 Trustindex verifies that the original source of the review is Google. Steve & Karen (family business) did a fantastic & professional job in replacing my old 1,000 gallon galvanised rainwater tank at Hectorville for a competitive price. Steve helped me to install a new support structure for the rainwater tank and wouldn’t hesitate to recommend them. If you need a rainwater tank don’t waste your time & just go with the best. Thanks, Tony

 Trustindex verifies that the original source of the review is Google. Steve and Chris from H2Orainwater tanks did a fantastic job of installing our rainwater tank, including supplying the pump and connecting to the plumbing loop that was installed when we renovated our house. We can now use rainwater at 3 seperate taps. They custom made the tank to fit into a specific area and in a colour that matches the house cladding, which blends in perfectly. From quote to completion Steves correspondence was fantastic. I highly recommend using H2O rainwater tanks for a highly professional job at a great price.

 Trustindex verifies that the original source of the review is Google. H20 Tanks were reliable and professional.
We need our Bushfire tank relocated. The area we wanted the new tanks built was under a deck, which meant the tanks had to be built on site. Steve and Karen came to look at the job, provided a more than fair quote (we had several quotes, all considerably more expensive). The work was completed in just two days. It was a highly satisfactory experience and we have no hesitation in recommending H2O to others.

They gave a great quote, turned up on time, removed the old tank and did a great job. And were a very nice, friendly couple. Cannot recommend highly enough.

 Trustindex verifies that the original source of the review is Google. Highly recommend these people to install your next rainwater tank.
We had a old tank that was lined with cement on the floor and walls that needed replacing in an awkward spot but this was not a problem to Steve and Karen.
If it was not for these two I fear the cost of replacing the old one may have just been to much as we would have needed a crane to remove the old one and put the new one in place.
Thanks so much Steve and Karen we would definitely have H20 Rainwater tanks install another tank for us.

 Trustindex verifies that the original source of the review is Google. Steve, Karen and family did an absolutely outstanding job! We had to replace our 1955 concrete-lined 18,000 litre steel tank located in a tight place with difficult access in Bridgewater. We needed demolition and removal of the existing tank and an on-site build - which not many companies offer. From initial contact to completion they were great to work with – thoroughly professional and experienced and dedicated to the task in extreme conditions. Communications were excellent and their teamwork brought the job to completion rapidly and without drama. We appreciated their eye for detail and their positive and friendly approach. We couldn’t ask for more and recommend them very highly.
