Standard DWA-A 400E Principles for the Preparation of DWA Rules and Standards

The German Association for Water, Wastewater and Waste draws up uniform technical rules for the areas of water management, land development, soil conservation, wastewater and waste technology. Thus, a major contribution to the protection of material goods and the environment and to quality assurance in technology, economy, science and administration is made. The DWA Rules and Standards also serve education and training purposes. The present Standard is the basis for t he implementation of the statutory mission of creating, updating and publishing of the DWA Rules and Standards. It specifically regulates the nature of Standards and Advisory Leaflets, lays down the proceedings for their coming into existence and makes statements concerning the notice and information about them.
