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 and above-ground 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.

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 and pump-out tanks for sewer rising mains, stormwater and site drainage.

Design tools

HAURATON RECYFIX PRO product finder and upcoming sizing calculators for project design.

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.
