Tanks for the Commercial and Mining Industry

Over recent years there has been a much higher demand for Rainwater Storage Tanks used in the Commercial Industry.  This is due to a number a factors, being stormwater detention, rainwater harvesting, storage and reuse.

Most Commercial sites have maximised the land usage meaning that below ground is the only option for the Rainwater/Stormwater detention Tank.  More often than not the Tank is in the car park, with heavy vehicular traffic.  Each of our W8 Tanks comes with a site specific Engineers detail and installation certificate (if required).

Our Tank sizes range from 20,000 litres to 90,000 litres and quite often multiples are required. We have several Engineer designs which range from our Standard Tank which carries passenger vehicular traffic to a W8 wheel loading.  Most importantly, we can Engineer design to suit any requirements. With our Tanks being constructed on site, we can customise all inlets and outlets to suit specific plumbing requirements.

Our Tanks are fast becoming a preferred option over the Humes RainVault System as our Tank is built as a complete unit unlike the Humes RainVault which requires joining and sealing of each of the sections.  This increases plumbing costs and reduces its reliability with the numerous joins.  The Humes RainVault is for non-potable Rainwater only which reduces its reuse potential.  We are also very competitive in our pricing and our W8 wheel loading Tank is usually less expensive then the Humes RainVault System, making the decision to install our Tank the best option in every instance.

Our Tanks are constructed onsite and we travel all over Eastern Australia servicing all Industries including the Mining Industry.

Occupational Health and Safety

We have continually reinvested into our Business, ensuring that we have the Newest and Safest Equipment.  We have spent the past 30 years refining our construction methods, reducing the manual handling of our large formwork, ensuring our Workers Safety.

Our Occupational Health and Safety practices and our Safe Work Method Statements etc., have been scrutinised by Government agencies and large National Commercial Builders and we have been commended on our Safe Work Place Practices, our SWMS, Equipment Maintenance and Certification.

  • Our 90,000 litre tank is fantastic for washing our buses, as it leaves no streaking of spotting on our paintwork.  Water restrictions no longer effect our ability to clean our fleet and the best part is it’s free!

  • Thank you very much for the recent installation of our 20,000 litre in ground concrete water tank you built on site. It was a real pleasure to deal with you. Not only did you do what you said you would but you also did it in a friendly, professional, ethical and very efficient way. I was very impressed with your expertise and state of the art equipment which allowed you to construct a high quality tank in a relatively short time without fuss or disruption to the other construction works being carried out on site at the time. So thanks again and good luck in your business, but with over thirty years of plying your trade you probably don’t need luck.

    Peter & Krystyna

  • We recently contacted you and requested the design and engineering details of the

    two water tanks Coolamon built on our property in 1989 and 1991. Thank you for providing us with the relevant Engineer’s drawings and specification. lt is pleasing to know that we could still contact the company that built our water tanks over 20 years ago and source the information we needed.

    Mr Howe

  • Thankyou to both you and Richard & Co. for such a professional and painless experience.

    Love the new tank!

    Graham & Rebecca

  • Richard and his crew built a 20,000 gallon Tank for rainwater for my house and a 10,000 gallon bushfire reserve tank as well.  Richard has great attention to details and answered all my queries in a professional manner.  With these tanks in place I have great water security for my home and as a member of the local Rural Fire Brigade, I understand the necessity of fire protecting my property for my families safety.  These tanks will last a lifetime and are a great investments for my property.


  • Fantastic to watch – know their trade backwards.
