BS EN 14654-1:2021 PDF Download

BS EN 14654-1:2021 is a standard that sets out the general requirements for the management and control of activities in drain and sewer systems outside buildings. The standard focuses on the development and implementation of work programmes and the selection of techniques to ensure effective management and control.

This standard applies to drain and sewer systems starting from the point where wastewater leaves a building, roof drainage system, or paved area, and extends to the point where it is discharged into a wastewater treatment plant or receiving water body. It also includes drains and sewers below buildings, as long as they are not part of the building's own drainage system.

The purpose of this standard is to provide guidance on the proper management and control of activities in drain and sewer systems, ensuring they are maintained and operated in a safe and efficient manner. Compliance with this standard helps to prevent blockages, reduce the risk of pollution, and promote the effective functioning of wastewater treatment processes.
