The Water Technology Center (TZW) is the center of applied water research of the DVGW, the German Gas- and Waterworks Association. The DVGW was founded in 1859 as the technical-scientific association of the German gas and waterworks. The DVGW is political and economical independent. The association follows non-profit goals only.

The TZW co-operates with water works by doing joint research projects. The TZW supports the DVGW in development and transfer of the Technical Guidelines of the DVGW. Moreover, the TZW is contact point for authorities, ministries and associations in all questions concerning surface and ground water, drinking water and water technology. The TZW provides a link between the DVGW, the basic research at the universities and the water treatment companies. In his work the TZW has to fulfill the statute of the DVGW, requiring a strict independence and objectiveness.

The TZW was established from the DVGW-Research Institute at the Engler-Bunte Institute of the University of Karlsruhe in 1994. The TZW is located in Karlsruhe in the southern part of Germany. The Heinrich-Sontheimer-Laboratory and the department of material testing are situated in a waterworks of the Stadtwerke Karlsruhe, a local supplier of drinking water.
