Wastewater Treatment.
GRAF offers individual wastewater treatment solutions, for volumes from 0.5 to 750m³ per day, in our wastewater tanks or as solution for existing or concrete tanks according to customers' requirements.

Stormwater Management.
Graf Eco-Bloc infiltration system, an innovative solution for on-site stormwater detention made entirely of 100% recycled plastic. A sustainable, eco-friendly alternative to traditional concrete detention tanks.

EcoBloc system

Plastic storage systems have become a popular solution for rainwater infiltration and retention. Infiltration modules 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.

SBR wastewater treatment systems

Because of their low weight, small wastewater treatment systems made of plastic can be installed without heavy equipment. This means that they can be easily transported and installed in locations that are difficult to access. Plastic wastewater tanks also have smooth inner surfaces, which makes them easy to clean. What's more, plastic tanks are 100 % waterproof.
