  • "Thank you for your service & prompt delivery"

    Steve Monteath
    I would like to take this opportunity to thank the driver who delivered my water tank today. You are a lucky company to have such an employee. I have spent over 40 years in education & policing & it is an honour to come across young men who stand proud & tall & are a credit to themselves, their families & their employer. The water tank is on site & the pump arrived whilst the driver placed it into position. Thank you for your service & prompt delivery. I will be passing on your contact details to friends & family advising them of your service & the 'quality' of the product. Once again thank you, Steve Monteath
  • "The Driver Nathan was very competent"

    Mark R from Robertson, NSW
    To The Manager, I recently had two water tanks delivered here at Robertson by your Company, The Driver Nathan was very competent and also keen to get on with his other deliveries so we didn’t get to thank him as well as we hoped. Please pass on our many thanks to him. Thanks once Again, Mark R, Robertson, NSW
  • "well-oiled machine"

    Guys I am in the process of buying a 22,700 water tank. I would like to bring to your attention one of your employees Mr Adam Briggs. I have asked advice about many different issues & this guy has replied promptly, given great advice & has been a pleasure to deal with. I work for National Parks & look after Sydney Harbour, I have staff & know the importance of having good staff. This guy is an asset to your company. The overall make up of your company I can see already is a professional well-oiled machine. Well Done. Regards, Darren
  • Everything was done and dusted within ½ hr of the off load and the driver was on his way. Perfect.

    Hi Russell,
    Thank you for my tank received yesterday as advised. The comprehensive instructions and information available on your web page enabled me to prepare the site and ropes for the tank prior to delivery. Everything was done and dusted within ½ hr of the off load and the driver was on his way.  Perfect. By the way, your driver Greg. He denied us the pleasure of his company to share a tea break with us in his haste to get to Brisbane. We hope he made it before sunset.
    A very pleasant and stress free experience.
    Thank you.
    Regards, Paul
