CD3 Water Removal Study:

University of Minnesota’s Minnesota Aquatic Invasive Species Research Center (MAISRC)

Key conclusions:

  • Despite compliance with standard drain plug regulations, residual water remained in all boat types and in all compartments examined; however, the risk of residual water was reduced by using the CD3 Station vacuum.

  • While not 100% effective for all boat types, this demonstrates potential value to reduce the risk of AIS spread between lakes by promoting a more extensive and comprehensive approach to water removal. 


Minnesota Case Study

Five Waterless Cleaning Stations 2017-2018 Pilot Outcomes


 

Executive Summary

Clean-Drain-Dry-Dispose (CD3) Waterless Cleaning Stations provide free tools empowering day-boaters to take action to prevent the spread of Aquatic Invasive Species (AIS). The stations are a waterless, free, user operated cleaning equipment including wet/dry vacuum, blower, and tethered hand tools. Internet connected, the stations log use, maintenance, and functionality.

Successfully piloted in Minnesota at five locations, CD3 Station software logged over 6,500 volunteer AIS prevention actions taken by boaters (approximately 2,200 watercraft). Accessible 24/7, CD3 Stations have been proven to extend AIS budgets.

CD3 Station Sites: five locations spanning urban to rural geography & watercraft users:  

  1. Lake Minnnetonka, Spring Lake Bay Hennepin County

  2. Lake Minnnetonka, North Arm Bay Hennepin County

  3. Bryant Lake, Three Rivers Park District  

  4. Pike Lake, Canosia Township

  5. Lake Riley, City of Eden Prairie

Launch Managers: Municipalities, township, park district & county,

Targeted AIS:  zebra mussels, eurasian water milfoil, starry stonewort & spiny waterflea

Over 28,400 Total Uses in 2 Combined Field Season

Key Outcomes

  1. Highly visible AIS engagement and awareness tool for visitors

  2. 24/7 accessible equipment provides $50,000+ value, if paid $12/hr/year

  3. 7+ year asset at low operational cost of septic & electrical ~ $250/season

  4. Use metrics and maintenance alerts via MyCD3Station.com software

  5. Technology options for boaters to CD3 “check in” and “check out” at a launch
