About GRAF Australia
Engineering sustainable water management systems for Australian sites.
More than 60 years of German water-management and plastics engineering, combined with Australian manufacturing, technical support and application expertise.
GRAF Australia
Capture, protect and treat water at every scale
GRAF Australia provides systems that harvest rainwater, manage stormwater, treat wastewater and control grease and trade waste. From a backyard tank to a civil detention field, we help specify systems for site conditions, hydraulic requirements, council and water authority requirements, and the Australian climate.
We combine the legacy of Otto Graf GmbH with local manufacturing and a national warehouse network. That means German-engineered platforms, adapted and supported here for drought, flooding, contaminant control and long service life.

Circular materials
Products born from recycled plastic
Across the GRAF group, post-consumer plastic is processed into the tanks and modules that protect water on site. Using recycled feedstock cuts virgin polymer demand while keeping the strength and lifespan Australian projects need.
GRAF Upcyclen is produced at the GRAF Competence Centre for Raw Materials and is used across a large share of GRAF environmental products.
