Comments from Our Customers

  • Mike Annear, F-9AX Trimaran Tropicbird

    After 3 months of sailing around Darwin, I am now living on the boat on lake Macquarie NSW. Your watermaker is still going strong!

  • Robin and Diane on board SV Sortilege

    We have been using this amazing water-maker desalinator for just over a year on board our catamaran which we live on permanently. We have been very impressed with its easiness to set up, reliability, and quality of the drinking water it produces [even from brown river water]. We run this unit in conjunction with our Honda 2kva generator and after an hour and ten minutes of running we have 8o litres of pure drinking water that tastes as good as or better than rain water. It comes with easy to follow instructions and the team at H20 On The Go have always responded to any of our questions or queries promptly. I wouldn’t hesitate to recommend this unit to anyone who wants to be independent on Marina’s or Caravan Parks to get their safe drinking water

  • Renato Daniele, Eco Synergy Developments PTY LTD

    I’m in the midst of a desalination research project, focused on sustainable building materials derived from seawater. A unique material, sustainably sourced, made reactive without carbon admissions, opposed to current Industry practice. I purchased a desalination unit from Jo & Pete to conduct my research and found their input plus the quality of the desalination unit to be impeccable. Would Highly recommend their equipment/service for any application, with the peace of mind their after sale backup is second to none… A pleasure to deal with!

  • Edjargo Marine, Fremantle WA

    Mate we are absolutely wrapped with the desal unit you supplied our vessel and will be highly recommending them to all our fellow owner/operators! Cheers!

    We could not be happier with our H2O on the Go watermaker
