BS EN 752-2:1997

This part of BS EN 752 sets out the performance requirements to be taken into account when planning, designing, installing and operating drain and sewer systems that operate essentially under gravity.

This European Standard is applicable to drain and sewer systems, which operate essentially under gravity, from the point where the sewage leaves a building or roof drainage system, or enters a road gully, to the point where it is discharged into a treatment works or receiving water.

Drains and sewers below buildings are included provided that they do not form part of the drainage system of the building.
