Issue:  A consulting engineering firm contacted us regarding a wash system for their client that ran numerous grocery distribution centers and warehouses on the West Coast.  The FDA Food Safety Modernization Act (FSMA) rule on Sanitary Transportation of Human and Animal Food required their client to wash the interior of every truck entering their facility in order to keep foods safe from contamination during transportation.

They asked if we could help them design a hot water washing system that could handle multiple users at the same time since most of these distribution centers are very large and busy.  At any point in time, multiple trucks are being unloaded and loaded as fast as possible.

Solution: In response to their request, we worked with the consulting engineers and designed a very effective sanitary washing package that would ensure compliance with the new rule by combining a high-pressure VFD-controlled pumping system with a high efficiency heating system.

For this application requiring 10 stations producing 4 GPM each simultaneously, we provided two 20 gpm @ 1700 psi  pressure washing systems with VFDs and high efficiency heaters. 

The VFD system offered substantial operational flexibility since the system will only utilize the power (speed of motor and pump) to match the output demands. We designed each 20 gpm system to service up to 5 users at 4 gpm each. If there is only one user on the system, however, the pump will provide only 5 gpm, and the motor/pump will only turn at 1/5” speed to meet that demand.  The high efficiency heaters were integrated with the pumping systems to provide the correct temperature water to comply with the FSMA rule.

In addition to the pumping and heating systems, we also provided hoses, guns, reels and holders so their client had a complete sanitary washing package.  The client liked the system so much, they ordered three more systems for other facilities!

Problem: A car dealer moving into a new facility with a limited time lease. The property owner did not want them to cut concrete or substantially alter the property but the dealer needed to be able to wash dozens of cars per week onsite, contain the water and discharge it properly to the sewer.

Solution:  For a complete wash system, we recommended installing a SPT-10 Clarifier Oil Water Separator System, a cold water pressure washer with a portable hose reel, and a portable wash containment pad. This allows them to wash as many cars as possible without any major modifications to the property.  They will also be able to move the entire system to a new facility at the end of their lease. With their input, we helped them layout the system to maximize their space.

After installation of the pad, however, they noticed the concrete floor slope much slighter than originally thought and that the wash water was not moving off the pad well.  This flat slope left his staff working in standing water and the SPT-10 not being able to process the wash water properly.

To improve this drainage issue, our staff developed a low cost under layer for the wash pad which created a slight slope for the water.  We then installed this under layer and re-piped the in-take piping for the SPT-10 so the wash water flows freely.  The general manager of the facility is very pleased with our systems and service.

oil water separator

Problem: A metals dealer and recycling company had a small wash outside area with a 900 gallon in-ground concrete sump adjacent to it. The sump captured both the wash water and storm water coming off the pad. Contaminants included compressor oil, motor oil, transmission fluid and gasoline.

The company called and asked us for suggestions on how to treat the water before discharging to the sewer. The nearest building to the sump was several hundred feet away and they had very limited area inside it to install an oil water separator.

transportable equipment room

Solution: This was a perfect application for our transportable equipment rooms. To treat the water, we installed an oil water separator with an electric diaphragm pump in a 20′ long container, our TER-20. Since the client was located in a northern climate, we added insulation and a heating system to the TER-20 to guard against freezing issues.

We placed the TER-20 on a pad adjacent to the in-ground sump and it took less than a day to hook up all of the electrical and plumbing lines to make the system operational.

Using the TER-20 saved the client building costs and provided additional storage space. It also allows them the flexibility to move the entire oil water separator system to a different facility when needed.

New Locomotive Wash Bay Pump

A national railroad freight company called and requested a complete overhaul of their 40-year old locomotive wash. This 1970’s era locomotive wash system consisted of three different wash arches – a wetting arch to wet the locomotive, a second arch for soap application and washing, and a third arch with an acid wash for surface brightening.

The wash system was overhauled with to improve the following metrics:

  • Improve the wetting stage process by increasing both water volume and pressure as well as the nozzle design to apply the wetting water on the locomotive; and
  • Improve the soap application process by redesigning the nozzles’ flow patterns and volumes, increasing total flow to the nozzles, and finally adding additional pressure the process.

We started the overhaul process by removing the old soap and rinse pumps as well as the associated wiring and conduit. All of the existing control panels and associated conduit and wiring were also removed. Some equipment was retired in place to reduce demolition, re-piping and re-wiring costs. We then installed the following new equipment:

Locomotive wash bay control panel
Locomotive wash bay stainless steel control panel

Control Panel – A new stainless steel control panel was mounted, which replaced the existing four electrical panels. New conduit and heavier wire was also installed to bring it up to existing codes. The dual electric eyes were re-wired back into the new panel. New liquid level floats were installed in the storage tanks to provide both fluid level control, as well, as provide new a pump shut down safety, in the event of a low water condition in the water storage tanks.

Wetting Pump – A new 15 hp, cast iron pump was installed to supply water to the wetting arch. New, larger PVC piping as well as new heavier electrical wire was installed through new conduit to supply the proper amperage for the new higher horsepower pump.

Soap Pump – A new 15 HP stainless steel pump was installed for the new wash soap arch. New heavier wire was pulled through new conduit to supply the proper amperage needed for the new pump. The new pump was plumbed into the existing PVC piping in the pump house.

Wash Tunnel Nozzles – The existing nozzles could no longer be utilized due to flow and pressure differences from the new pumps. The existing nozzles were removed and replaced with a set of brass nozzles. A total of 42 new nozzles were installed in all three arches.

Rinse System Pump – The existing 100 hp motor and pump were removed and a new 25 hp motor and pump was set in place, aligned, and bolted to the exiting pump base.

Rinse System Control System – A new PLC-based control system housed in a stainless steel panel was installed and integrated with the existing control wires. New wiring was installed from the original motor controller system to the new control panel.

Rinse System Nozzles – The original nozzles, which were sized for the flow from the one hundred horsepower pump, were removed and new brass nozzles were installed.

The entire overhaul took less than a week to install and brought the whole wash system into the 21st century! The client has been very happy with its performance.

At, we are committed to helping our customers achieve their environmental goals and enhance their “Green” image by reducing waste and pollutants and conserving resources.

There are many “Green” benefits than can be derived from the use of efficient wash and reclaim systems. In many places, drought conditions have made water scarce and ultimately more valuable. Using lower volume washing systems and reclaiming and reusing water are extremely beneficial for the environment because it saves of large quantities of water. It also helps businesses feel more secure in that they can continue operating even under drought-imposed water restrictions.

Going “Green” is most successful when there are also good business incentives to do so – in other words, when there are significant cost savings while encouraging positive environmental stewardship.

Overall, lower water usage and recycling makes a great deal of sense since it helps to minimize environmental liability, enhance the company’s image as a responsible corporate citizen and produce significant cost savings.
