Overview

This European Standard specifies the objectives for drain and sewer systems outside buildings. It specifies the functional requirements for achieving these objectives and the principles for strategic and policy activities relating to planning, design, installation, operation, maintenance and rehabilitation. It is applicable to drain and sewer systems from the point where wastewater leaves a building, roof drainage system, or paved area, to the point where it is discharged into a wastewater treatment plant or receiving water body. Drains and sewers below buildings are included provided that they do not form part of the drainage system for the building. The responsible German standardization committee is Working Committee NA 119-05-35 AA "Planung und Betrieb von Abwasserkanälen und -leitungen" ("Design and operation of drains and sewers") at DIN Standards Committee Water Practice (NAW).
