This document establishes requirements for the management and control of activities in drain and sewer systems outside buildings and specifies requirements for development and implementation of work programmes, and the selection of techniques.
This document covers the management and control of drain and sewer cleaning.
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.
Drains and sewers below buildings are included provided that they do not form part of the drainage system of the building.
