Wastewater treatment

Perfect renewal of water resources. Wilo is synonymous throughout the world with the tradition of first-class German engineering. Wilo pumps and systems set new standards for municipal wastewater treatment with regard to technical performance and efficiency. With regard to environmental protection and conservation of resources, wastewater treatment plays an important role.
