NEW DECONTAMINATION DIP TANK TO BE INSTALLED AT STATELINE

The Utah Division of Wildlife Resources announced a new method for decontaminating boats. It's called a Clean Wake Dip Tank (Clean Wake LLC). The idea is to reduce the time to decontaminate a boat, especially complicated boats like wake boats. They unveiled the dip tank today in Ogden, Utah. It took about 7-8 minutes to lower the boat into the tank, start the engines, and fill and empty the ballast tank. The plan is to put this first-of-its-kind dip tank at the Stateline ramp and have it running May 1st. They only purchased one of these tanks, (at a cost of 800K). They plan to see how the tank performs this Summer and could add additional dip tanks to other ramps at Lake Powell in the future, at a substantially lower cost. I found it interesting that the water temperature in the tank is only 110 degrees. Not the 140 that has been publicized for the past 14-15 years. I was told that 110 is sufficient to kill AIS. Hopefully this works and shorter lines await us in the future. Here is the press release from earlier today.

SALT LAKE CITY — The Utah Division of Wildlife Resources, Clean Wake LLC, the National Park Service at Glen Canyon National Recreation Area, the U.S. Bureau of Reclamation and other partnering agencies are excited to announce a new first-of-its-kind dip tank method that will revolutionize boat decontamination in the fight against invasive quagga mussels.

The idea for this new decontamination method had been discussed internally within the DWR for nearly a decade, but had remained an abstract concept until almost five years ago when Garrett Atwood — creator of the new patent-pending dip tank and founder of Clean Wake LLC — took a boating trip to Lake Powell.

“I was waiting in the quagga mussel inspection line with other boaters who were trying to leave Lake Powell,” Atwood said. “I watched as the DWR staff worked in extreme heat to decontaminate boats of all shapes and sizes, many of which had intake systems that were far from standardized. It seemed like a time-consuming and challenging process, and I thought there had to be a better way.”

Atwood began a collaboration with the DWR aquatic invasive species team. After nearly a year of engineering and fabricating, the dip tank was created, complete with a tank, pumphouse, and heating and filtration system. The new tank will be transported from Ogden to Lake Powell, where it will be installed at the Stateline Launch Ramp at Wahweap Marina and will be operational beginning May 1.

Rather than requiring personnel to climb around and under boats to manually spray hot water during inspections and decontaminations, the dip tank allows boaters to back their watercraft into the 14-foot wide, 5-foot deep tank of 110-degree water to more effectively and thoroughly flush complex intake systems. The dip tank includes built-in guiding tracks to help boaters back their watercraft into the tank. The filtration and pump system will turn over the water in the tank every two hours to keep it clean. The whole decontamination will only take about five minutes.

“This new system will be a tremendous asset in our efforts to stop the spread of invasive quagga mussels,” DWR Aquatic Invasive Species Coordinator Nate Owens said. “It will involve decontaminating boats with complex systems much faster, will require less training for our staff, will be more effective at ridding complex systems of quagga mussels and will ensure less damage to boats. We are so grateful for the ingenuity of Clean Wake LLC, our partnership with various agencies and the legislative funding and support that have made this possible. This is the first time this method is being used anywhere in the U.S., and we are excited to partner with the National Park Service at Glen Canyon National Recreation Area to create a better experience for boaters at Lake Powell.”

While the new dip tank will be utilized beginning this summer at Lake Powell, it will primarily be used for wakeboard boats with complex systems. The standard hot-water spot decontaminations will still be utilized for other boats leaving Lake Powell. The dip tank and standard decontaminations are free to boaters.

The dip tank has a water filtration system. I think the designer of the dip tank said the water is filtered every 3.5 hours. I would imagine the water getting some oil and gas in it after a few dozen if not hundreds of boats. Not sure if they plan on filtering the oil and gas out of the water. I would suspect the oil to rise to the top. I guess they could skim it off, but I also suspect it will get a little greasy. Might need to wash the hull off with some Dawn after the decon is done?

I watched the video Wayne posted. This is a great idea. My Malibu takes at least 45 minutes to decon the way it has been done in the past. Huge improvement if it can be done in under 10 minutes which should be very realistic with this system.

This is an absolutely wonderful attempt to combat a huge issue for those who would like to spend just a few minutes at the decon station rather than 45 minutes to an hour. However, what considerations should be taken in order to avoid the bearings on your trailer getting compromised? I already pack grease in mine after a few times long trips and launching.
