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 rehabilitation activities.
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.
