This Hydrosite watercraft decontamination system was installed in 2007 and is still operating today. This is just one of many systems supporting aquatic invasive species (AIS) prevention at Glen Canyon National Recreation Area, Utah/Arizona. The system is connected to utilities (power, water and gas only, no sewer) that were routed to a parking area. This dual Hydropad portable wash rack system satisfies high volume decontamination demands of watercraft visiting Lake Powell.

Hydro Engineering, Inc. started pioneering mobile pressure washer watercraft decontamination systems in 2008. Products have evolved and innovative solutions continue to address new aquatic invasive species (AIS) control requirements. A Hydromat wash water containment mat with a trailer mounted pressure washer that includes wash water capture and onboard wash water filtration and recycling is shown.

This Wash rack system is all above ground. It includes a 20' wide by 40' long patented Hydropad portable wash rack , and a Hydrosite portable equipment building. Aquatic invasive species decontamination is performed on the portable wash rack.. Wash water is collected, treated, filtered and recycled back to the decontamination system to be used over and over in the process. System conserves water because no wastewater is discharged. This system was deployed in 2008.

Hydrosite integration with the patented Hydropad portable wash rack provides effective watercraft decontamination and wash water filtration and recycling. Aquatic invasive species contaminates are rendered inert, then separated and removed as solid waste. Liquids are filtered and recycled by this zero wastewater discharge system. Modular and all aboveground portable wash rack simplifies installation and relocation if required.

Picture these mussels inside the out drive and engine. The smaller mussels are taken into the engine where they grow to full size and plug the waterways. You then overheat and burn up your engine. Our decontamination systems can remove them easily.

Sea planes, amphibious float planes and those with strait floats can transport aquatic invasive species (AIS) from one water body to another. Items which protrude from the floats, rudders, wheels, etc can gather and hold AIS, transporting it to the next landing site. These pontoons also have compartments which maintain the buoyancy of the craft, water seeps in requiring frequent pump out of the compartments. If not done prior to takeoff, this water can carry AIS to the next location where water is evacuated.
