DIN Standards Committee Water Practice

About NAW

The DIN Standards Committee Water Practice (NAW) is responsible for the standardization in the concise field of water-related aspects and promotes the propagation and application of these standards. The technical work is performed in the committees Environment (waste, soil and water quality), Water engineering, Water supply and Waste water engineering. The NAW takes care of the national contribution to European and International standardization in these fields.
