Products and services

Small wastewater systems from GRAF can be flexibly adapted, to meet stricter discharge values in water protection areas, for example. Options such as the external control cabinet, convenience package or cover suitable for vehicle loading allow the systems to be adapted to your individual needs.

Plastic storage systems have become a popular solution for rainwater infiltration and retention. Infiltration ditch bodies require very small amounts of space compared with gravel ditches or drainage pipes. They offer a large infiltration volume for a low weight. Other benefits of GRAF infiltration modules include their high load capacity and durability.

GRAF rainwater tanks are designed for a long life. Special materials ensure a long-lasting attractive appearance. The tank material is 100 % recyclable and is therefore good for the environment.

EcoBloc Inspect flex

EcoBloc Inspect flex

EcoBloc Inspect flex for rainwater infiltration, retention or rainwater harvesting. To save space during transport, two EcoBloc Inspect flex modules are stacked one inside the other. This halves transport costs and CO2 emissions. The EcoBloc Inspect flex is easy to transport and install. The modular system structure requires few accessories. The system size and loadbearing can be adjusted individually to suit requirements of traffic and of non-traffic area.

Klaro E Professional

Klaro E Professional

The GRAF SBR wastewater treatment system Klaro E Professional works according to the principle of SBR lifting technology. No live parts need to be installed in the tank. All movement processes are performed by three air lift pumps, which are operated using a compressor. The compressor also provides the plate ventilator on the bottom of the SBR reservoir with air.
