The German Gas and Water Association e. V. - technical-scientific association ( DVGW ) is the branch association of the German gas and water industry based in Bonn . The association also has offices in Berlin , Brussels and a number of state capitals . As a recognized regulator for the gas and water sector and the largest industry certifier, the DVGW plays a key role in fuel gas and water supply in Germany. In addition, the association acts as the main initiator of industry-related innovations, research projects and as a service provider in the field of vocational training.

The DVGW was founded in Frankfurt a. M. and currently has around 14,000 members, including 2,000 utilities, 1,400 companies, 250 government agencies, institutions and organizations, and 10,000 personal members. The association in the legal form of a registered association is independent and recognized as non-profit .


Regulation and standardization

The main task of the association is the creation of the technical regulations with which the safety and reliability of the gas and water supply in Germany is guaranteed. The experts of the interested groups create the DVGW set of rules in voluntary cooperation. This means that the technical rules for the gas and water sector can be drawn up by the industry itself (technical self-administration).

In the gas compartment, compliance with the legally prescribed generally recognized rules of technology (aaRT) is assumed in accordance with Section 49 (2) EnWG when the DVGW rules are applied . In the water sector too, the legislator requires compliance with the aaRT with regard to the specification of technical and scientific requirements . Adherence to these rules is not mandatory; However, they are the benchmark in the event of damage and they can have a quasi “legal character” with regard to liability law, provided the underlying law provides for this. For example, in the event of damage, it must be proven that at least the aaRT has been complied with.

In addition to developing the (national) set of rules, the DVGW is also working on the creation of DIN, EN and ISO standards. The DVGW set of rules currently comprises 600 currently valid rules and standards. The management of the Gas Technology Standards Committee (NAGas) at DIN is the responsibility of the DVGW.

Testing and certification

Another statutory task is testing and certification . Currently over 7,400 products, over 1,500 companies, 170 experts, 220 management systems and 500 prequalifications certified. According to European law, there must be an organizational separation between standardization work and testing with certification. For this reason, the certification activities of the DVGW were outsourced to the newly founded DVGW CERT on August 1, 2007, a wholly owned subsidiary of the DVGW.

Research and Development

The promotion of research and development work is also included in the DVGW statutes. To achieve this statutory goal, z. B. individual research projects are funded or institutional grants are awarded to the research institutes cooperating with the DVGW. The institutes funded by the DVGW are:

Research institutes gas / water
DVGW Water Technology Center (TZW), Karlsruhe
DVGW Research Center TUHH, branch of the TZW at the Technical University Hamburg-Harburg at the Institute for Water Resources and Water Supply
DVGW research center at the Engler-Bunte-Institut (EBI) of the KIT - Campus South, Karlsruhe
DBI Gas- und Umwelttechnik GmbH DBI GUT, Leipzig
DBI Gastechnologisches Institut gGmbH DBI-GTI, Freiberg

Publications, training and events

The DVGW publishes specialist literature on its field and also offers vocational training and further education. This serves u. a. the own DVGW academy. In addition, the DVGW is also the organizer of congresses and specialist conferences. The DVGW occasionally acts as a patron, for example at the Wasser Berlin International trade fair .

Honor roll and other honors

For extraordinary commitment in the gas and water sector, the association awards the Bunsen-Pettenkofer honor board , donated in 1900, at irregular intervals . It is named after Robert Wilhelm Bunsen (1811–1899), the inventor of spectral analysis , and the Bavarian chemist Max von Pettenkofer (1818–1901). Between 1900 and 2011 it was awarded a total of 71 times.

In addition, there has been honorary membership of the DVGW since 1861 , as well as the ring of honor and the badge of honor. There is also the Kuhn Medal of Honor for specialists in cathodic corrosion protection .
