Testimonials

Customer reviews

As an earth mover I have installed many different makes and types of tanks over the past 15+ years. Ri-Industries tanks are one of the strongest that I have seen. Their service from point of sale to delivery is most impressive. Their delivery team always go out of their way to deliver even in rough terrain or tight spaces. These are some of the reasons why I have installed one of their tanks on my new home – I am very pleased with the product.

David Ayres

I have been a customer of Ri-Industries for over 30 years and the staff have always been polite, friendly and very helpful.

They have great products that are of a high quality and reliable. I have no reason to try and source your range of products from anywhere else.

We have had two 12000 litre water tanks and one septic tank delivered to our new build at The Range by Ri-Industries. One water tank was almost impossible to place but in discussions with Ri, they organised to send out their best tank delivery guy to assess the situation. He was brilliant. No fuss, down to earth and very professional – he dropped it in to exactly the right spot.

I have had a RI Industries Aerobic Septic system installed at my house and it has been a great system !
When it’s installed and commissioned by the right people there are no hassles. Any enquiries I’ve had since I have rang and got
the answers I need.

Ben Moloney

I needed a 200mm saddle riser added to my existing septic tank of theirs installed a few years ago and Ri-Industries was quick to get everything organised and managed to get it to me within a week of payment. The delivery driver made the whole process when dropping the item off very easy and helped me get it to exactly where I needed. I can’t recommend this company any higher!

Christopher Burgon

I have always received excellent support and service from the entire team over the past 20 years.
