Drain and sewer systems outside buildings - Pumping installationsThis European Standard sets out the principles for the planning and design of pumping installations for drain and sewer systems which otherwise 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
