Drinking water must be pure, potable and free from pathogenic organisms. As regards quality and safety, the German water industry is a world leader. Consumers also have a high level of confidence in drinking water. The DVGW is committed to high German service levels combined with high technical and economic efficiency.
Improving the perception of drinking water
The German drinking water sector occupies a leading position worldwide. Drinking water is one of the best controlled foodstuffs in Germany. With the aim of maintaining this high level, the approximately 6,000 water utilities will face greater challenges than ever before in the coming years.
The climatic and demographic change combined with changed consumer habits and technical trends such as digitalisation, but also the increasing pollution of water resources by man-made pollutants place new demands on the utilities. In future, it will no longer be sufficient for water utilities to balance the tension between services for the public and economic efficiency solely by optimisation of their operational management. Rather, entrepreneurial decisions are required, which are increasingly taken in the political context. This makes it all the more important to promote expert political dialogue and, together with representatives from politics and business, to develop perspectives to secure the future of the sector.
In view of the economic and social importance of the public good “water”, the challenges facing the sector are a task for societyas a whole and can only be solved by consensus. This requires creating an awareness of the significance of drinking water in politics, business and society.
Basis for safety and sustainability
Establish drinking water protection areas
Protection of water catchment areas is an efficient instrument in water resources management in order to provide wholesome and cleandrinking water for the customer.
Monitoring with foreward view
Performance of monitoring in the catchment area assures early warning of hazards to the quality of water resources.
Cooperation with other stakeholders
Water resources are mainly affected by diffuse pollution, in particular from agriculture. Measures to protect water resources impacted by various local activities should ideally worked out in conjunction with stakeholders.
Over 300 DVGW Technical Rules cover all processes in water supply
Multi-step approach to water treatment
At the simplest level, natural treatment measures, e.g. filtration. At the most advanced level, state-of-the-art methods, e.g. membrane technologies.
Planning, construction and maintenance of installations inside buildings is the exclusive domain of qualified plumbers with technical know-how and expertise.
Use of DVGW-certified products and materials
The DVGW as certified body tests the behaviour of materials and products in contact with drinking water to assure fitness for this purpose.
Safety devices to secure the water distribution network
Backflow preventers and other devices ensure that no cross connections between the installations inside buildings and the water distribution network occur.
Position statement of 26. April 2019 by DVGW, fkss, ÖVGW, SGK and SVGW
In the context of cathodic corrosion protection, the shielding effect of delaminated coatings is frequently discussed. Especially in Anglo-Saxon countries, the use of non-shielding coating systems is prescribed for certain pipelines. This increasingly leads to the supersession of polyethylene-based coating systems in these countries. In recent years, discussions with regard to shielding are also increasingly taking place in Europe, accompanied by the increasing marketing of allegedly non-shielding products. However, the use of coatings with significantly poorer dielectric properties contradicts Central European practice.
