DIN EN 12255-1:2002-04

This European Standard specifies general requirements for structures and equipment as they relate to wastewater treatment plants for a total population of more than 50 PT. The primary application is designed for wastewater treatment plants for the treatment of domestic and municipal wastewater. Requirements for structures which are not specific for wastewater treatment plants are not within the scope of this European Standard. Other ENs may apply. Equipment which is not solely used in wastewater treatment plants is subject to the applicable product standards. However, specific requirements for such equipment when used in wastewater treatment plants are included in this part. General principles of building construction, mechanical and electrical engineering are not subject of this standard. This European Standard does not cover the design of treatment processes.
