Commercial water systems
Packaged pumping, pressure boosting, reuse, controls and lifecycle support for commercial water infrastructure.
Technical Solutions
Specify the right water system
Practical application guides for Australian projects. Pick the water challenge, open the matching product range, then request a sized quote.
How it works
From site problem to product specification
1. Define the application
Rainwater, stormwater, wastewater, grease, trade waste or drainage. Start with the water challenge, not the SKU.
2. Match the product range
Jump to the catalogue for that application, filter by family, and open specs, drawings and BIM where available.
3. Get a project quote
Send site details, PE load, catchment or council conditions. The GRAF team sizes and quotes the right configuration.
Applications
Choose your water challenge
Rainwater harvesting
Underground tanks, filters and pump packages for homes and commercial sites.
Stormwater management
EcoBloc detention, infiltration and treatment systems sized for Australian WSUD and council requirements.
Data centres water strategy
Closed-loop stormwater capture, treatment, detention and reuse for cooling feedwater and fire reserves.
Rainwater treatment
Stormwater treatment covers EcoPure 200, EcoClean, sedimentation and separators.
Wastewater treatment
Domestic and commercial sewage treatment, septic and holding tanks for dwellings through to multi-dwelling loads.
Grease separators
Under-sink, Sapphire and Grease Arrestor SC for commercial kitchens and FOG-contaminated wastewater.
Trade waste pretreatment
SC pits for acid neutralisation, dilution, settling, lint, cooling and oil-water separation.
Surface drainage
HAURATON channels and gratings for civil, landscape and hardstand runoff control.
Pump stations
Wet wells, pump-out tanks and packaged commercial pumping systems for sewer rising mains, stormwater and site drainage.
Technical support
German engineering with Australian assistance - documents, BIM, DWG and Revit data where available.
Design tools
Sizing calculators for rainwater, stormwater detention, pump selection and pipe friction.
Sponge city
How retention, harvesting and infiltration work together
Green roofs, swales, permeable pavements, underground tanks and EcoBloc infiltration turn a hard city into a sponge. Use this as a conversation piece with councils and designers, then jump into the matching GRAF ranges below.
Project support
Need a sized system, not a catalogue browse?
Send catchment area, PE count, load class, council conditions or drawings. We will recommend the right tanks, pretreatment, drainage or pump configuration for the site.
