Hybrid Containment Solutions

There are many methods for secondary containment, but only Justrite offers adaptable custom oil filtration solutions to complement and improve any containment system.

Complementary Oil Filtration Systems

Aside from providing the most dependable secondary containment on the market, our oil filtration and containment systems are also known for their versatility. The technology that makes up our core solution components deliver the flexibility to complement and improve other secondary containment methods. Depending on the variables present, we’ll marry our oil filtration technology alongside whatever products are necessary to solve our customers’ needs.

Fiberglass containment walls, such as Strongwell® COMPOSOLITE® Walls, are often used by utilities that favor the look of above-ground containment but want to avoid the time and labor necessary for installing concrete. The addition of a Geomembrane Liner and HFF Oil Stop Valve vastly improves this aesthetically-pleasing containment method.

If space constraints could prevent SPCC compliance, we offer two different options for oil filtration and containment. Use our geomembrane liner with corrugated ADS (or HDPE) pipes to create a smaller footprint. This method is easily integrated with multiple components of our core solutions, like our Barrier Boom oil filtration panels.

We also recognize the oil containment challenges present in many underground transformer vaults, especially in urban settings. Our line of VIPOR (Vault Integrated Pump and Oil Redundancy) systems provide automatic dewatering and oil filtration while evacuating water from secondary containment vaults and sumps.


When Space is Limited, Use Perforated Pipes for a Smaller Footprint

For sites requiring a smaller footprint or where space constraints are present, we recommend using a geomembrane liner along with perforated ADS (or any type of corrugated HDPE) pipes to create additional void space within the containment area (and increase the void volume ratio).

The oil capacity volume increases exponentially through the storage capacity of the pipes, thus requiring fewer construction materials (liner, pipes, etc.) and creating a smaller footprint. Site-specific variables help determine what drainage solution to use. In most cases, especially when the water table is close to the surface, water evacuates through a solid line from the containment area into a sump containing a VIPOR-SOWF, an automatic sump pump and oil filtration system that prevents oil from discharging into the environment. When installed below-grade on sloped sites with impervious soils, use Barrier Boom oil filtration panels for passive, compliant drainage.

Strongwell® COMPOSOLITE® Walls – An Affordable Alternative to Concrete

Fiberglass composite walls, such as Strongwell COMPOSOLITE Walls, are an adequate secondary containment solution when aesthetics is important to the end-user. But, an effective system must contain walls, a floor and a method to evacuate waste water to prevent water from pooling within the containment area. We offer several complementary oil filtration solutions to achieve complete containment and ensure SPCC compliance when using fiberglass walls around substations. If the subsoil is impervious, the walls can be installed directly into the ground; for sandy or undetermined subsoils, use a geomembrane liner.

To prevent a "swimming pool" from forming inside the walls after every rain fall, water must be evacuated. One option is to cut windows into the below-grade sections of the walls that house Barrier Boom windows for oil filtration. These allow rainwater to flow off the site, while preventing the flow of any hydrocarbons.

But, if using a geomembrane liner, the better option is to install a drain in the floor. Plumb the drain to a vault outside of the containment area housing an HFF Oil Stop Valve or a VIPOR-SOWF. The HFF processes all storm water and shuts off in the event of a significant hydrocarbon release; the VIPOR provides passive oil filtration and containment by automatically discharging oil-free water off-site.

Frequently Asked Questions

Many of our substations already have secondary containment, most commonly concrete moats or composite walls. We often need to manually dewater these after a heavy rain. Do you offer any automated pumping or filtration solutions that can help us cut down on O&M time?

When it comes to retrofitting existing containment, it’s important to identify the main source of concern and the expectations of the customer. For customers that currently have concrete moats with no drainage capabilities, we recommend one of our automated VIPOR solutions. If passive drainage is preferred, we recommend plumbing the drain to an HFF Oil Stop Valve located in a vault outside of the containment area. Because every situation is different based on site-specific variables, please contact us directly and we’ll discuss your unique containment needs.
