Water is our most precious natural resource and something that most of us take for granted.

About CMW


CMW Concrete Tanks are a well established, local company owned by Rodney Green. Rodney’s father, Norm Green, began building concrete tanks in the Northern Rivers, New South Wales, in the early seventies, being one of the pioneers of the industry. Rodney started working for the family company in 1980 and has been in the concrete tank construction industry ever since. Now Rodney’s own children have also started working in the family business, keeping the tradition alive.

CMW Concrete Tanks are one of the most established and well-recognised concrete tank builders in Northern NSW and take pride in it’s reputation with local suppliers, builders, plumbers and construction company’s. Through our years of experience we have developed a sound construction process and with superior raw materials, backed by stringent quality controls we ensure that every concrete tank is constructed to the highest quality standard. CMW has an extensive range of tanks available at competitive prices that will suit any family and budget and a great customer service record.


Water is our most precious natural resource and something that most of us take for granted. We are increasingly becoming aware of the importance of water to our survival and its limited supply, especially in such a dry continent as Australia. Rainwater tanks can provide a renewable supply of natural, soft, clear and odourless water that can be used for a range of purposes. In some areas it may represent the primary source of household water.

Innovative Solutions

To be honest, we just love when a new client challenges our creative and technical thinking with a challenging project at hand! We foster innovation and creativity, alongside experience and skillful execution, as part of our culture. Because of this, over a long history, many clients have selected us for unorthodox, complex projects in which engineering and designing enigmas produce innovative, industry defying solutions.

As an official fro North Dakota’s state government, I want to thank the Builderry construction company. On behalf of the citizens of the state, we’re so grateful for this new, innovative building! This allows North Dakota to hold its legislative operations in a contemporary, progressive architectural environment!

This bridge project was funded by small and medium business of Rhode Island, as well as by its private citizens. After the hurricane hit our shores recently, we all were concerned for the Okaloppo river not having a proper landline connection. But now, after Builderry company finished the project, the county can enjoy its new, beautiful infrastructure!

Benedict Arnold

A a part of our expansion effort, we decided to open a location in the state of Georgia. We were impressed, to say the least, when we saw the bold design concept, penned by Builderry company. But the completed shopping mall’s building, finished 2 (!) weeks earlier than planned, just left us speechless and delighted!
