2. D.O.T. Portable Washing Systems By Hydro Engineering Inc. www.hydroblaster.com

3. THE REQUIREMENTS • High-pressure, Hot Water wash/rinse systems • Vehicle and equipment wash pads • Wash wastewater collection and recycling • Prevent buildup of contaminants and Magnesium Chloride in recycling systems • Maximize availability/minimize complexity • Meet Clean Water Act (40-CFR) provisions

4. CLEAN WATER ACT • Simply: “No water other than that from rain may hit the ground and make its way to a waterway” • Solution: “Closed-Loop, Full Recycle”

5. HydropadPortable Wash Pad Systems

6. Hydropad Benefits • No design or engineering costs • No permits and no construction • Hydropads won’t crack like concrete • Hydropads can be configured for any size wash pad and any weight rating required • Hydropads can be set in place, connected and used in just hours

7. 32’ Long X 14’ We propose a 32’ Long X 14’ Wide Hydropad System that can be expanded

8. 25 tons on three Hydropads are tough 25-tons on three points

9. Hydroblaster High-Pressure, Hot Water Washing Equipment • 4-GPM, 3,000 PSI • Hot water washing equipment that utilizes recycled water from Hydrokleen System • Electrically powered • Natural or LP gas heated • UL 1776 Certified

10. Hydroblaster Low Volume Rinse • 3-GPM, 1,000 PSI • Fresh water rinsing system • Integrated into one cleaning system wand at the wash pad

11. Remote Control Washing • Hydroblaster Remote at the wash station allows operator to select hot recycled water for washing or rinse with fresh water

12. Hydrokleen Wastewater Recycling Equipment • Solids that are larger than 5-microns are removed by the CMAFU-2 • 100 yards of filtration media automatically advances as required • No cartridge filters to buy, change and dispose of

13. The Ultimate In Recycling • HE/5000 performs • Oil coalescing and skimming • Fine solids polishing to less than one micron • Pressurizes filtered water back to the Hydroblaster

A certified copy of the test results is available by mail from Hydro Engineering, Inc.

15. Desalinization • Our integrated desalinization system clarifies many gallons of water per day, constantly removing trace contaminants • Magnesium Chloride and other contaminants will be removed

16. complete washing Your complete washing and recycling system can be located just inside of your building

17. No Building Space?Use a Hydrosite Hydrosite Corrosion Control Package

18. Inside . . . Drive thru wash bay No need to tear up concrete
