GRAF Australia understands the unique challenges of preserving water in the Australian climate.
Our mission is to solve these issues by providing a range of accessible water management solutions that keep water clean, while working to collect and protect every drop.
Our passion for sustainability and a cleaner Earth means that we are constantly innovating to find new ways to keep contaminants out of our waterways. We turn plastic waste into plastic water treatment products, in turn creating a pattern of reuse, recycling and regeneration.

On-site detention
OSD tanks for Australian peak-flow rules
New residential and commercial sites often need on-site detention so stormwater leaves the lot within council discharge limits. Specifiers call that an OSD tank, a detention tank, or modular stormwater volume under the pavement.
GRAF Australia supplies EcoBloc modular crates and Carat detention tanks for those briefs. Start with the detention guide for meaning, EcoBloc versus vessel tanks, and how to quote locally.
Project guides
Australian answers for tanks, OSD and grease
Practical how-to pages with diagrams, FAQs and paths to quote GRAF Australia products. Start with underground rainwater tanks, then branch into detention, grease and local supply questions.
