The BS EN 14654-3:2021 standard focuses on establishing requirements for managing and controlling activities in drain and sewer systems outside buildings. The standard covers the development and implementation of work programs, as well as the selection of techniques for drain and sewer cleaning. It is applicable to drain and sewer systems that extend from the point where wastewater exits a building, roof drainage system, or paved area to the point of discharge into a wastewater treatment plant or receiving water body.

This standard also includes drains and sewers below buildings, provided they are not considered part of the building's internal drainage system. The goal of this standard is to ensure the effective management and control of drain and sewer cleaning activities to maintain the proper functioning and integrity of these systems. By implementing the requirements specified in this standard, organizations can ensure the efficient and safe maintenance of their drain and sewer systems outside buildings.
