Restore sewerage or drainage assets to a serviceable condition

This Standard is about restoring the function of sewerage or drainage assets either on a planned basis or in response to notification of a system failure. Sewerage and drainage assets could be in public networks or privately owned. Activities could include making repairs or clearing blockages. Methods of remedial action could include rodding, water-jetting, cleaning, reporting of condition causing failure or disinfection of surrounding areas.
It includes identifying the right method and tools to carry out the work, carrying out the maintenance and verifying and testing the restored sewerage or drainage assets.
This Standard is aimed at operatives who restore sewerage or drainage assets to a serviceable condition including those working in sewerage pumping stations.
