Industrial Pressure Washers for a Heavy-Duty Clean

Your Problem: You manage an oilfield service company with frac equipment and drilling rigs, so you’re dealing with a ton of crude, grease, baked-on grime, the works.

Portable Pads and Wash Racks: Move-In, Wash, Move-Out

Your Problem: A pipeline contractor needed to clean excavators and trucks across multiple states. Your project is mobile — fleet vehicles, heavy equipment, wash locations keep shifting. Permanent infrastructure isn’t an option. Here’s what you need to know: Can we wash heavy equipment anywhere without construction or plumbing? 

Evans Solution: Yes. Our portable wash pads and racks are rugged, self-contained, and designed for movement. Constructed in marine-grade aluminum or galvanized steel, these systems support up to 80,000 lbs, require only a flat surface and power, and integrate seamlessly with Evans water-treatment systems. Pair it with an Evans Mechanical or Bio System for a closed-loop setup that saves time, cost, and compliance headaches.

FAQ:

• Does it need major plumbing? No. It’s minimal site prep, just flat ground, and access to power is enough.
• Can I rent or buy? Both options are available, so it’s perfect for temporary jobs or long-term assets.
• What if the location is really remote? Doesn’t matter. Concrete, asphalt, or unsuitable ground – we can do site prep to make it work. Plus, we offer 24/7 equipment support. 
• Is it compliant with national environmental regulations? Yes, it’s fully designed for containment and recycling.
• How fast can we rent a portable wash pad on site? Our service team can deliver and install turnkey pads on short notice.

Wash Water Treatment Systems: When You Can’t Just Let It Run Off

Your Problem: You’re a power-generation contractor in West Texas with a heavy equipment fleet on a remote site washing off diesel, drilling-mud and oils from your service trucks. Local discharge is restricted. Local discharge is restricted, so how do you treat wash water and stay compliant? What system handles greasy water, mud, and oil reliably?

Evans’ Solution: Our Evans Bio System (EBS) is built for exactly that. It’s skid-mounted, marine-grade aluminum, self-contained, and forklift-ready. It uses biological compounds to rapidly degrade hydrocarbons like oil, grease, diesel, and drilling mud into harmless water and carbon dioxide. The EBS installs fast, runs with minimal oversight, and recycles or safely discharges treated water, which keeps your operation compliant and on schedule.

FAQ:

• Is installation difficult? Nope, the Evans Bio System is designed for easy installation on site, so you’re up and running fast.
• Will it handle heavy suspended solids like clay or floc? For heavy solids, we recommend pairing it with the Evans Mechanical System for full treatment.
• What do I get with wash water treatment system rentals? A full turnkey unit, including service support by Evans technicians, plus chemicals and consumables support.
• Rental or purchase? Both are available, depending on your project length and budget.

Mechanical Filtration Systems: When Suspended Solids are Your Worst Enemy

Your Problem: A Gulf Coast construction contractor is cleaning large tracked excavators and encountering mud, flocs, silt and oil. It’s everything at once. The wash water is dark, heavy, and full of solids. Now, you’ve got clogged drains. You ask: what equipment filters this mess so you can discharge legally? Do you have a system that handles clays, silts, flocs, oil & grease?

Evans Solution: Absolutely. Our Evans Mechanical System (EMS) is purpose-built for this type of tough contamination scenario. It integrates bioremediation with sand and carbon filtration, available in marine-grade aluminum or poly materials. The EMS ensures that you meet environmental discharge standards so your site can keep running. 

FAQ:

• Can this be combined with the bio-treatment system? Definitely, suppose you have both organic contaminants and heavy suspended solids. In that case, we can tailor a solution that cascades treatment (bio first, then mechanical), saving time and cost with an end-to-end treatment process that removes solids and organics. 
• Is it compatible with other Evans equipment? Yes, it’s designed to pair with our pressure washers, chemicals, and wash racks.
• Can it integrate with my existing wash pad? Absolutely. Evans systems are designed to connect seamlessly.

Oil/Water Separators: Pre-Treatment Made Clean

Your Problem: You’ve got a mid-sized transportation company that operates a fleet of heavy trucks all over the Midwest. After washing down you’re left with oily wash water and settling solids. You need to treat it before it leaves your yard per local discharge rules. So, how can we separate oil efficiently on-site without overhauling our whole setup?

Evans Solution: Our ‎Evans Oil/Water Separator is a 3-compartment V-bottom design built in marine-grade aluminum for durability. It uses gravity flow to separate oil and solids, with an optional float-activated discharge pump. Ideal for pretreatment, it helps meet environmental standards while reducing load on downstream systems.

FAQ:

• What are the available sizes? 500, 750, and 1,500-gallon units.
• What contaminants does it handle? Oil & grease, mud, clays, silts, and flocs – it’s designed for both oil and sediment separation.
