We offer a complete line of high efficiency, stainless steel above ground oil water separators that will remove nearly all free and dispersed non-emulsified oil and settleable solids from the waste stream.
Featured
We provide heavy-duty, multi-stage, closed loop and hybrid wash water treatment systems to clean
the wash water so it can be used over and over, saving thousands of gallons of water per year and
associated discharge costs.
The system can be designed in two ways. The first option is a complete closed-loop system with no
sewer discharge. With these systems, 100% of the water used by the pressure washers,
demuckers, and water cannons is recycled. As water is carried off with equipment, evaporated into
the air, or blown off the wash bay due to wind, make up water is added to the system to offset these
losses.
The second option is a hybrid closed-loop system. In our hybrid systems, water is recycled for the
de-mucking and/or water cannons, but fresh water is fed to the pressure washers. If the pressure
washer adds so much water to the system that all water storage tanks are filled to the maximum
level, any additional excess water is treated with carbon and sent to the sewer system.
Both systems are part of our comprehensive approach to water treatment that includes solids
settling, oil and grease removal, water filtration, odor control, and final polishing.
Stage 1 – Solids Settling
We help you develop site-specific solutions to eliminate as many solids as possible before the water
goes to the next stage of filtration. Solutions include sumps, basins, trenches or screening systems
that are custom-designed for your facility, washing processes and maintenance procedures.

Stage 2 – Oils, Grease & Solids Removal
After the coarse solids settling, the water is processed through a multi-compartment stainless steel clarifier oil-water separator, which separates out smaller suspended solids, oil and water. In the first compartment, free oils float to the surface. In the second section, the stainless steel clarifying plates remove coarse amounts of oil and as much Total Suspended Solids (TSS) as possible. The angles of the non-clogging plates are 55° which allows solids to slide down the plates into the solids hopper, where they can easily be pumped out. Next, the water goes through our coalescing media which removes essentially 100% of all free and dispersed non-emulsified oils so the FOG effluent concentration can be as low as 5 ppm.

Stage 3 – Water Filtration & Odor Control
After the clarifier oil-water separator, the water is pumped though several filtration steps including multi-media (sand, gravel, anthracite), blended activated carbon, polishing filter, and corona discharge ozone. These filters reduce odors and any contaminants to fewer than 10 microns in size, including emulsified oils, waxes, and other volatile organic compounds. Media, carbon, ozone and water storage volumes are typically customized to meet your particular application.
Stage 4 – Final Polishing Filtration
In the final polishing filtration section of the CT system, water is pumped from the storage tank
through a blended activated carbon bed (customized for your application) and then through a final
cartridge filter. When the pressure washers require water, the pump will provide clean, treated
water, free of particles, substantially all emulsified oils, waxes and other volatile organic compounds.

Frequently Asked Questions (FAQs)
What pressure washer is best for cleaning locomotives?
Locomotive cleaning requires industrial-grade, hot water pressure washers with high flow and adjustable pressure. Wash Bay Solutions designs pressure washers specifically for rail applications, providing the power and durability needed for daily locomotive washing.
Can pressure washers be used instead of a full locomotive wash bay?
Yes. Many rail facilities use heavy-duty pressure washers for flexible, manual cleaning. High-volume operations often combine pressure washers with automated wash bays for maximum efficiency.
Do locomotive wash bays require water recycling systems?
While not always required, water recycling systems are strongly recommended. They significantly reduce water usage, lower operating costs, and help rail facilities comply with environmental regulations.
Can Wash Bay Solutions retrofit existing locomotive wash facilities?
Yes. We design retrofit solutions for existing wash bays, upgrading them with modern wash arches, pressure washing systems, and water reclaim technology.

For clients who have to leak test vehicles to ensure that there has been no water intrusion after manufacturing or modifications, we have developed a complete leak testing system. Custom engineered to fit your facility and testing protocols, our water intrusion / leak testing systems consist of containment pads, test arches, a water supply system and a fully automated filtration system designed to remove contaminants from the test water so that it can be re-used for a period of time prior to disposal or discharge to the sewer. Designed for commercial and industrial applications, all features of the system are manufactured to insure superior performance and minimal operating requirements.
The containment system consists of a water containment pad constructed of steel or heavy-duty PVC.
Sized to fit your facility and test vehicle, these pads feature entrance and exit ramps and drive over and/or pedestrian grating, if desired. Custom-sized water-proof canvas canopies, PVC curtains or Fiberglass walls are installed on the pad to minimize overspray.
The leak test system is built to fit into the containment system so there is no overflow. Depending on the client’s needs, the leak test system will include multiple side and overhead spray arches, vertical spray posts, and undercarriage spray bars, positioned to provide optimal coverage. The spray test will last for a client-specified period of time and can be easily controlled by a driver with a remote start/stop key fob.
During the water intrusion / leak test, water is automatically pumped from the containment pad through an initial filter to remove any minor solids and contamination. From there, water is pumped into manifolded water management tanks. The tanks provide enough water storage to permit proper water balancing during the testing period and the water recovery time. The tank system is equipped with level switches to protect the pumps and to automatically provide for fresh water make-up due to evaporation or drive-off losses. From these tanks, water is pumped back to the test arches, when needed.
In most leak test applications, the contaminants are minimal so this pumping and filtration cycle can last a considerable amount of time. When the water becomes too contaminated to re-use, however, the water can be pumped out or processed through additional filtration and discharged to the sewer.
