Comment end date 2025-09-21

Drain and sewer systems outside buildings — Sewer system management

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. The standard pays regard to the extremes of our changing climate and seeks to aknowledge the associated impacts on existing drain and sewer systems outside of buildings and futureproof associated aspects of those systems that are to be planned for and designed in the future. Drains and sewers below buildings are included provided that they do not form part of the drainage system for the building.
