This European Standard specifies the requirements, test methods, conformity assessment and marking of prefabricated secondary treatment units used for the treatment of effluent flowing from septic tanks in accordance with EN 12566-1 or EN 12566-4 in small wastewater treatment plants up to 50 PTE. It applies to the prefabricated secondary treatment unit, when all its components are ready for use or manufactured on site and placed on the market in kit form by a manufacturer. The prefabricated secondary treatment unit consis s of one or more tanks made of concrete, steel,
