About IZEG

Standards for future-proof drainage of buildings

Together we want to create top standards in European drainage technology. In order to ensure reliable information and exceptional product quality for all market partners in the drainage industry, we founded the Information Centre for Cast Iron Drainage Technology (Informationszentrum Entwässerungstechnik Guss) - IZEG for short - in 2001.


We support you


Our members are the leading European manufacturers of drainage technology. Their product portfolios range from drainage pipes and fittings to connection technology and other accessories. All members are actively involved in the development of high-quality product and application standards beyond the scope of the IZEG in order to be able to guarantee the best and independently tested quality of their products to their partners on the market.

The Cast Iron Pipe Quality Seal

All products produced by IZEG members bear the RAL quality seal of GEG - Gütegemeinschaft Guss e.V. and are regularly tested and inspected. This means that their products and systems are quality-assured according to DIN EN 877 and RAL-GZ 698 and not only meet current standards, but clearly exceed them.
