The study of the hydrogeological conditions prevailing in karstic zones began many years ago, although the methods used have of course been frequently adapted to the state of the art. The characteristics of karstic regions have a strong effect on drinking water quality. For this reason, the Vienna Waterworks are exploring these characteristics together with other European countries (see ”Terrain model“)

Protection of the Danube

The International Association of Water Supply Companies in the Danube River Catchment Area is an association of waterworks in the Danubian countries; this catchment area extends from the springs in Germany’s Black Forest to the mouth of the Danube, which flows into the Black Sea in Romania. It is a key task of IAWD to improve the water quality of the Danube and its tributaries. Over 30 members do their best to carry out joint studies in the 14 riparian countries of the river. The results are continuously compared; important experiences are exchanged.

Co-operation

In order to make sure that the water-related knowledge that has been accumulated will be optimally used and further developed, the Vienna Waterworks participate in numerous national and international specialised bodies:

ÖVGW – Österreichische Vereinigung des Gas- und Wasserfaches This lobby of the Austrian water and gas companies develops technical guidelines and organises a wide variety of events.

ON/CEN – International Committee for Standardization Develops technical standards that serve as a basis for the construction and operation of water supply installations.

EUREAU – Union of the European Water Supply Associations from Countries of the European Communities Represents the interests of water companies vis-à-vis the institutions of the European Union.

IWA – International Water Association This worldwide association of water supply and wastewater management companies organises international and regional events and conferences.

ÖGL – Austrian society for the trenchless laying and maintenance of pipelines ÖGL was established in 1991 as an independent association under the Associations Law. (Source: Vienna Waterworks Municipal Department 31)
