Sewage and treatment

The central task of sewage technology is the storage, transporting and cleaning of wastewater as well as industrial sewage and rainwater runoff. Depending on the type of wastewater the valves used have to meet very specific requirements. 

For use in sewage technology protection against blockage of the passage is the order of the day. Smooth and abrasion-resistant passage surfaces are also required. Particularly in the case of heavily contaminated sewage, great importance is attached to the choice of suitable materials and optimum protection against corrosion. The competence of ERHARD is proven in numerous projects that have been realised throughout the world.
