History

Andreas Bichler joins the management team at Dehoust GmbH. The area of industrial water management is the focus of development. The company sees great potential for development, particularly in drinking water separation stations and the decentralized dual use of grey water.

After 50 years in the South Industrial Estate in Leimen, Dehoust is able to put a new warehouse and production hall into operation. The possibilities for the production of systems for decentralized process water management (rainwater and greywater use and drinking water separation stations) are significantly increased.
This hall meets ecological requirements with a PV system and heat pump heating.
Further roof areas will be fitted with PV systems in 2023.
