Cedar Grove Flood Damage
AES Installation
Cedar Grove Irrigation Area

In 2012 a devastating flood completely destroyed the camp ground facilities at Cedar Grove Camping area.

We were engaged by Qld Parks & Wildlife to design a new wastewater facility for the camping grounds.

Most of our design work is for individual clients who are building homes, doing extensions or upgrading existing systems.

In commercial applications we have designed wastewater facilities in remote locations for Qld Parks & Wildlife throughout Qld.

This is a list of some National Parks and State Forests where designs have been completed.


We hope this gives you an appreciation of our extensive design experience.
