tank-sump alarm event has been recorded, resulting in zero cost for the overall maintenance of the sumps.
Site 2: Two ElectroTite tank sumps were installed at this Southeastern U.S. location that is situated near an extremely high water table in September 2018, one each on the unleaded and premium gasoline USTs. Since then, two alarm events have been recorded at the site (both on the unleaded sump in July 2018 and September 2020), but only one required a pump out.
Fuel-site operators have always had to keep water from intruding into their below-ground fuel-storage systems, but that has proven to be easier said than done. Until 2017, that is. With the introduction of no-drill tank-sump/conduit-less technology to the market, epitomized by OPW’s ElectroTite system, the battle against water intrusion is being won more often by site operators. The result is a fueling operation that can more reliably deliver uncompromised fuel to its customers while helping to make expensive, time-consuming and frustrating sump pump outs a welcome thing of the past.

TARGETING THE ISSUE AND PREVENTING IT AT THE SOURCE
Water ingress and corrosion of fueling equipment is a systemic problem that is becoming increasingly more complex with Ultra-Low Sulfur Diesel (ULSD), the adoption of biofuels, and new engine technology that demands strict fuel quality. Most site owners are aware of this problem and are looking to take corrective and preventive steps against corrosion. When issues necessitate more-than-regular maintenance, it is time for action.
Cumberland Farms was actively seeking a solution to their corrosion challenges and were interested in trying out HydrX. Drawn to the product feature-set and comprehensive support of Veeder-Root, HydrX seemed like a no-brainer. The simplicity and support proved essential, as the HydrX test results spoke for themselves; especially during the unprecedented environment of the COVID-19 pandemic.
“The HydrX Fuel Conditioning System’s ability to remove standing water from the lowest point of a fuel tank coupled with our unique fuel filtering technology helps site owners avoid costly equipment failures and downtime caused by excessive corrosion.”
– Stephen Coppola, Global Product Manager, Veeder-Root
A FAMILIAR PROBLEM – WATER
The systemic issues Cumberland Farms experienced at their initial HydrX installation site are not unique to the industry. When fuel, microbes, and water combine, the result is a corrosive environment.
Advancements in diesel fuel, particularly Ultra-Low Sulfur Diesel and Biodiesel, create an environment where microbial growth can flourish. Water entry into the diesel storage environment is inherent in the process as it enters through leaky seals, flooded spill buckets, atmospheric moisture, and deliveries. Water entrained in a warmer fuel load may fall out of suspension when it enters the tank and cools down. It is the fuel-water interface that is central to microbial growth because the water provides a suitable environment for microbes to thrive within the underground storage tank.
For Cumberland Farms, that meant frequently troubleshooting emergency line leak test failures by replacing check valves, replacing dispenser filters due to slow flow, and even performing full STP replacement within 1.5 – 2 years from the date of installation.
ASSESSING THE SITUATION
Jim Scholes, Senior Project Manager of Construction, and his team at Cumberland Farms, knew that HydrX could help optimize the health of their diesel tanks by reducing water contamination and the Microbiologically Influenced Corrosion (MIC) that comes with it.
To fix these problems at the source, the Veeder-Root team began with a preliminary site inspection and evaluation. This included obtaining baseline fuel samples from the tank and nozzle, analyzing samples for baseline acidity and moisture content, and taking site measurements for the HydrX Fuel Conditioning System.
Site measurements were critical to understand how the tank was tilting. The Water Intake Device (WID) of HydrX is designed to extract water from the lowest point in the tank and is customized to work with the unique conditions at any site.
The fuel samples from the tank showed the expected symptoms for any site being affected by long-term water issues. There was visible corrosion on components exposed to the storage environment, and evidence of water and microbial growth in fuel samples obtained from the tank bottom.
PUTTING THE PLAN INTO ACTION
Solving the water issues discovered during the site evaluation began with a tank cleaning prior to the installation of HydrX, in order to reset the tank to a healthy baseline and to ensure optimum performance of the system. A tank that is clean to start results in a lower cost of ownership due to less frequent filter replacements, component services, and/or fueling system maintenance.
Next, the HydrX Fuel Conditioning System was installed to provide continuous water removal within the diesel underground storage tank. This particular tank was tilted away from the STP sump, which put the stagnant water 22 feet away from the point of entry into the tank. The WID was sized to reach this lowest point of the tank, ensuring the stagnant water would be eliminated.
I definitely want to use HydrX going forward, I think it has value in the new construction environment. Even with a new site, new tanks…we’re still seeing issues with ULSD. In my opinion, we should be installing this in new construction rather than just use it in a retrofit application at the trouble sites.
– Jim Scholes, Senior Project Manager of Construction, Cumberland Farms, EG Group
HYDRX WATER REMOVAL
Since the installation of the HydrX Fuel Conditioning System, the results have spoken for themselves. Within the first 24 hours, HydrX removed just over a half-gallon of water that had entered the tank since the tank was cleaned. Over the next 30 days, the extracted water volume continued to increase incrementally to nearly 1 gallon. The quality of the tank bottom fuel samples was visually evident. The samples were clean and bright with no signs of water present in the fuel.
After just 90 days, extracted water volume nearly doubled, fuel quality within the tank was restored, and fuel samples from the bottom of the tank were indistinguishable from those at the nozzle, indicating that the conditions in the tank have stabilized and microbial growth is being mitigated.
SEEING THE RESULTS
Looking at key leading indicators to corrosion, water content (PPM) in the samples from the bottom of the tank have shown a downward (favorable) trend. After 120 days, the values have stabilized at a low level and are now equivalent to the samples from the nozzle. The pH of the samples from the bottom of the tank started in a corrosive range. Since the HydrX installation, pH has also continued to improve, approaching 6.5 which is on the very edge of a passive oxide surface with no ongoing corrosion.
WATER CONTENT & pH
Use of the HydrX Fuel Conditioning System lowers the water content within the diesel fuel and restores pH to non-corrosive levels.
PUTTING A PAUSE ON CONDITIONING
To further prove system efficacy, HydrX was turned off for a period of time. It did not take long for there to be visible signs that the quality of the fuel was degrading and the eventual corrosive conditions would return.
After 30 days, there was evidence of standing water and dark particulate in the fuel. The fuel itself was losing clarity and turning to a dark amber color. When HydrX was restarted, there were immediate signs that the system was correcting the conditions inside the tank – standing water was eliminated and the clarity of the fuel returned.
THE PROOF IS IN THE PETROL
From the samples pulled at 120 days after installation, the evidence is clear that the system is working. Prior to the installation of HydrX, emergency service calls to correct corrosion related issues were frequent and started to show up not long after tank cleaning.
These issues consumed resources and caused downtime at the site. Post installation, corrosion-related service calls were eliminated and there are no leading indicators that they will be returning anytime soon. HydrX is protecting the conditions inside the tank from water and microbial growth.
DIESEL TANK MAINTENANCE
It is working so well, in fact, that after just a few months with HydrX in place, Cumberland Farms is planning a roll-out of the system at their new construction properties to prevent issues before they happen, not only as a reactive measure at existing sites.
“The return on investment? It pays for itself.”
– Chris Desaulniers, FSS Project Manager, Cumberland Farms, EG Group
TALK TO AN EXPERT
Other systems work to remove water from only the immediate area around the submersible turbine pump — HydrX is different.
HydrX uses suction tubes that extend along the Water Intake Device, removing water all along the tank bottom. Its unique vacuum mechanism is powered by the STP, continuously circulating tank bottom fluids through a filter and water containment vessel in the sump.

Operators of gas stations have a lot on their minds, and the water within their fueling system may seem like a low priority, but there are many reasons to consider water as a serious threat that needs to be removed.
The primary issue is that water, fuel and bacteria, are the three common components that combine to create a corrosive environment around fueling systems. In sump spaces water is often combined with ethanol vapors as the catalyst for microbial growth, but in-tank corrosion is more likely to happen with ultra-low sulfur diesels or biodiesels.
Hidden Below the Surface
Of the three common components, water is the easiest to address but first you need know where it’s hiding.
Many underground storage tanks have magnetostrictive probes with separate water detection floats (1), but they require a minimum water level of ¾” in the probe area to go into alarm. This is great for identifying a catastrophic breech of the tanks integrity but less effective for identifying water that as slowly accumulated below that threshold over time.
Depending on the tilt of your tank there could be stagnate water at the lowest point of your tank (2) that could be a breeding ground for bacteria.
Identifying Water is Key
When microbial growth feeds on components of the fuel, biomass then settles in the water at the bottom of the tank and creates the acidic environment that leads to corrosion. The key to avoiding tank corrosion is identifying the water in the tank and removing it. Once water is removed, one of the common components of the equation is gone and the environment is no longer corrosive.
April 16, 2019, EDITOR’S UPDATE: The graphic incorrectly states there are 10,700 gas station in the United States when there are about 168,000 and of them, about 126,658 are convenience stores that sell gas. We apologize for this gross error and thank Pedro De Jesus for bringing it to our attention.
If you are looking for the smooth flow of operations at your gas station then make sure the forecourt of the station receives the appropriate amount of maintenance.
