Drain and sewer systems outside buildings
|Publication Date:||30 April 2008|
|ICS Code (External sewage systems):||93.030|
This European Standard sets out 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, which operate essentially under gravity, 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.
Drains and sewers below buildings are included provided that they do not form part of the drainage system for the building.
